摘要:

以前人研究成果为基础,结合构造演化、沉积充填特征及地球化学指标分析,对南海南部3个主要盆地进行了油气分布规律及主控因素研究。结果表明,万安盆地和曾母盆地发育渐新统—下中新统煤系和陆源海相2类主力烃源岩,干酪根类型为Ⅱ—Ⅲ型;文莱—沙巴盆地发育中中新统—上新统煤系烃源岩,干酪根类型为Ⅱ2—Ⅲ型。万安盆地油气富集于中新统储层,平面上具有“西油东气”的分布特征;曾母盆地油气富集于渐新统—中新统储层,具有“下油上气”分布特征,平面上具有“南油北气”的分布格局;文莱沙巴盆地油气富集于中中新统—上新统砂岩储层,近岸浅水区是油气主要富集区。3个盆地受古南海消亡和新南海扩张的控制,主力烃源岩发育时期沉积环境各异,后期盆地内成熟度的差异性控制油气分布的区带性,构造运动在各盆地的响应机制导致油气成藏具有明显规律性。

Abstract:

The study about hydrocarbon accumulation and distribution controlling factors of three major basins in mid-southern South China Sea has been carried out,not only based on predecessors’ research but also combined with tectonic evolution,sedimentary filling and geochemical data analysis.In Wan’an Basin and Zengmu Basin,there are two types of major hydrocarbon source rocks,coal measures and terrigenous marine facies,both in Oligocene-Lower Miocene strata.Kerogen types are type Ⅱ-Ⅲ.While in the Brunei-Sabah Basin,the hydrocarbon source rock is coal measures in Mid Miocene-Pliocene,with kerogen type of Ⅱ2 -Ⅱ.Hydrocarbon accumulation in Wan’an Basin are mainly in the Lower-Upper Miocene,and the horizontal distribution is featured as oil in the west and gas in the east.In Zengmu Basin,hydrocarbon accumulated more in Oligocene-Miocene Formations with distribution characteristics as oil in the upper and southern parts and gas in the lower and northern parts.And in Brunei-Sabah Basin,hydrocarbon accumulation is enriched in Mid Miocene and Pliocene,the main oil and gas favorable zone is the offshore coastal area.All these three basins are controlled by evolution of the South China Sea.During the development period of these major hydrocarbon source rocks,the sedimentary environments varied in these basins.The diversity of maturity in different basins controlled the hydrocarbon distribution directly.And the different responding mechanisms to tectonic movements of these basins result in the obvious diversity and regularity of hydrocarbon accumulation.
