摘要
为了更好地评价涪陵地区页岩气保存条件,明确可量化的保存条件构造指标。根据地层褶皱变形、出露和隆升剥蚀情况、埋深、裂缝及断裂发育特征等资料,厘清页岩气保存的关键制约因素,构建涪陵地区剥蚀强度、倾角大小,变形指数、破裂程度等五项可量化的页岩气保存条件指标参数体系,指出该区页岩气有利勘探开发目标,有效指导涪陵页岩气的高效开发。
To better evaluate shale gas preservation conditions in the Fuling region,quantifiable preservation condition structural indexes were identified.Based on data such as strata folding deformation,exposure and uplift erosion,burial depth,and characteristics of fractures and faults,key constraints on shale gas preservation were clarified.A system of five quantifiable shale gas preservation condition index parameters,including erosion intensity,dip angle,deformation index,and fracture intensity,was established.It was concluded that the Fuling Area is a favorable target for shale gas exploration and development,providing effective guidance for the efficient development of Fuling shale gas.
