Mid-deep strata with high temperature and overpressure of Dongfang area in Yinggehai Basin has become the focus of oil and gas exploration in recent years,and significant exploration breakthrough was made in the first section of Huangliu Formation.However,characteristics of high resolution sequence stratigraphy,reservoir sedimentary microfacies and evolution and subtle trap in it need to be revealed.Based on substantial cores,drilling,well logging and 3-D seismic data,high resolution sequence stratigraphy framework of the first section in Huangliu Formation of Dongfang area was constructed,and the types,sedimentary characteristics and evolution of sedimentary microfacies in different sequence units were investigated.In addition,characteristics and distribution of the favorable reservoir as well as subtle traps were revealed.And finally,the exploration direction of subtle reservoir in this area was discussed.The results show that the first section of Huangliu Formation can be divided into five parasequence sets,they are Ps1,Ps2,Ps3,Ps4 and Ps5 from bottom to top in the order.Ps1,Ps2 and Ps3 all belong to lowstand system tract,while Ps4 and Ps5 correspond to transgressive system tract and highstand system tract,respectively.There are neritic turbidite fan and neritic facies in the lowstand system tract.The neritic turbidite fan consists of two kinds of subfacies-middle fan and outer fan,and the former is predominant which includes three kinds of microfacies-turbidite channel,inter channel deposition and natural levee,while in both of transgressive system tract and highstand system tract shelf mud and neritic sand bar developed.Turbidite channel sandstone is the primary reservoir in Huangliu Formation of Dongfang area,and the lowstand system tract is the most important exploration strata.There are mainly structural-lithologic composite reservoirs in the diapiric structure zone,and updip pinchout lithologic reservoirs in the wings of diapiric structure zone,and lenticular sandstone lithologic reservoirs in western Dongfang area which is non-diapiric structure zone.
