The Oil Accumulation Law of Putaohua Oil Layer in Taidongarea, Songliao Basin

Abstract:

The research on Putaohua oil layer in Taidong,Songliao Basin using core,logging and seisimic information shows that oil is divided into belts from east to west influenced by faults striking from south to north and oil potential is getting poorer from east to west, oil is mainly distributed in the middle of Putaohua oil layer showing double peaks, and the main reservoir type is fault-lithology reservoir formd by NStrending faults and NW trending channel sandbody on the slope dipping to the southeast. According to the match type between fault and sandbody in single trap ,we draw the accumulation law that oil accumulation area is controlled by single fault-terrace belt; the high-quality reservoir is composed of underwater distributary channel and river sheet sand; vertical oil accumulation height is influenced by fault lateral sealing ability; and oil accumulation horizon is controlled by the match type between fault and sandbody.
