摘要

摘要: 为了分析断裂对油气宏观分布规律的控制作用，寻找有勘探潜力的油气富集带，文中以地质力学理论为指导，对南堡凹陷断裂组合应力特征、断裂转折及成因进行解析，并结合砂体分布和古今构造应力场分布特征，对南堡凹陷东营组油气分布规律和有利勘探区带做了研究。结果表明：断裂转折部位对油气分布有着控制作用，东营组已探明的油气主要在帚状断裂系、入字形断裂系、交织式断裂系转折轴部高曲率附近呈环带状分布；断裂转折凹面一侧控油性明显，从宏观上来看，油气具有沿沉积相带由细到粗的构造脊高点以及弧形断裂转折凹面一侧的选择性运移的特征，断裂转折轴部高曲率高孔、高渗域与高孔、高渗砂体沉积相带的有利对置决定了油气的主流向；综合研究指出，南堡凹陷北堡构造带是今后优势勘探的首要区带，其次是南堡构造带和南堡4号蛤坨构造带南部。

Abstract: In order to find out the control effects of faults on the macroscopic distribution of oil and gas and look for the oil and gas accumulation zones with exploration potential, taking the geomechanics theory as a guide, the combined stress characteristics of faults, the fault deflecting and the causes in the Nanpu Depression are analyzed, and the oil and gas distribution law and favorable exploration zones in Dongying formation of the Nanpu Depression are studied combined with the characteristics of sand body distribution and ancient and modern tectonic stress field distribution. The results show that the fault deflecting controls the distribution of oil and gas, and the proven oil and gas in Dongying formation mainly shows a circular band distribution near the high curvature of the deflecting shaft of the broom-shaped fault system, the λ-type fault system and the interlaced-type fault system. The oil-controlling property on the concave side of the fault deflecting is obvious. Macroscopically, the oil and gas has the characteristics of selective migration along the sedimentary facies belt from fine to thick tectonic ridge highs and on the concave side of arc fault deflecting. The main direction of the oil and gas is determined by the favorable alignment of high curvature and high porosity, high permeability domain and high porosity, and high permeability sand body sedimentary facies zone in the fault deflecting shaft. The comprehensive study indicates that the Beibu structural belt in the Nanpu Depression is the primary zone for superior exploration in the future, followed by the Nanpu structural belt and the south of the Nanpu No.4 Getuo structural belt.
