The high pressure static adsorption curves of shale samples from Silurian Changning-Weiyuan Longmaxi Formation were tested by using isothermal equipment. physical modeling depletion production was on single cores and multi-core series self-developed gas fluid-solid coupling experiment system. desorption laws summarized a model established. calculation formula content corrected, the producing law determined. study results show that reservoir under different conventional low pressure. curve...
It is of engineering interest to explore recovered shale gas composition and its effects on total production trend over a long-term extraction period. However, there are previous experimental studies mostly focused short term development for small scaled cores, which less convincing mimic reservoir-scaled process. In addition, the models failed account comprehensive nonlinear effects. As result, in this paper, illustrate full-life-cycle decline phenomenon reservoir, dynamic physical...
The development ofshale gas involves two critical processes including fracturing andtransportation. To realize reticular fractures in the shale layerof multi-phase under more than 2000 m subjected to complexgeo-stress and collect free adsorbed gases encapsulatedin layer, we face many key mechanical challenges beaddressed. There are several cut-on-edge research topicsassociated with development: huge span structuralsize fracture eveents from nanoscale even severalkilometers, transporting at...
Recently, deep shale reservoirs are emerging as time requires and commence occupying a significant position in the further development of gas. However, understanding pore characteristics remains poor, prohibiting accurate estimation hydrocarbon content insights into fluid mobility. This study focuses on Longmaxi Formation from Luzhou (LZ) region, southern Sichuan. Scanning electron microscopy (SEM), low-temperature N2/CO2 adsorption, X-ray diffraction, geochemical analysis were performed to...
Abstract In this paper, shale samples of Lower Silurian Longmaxi Fm, taken from the Changning–Weiyuan area in Sichuan Basin, were selected to figure out influence reservoir primary water on adsorption laws and flow capacity gas. Experimental with different saturations prepared using equilibrium method. Then, high-pressure isothermal experiments carried out, effects mechanisms under discussed. Finally, gas was tested independently developed steady-state test device. And following research...
So far, how imbibition effect changes the occurrence state of shale gas has not been quantitatively understood, and law gas–water dynamic displacement caused by retention abundant fracturing fluid in a reservoir determined clearly. In this paper, experiment was performed to simulate change water content near wellbore after hydraulic fracturing. Then, based on low field nuclear magnetic resonance spectrum analysis technique hydrogen-bearing (1H-NMR), methane reservoirs dynamically monitored...
The occurrence and flow of shale gas are substantially impacted by nanopore structures. fractal dimension provides a new way to explore the pore structures reservoirs. In this study, eight deep samples from Longmaxi Formation Wufeng in Southern Sichuan were selected perform series analysis tests, which consisted small-angle neutron scattering, low-pressure nitrogen adsorption, XRD diffraction, large-scale scanning electron microscopy splicing. elements that influence discussed two levels...
In the calculation of shale gas resources/reserves, isothermal adsorption parameters are mainly determined by dry sample data at laboratory temperature, and regression effect total organic carbon content (TOC) is poor. Based on physical significance key in Langmuir Henry models, problems determining reserves/reserves analyzed taking marine Upper Ordovician Wufeng Forming–Lower Silurian Longmaxi Formation Sichuan Basin as an example. a large number measured data, effects TOC, temperature...
Pore characteristics are one of the most important elements in study shale reservoir properties and a key parameter for evaluation potential oil gas resources. Low-temperature nitrogen adsorption is common laboratory method that used to characterize pore structure shale. However, effect shale’s particle size on experimental results deep samples still unclear. In this paper, using different mesh sizes from Luzhou Block as an example, we studied shale, characterized by experiments. The showed...
