摘　　要：针对潞安矿区煤储层压力普遍偏低的情况 ,根据该矿区埋藏—热演化史和流体状态方程 ,对储层压力的变化史进行了分析计算 ,认为煤储层温度降低所引起的流体体积收缩是造成储层低压的主要原因 。Based on the fact of universally lower coal reservoir pressure in Lu′an Coal Mining Area,with the bury-thermal development history and hydr-state equation the development history of coal reservoir pressure is analyzed.It is suggested that one of reasons for lower coal reservoir pressure is fluid cubage shrink caused by coal reservoir temperature drop.The temperature drop is related to the normalization of old abnormal thermal field and tectonic uplift.
