鄂尔多斯盆地下寺湾地区延长组长7段页岩储层特征及评价
Characteristics and Evaluation of Shale Reservoir in Chang 7 Member of Yanchang Formation,Xiashiwan Area,Ordos Basin
摘要
Abstract
Based on the analysis of shale distribution,shale buried depth&thickness,micro structure,organic mat-ter abundance,thermal evolution of organic matter,degree of porosity,permeability and micro cracks accumulation conditions,it is concluded that member 7 shale of the mesozoic Yanchang Formation is with shale gas accumulation conditions.The key geological evaluation parameters of shale gas exploration of this district include shale buried depth and thickness,organic carbon content,maturity,micro fractures and abnormal display of gas measurement, etc.According to the conditions of shale gas reservoir formation and the distribution of abnormal gas logging in the exploration process,it is predicted that Chang 7 section in the study area is the shale gas accumulation area,which can provides geological basis for subsequent shale gas dessert identification.关键词
