依据储层物性、试气、测录井等相关资料,结合岩心宏观观察与微观薄片分析,对巴喀地区八道湾组致密砂岩气藏的形成条件与控制因素进行了系统研究。研究表明:八道湾组是盖源一体、自生自储式的致密砂岩储层,其烃源条件丰富;储层的产气量随孔隙度和渗透率的增加而升高;辫状河道微相是主要的含气储层段;八道湾组储层气藏主要分布在背斜构造的构造高部位置上。
Based on the related data of reservoir properties, test gas and logging well, the formation conditions and controlling factors of the Badaowan Formation tight sandstone gas reservoir are systematically studied with the macroscopic and microcosmic analysis of cores. The results show that: the Badaowan Formation is a captive sourced, self-generating and self-storage tight sandstone reservoir with abundant hydrocarbon sources; the gas production of the reservoir increases with the increase of porosity and permeability; the braided channel microfacies are The main gas-bearing reservoir section; the Badaowan Formation reservoir gas is mainly distributed in the structural upper part of the anticline.
