摘要：

珠江口盆地东部可分为惠陆东沙、西江、恩平和白云等4个含油气系统。其中惠陆东沙为富含油气系统,主力生油岩在裂陷构造层底部,形成跨越储集与异地式两种成油组合,圈闭完整,具同生性,生油高峰与圈闭形成期均在早中新世晚期～中中新世,并与断裂活动较弱期相匹配,形成油气长距离侧向运移的良好条件,油气藏不是常见的环状模式,而是呈平行水流方向分布。根据凹陷的生烃差异和油气运移模式及方向分析,珠江日盆地东部惠陆东沙含油气系统南部,西江含油气系统东、南部及白云含油气系统东、中、南部较深～深水区为3个有利的油气勘探区带。

Abstract:

The east part of Pear Rive Mouth Basin contains Huilu-Dongsha, Xijiang,Enping andBaiyun petroleum systems. Among them, Huilu-Dongsha is the richest one. The primarysource rocks of the systems are in the bottom of fracture horizon. This results in intrahorizonand allochthony types of oil migration-accumulation assemblages. The traps of the system arecomplete and contemporanous. In the system,the peak period of oil generation matched withtrap forming period,especially weak faulting period. This provides favourable conditions forthe long distance lateral migration of oil and gas. The system's oil pools are distributed inzonary type paralleling with water current direction. Accoring to the differentiae of hydrocarbon generation of the basin,and the migration and accumulation model,it is suggested thatthe deep water regions in the south part of Huilu-Dongsha system,the eastern and southernparts of Xijiang system as well as the eastern,central and south parts of Baiyun oil systemare favourible regions for oil exploration.
