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.
