伊通地堑莫里青地区双一段沉积相及与油气关系
SEDIMENTARY FACIESES AND THEIR RELATIONS WITH OIL AND GAS IN SHUANG NO.1 MEMBER OF MOLIQING AREA OF YITONG GRABEN
摘要
Abstract
Guided by the theories of high-resolution sequence stratigraphy and sedimentology, Palaeogene Shuang No. 1 Member in Moliqing area is divided into a middle cycle; the rising hemicycles of the member are further classified into a short cycle and two rising hemicycles with the help of the geologic, logging and seismic data. The descending and rising hemicycles of the middle cycle are corresponding to No. I and No. II sand groups; and the short cycle inside the rising cycle is corresponding to three sub-layers of No. II sand group. Based on the isochronous stratigraphy framework, three types of sedimentary facies as fan delta, sublacustrine fan and lake facies are discriminated in Shuang No. 1 Member; The developments of the sublacustrine fan and fan delta deposits possess the trend of continuous shrink from the sedimentary period of No. II and No. I sand group in Shuang No. 1 Member. The underwater distributary channel micro-facies of fan delta and braided channel micro-facies of sublacustrine fan are favorable facies belts for oil and gas accumulation.关键词
