对沉积埋藏史、构造演化史、应力场演化史进行了研究,提出了通过计算地史时期断面所承受的正应力来研究断层封闭演化史的方法。运用该方法对崔庄地区崔6、崔7两条主要断层进行了分析。结果表明,埋藏深度不同,断面正应力的大小也不同。吴堡运动时期,两条断层为开启状态;三垛运动时期,两条断层均承受压应力,但崔6断层的封闭性优于崔7断层,即成藏期封闭性好的断层控制的断块,其油气富集程度高;反之,油气富集程度就低。
The burial history, tectonic evolution history and stress field evolution history are studied. A method to study the evolution history of fault sealing by calculating the normal stress sustained by the geologic history section is proposed. This method is used to analyze Cui6 and Cui7 two major faults in CuiZhuang area. The results show that the burial depth is different, and the normal sectional stress is also different. During the Wubao movement, the two faults were open. During the movement of the three stacks, both faults were under compressive stress. However, the sealing of the Cui 6 fault was better than the Cui 7 fault, ie, the closed fault control during the reservoir formation Block, the high degree of oil and gas enrichment; the other hand, the degree of hydrocarbon enrichment is low.
