Abstract: The formation pattern and distribution characteristics of oil-gas pools were discussed on the basis of geological data from Gaoqing oil field.It was pointed out that there were some distinct features for the formation of oil-gas pools and various reserviors in the study area, and different structural units had distinct patterns for formation of oil-gas pools. The distribution of oil and gas was mainly controlled by Gaoqing fault and mudstone caprock of Guantao formation.
