Abstract: In dealing briefly with the geological development of the Shan-Gan-Ning district, the paper lays particular emphasis on the geological aspects of the erosional landform at the close of the Indo-Chinese stage when the topographic relief was greater than 300 meters and a big branching river system was developed. Such a landform left a notable impact on the sedimentary overburden of early Jurassic. It restricted the distribution of the sandstone facies zone and the river system at the bottom of Jurassic and resulted in the occurrence of many compaction structures or buried-hill structural group. And it is this kind of buried-hill structures coupled with favourable lithologic conditions that determine the oil and gas field distribution in the Jurassic of this area and may serve as the direction in the search of oil. From the point of view of paleogeomorphology, the buried-hill compaction structures in the hilly land along the river banks in front of the mountainous region are the loci for the accumulation of oil and gas.

摘要： 在地质历史中,各种被埋藏的古地形往往与油气的分布密切有关,因此早已引起了人们的注意。在北美、北非和西西伯利亚等世界许多含油气区中,关于油气田的分布与古地貌发育的成因联系,曾有过报导。我国华北地区前第三系断块型古潜山油气田也已经作过比较深入的研究。
