摘要
前人对万安、曾母、文莱-沙巴盆地的油气地质条件开展大量研究,对盆地之间的油气地质条件差异性研究较少.以前人大量研究成果为基础,综合利用钻井、地震、油气测试等资料,对中国南海南部万安、曾母、文莱-沙巴三大盆地的主要油气地质条件开展差异性分析.研究认为:3个盆地新生代均经历了两期构造演化阶段,主要发育海陆过渡相和海相沉积环境;3个时期(渐新世、中新世和上新世)发育三角洲煤系和陆源海相两类烃源岩,主力烃源岩发育时期从西往东逐渐变新;发育碎屑砂岩和碳酸盐岩两类储层,呈现"近岸砂、远岸礁"分布特征,储层发育时期从西往东逐渐变新;发育近岸的自生自储型和远岸的下生上储型2种生储组合.
Many studies have been carried out on the hydrocarbon geologic conditions of Wan＇an,Zengmu and Brunei-Sabah basins.However,there are few studies on the difference of hydrocarbon geologic conditions among basins.Based on a lot of previous research results,drilling,seismic data and oil and gas testing data were comprehensively used to analyse the main difference of hydrocarbon geology in the Wan＇an,Zengmu and Brunei-Sabah basins in southern South China Sea.The study shows that the Cenozoic of the three basins all developed two tectonic stages,mainly developing marine-land transitional facies and marine depositional environment.Three periods（Oligocene,Miocene and Pliocene）developed two types of source rocks,i.e.the coal measures and terrigenous marine facies,the period of major source rock is gradually new from west to east.Developed two types of reservoirs,i.e.clastic sandstone and carbonate rock,reservoirs distribution may be characterized by near shore sand and distant shore reef,the reservoirs period is gradually new from west to east.There are two combination of source rock and reservoris,i.e.the distant shore self-generation and self-reservoiring and the near shore lower-generation and upper-reservoiring.
