Abstract The low permeability of shale, in accretionary complexes and passive continental margins, influences pore pressure generation, thus induces deformation fault slip behavior. It is also key hindering the ability to evaluate shale gas production. Gas commonly used measuring generally yields high values than that liquids, due slippage effect. Separation effect from a critical task study low‐permeability media. This measured ( K g ) Longmaxi parallel bedding (L1P) perpendicular (L1V)...
Matrix diffusivity is vital for developing tight sandstone and shale gas reservoirs. This study proposes a method to test the diffusivities of core under confining pressure conditions using diffusion technique. The methane helium were examined in fine-grained rocks (sandy shale, silty sandstone, shale) specific stress conditions. results revealed that varied among samples. sandstones exhibited higher than sandy mudstone, shale. Helium shales mudstones 1 order magnitude smaller, while 2...
C 5 –C 7 light hydrocarbons are important components in petroleum and extensively employed as an auxiliary approach research. Consensus on the mechanism of hydrocarbon generation has not yet been achieved. In this study, 20 gas samples were collected from western part northern margin Qaidam Basin. The molecular carbon isotopic compositions 1 3 gaseous hydrocarbons, well isotopes oils analyzed. Based relationships between ( 13 C) individual calculated vitrinite reflectance, it suggests that...
This article aims to improve the toughness of pre-packaged grouts (PPG) by incorporating crumb rubber. The mechanism for PPG with rubber was analyzed based on uniaxial compression model. Crumb surfaces treated different methods (NaOH solutions or microwave treatment) observed scanning electron microscopy (SEM). effects mesh sizes, amounts, surface-treated rubber, and mixing procedures PPG’s mechanical strength rheological properties were investigated. results showed that, firstly, addition...
Abstract The sealing failure of cement sheath which caused annulus pressure in shale gas wells have significantly affected the safe and efficient development gas. In view integrity is by high fluid casing during hydraulic fracturing treatment, an experimental device for testing established. addition, analytical model calculating stress strain well system established based on parameters device. circumferential at outer wall steel cylinder achieved. error stress-strain between calculated...
Abstract The organic acid is important in forming secondary pores and enhancing total porosity of the clastic rock. But there little study to investigate effect on distribution rock from deep reservoirs. changes porosity, permeability, dissolved medium-grained lithic arkose, Yanchang Formation Ordos Basin, were examined by nuclear magnetic resonance (NMR). results show that permeability increase with time exposure solution it increases rapidly early period, then slightly a saturation level....
