摘要(Abstract):
通过对断层侧向封闭机理及影响因素的分析,提出了一种根据断移地层岩性及断距预测断裂填充物中泥质含量的计算方法。根据断裂带岩性与断层运移盘岩性之间的差异,提出了一种断层侧向封闭性的预测方法,并将其应用于济阳坳陷车古20潜山主要断裂侧向封闭性的研究中,其结果与该区实际地质条件十分吻合,证明了该方法的可行性。
Through analyzing the lateral sealing mechanism of fault and its influencing factors,this paper puts forward a method predicting the percentage of mudstone in filling material of faulted zone according to the lithology of faulted strata and fault throw.According to the difference between the lithology of faulted zone and the lithology of the faulted block reservoir,this paper puts forward a method evaluating the lateral sealing of fault. It was applied in studying the lateral sealing of the main faults in Chegu 20 buried hill of Jiyang Depression.The research results are identical to actual geological conditions,it proves that the method is practical to evaluate the lateral sealing of fault.
