摘要

雷东凹陷区处于稳定、分割、封闭且具较高地温的构造-地质环境中,具有较好的生、储、圈、盖等油气地质条件,有利于油气的生成、聚集和保存,油气资源潜力尚可,总生烃量为*-**×108t,聚集量为****×104t.具有远景较佳、可供钻探的圈闭构造,圈闭油气聚集量为***×104t.同时,该区离岸近、水浅、海底平坦,具有优良的工程地质条件和便利的油气勘探开发环境,值得进一步开展油气勘探工作。

Abstract

Leidong depression is situated in the stable, isolated, close and high geothermal geological setting, with fairly good source rocks, reservoirs, traps and cap rocks. The hydrocarbon was in favor of generation, gathering and preservation. The total hydrocarbon producted is *-**×108t, the total gathering is ****×104t. In addition, the exploration and development condition is favorable due to it is near shore, with shallow and smooth bottom. So, the oil and gas exploration is worth making progress in this area.
