The Research Of Digging Xing89Area Remaining Oil Potential Along Faults With Directional Well

Remaining oil distribution study is a worldwide difficult problem,the purpose of theremaining oil study is to determine the number and distribution of the proven remainingresources,so as technology,economy can give maximum production,in order to get as high aspossible oil and gas recovery factor.Therefore,residual oil should take its original meaning.Bedefined as developde reservoir or has not been produced in the formation of oil and gas.Remaining oil distribution study is a worldwide difficult problem,the purpose of theremaining oil study is to determine the number and distribution of the proven remainingresources,so as technology,economy can give maximum production,in order to get as high aspossible oil and gas recovery factor.This thesis comes from daqing oilfield limited liability company the fifth productionplant,the purpose is for oil field near the fault at the high water cut stage,due to the blockingeffect of fault,can cause lacal injection production imperfect,making the enrichment ofremaining oil.if use vertical well extract the remaining oil along faults,there will be a problemof economic efficiency that is making economic efficiency not high.This thesis according tofaul characteristics,reservoir characteristics and injection production relationship analysis,design of directional well digging the remaining oil near the fault,improve the reservoir usingcondition,to explore a new method for digging remaining oil in fault edge.Paper researchcontent is first set up three dimensional structure model in study area,on the basis of loggingdata and high precision3d seismic data,to resarch of the micro structure of purposelayer,letting micro structure at cell level.Followed by the integrated optimization of remainingoil distribution and structural model for directional well,optimization of remaining oilmore,construct good position as target of direction well.Finally determine the directional wellgeological design,determine the target area and the well trajectory parameters,preparation ofdirectional well geological design scheme.
