TYPES OF LOWER TERTIARY SEDIMENTARY SYSTEM IN LINQING DEPRESSION AND AN ANALYSIS OF THEIR FORMATION

By an integration of geological, well logging, seismic data and in-house analysis data, this paper deals, in detail, the types and the distribution of the Lower Tertiary sedimentery systemsin Linqing depression and their controlling factors in their formation. 7 types of main sedimentary systems were developed.The rise and fall of the water level in the lake controlledthe type of the systems and their distribution. The formation was related to the factonics andpaleo-climate, in turn, innermajor oil source sags and their surrondings, stratigraphic andstructural-stratigraphic traps between S, and S. formations are oil and gas accumulated areas.
