Title: The research of paleogene sedimentary system and rules of oil-gas reservoir formation in the east subsag around beach sea of Liaohe oilfield
Abstract: the research of the rules of oil-gas reservoir formation and exploration foreground is base on the exploration of fault block reservoir and fault nose reservoir in the east Subsag around beach sea,Liaohe oilfield.We should discuss three problem: the Characteristics of sedimentary faces,the sedimentary system and the rules of oil-gas reservoir.After the research,we conclusion that the east subsag had deep-subsidence period,Expansion period and another deep-subsidence.It have nearshore subaqueous fan,fan delta,braided river delta,delta and river sedimentary faces.The type of oil-gas reservoir have fault block reservoir,fault nose reservoir,updip sandstone pinchout reservoir and so on.the sedimentary faces control the oil-gas reservoir formation.
