TRAP TYPES AND THEIR GENESIS ANALYSES OF WAN’AN BASIN IN SOUTH CHINA SEA

摘要: 作者在分析该含油气区地质构造特征、地层划分和沉积特征的基础上,划分了压缩型、伸展型、剪切型3种构造类圈闭和重力、地层-岩性两种非构造型的圈闭,并选用南、北两条典型地震剖面模拟了典型圈闭形成过程及其与构造运动之间的演化关系,可为在该区中寻找同类型含油气圈闭和进行构造演化史的研究提供可靠依据。

Abstract: Five　types of traps, including compressional, extensional, shearing, gravitative and strata-litholoical types, were divided on studying the feature of different tectonic movements, seismic sequences and depositional property in Wan'an Basin. The author have simulatesd their evolution relationship based on two sections in the north and south of the basin respectively. Furthermore, the genesis of traps was analyzed. It will provide some evidence for studying petroleum geology in the basin.
