The Effects of Reservoir Temperature on Carbon Dioxide (CO2) and Nitrogen (N2) Gas Sorption in Enhanced Coal Bed Methane (ECBM)
最近，提高煤层气采收率（ECBM）已经成为许多研究人员特别是与能源行业相关的人的兴趣所在。多年来，这种方法的实施已经能够改造煤层，并能够释放出更多的煤层中的产气潜力。许多研究调查可能影响二氧化碳（CO2）和氮气（N2）注入到煤层中的效率的几个因素，以更好地了解这种方法。
这份报告的研究趋势之一是了解温度对不同储层CO2和N2与甲烷（CH4）气体吸附行为的影响，因为吸附是一个可以被系统的物理变化轻易改变的物理过程。为了回答这个问题，这份报告将介绍在不同储层温度下CO2和N2置换煤层中CH4的效率的储层模拟研究。
为了实现研究的目标，该研究将涉及使用CMG的GEM储层模拟器在不同煤层储层温度下进行ECBM生产的储层模拟。报告的结果是比较了不同气体在不同储层温度下的最大吸附能力、吸附速率和ECBM的驱替前沿形状。
Abstract：
Recently, the enhanced coal bed methane (ECBM) production has become the interest of many researchers especially for those who are related to the industry of energy. Over the years, the implementation of this method has been able to stimulate the production of coal seams and able to unlock the potential of gaining the more hydrocarbon gas from the coal bed body. Many studies been done in relation to investigate on few factors that may affect the efficiency of the carbon dioxide (CO2) and nitrogen (N2) gases injection into the coal seams for better understanding on the method. One of the trends of study which is becoming the backbone this report is to understand on how does the temperature effects on the sorption behavior of CO2 and N2 with methane (CH4) gas at different reservoir temperatures, as sorption is a physical process which can be easily altered by the physical changes of the system. To answer this question, this report will present on the reservoir simulation study on the efficiency of CO2 and N2 to displace CH4 in the coal seam at different reservoir temperatures. In order to accomplish the objectives of the study, the study will be involving reservoir simulation on the production of ECBM at different coal bed reservoir temperature by using CMG’s GEM reservoir simulator. The report resulted in the comparison of the maximum adsorption capacity, rate of adsorption and the flood front shape of the ECBM of different gases at different reservoir temperature.
