东濮凹陷断裂系统构造格局与油气聚集

依据实际资料，采用地震与地质相结合的方法，通过拼接并系统解释全区地震大剖面，从整体上把握住了东濮凹陷的断裂构造特征及其变化。分析研究了主要断裂的组合展布及其发育特征，提出了东濮凹陷断裂系统和断裂发育期次的概念，认为东濮凹陷存在6个期次、4个级别的断裂，不同期次、不同级别的断裂有序发育，并多呈NE、NNE向雁列方式展布。进行了二、三级构造的系统划分和构造格局分析，进而分析了断裂构造与油气聚集的关系，指出了东濮凹陷潜在有利的勘探方向。

The Fault System and Structure Framework in Dongpu Depression and Its Petroleum Accumulation

On the basis of actural information,the paper researches the whole fault structure features and its variation in Dongpu Depression by the comprehensive method of seismic and geology. It analyses the combination,arrange and development of the main faults and gives the concepts of fault system andfault phases. There are six stages and four classes of the faults in the depression. The faults of differentstages and different classes had developed in sequence and most apeared in echelon array styles. The secondand third class structure units are divided and the structure framework is analysed. At last the paper givesthe relationship between fault structure and petroleum accumulation, points out the potentia1 explorationarea for oil and gas.
