摘要

长昌凹陷是琼东南盆地东部具有一定勘探潜力的地区,新近系三亚组为一套厚度巨大的海相砂泥岩地层,可分为2段,均是重要的储层。综合应用测井、重矿物、古生物、地震剖面等资料对物源进行对比与分析,在长昌凹陷三亚组共识别出5种主要的沉积体系:滨海、浅海、三角洲、半深海、海底扇。琼东南盆地深水区长昌凹陷在三亚组沉积期是中国南海北部一个大型的坳陷型海盆,在古地貌、物源输入等2个地质因素的共同作用下形成大型海底扇,厚度大,物性好,沿中央坳陷带轴向展布。三亚组大面积海底扇的发育形成了长昌凹陷最大规模的优质储层,具有成藏的独特优势,其与构造叠合所形成的构造-岩性油气藏是琼东南盆地深水区油气勘探获得突破最现实的领域。

Abstract

The Changchang Sag is an important potential hydrocarbon exploration area in the eastern Qiongdongnan Basin. The Neogene Sanya Formation is a set of huge marine sandstone and mudstone stratum,and it can be divided into two members,all of which are important reservoirs. Based on data of logging,heavy minerals,paleontology and seismic sections,the provenance and the sedimentary system of Sanya Formation were analyzed. There are five kinds of sedimentary systems,including coastal,neritic,deltaic,bathyal and submarine fan system. Changchang Sag is a large marine depression in northern South China Sea during the sedimentary period of Sanya Formation. Under the coaction of paleogeomorphology and provenance input,a large submarine fan was formed,which is characterized by great thickness,good physical properties and basin axial distribution. The the largest high-quality sandstone in the huge submarine fan has unique advantage of reservoir accumulation in Changchang Sag. The structural-lithologic reservoirs are the most realistic prospects for deepwater hydrocarbon exploration in Qiongdongnan Basin,which is formed by its superposition with structure.
