EVALUATION OF BURIED OIL-CONTROLLING STRUCTURE IN LOESS REGION BY REMOTE SENSING METHOD
遥感方法对黄土地区隐伏控油构造的评价

This paper presents the marks for recognizing the buried faults in loess region, and the four types of buried faults have been classified: 1. bed rock faults 2. new structure or inheritance structure 3. dyke-rock or dyke swarm 4. deep structure. Based on above classification, the regional structure pattern and the third grade structure unit, which are different from the traditional concepts, have been proposed. According to the types of oil-gas reserve theory and the structural background in study region, it is suggested that the water-resisting structure entrap oil-gas reserve as oil-controlling structure. Then the three buried faults are taken as examples to explain the features of R. S. information of water-resisting structure or water permeability structure and their forming mechanism. At last, the three oilfields have been predicted in the work region.
