Field testing technology for shale gas content
摘要
Abstract
The in-house developed intelligent shale gas desorption system was improved. A temperature sensor was installed inside the desorption canister to monitor the interior temperature and eliminate the influence of gas volume expansion caused by temperature change on experimental results. The conventional desorption method was optimized by using the improved instrument. The high temperature desorption method at 90 ℃ or 110 ℃ as the second-order desorption temperature was proposed to shorten test time from 40 h to 12-25 h, which ensured the reliability of test results with the advantages of practicality and safety. Due to the influence of manual operation, the initial desorption rate would always be abnormally high. In this case, we advised the use of the desorption data 5 min after core sealing as the initial point when fitting gas loss curves.关键词
