摘要

卢刚臣 ,孔凡东 ,李建英 ,李振勇 ,丁学垠 .乌马营地区一种特殊的断裂组合形式 .石油地球物理勘探 ,2 0 0 1,36 (6 ) :716～ 72 2　　乌马营地区下第三系构造复杂 ,断裂纷繁杂乱 ,断层分析难度大、效果差。为了在该区寻找有潜力的勘探区域 ,本文借助剖面上滚动背斜形态来描述该区构造图上存在的平面滚动断裂系 ,从而较清楚地揭示了众多断层在平面上分布的规律性。结合地震剖面上该断裂系分布特点 ,对该区下第三系进行了构造、成藏规律的研究 ,指出平面滚动断裂系的高曲率转折部位是有利的勘探区带 ,使得该区勘探方向明朗化。经钻探证实了本项研究结论的正确性。
Eogene structure is complication and its faults are disorganization in Wumaying area. It is very difficult to analyze each fault and results is bad. In order to find exploration prospect in the area, the paper described plane rollover faulting system existing in structural map by the aid of rollover anticline pattern on profiles, so that can illustrate regularity more clearly that the faults distribute on a plane. Combining fault distribution regularity on seismic sections and study of Eogene structure and reservoir-formed regularity in the area, the article pointed out that the turning position of large curvature in plane rollover fault system is favorable exploration strip, which made exploration direction of the area more clear. The correctness of the study has been proved by drilling results.
