Research on Sedimentary Facies of Formation of Neogene in Oilfield

Abstract:

The paper studied the sedimentary system of No.1 and No.2 structure in Nanpu oil field with methods of geological, logging, seismic and chemical analysis, associated with core characteristics, sedimentary structure, profile structure and logging facies. The results demonstrate the following three points. First, Minghuazhen Formation in Nanpu field is meandering river sedimentary, and the channel subphase can be further divided into channel bottom lag deposits, beach, abandoned channel and natural levee. Second, the isopach and sedimentary face map of Minghuazhen Formation are generated based on each well's thickness of sand body and curve characteristics, and show the trend of North West and South West distribution. Third, sand body distribution can be predicted though spatial distribution of sedimentary face. And linear reservoir and Barrage-type reservoir are the two typical zones of Minghuazhen Formation.
