多年的勘探实践证实,文昌A凹陷发育文昌组和恩平组2套主要的烃源岩,油气资源丰富,具有中部气成藏,周边油成藏的特征。认为文昌A凹陷中央隆起带、珠三南断裂东段下降盘和北部斜坡带成藏条件优越,是珠江口盆地西部近期油气勘探的重要领域。

After many years exploration, it’s proved that source rocks of Wenchang and Enping formation are two sets of important source rocks developed in Wenchang A sag, where there is rich hydrocarbon resource with the characteristics of gas being accumulated in the center and oil being accumulated in the margin. The study shows that the play condition is excellent in the central uplift, downthrown block of eastern Zhu Ⅲ south fault, and northern slope of Wenchang A sag, and they are important fields for hydrocarbe.
