Abstract: Negative structural belt in Gudong -Hongliu lies in buried mountain of Gudong and structural arch of Kendong, which has the negative structure geological feature, simultaneously also is oil and gas in Gunan sag to arch in Kendong to migration to have to pass through, it has the geological condition to form the hiding oil and gas reservoir. In this paper, structural features, reservoir distribution, reservoir conditions, and other aspects of distribution have been Comprehensive analysic, It evaluates deeply hydrocarbon accumulation and distribution in the negative structural blet, It is an important guiding significance to deepen oil and gas exploration of the shallow reservoir in negative structureal belt of Gudong.
