Hydrocarbon generation patterns are crucial for defining favorable exploration maturity intervals and targets shale oil. The Permian Fengcheng Lucaogou in the Junggar Basin, as significant oil exploration, study on their hydrocarbon generation, expulsion, retention characteristics insufficient. This establishes using a semi-open thermal simulation system, combined with rock pyrolysis, vitrinite reflectance (Ro), total organic carbon (TOC) analysis, isotope gas chromatography-mass spectrometry (GC-MS), mercury porosimetry, nitrogen adsorption. Additionally, multivariate regression model was employed to systematically evaluate primary controlling factors of expulsion ratio. Based these results, were identified. results indicate that potential superior shale, whether considering yield or yield. However, began degradation earlier than has broader window. corresponding (T R ) is slightly higher shale. exhibited significantly ratios compared maximum ratio 2.1 times Mesopore volume its connectivity critical affecting ratio, whereas mobility macropore have relatively limited effects. optimal interval Ro = 1.0%–1.1% 0.9%–1.1% Exploration should focus lithofacies assemblages, dolomitic mixed rock-shale assemblages shore-shallow lake facies represent target. source-reservoir reservoir-to-shale thickness being These findings provide support development decisions Basin.

In this paper, the spinning drop method was used to measure oil–water interfacial dilational modulus of four different types surfactants with low tension (IFT), including anionic surfactant sodium dodecyl sulfate (SDS), nonionic Triton X-100 (TX100), zwitterionic alkyl sulfobetaine (ASB), and extended polyoxypropyl ether (S-C13PO13S). Based on experimental results, we found that is an effective means measuring interface IFT value lower than 10 mN/m. For common SDS TX100, decreases rapidly near zero increase in concentration when 1 On other hand, ASB has highest dilatation 50 mN/m, which comes from flatness its unique hydrophilic group structure. The S-C13PO13S showed a moderate plateau 30 mN/m broader change. This due fact main relaxation process dominating film properties long helical chain.

Abstract Oil production from tight reservoirs due to their very low permeability and high capillary pressure requires complex operations materials, so that hydraulic fracturing in these is recommended before any chemical injection. This operation turns the reservoir into a fractured one can produce more oil by activating imbibition mechanism. The interfacial tension (IFT) of water rock wettability as key parameters overproduction this type affect In study, potential 2‐butoxyethanol mutual solvent for enhanced recovery (EOR) was investigated with focus on under through performing experiments calculations IFT, swelling, contact angle, production. analysis results shows mechanisms IFT reduction, alteration, which all directly imbibition, reached desired values using appropriate concentration along dilution seawater. lowest angle at 0.03 M 5000 ppm salinity 90°C temperature were 1.315 mN/m 71.57°, respectively.
