中央凸起一直被视为勘探禁区,关于其形成与演化一直认识不清,虽然不能直接为勘探部署提供依据,但它是勘探目标评价的前期研究、基础研究,对研究潜山裂缝发育期次、成藏期次、地层结构和内幕构造研究及输导体系都是大有裨益的。本文通过对中央凸起构造带构造演化分析入手,对基底地质结构、潜山地层岩性特征、分布特点以及潜山深层油气成藏条件进行了探讨性研究。
The central bulge has been regarded as a forbidden zone for exploration and its formation and evolution have not been fully understood. Although it can not directly provide a basis for exploration and deployment, it is a preliminary study and basic research on the evaluation of exploration targets. , Accumulation period, stratum structure and insider structure research and transmission system are of great benefit. Based on the tectonic evolution analysis of the raised structure belt in the central area, the geological characteristics of the basement, the lithologic characteristics of buried hill formations, the distribution characteristics and the hydrocarbon accumulation conditions in deep buried hills are discussed.
