准噶尔盆地莫北油田莫116井区三工河组储层特征研究
|
摘要
根据莫116井区取心井资料、铸体薄片和扫描电镜等观察,结合综合录井资料及地震资料分析研究,对莫116井区三工河组岩石学特征、储层物性、孔隙类型及孔隙结构特征进行了研究。研究发现,莫116井区三工河组岩性主要为长石质岩屑砂岩,孔隙度类型主要以剩余粒间孔和原生粒间孔为主;J_1s_(2/2)较J_1s_(1/2)物性好,孔隙度和渗透率相关性较好;J_1s_(1/2)为小孔细喉道的较差储层,J1s为中孔中细喉道的中等储层。
According to the coring data,the casting thin sections and scanning electron microscope observation in Wellblock M0116,combined with comprehensive mud logging data and seismic data analysis.Characteristics of petrology,reservoir physical properties,pore types and pore structure characteristics of Sangonghe Formation of Well Block Mo116.The lithology is mainly feldspar lithic sandstone,the physical properties,porosity and permeability of J_1 s_2~2 are better than J_1 S_2~2.Primary porosity types to residual inlergranular pore is dominated,then is the primary intergranular pores.J_1 s_2~2 reservoir is small fine throat poor reservoir,J_1 s_2~2 reservoir is middle-thin throats medium reservoir.
