【摘要】 通过对涪陵地区沉积相带的展布规律、地质构造特征和已知井的钻井资料及试气情况的综合分析,发现研究区目的层大安寨段具有低孔低渗、高产气、裂缝发育的特点。采用叠后及叠前地震资料开展的裂缝型储层研究结果,进而对大安寨段进行裂缝预测。通过对比各种方法取得的实际效果,从中优选出蚂蚁追踪技术和基于叠前各向异性的裂缝检查技术,能够为该区裂缝的综合描述和寻找裂缝发育带提供有效的依据。更多还原

【Abstract】 Through a comprehensive analysis of sedimentary facies distribution,geological structure,and known well drilling data and gas test situation in Fulin region,it is found Daanzhai member of the target area is with low porosity and low permeability,high gas yield and fracture developed.By using post stack and pre stack seismic data to study fracture reservoir,and predict fracture of Daanzhai reservoir.Comparing the actual results achieved by various methods,we optimized the ant tracking technology and fracture inspection technology based on pre stack anisotropy,which can provide an effective basis for comprehensive description and searching of the fracture in the study area.更多还原
