鄂尔多斯盆地西缘横山堡区块断裂构造特征及其控藏模式
Characteristics of Fault and Accumulation Models in Hengshanbu Block on the West Edge of Ordos Basin
摘要
Abstract
In Hengshanbu block on the west edge of Ordos Basin, a series of NNE thrust faults have been developed, which are roughly evenly spaced and parallel. It is shown that the faults distributed in east-west zoning on the plane, which can be divided into three sets of fault systems, including the inversion of faulted anticlinal structures in the west and flower structures in the centre, and the inversion of thrust faults in the east. In profile, many kinds of structural styles, such as anticlinal, flower structure, controlled by thrust fault, have been developed. It is concluded that fault is the main controlling factor for oil and gas accumulation by analyzing the reservoir characteristics of Liujiazhuang gas field and Shengli gas fields around Hengshanbu block. Based on the combination of different faults, two types of accumulation models, namely inversion structure and flower structure, are proposed.关键词
