Jingbei Area Es₄-Es₃～4 Sequence Stratigraphy Study And Exploration Target Choice

The application of sequence stratigraphy theory and technology provide a newmethod for oil & gas-bearing basins .it is also an effective and advanced method toidentify and predict subtle reservoirs.Applied new theory and news method of sequence stratigraphy ,using seismic,drill,well-logging and core datum,this thesis,by means of establishing sequence divisionstandard,established sequence stratigraphy framework in the Jingbei area .Based thisresult,elaborate sequence stratigraphy division of Es4-Es34 key strata had been done,high-resolution sequence stratigraphy framework had been established.on the otherhand,the contrast of high resolution strata were done , the sedimentary faces and thedepositional system special distribution characteristics in key strata were analyzed ,and the strata distribution model of high-resolution isochronous strata was discussed.After the prediction of favorable source rock ,reservoir and cover layerdistribution,the subtle reservoir can be predicted.The theory and the method of sequence stratigraphy provide a new way to seeksubtle reservoir.after a long time research and study,combining theory withpractice,this thesis has achieved abundant conclusions and understandings thefollowing aspects were summarized.1 Summarized the reservoir method of Jingbei area Es4-Es34 sequencestratigraphy ,and map out the flow chart of subtle reservoir exploration2 Based on seismic,drill ,well logging and core data, etc., divided Jingbeiarea Es4-Es34 sequences and tracts.3 Established Jingbei area Es4-Es34 sequence stratigraphy framework reasonablyAnd describe sedimental facies,subtle facies and its distribution in model4 By the means of division and comparison of high-resolution sequencestratigraphy,evaluate reservoir , divide Es4 available reservoir and itsdistribution.5 On the research work base of elaborate structure explaination,buried hilllithological division, buried hill internal model, Es4 reservoir elaboratedescription, sedimental characteristic etc. ,carry through Jingbei area Es4-Es34available reservoir , capping bed form reservoir analysis of sand rockreservoir6 Predict Jingbei area available exploration targets...
