川中地区须家河组气藏水平井开发效果浅析

Analysis of gas pool development effectiveness by horizontal well in block Xujia River

通过须家河低渗气藏开发情况的研究,分析了须家河低渗气藏水平井开发效果的特点。实践表明,采取欠平衡/气体钻井与水平井钻井相结合、保护和暴露储层并重的开发模式,较适应该气藏的开采;同时",低成本水平井+加砂压裂"可望成为有效提高须家河开发效益的开发技术。

Based on the study on development behavior of low-permeability oil reservoirs in Block Xujia River,this paper analyzes the development effectiveness of low-permeability gas reservoir by horizontal well.The practice demonstrates that such development pattern as underbalanced gas drilling combining with horizontal well drilling as well as laying equal stress on preservation and produc-tion of reservoir is relatively applicable for such gas pool.And the pattern of ＂low cost horizontal ＋ sand fracturing＂ is expected to be beneficial to develop Block Xujia River.
