Abstract: 基于页岩气井线性非稳态流动特点,运用双重孔隙线性瞬态流典型曲线分析Eagle Ford页岩气藏一口多级压裂水平井产量数据,并进行储量评价.根据产量与时间双对数曲线关系,将该气井生产分为表皮效应、线性流动、边界效应3个流动阶段;运用基质线性流动模型计算该气藏基质渗透率,利用数值模型对计算结果进行验证;根据边界效应时间点求取该井体积压裂范围游离气储量,在此基础上进行产能预测,并研究吸附气解吸对气井产量的影响.结果表明:该井体积压裂范围游离气储量与裂缝模拟结果符合度超过85%;解吸气对页岩气井产量贡献取决于平均地层压力与吸附曲线形态;解吸气对该页岩气藏开发早中期的影响可忽略,对开发后期产量的影响很大,气体解吸能增加总采出量30%以上.
