Dry Volume Fracturing Simulation of Shale Gas Reservoir

[摘要] Application of CO2dry fracturing technology to shale gas reservoir development in China has advantages of no water consumption, little reservoir damage and promoting CH4desorption. This paper uses Meyer simulation to study complex fracture network extension and the distribution characteristics of shale gas reservoirs in the CO2dry volume fracturing process. The simulation results prove the validity of the modified CO2dry fracturing fluid used in shale volume fracturing and provides a theoretical basis for the following study on interval optimization of the shale reservoir dry volume fracturing.
