%0 Journal Article %T CBM Injection/Falling Off Well-Test Parameters' Optimization and Study in the Middle of Qinshui Basin, China %J - %D 2018 %R http://dx.doi.org/10.3968/10106 %X As one effective mean of obtaining CBM parameters, injection/falling off well-test also has abnormal results. This paper studies process parameters¡¯ optimization such as injecting pressure, injecting volume, shut-in time and reservoir closure pressure, which will insure test procedure and results¡¯ reliability. In order to avoid ambiguity of well-test results it studies fluid and reservoir parameters¡¯ impacts on well-test interpretation results, and determines the range of parameters¡¯ value such as compression co-efficient, fluid viscosity and so on. The results prove that injection parameters¡¯ design affects field test success, determines whether test data truly reflect reservoir information or not, and its values may affect the accuracy of well-test interpretation. This paper¡¯s study will play an important role on solving injection/falling off well-test abnormal problems. %K CBM reservoir %K Injection/falling off well-test %K Process parameters %K Reservoir closure pressure %K Well-test interpretation %U http://cscanada.net/index.php/aped/article/view/10106
