摘要
桩海地区油源条件优越,勘探程度低,近期完钻探井在古近系均获得高产油流,展现出较大的增储潜力.勘探实践证明,古近系沉积类型多样,物源复杂,因此阐明沉积体系分布对发现油气资源至关重要.通过利用钻测井、岩心和地震资料,综合考虑构造演化、物源体系等多种因素,明确了桩海地区古近系沉积类型及分布规律.
Abstract
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.
