【Abstract】 According to the fundamental geologic characteristics of various hydrocarbon bearing structures within the peripheral areas of Qingshui depression, 3D seismic fine interpretation, formation prediction and the other novel methods are utilized extensively for progressive exploration research so as to find new oil bearing blocks and formation system and realize the breakthrough of progressive exploration in mature area. Results demonstrate that breakthrough has been seen with many high yield condensate oil & gas reservoirs found in Shuangtaizi central structural zone, which further substantiates shape of Yushutai drape anticline and favorable traps along its flanks substantiated, and Mesozoic buried hill reservoirs and a number of Tertiary reservoirs found in Dawa Haiwaihe steep slope as well.更多还原
