摘　　要：三叠系长8油层组是富县油田D区的主要油气勘探目的层,其孔隙度介于5%~12%,渗透率普遍低于0.5×10^(-3)μm ^(2),属致密砂岩储层。针对长8油层的油藏有效储层物性作了研究,采用经验统计法、含油产状法、测试法、压汞参数法和最小孔喉半径法确定了其物性下限。Triassic Chang 8 oil formation is the main oil and gas exploration target in D block of Fuxian Oilfield,with porosity ranging from 5%to 12%and permeability generally lower than 0.5×10^(-3)μm^( 2),which is a tight sandstone reservoir.The physical properties of effective reservoirs in Chang 8 reservoir are studied.The lower limits of physical properties are determined of permeability by experience statistical method,oil occurrence method,testing method,mercury injection parameter method and minimum flowing pore throat radius method.
