鄂尔多斯盆地西缘麻黄山地区中生界具有良好的油气勘探潜力。在对麻黄山地区构造、岩心和测井分析的前提下，探讨了不同构造带的油气分布规律、成藏过程以及油气分布的主要控制因素，认为在构造稳定带主要发育岩性、岩性-构造油气藏，而在断裂带主要发育断块、断鼻油气藏；油气分布纵向上跨度大，为上油下水，具有统一的油水界面，平面上主要分布在构造部位高、砂体发育的背斜或断背斜轴部；油气分布主要受沉积相、成岩作用和构造控制。纵向上胶结作用弱、溶蚀作用强的砂体为油气的主要富集场所，平面上处于构造高部位、水动力强的分流河道与河道砂体为油气的主要富集部位。

The Mesozoic in Mahuangshan area has a fine hydrocarbon exploration potential in the western margin of Ordos Basin. Based on the analysis of regional structure, core observation and logging, the hydrocarbon distribution, pool forming process and the main controlling factors in different tectonic zones are discussed. It is suspected that lithologic and lithologic-structural reservoirs mainly developed in the structurally stable zones, while fault block and fault-nose reservoirs mainly developed in faulted zones. Oil and gas distribution has a large vertical span with oil on the top and water at the bottom. Oil and gas in the plane mainly distributed in the high structural area or in the axial region of fault anticline, and are mainly controlled by sedimentary facies, diagenesis and tectonic control. The sand of weak cementation and strong dissolution is hydrocarbon-rich site in vertical direction, and so is the sand in distributary channel with strong hydrodynamic in high structural area in the plane.
