Seepage Mechanism and Transient Pressure Analysis of Shale Gas
The current research of nonlinear seepage theory of shale-gas reservoir is still in its infancy. According to the characteristics of shale gas in adsorption-desorption, diffusion, slippage and seepage during accumulation, migration and production, a mathematical model of unstable seepage in dual-porosity sealed shale-gas reservoir was developed while considering Knudsen diffusion, slip-flow eff...
متن کاملStrength, creep and frictional properties of gas shale reservoir rocks
The deformational properties of gas shale reservoir rocks from the Barnett and Haynesville shale formations were investigated using a triaxial apparatus. The samples tested varied in their mineralogical composition, the degree of diagenesis, the total organic content and the degree of maturity of the organic material. In general, rocks with more cement and less clay show higher elastic moduli, ...
متن کاملCharacteristics of Shale Gas Reservoir in Jiyang Depression and its Significance in Drilling and Exploitation
Physical and geochemical characteristics of shale play conclusive role in confirming operation measures during drilling and stimulation. The properties of shale samples from Jiyang depression were investigated through X-ray diffraction, scanning electron microscope, adsorption isothermal, high pressure mercury intrusion, methylene blue trihydrate, pressure pulse decay, tests of specific water w...
متن کاملA numerical study of performance for tight gas and shale gas reservoir systems
Various analytical, semi-analytical, and empirical models have been proposed to characterize rate and pressure behavior as a function of time in tight gas and shale gas systems featuring horizontal wells with multiple hydraulic fractures. Despite a few analytical models, as well as a small number of published numerical studies, there is currently little consensus regarding the large-scale flow ...
متن کاملShale Gas Productivity Predicting Model and Analysis of Influence Factors
Abstract: In order to find the dynamic characteristics of shale gas reservoirs and improve shale gas well production, it is very important to research on shale gas seepage mechanism and production evaluation. Based on the shale gas seepage mechanism, adsorption and desorption characteristics, the diffusion mechanism and mass conservation theory in shale gas development, the dual pore medium sha...
