摘要

川西龙门山山前的须家河组气藏为受断层和构造控制的裂缝-岩性气藏,针对这类裂缝性复杂气藏利用基于地质成因的地史时期应力场(应变)分析、沿层构造属性分析和叠前三维地震数据相干体分析等手段进行分析处理可以达到气藏裂缝发育带预测目的。实践表明,虽然在山前复杂构造带利用地震资料研究储层裂缝及其发育带确实有较大的难度,但联合运用基于应力场和断层与构造属性的裂缝综合预测方法,仍然在龙门山前须家河组气藏的应用研究中取得到令人满意的地质效果。
At present,the fracture type oil-gas fields become the main exploration target.The fracture-lithology gas pool of the Xujiahe Formation of the DY structures in the front of Longmenshan of west Sichuan was controlled by faults and other structures.Based on the analyses of geological characteristics,stress and strain fields,structural attribution of reservoirs and 3 dimensional seismic data the development of fractures in the gas pool was predicted.It was indicated that the prediction could achieve satisfactory result if the synthetic analysis of stress field,fault and structural attribution of the fractures was employed.
