CHARACTERISTICS AND EFFECTING FACTORS OF ADSORPTION TIME OF COALBED GAS RESERVOIR
煤储层吸附时间特征及影响因素

The adsorption time as gas evaluating parameter, being obtained in processing of coalbed gas measurement, is the quantitative index for evaluating gas desorption rate. The parameter is important for coalbed gas reservoir simulation and as a sensible index to control initial and long period gas producing rate of coalbed well. The purpose of this paper is to discuss the characteristics and affecting factors of adsorption time and preset some new understanding for this parameter application, based on conducted gas measurements for some coalbed gas wells in China.
