该区位于南海南部板块、陆块的碰撞、俯冲、增生部位。作者在区域地质构造背景和区域地层对比研究的基础上 ,划分了多种类型圈闭和 5种与之有关的油气藏类型。根据盆地模拟和含油气系统的研究成果 ,作者对各种类型油气藏特征和成藏因素及其勘探前景作了分析 ,指出了与已发现油气田相类似的油气藏类型的成藏时代和有利分布区 ,可为油气勘探提供科学依据 The area is located in the southern South China Sea plate, the collision of land, subduction, hyperplastic parts. Based on the regional geological tectonic setting and regional stratigraphic correlation studies, the authors classify many types of traps and five related types of reservoirs. Based on the research results of basin modeling and petroleum system, the authors analyzed the characteristics of various types of reservoirs and their reservoir forming factors and exploration prospects, and pointed out the reservoir forming age and favorable distribution of similar reservoir types to discovered oil and gas fields Area, can provide a scientific basis for oil and gas exploration
