Abstract

The present invention discloses a simulation test system for dynamic monitoring coal reservoir sensitivity and drainage control. The simulation test system comprises: a sample loading, confining pressure loading and pressure measurement module, which is configured to load a test sample, apply a confining pressure to the test sample in a test process, and measure and record pressure data in the test process; a gas-liquid fluid displacement injection module, which is configured to wash a test pipeline, vacuum the test system, and inject the gas-liquid fluid used for the test into the sample loading, confining pressure loading and pressure measurement module; and a gas-liquid collection and measurement module, which is configured to collect gas and liquid from the sample loading, confining pressure loading and pressure measurement module, and measure the amount of the collected gas and liquid. According to the test system provided by the present invention, the permeability change in the sensitivity generating process in the coal reservoir during the in-situ coalbed methane drainage can be dynamically monitored in real time, the effective control of the coalbed methane well drainage can be implemented, and the test system has high controllability, easy installation, and safety and reliability.

Description

technical field [0001] The invention relates to the technical field of coal bed gas exploitation, in particular to a dynamic monitoring coal reservoir sensitivity and drainage control simulation test system. Background technique [0002] Affected by the tense situation of conventional oil and gas, the composition and supply form of coal as the main energy source will not change, and the large amount of gas emissions in the coal mining process will make the greenhouse effect more serious and threaten the ecological security of the whole nature. Human beings are increasingly demanding new and clean energy sources, so the mining and utilization of coal gas in coal seams as a new and clean energy source is still receiving widespread attention. [0003] my country is rich in coalbed methane (gas) resources. The development of coalbed methane and the extraction and use of gas are of great significance to alleviating the shortage of oil and gas resources in my country, reducing the...
