“…In a separate study, Yu et al [152] utilized the random forest (RF) machine-learning algorithm to explore the factors influencing the high and stable production of a single well within a specific well group in the Junggar Basin. Their findings indicated that reservoir quality and oil saturation are the primary controlling factors, establishing the fundamental basis for achieving high and stable oil production [153]. These studies demonstrate the significant advantages of the random forest model in evaluating the importance of multiple variables in large datasets.…”

“…Currently, most projects in this realm remain at the laboratory stage, constrained to some extent by the intricate reservoir conditions. Bridging the gap between real geological conditions (<200 • C) and laboratory settings (30-110 • C) is paramount for industrial implementation [153]. While existing experiments predominantly employ single-factor variable methods, focusing on simplified temperature, pressure, and crude oil compositions, the actual reservoir conditions exhibit significant temperature and pressure variations due to depth, coupled with more complex crude oil compositions.…”

Crude oil gasification bacteria, including fermenting bacteria, hydrocarbon-oxidizing bacteria, reducing bacteria, and methanogenic bacteria, participate in multi-step reactions involving initial activation, intermediate metabolism, and the methanogenesis of crude oil hydrocarbons. These bacteria degrade crude oil into smaller molecules such as hydrogen, carbon dioxide, acetic acid, and formic acid. Ultimately, they convert it into methane, which can be utilized or stored as a strategic resource. However, the current challenges in crude oil gasification include long production cycles and low efficiency. This paper provides a summary of the microbial flora involved in crude oil gasification, the gasification metabolism pathways within reservoirs, and other relevant information. It specifically focuses on analyzing the factors that affect the efficiency of crude oil gasification metabolism and proposes suggestions for improving this efficiency. These studies deepen our understanding of the potential of reservoir ecosystems and provide valuable insights for future reservoir development and management.

“…Several studies have investigated the conversion of crude oil in the presence of water and/or mineral matter. − Some studies asserted that the beneficial effects of water during the conversion, such as increased liquid product yield and coke suppression, are a result of its role as a reactant, while others argued that the water influence was due to physical solvent effects. − While the impact of mineral matter during oil conversion has received less attention compared to the influence of water, some studies in the literature have explored this aspect. − ,− These studies have covered a range of topics, including catalytic cracking and subsurface combustion of heavy oils, thermal oxidation of oils, and the thermal treatment of bitumen froth.…”

Research examining the impact of water and mineral matter on the thermal conversion of crude oil has indicated that retaining these components during treatment affects cracking, hydrogen transfer, and addition reactions. However, the complex nature of a reaction medium containing crude oil poses a challenge in relating the influence of water and minerals to particular reaction pathways. To enhance understanding of the specific contributions of water and minerals to reaction chemistry during thermal conversion, a practical approach is to make use of simpler model systems to capture relevant information for petroleum processing. The current study explored the impact of water and kaolinite on the reaction rates and pathways during the thermal conversion of a model system comprising αmethylstyrene (AMS), tetralin, and n-pentadecane at 400 °C for 1, 5, 10, and 30 min. The effect of kaolinite at different concentrations was also compared to that of rutile and quartz during the conversion of AMS alone. Water and kaolinite, individually and collectively, affected the reaction rates. Water suppressed the AMS conversion rates, but no evidence was found that water affected reaction pathways. Kaolinite increased the conversion rates of both AMS and tetralin, while also enhancing the formation rates of cumene and naphthalene. This suggested that kaolinite somehow favored hydrogen transfer during the treatment. The presence of kaolinite also increased the formation rates of benzene by dealkylation and the tricyclic AMS dimer 1,1,3-trimethyl-3-phenyl indane, indicating that kaolinite was catalytically active, influencing reaction pathways by promoting cationic conversion. The adsorption of water on the surface of kaolinite appeared to contribute to reduced reaction rates when reacting AMS in the presence of both water and kaolinite. The deposition of carbonaceous material on kaolinite suggested that the mineral is rapidly fouled during the conversion.

“…1,2 In order to maintain high and stable oil production, it is crucial to prioritize the development of deep oil and gas resources. 3,4 However, as the country continues to explore and develop oil and gas in deep fields, the steel rods with heavy ratios, susceptibility to corrosion, and serious wear limitations are becoming increasingly apparent, leading to a significant reduction in oil field recovery. 5 Therefore, the use of ultra-high-strength, corrosion-resistant composite rods is an emerging trend for ultra-deep oil and gas wells.…”

The carbon/glass hybrid rod exhibits high tensile strength, light weight, and strong corrosion resistance. However, the bottleneck of interlayer splitting exists in the interlayer hybrid rod, severely impeding safe operation. To solve the problem of rod splitting, this paper proposed a new scheme of an intralayer carbon/glass hybrid rod. Based on the material constitutive model, a full‐scale simulation model was developed. The stress distribution and deformation of the hybrid rod were analyzed and the progressive damage mechanism of the hybrid rod was explained. The results indicated that, for the intralayer carbon/glass hybrid rod, (a) the ultimate experimental tensile load witnessed a significant increase, rising by 14.0% from 452.4 to 515.7 kN compared to the interlayer hybrid rod; (b) the numerical model predicted the tensile load of 525.9 kN, with an error of 1.9% compared to the test result, meeting engineering accuracy requirements; (c) the elastic deformation stage saw a 146.7% increase from 280.2 to 691.3 MPa in the maximum axial stress of the carbon‐fiber layer, and a 120% increase from 89.8 to 198.0 MPa in the maximum radial stress of the glass fiber layer as the tensile displacement increased from 0.16 to 0.32 mm. In conclusion, the intralayer carbon/glass hybrid rod proposed in this paper can significantly improve the tensile strength compared to the interlayer hybrid rod, which can accelerate the application of carbon/glass hybrid rods in oil and gas fields.Highlights According to the problem of interlayer splitting in the interlayer carbon/glass hybrid rods, a novel scheme of an intralayer carbon/glass hybrid rod was proposed. Based on the material constitutive model, a full‐scale simulation model of an intralayer carbon/glass hybrid rod was developed to analyze the stress distribution and deformation response under tensile load. The dynamic progressive damage analysis method for intralayer carbon/glass hybrid rods was proposed to reveal the damage evolution mechanism.
