  • Publication number: 20190330980
    Abstract: A device and a method for evaluating a gas-water two-phase flow fracture conductivity of a fractured shale. The device includes a seepage system, an injection system, a data collecting and processing system and a three-axis shale core holder, wherein the seepage system is subjected to two stages including a water injection stage and a gas flooding stage. When using the device, firstly the initial permeability and initial mass of the shale sample are determined; the water influx test is performed by injecting water to the shale sample until flow rate of the water discharged from the shale core is stable, then the water injection is ended. After the drying device is installed, the shale sample is subjected to gas flooding, and the aqueous fracturing fluid discharged by the gas flooding is collected until the flow meter determines that the gas volume is stable, and then the gas flooding is ended.
