Stratigraphic and Sedimentary System Study of the Paleogene Series in Zhuanghai Area,Jiyang Depression
The Zhuanghai area boasts favorable oil-source conditions with low exploration intensity.Recent drilling activities in the Paleogene series have consistently yielded high oil production rates,showcasing significant potential for increased reserves.Exploration practices have confirmed diverse sedimentary types and complex provenance in the Paleogene series,emphasizing the crucial role of understanding the distribution of sedimentary systems in discovering oil and gas resources.This paper,utilizing well logging,core analysis,and seismic data,comprehensively considers factors such as structural evolution and provenance systems to elucidate the sedimentary types and distribution patterns in the Zhuanghai area's Paleogene series.
