摘要
冷家堡油田沙三段为一套陡坡近岸水下扇沉积。储层平面和层内非均质程度严重,具有4类20种物性韵律模式。低渗细喉不均匀型和低渗透微细喉不均匀型为主要孔隙结构类型。泥质含量、粘土矿物产状分布及沉积成岩后生作用是影响储层物性的重要因素。
The shahejie 3 member of Lenjiapu Oil Field, Liaohe is subaqueous fan deposition of abrupt slope naer shore. Heterogeneous degrees of surface and within in reservoirs are high. There are 4 types (subdivided into 20 Kinds) models of rhythm. Low-permeable differential fine throsts are main kinds of porous strucures. Shale contant, minerals distribution of clay, sedimentation and cpidiagenesis arc important factors of influencing reserviors properties.
