摘要(Abstract)：

为了快速准确模拟页岩气储层开发过程中的动用情况,利用高精度波前快速推进法对波前运移程函方程进行求解,通过复合线性流模型对多级压裂水平井模型中的气体流态进行分区,实现飞行时间与真实时间的换算,得到储层动用随时间变化示意图及储层动用范围与时间的定量关系.对比波前快速推进法与高精度波前快速推进法的计算结果,发现在相同时间内,利用高精度波前快速推进法计算时储层动用范围更大.在裂缝总长相等的情况下,通过对比不同裂缝形态下的储层动用发现,在裂缝间的压力达到连通前,储层动用程度与裂缝形态无关;当裂缝之间压力连通后,储层动用与裂缝形态密切相关.

关键词(KeyWords)：页岩气;高精度波前快速推进法;储层动用;波前运移;裂缝形态
