Title:
GAS-LIQUID TWO-PHASE SATURATION COAL ROCK SAMPLE EXPERIMENT DEVICE AND SATURATION TEST METHOD
Document Type and Number:
WIPO Patent Application WO/2020/151138
Kind Code:
A1
Abstract:
A gas-liquid two-phase saturation coal rock sample experiment device and saturation test method, comprising a core holder (1). The two ends of the core holder (1) are connected to a fluid entry device (2) and a fluid discharge device (3) respectively by means of dense copper tubes; the fluid entry device (2) comprises a first main device tank (21) and multiple gas-liquid booster tanks (22); the first main device tank (21) is provided with a humidity detector (211), a pressure detector (212), and a methane concentration detector (213); the gas-liquid booster tank (22) comprises a gas booster tank (221) and a liquid booster tank (222); the fluid discharge device (3) comprises a second main device tank (31) and a vacuum pump (32); the second main device tank (31) is provided with a humidity detector (211), a pressure detector (212), and a methane concentration detector (213); the vacuum pump (32) is used for creating a low-pressure environment in the second main device tank (31). A conventional liquid is replaced with an atomized liquid, and thus, the resistance of a fluid passing through a porous medium is reduced, damages of the fluid to the structure and the physical properties of a coal rock sample can be reduced as much as possible, and the liquid saturation and gas-liquid displacement difficulty is reduced.
