摘要
广西百色盆地是在海相中三叠统基底上发育起来的第三纪陆相断陷盆地。对盆地油气系统要素进行了深入分析,用“四图一表”表示。研究结果表明,盆地内存在那读组和百岗组2套烃源岩,有较好的储集层和3套盖层以及较厚的上覆岩层,生储盖组合良好,但盆地成型后的构造作用使其保存条件遭到了极大破坏,因此勘探实践揭示的油气情况并不十分理想。
The Baise Basin in Guangxi Province is a Tertiary fault-depressed hydrocarbon basin of continental facies developed in the Triassic basal of marine facies. The essential elements of petroleum system （from source to trap） are thoroughly studied, and then ＇four charts and one table＇ are illustrated to express the basin explicitly so as to help further hydrocarbon exploration and development. There are two sets of source rocks, namely the Nadu Formation and the Baigang Formation, with fine reservoir and caprocks, forming good assemblage of generation,reservation and capsulation, yet the tectonic activities subsequently reconstructed the basin preservation greatly, therefore hydrocarbon exploration in the basin is far from satisfaction.
