| The north steep slope zone of Dongying Depression has great potential in oil resource and as the the usage of 3-d seismic data in the last decade,the exploration of oil and gas into the stage of sandy glavel body lithological oil-gas pool exploration.In this thesis,writer take the north steep slope zone of Dongying Dpression as target area and take Sha III- and Sha IV Member as purpose stratum, study on tectonic,deposition and reservoir,emphasesing on analying of forming of dynamic background of tectonic,sedimentary sequence and pool-forming.There are main conclusions and views as follow.In the tectonic aspectm,applying with structural geometry and dynamic s,tectonic active stage and evolution regularity have been studied in detail and tectonic sequence divised.At the same time, The structural feature and style have b-een analyzed and the emphasis has been put on the structur al dynamics feature of the north belt of Dongying depression.on the basis of above,the controlling michanisim has been analyze of developing on acco mmodation,sediementary facies,special low system track by multistage struct ural slope-Break slope.In the sedimentary sequence aspectm, applying with high resolution sequence and combing with seismic,well logging and well core,the the high resolution sequence framework and the sequence model of sandy glavel body fan has been built up,emphasesing on analying of high re solution sequence units model,correlation model and relationship with ol-gas in delta fan and the offshore fan sedimentsry system.In the sedimentary sequence aspectm, applying with the theories of petroleum system,the hydrocarbon generation,explulsion,migration and accumulation have been detailedly studied.Through the hydrocarbon generation simulation and combed with homogenization temperatures of fluid inclusion,thc time and process of hydrocarbon migration and accumulation, and on above basis, 4 kinds of oil formation mode has been summarized.
