东营凹陷王古1潜山构造特征与含油气性分析

王古1潜山是首次在东营凹陷钻探成功的深部潜山.通过对王古1潜山的构造特征、形成演化过程研究,认为王古1潜山属于内幕式的褶皱块断山,是经历了从古生代到新生代多期次挤压、拉张应力场相互叠加所发展起来的潜山,其内幕逆冲推覆构造为断层传播褶皱.在此基础上,探讨了王古1潜山的烃源岩、储集层以及油气运移通道等条件,最后,提出在该地区下一步勘探的有利区域.

Structure characteristics and reservoir-forming conditions of Wanggu 1 buried hill, Dongying sag, China

The industry oil has been found in Wanggu 1 buried hill for the first time. It has very important guide meaning on petroleum exploration in this areas. By analyzing the structure characteristics of Wanggu 1 buried hill and its formation process, this paper points out that Wanggu 1 buried hill is the inside fold-faulted hill and has underwent multiphase compresses, and stress field stacking from Paleozoic to Cenozoic and come into being. The over thrust nappe of Wanggu 1 buried hill is explained as the fault-propagation fold. Through discussing the source rock, reservoir and migration path way, the next possible favorable exploration area is put forward finally.
