摘要
从基础石油地质条件出发,结合珠江口盆地西部实际成藏特征,以优质供烃单元和油气运聚条件为领域突破的核心要素,通过梳理优质供烃单元的沟源断裂发育区与欠发育区、油气运移距离远近、纵向成藏层系分布三者之间的关系,对琼海凸起裙边带古近系的成藏条件进行了深入研究。提出琼海凸起裙边带古近系岩性地层圈闭具有优越的成藏条件,该区域是珠江口盆地西部下一步极有可能取得油气勘探突破的重点地区。
Based on the basic petroleum geological conditions,combined with the actual accumulation characteris⁃tics of the western Pearl River Mouth Basin,and taking the high-quality hydrocarbon supply unit and oil and gas mi⁃gration and accumulation conditions as the core elements of the breakthrough in the field,by combing the relation⁃ship between the gully source fault development area and the undeveloped area of the high-quality hydrocarbon sup⁃ply unit,the distance of oil and gas migration,and the distribution of vertical accumulation layers,the accumulation conditions of the Paleogene in the skirt belt of Qionghai uplift were studied in depth.It is proposed that the Paleo⁃gene lithologic stratigraphic traps in the skirt zone of Qionghai uplift have superior reservoir forming conditions.This area is the key area in the western part of the Pearl River Mouth Basin that is very likely to make breakthroughs in oil and gas exploration in the next step.
