  • Numerical Simulations of Liquid Leakage and Gas Channeling for Plunger
           Lift

    • Free pre-print version: Loading...

      Abstract: Plunger lift is one of the commonly used processes for liquid extraction and gas production in gas wells. Owing to the gap between the plunger and the tubing wall, liquid leakage and gas channeling during the lifting process are inevitable. Liquid leakage reduces the amount of lifted liquid, and gas channeling is not conducive to the complete utilization of formation energy. Furthermore, the gas that breaks through the gap into the top of the plunger also hinders plunger movement. To address this problem, we used CFD to simulate plunger movement in the tubing and analyzed the influence of various factors, such as plunger velocity, pressure difference between the upper and lower ends, and plunger diameter, on liquid leakage and air channeling. The results indicated that when the plunger rises and drains the liquid, the plunger velocity increases, the leakage between the plunger and the tubing increases, and the gas channeling volume decreases. When the pressure difference between the upper and lower ends of the plunger increases, leakage loss is reduced. The larger the plunger diameter, smaller the interval between the plunger and the tubing, and smaller the less leakage loss. The results of the study validate the influencing factors of plunger lift leakage and gas channeling, optimizing the plunger structure and improving the efficiency of plunger lifting.

  • Application in Oil Field Drilling with Temperature-Resistant Natural
           Modified Filtrate Reducer: A Review

    • Free pre-print version: Loading...

      Abstract: Natural modified filtrate reducer is an important additive in the process of oil drilling. It can reduce the fluid loss of drilling fluid, improve filter cake and protect borehole wall. However, with the continuous increase of drilling depth and the gradual increase of temperature, natural modified filtrate reducer began to appear poor stability, lower filtration effect and other problems. Therefore, scholars have studied the natural filtrate reducer to improve the temperature resistance of the natural filtrate reducer, so that the natural modified filtrate reducer can adapt to the high temperature formation. Moreover, some natural modified filtrate reducer also have calcium and salt resistance. This review provides a comparative investigation and summary for asphalt, humic acid, lignin, cellulose and starch filtrate reducers. In addition, the author also introduces the mechanism of natural modified filtrate reducers, preparation process of natural modified filtrate reducers, optimization and improvement of natural modified filtrate reducers and their application fields. Last, the author looks forward to the current key issues and future development direction.

  • Research on Dynamic Prediction Model of Wax Deposition in Wellbore

    • Free pre-print version: Loading...

      Abstract: Wax deposition in oil wells has become an important issue, which affects the production of oil fields. According to the wax deposition in the wellbore of an oilfield in Northwest China, a dynamic prediction model of the wellbore wax deposition was established based on the molecular diffusion mechanism. The compiled software can predict the temperature and pressure of the fluid, wax deposition point, wax deposition weight, wax deposition volume, wax deposition speed, and wax removal cycle of self-blowing wells and pumping well bores and sucker rods at different well depths. The software is used to predict the influence of flow temperature and pressure, wax deposition point, wax deposition volume, wax deposition rate, wax removal cycle and water content, gas-liquid ratio and oil production on the wax deposition rate of the wellbore of M1 well in a certain northwest oilfield. The results show that the prediction results of the model are reliable. The prediction accuracy of the flow temperature and pressure of the M1 well is higher than 92%, and the prediction accuracy of the wax removal cycle is up to 89%. The law of influence is consistent with the literature results. Therefore, the research results of this article provide a quantitative basis for the formulation of wax removal cycle in an oilfield in Northwest China, and provide theoretical and technical support for optimizing wax removal and control technology.

  • Co-Deposition Mechanism of Waxes with Asphaltenes and Scales in a Vertical
           Wellbore of Gas Condensate Well

    • Free pre-print version: Loading...

      Abstract: With the increased exploitation of gas condensate resources, the problem of wax deposition in wellbores is increasingly severe. Hence, this paper reveals the co-deposition mechanism of vertical gas condensate wellbores with waxes, asphaltenes and scales from a microscopic viewpoint by molecular dynamics (MD) simulation techniques. Several experiments were also utilized to determine the basic physical properties of the condensate. To avoid inaccuracies caused by simplifying the condensate multiphase system using a single component, eight typical components were selected to enhance modelling precision according to actual well fluid characteristics. The wellbore, condensate, asphaltene and scale systems modelled by the MD simulation techniques were validated with the corresponding data from the National Institute of Standards and Technology (NIST), and this actual error of the results after stimulating was less than 10 %, which met the error criteria and verified the construction of the system model as realistic and feasible. The simulations investigate the co-deposition mechanism of waxes with asphaltenes and scales in vertical wellbores at three levels: diffusion mechanism, aggregation properties and co-deposition behavior. The simulation results show that as the waxy components in the models increases, the aggregated and adhered condensate layer at the wellbore becomes thinner and the “replacement” between the waxy components and condensate molecules begins happening, and this deposition phenomenon gradually strengthens. When in the asphaltene-condensate system, the promotion effect on the deposition of wax molecules becomes more obvious as these asphaltene components increases, but up to 2% asphaltene components, the wax deposition behavior is inhibited conversely. Simultaneously, asphaltenes with a larger variety and number of heteroatoms contribute more significantly to this co-deposition behavior of waxy components and asphaltene components. For these scale-condensate systems, the most prominent influence for the aggregation and deposition behavior of waxy components is exerted by sulphate scale, with the most noticeable co-deposition effect. Its interaction energy (absolute value) is the highest, reaching 3840 kJ/mol. The results in the article can offer a basis and instruction to this targeted management for wax deposits in vertical wellbores of gas condensate wells.

  • Experimental Research on the Impregnated Diamond Bit Wear Model

    • Free pre-print version: Loading...

      Abstract: The low rate of penetration (ROP) and severe wear of polycrystalline diamond compact (PDC) bits are one of the main problems restricting the exploration of deep oil and gas resources when drilling strongly abrasive formations. As a rock-breaking tool that breaks rocks in the way of diamond exposure, the impregnated diamond bit has the characteristics of high stability, long service life and high drilling speed, which are considered to improve the drilling efficiency of strong abrasive formations. one of the effective ways. However, the drilling parameters and rock abrasiveness of the impregnated drill bit have a very significant impact on the wear rate of the impregnated diamond bit. If the drilling parameters are not designed properly, the bit will be severely worn and the service life will be too low. At the same time, there is a lack of research on the wear equation of diamond-impregnated drill bits, which cannot predict the wear rate of the drill bit and the life of the drill bit well. Therefore, this paper analyzes and summarizes the experimental data of the influence law of drilling parameters and rock abrasiveness coefficient on the wear of impregnated diamond bits, and establishes a formula based on the quantitative relationship between wear rate and WOB per unit area, rotary speed and rock abrasiveness. The impregnated diamond bit wear model provides a theoretical basis for the life prediction of the impregnated diamond bit in field drilling operation.

      Abstract: Saddle Diesel is a diesel engine plant in a local city in northeast China, which is already the special designation. In this paper, a new polyhydroxy polyacid macromolecule called citric acid-1,4-butanediol-citric acid-cycloalkanic acid-tetradecyl alcohol (CTC-NT) with 1,4-butanediol as the core was designed and synthesized via an “ester-ester” copolymerization process using 1,4-butanediol and citric acid as the raw materials and then grafted sequentially with naphthenic acid and tetradecanol containing functionalized groups. The structures of the synthesized compounds were characterized by nuclear magnetic resonance and infrared spectroscopy, and the results showed that the synthetic products were consistent with the designed molecular structure. The use of the prepared CTC-NT in saddle oil light diesel was studied. The results showed that the filtration improvements of the synthesized multibranched macromolecule CTC-NT were better than those of other additives for the same oil, and the cold filter point was reduced by up to 13°C when the dosage was 900 μg/g.

  • Bottlenecks and Technological Developments for Geologic Storage of CO2

    • Free pre-print version: Loading...

      Abstract: There is global consensus that geologic storage is an underpinning technology for large-scale reduction of CO2 emissions. Although CO2 flooding and storage has been employed to promote crude oil recovery, storage of CO2 in aquifers has proven to be the main and fundamental technical route for large-scale geologic storage due to convenient site selection, easy source-sink matching, huge implementation scale, and low storage costs. In view of the deposition characteristics of terrestrial aquifers in China and the practices of underground storage of natural gas, this study identifies three bottlenecks hindering large-scale aquifer storage of CO2 in China (i.e., aquifer storage capacity, storage costs, and long-term safety), and proposes five key fields where technological breakthrough is needed (i.e., assessment of storage capacity, low-concentration CO2 injection, large-scale high-speed CO2 injection, low-cost engineering support, and long-term safety monitoring) to overcome key obstacles in meeting China’s “3060” goals – carbon peaking by 2030 and carbon neutrality by 2060.

  • A New Re-Liquefaction System for Dynamic Boil-Off Recovery Based on Single
           Mixed Refrigerant

    • Free pre-print version: Loading...

      Abstract: The single cycle mixed-fluid LNG (PRICO) process is the most widely used for natural gas liquefaction. But the optimized energy consumption of single mixed refrigerant (SMR) liquefaction process was still high using the existing energy saving optimization method. The main purpose of this study was to propose an optimization method to combine with the combination optimization of important parameters to improve the system energy efficiency for the SMR structure. The liquefaction process with an initial investment increase of only 6% was designed, by adding initial investment including separator, valve, mixer, etc. The genetic algorithm and liquefaction simulation were used to analyxze the combination optimization of multiple parameters, such as the component ratio of the mixed refrigerant and the pressure of the liquefaction circulation node. Finally, by comparing the similar liquefaction process, it can be found that the optimized heat exchanger internal hot and cold complex curve was better matched, thus reducing the energy Irreversible loss. It indicated that operation energy consumption of the improved SMR process, of which the specific energy consumption could reach 0.247kW·h/kg, was 10.24% lower than PRICO, and the total energy consumption was decreased by 2%. It is thus clear that the optimization method of liquefaction process design and parameter combination has great energy saving efficiency.

  • Study on Performance Evaluation of Profile Control System with High
           Temperature Resistant Weak Gel Prepared from the Produced Fluid

    • Free pre-print version: Loading...

      Abstract: The use of highly mineralized reinjection water has low gel strength and poor stability, and the above problems are more prominent under high-temperature reservoir conditions. Based on the temperature resistance and salt tolerance polymer TSRP and phenolic resin crosslinking agent, a TSRP temperature resistant weak gel system suitable for high mineralized reinjection water was developed, and the temperature resistance mechanism of the TSRP weak gel system was tested by its temperature resistance and injection ability. The migration, retention, and plugging of the TSRP weak gel system in heterogeneous reservoirs were studied through micropore throat migration and plugging characteristics and dual-pipe parallel oil displacement experiments. The results showed that: under the condition of polymer concentration 2000 mg/L, polymer: crosslinking agent: glue promoter 1:1.5:1, the TSRP weak gel system prepared by using mineralized 12132.9 mg/L reinjection water can remain stable after 95°C aging at high temperature of TSRP. Through microscopic simulation, a glass etching model TSRP weak gel system showed good migration ability and plugging performance. In comparison with the two pipes parallel oil displacement experiment, the KY gel system injected the same amount of PV at 95°C and 20000 mg/L in the Y1L block, the average recovery of the TSRP gel system increased by 22.3% after injection of polymer gel, and the KY gel system was only 18.2%; When the same amount of PV was injected in Z1L block, 95°C and 22000 mg/L, the average recovery of TSRP gel system increased by 24.35% after injection of polymer gel, and the KY gel system was only 17.15%, that is, under higher salinity, the TSRP gel system showed better performance.

  • Study into the Specific Surface Area and Pore Space of Carbon Additives
           for Veba Combi Cracking (VCC)

    • Free pre-print version: Loading...

      Abstract: This paper presents a comparative study into the specific surface area (BET) and the volume and pore size (BJH) of carbon additives for slurry-phase reactors of the Veba Combi Cracking (VCC) process. The main textural parameters of carbon additives affecting the conversion rate of asphaltene nanoaggregates in the reaction medium of the VCC process were determined. The size of asphaltene nanoaggregates was assessed by laser diffraction in a toluene solution, simulating the reaction mixture. It was shown that the original carbon additive proposed by the VCC technology licensor (USA) and its Russian analogue provide for asphaltene conversion only at the expense of the outer specific surface, since their pore space remains inaccessible due to the small pore size. The treatment of carbon additives with water steam at a temperature of 800°C and heat treatment in nitrogen atmosphere at a temperature of 400°C led to a significant increase in the volume of their pore space and pore diameter, thus facilitating adsorption of asphaltene nanoaggregates on the interstitial surface. Involvement of the pore space of carbon additives into the adsorption of asphaltenes enhances their conversion in the reaction medium of the VCC process.

      Abstract: Aspects of the content and distribution of heteroatomic components in resins were studied for the case of heavy oils of the Tatarstan and Samara regions, and aspects of the group–structure composition of the fractions isolated from the resins are indicated. By fractionation of the resin it was possible to estimate the degree to which the content of the heterorganic component affects the flocculation of asphaltenes. Kinetic studies by UV spectroscopy showed that the fraction of high-molecular organonitrogen bases is most efficient in inhibiting the deposition of asphaltenes and surpasses the initial petroleum resins.
