SIMULATION EXPERIMENT TEST SYSTEM AND TEST METHOD FOR GAS HYDRATES IN POROUS MEDIUM

摘要

A simulation experiment test system and test method for gas hydrates in a porous medium. The test system mainly comprises a reaction kettle, a sensing system, a hardware interface device and a data processing system. The reaction kettle is used for holding a tested medium; the sensing system is mounted in the reaction kettle; and the sensing system accesses the data processing system via the hardware interface device. The test method mainly comprises the step of experiment and measurement data acquisition and the step of measurement signal analysis processing. By building an electrical model I and an acoustic model II, and by means of a gas hydrate saturation model III obtained by combining both, the simulation of a natural gas hydrate generation and decomposition process in a deposit sediment under a laboratory environment and the implementation of joint testing of acoustic and electrical parameters are realized, thereby finally building an accurate natural gas hydrate saturation calculation model.
