Abstract：The multistage of formation unconformity were formed during the evolutionary process of western slope area, south of Songliao basin, especially the unconformity in fault-to-depression transforming stage experienced stronger fold and long period of lifting erosion, which provided developing background for multistage and multi-type of slope break zones. Through early days' study and accumulation, we have some knowledge of oil-geologic condition in western slope area, especially the reservoir-genesis condition of subtle reservoir. The study considered that the distribution of slope break zone controlled internal pattern, sedimentary sub-facies and major sedimentary microfacies of the level Ⅲ sequence, and formation and distribution of overlap traps and reservoirs; the paper also considered the subtle reservoir in western slope area would become the new area of exploration and the exploration taking the overlap reservoir as a key object would bring new exploration discovery and breakthrough.
