摘要:

莺歌海盆地东方区黄流组一段发育大型海底扇。通过构造、物源、沉积分析,源自昆嵩隆起的蓝江优质物源,在区域构造事件发生之际,穿过构造转换带与非经典坡折带,在东方区形成大型海底扇。有孔虫较丰富,以浮游类占优势,指示海底扇形成于外陆架环境。东方区海底扇面积大,多期砂体相互叠置,储层物性好,显示该地区具有良好的油气勘探前景。

Abstract:

A large submarine fan is developed in the first member of Huangliu Formation in Dongfang area, Yinggehai Basin. Tectonic, provenance, and sedimentary analysis show that during regional tectonic events, high-quality source materials derived from the ancient Lam River in Kontum uplift were transported through the structural transfer zone and non-classical slope break zone, resulting in the formation of a large submarine fan in Dongfang area. Abundance of foraminifera dominated by planktonic type in the strata indicates that the submarine fan was formed in a paleoenvironment of outer continental shelf. The submarine fan covers a large area with multi-stage superimposed sand bodies and good physical property, showing great prospects for oil and gas exploration.

Key words: Yinggehai Basin, non-classical slope break zone, submarine fan, very fine-fine grain, high temperature and overpressure
