river deposi-tion,so the reservoir architecture characterization is difficult with wide spacing from350to400 m.Taking Lm943sand body in the oilfield as an example,the key parameters in reservoir architecture are described.Firstly,subzonecorrelation is carried out using logging and seismic data.Taking an arbitrary well as a reference orientation in one di-rection,contrasting well by well from intertwined direction,the distribution and superimposed relationships of thesand body are analyzed with sedimentary 

facies-controlled method.Secondly,the abandoned channel and single pointbar are identified using the idea of“abandon the point bar to find the abandoned channel”and the method of multi-at-tribute fusion stratal slice to guide the characterization of reservoir configuration interface.Finally

,the characterizationof lateral accretion interlayer is completed with the horizontal well data.The result of Lm943 sand body reservoir ar-chitecture characterization effectively guides remaining oil development and the recovery is expected to be increased by15%.The proposed method can p

rovide reference for similar reservoir characterization in offshore oilfields.Key
