[0003] However, the accuracy of the residual gas content measured by the above-mentioned method is low. When using the ball milling method to measure the residual gas content, the ball milling time has a greater impact on the result of the measurement. The longer the ball milling time, the more accurate the measurement result; the above-mentioned residual gas content determination The method takes too long, and the desorption of the sample for a long time is reversible under a certain temperature and pressure. The sample changes from block to powder, which will increase the adsorption area; and it is difficult to collect by the above method, and the residual gas content is small , the traditional collection method is not applicable, and the collected gas composition has errors

Description
technical field [0001] The invention relates to the technical field of measuring residual gas in samples of tight oil and gas reservoirs, in particular to a residual gas measuring device and method. Background technique [0002] At present, the determination of the residual gas content of rock samples is usually carried out by using a ball mill to mechanically pulverize the rock samples and then collect the residual gas. After the temperature of the shale rock sample returns to the reservoir temperature, the gas desorption is repeated at specified time intervals until the average daily gas desorption amount is less than or equal to 10 cm 3 / d, and then measure the residual gas volume. [0003] However, the accuracy of the residual gas content measured by the above-mentioned method is low. When using the ball milling method to measure the residual gas content, the ball milling time has a greater impact on the result of the measurement. The longer the ball milling time, the m...
