Abstract: The Li 38 block of Dongying depression lies the northeast nosing-structure in Binxian prominence, which also is oil and gas in Lijin sag to arch in Binxian prominence to migration to have to pass through, it has the geological condition to form the complicated-hiding oil and gas reservoir in the Shahejie Formation. 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 explore and produce in the Shahejie formation, of Li 38 block.
