    摘要:

    通过针对松辽盆地北部西斜坡区目前已经发现的典型油气藏进行解剖分析,发现区内主要发育岩性透镜体油气藏、岩性上倾尖灭油气藏、背斜油气藏、断层遮挡油气藏、构造(背斜)-岩性油气藏、构造(断层)-岩性油气藏及不整合遮挡油气藏等7种类型的油气藏。受构造、砂体及不整合面的发育和分布控制,各类油气藏在纵向上和平面上的分布各具规律性。结合区内各类圈闭的分布情况,对区内油气藏类型的分布进行预测认为,富拉尔基-江桥-平洋地区一带萨零、一油层、泰康隆起带东南部和富拉尔基地区萨二、三油层应以寻找岩性主控油气藏为主;而泰康隆起带中部及其西南边界附近则应是构造主控油气藏发育区;地层不整合油气藏发育区主要分布在泰康隆起带中部周边的高台子油层内。

    Abstract:

    Through typical reservoirs dissection in Western Slope of the northern Songliao Basin, it has been found that there are seven reservoirs types in this area, such as sand lens reservoir, up dip pinchout reservoir, anticlinal reservoir, fault screened reservoir, structure(anticline)-lithology reservoir, structure(fault)―lithology reservoir and unconformity screened reservoir and so on. Controlled by the development and distribution of structure, sand-body and unconformity, every kind of reservoirs has its regularities in vertical and plane. Combining with the distribution of all kinds of traps in this area, it predict that lithology-controlled reservoirs can be found in the Sa0 1 oil layers of the area Fulaerji-Jiangqiao-Pingyang and Sa2 3 oil layers in the southeast of Taikang uplift zone and Fulaerji, structure-controlled reservoirs can be found in the middle and hereabout of southwest boundary of Taikang uplift zone, and stratigraphic unconformity reservoirs are mainly developed in the peripheral Gaotaizi oil layers in the middle of Taikang uplift zone.
