Abstract：The K-47 well zone is major development area of Kenxi oilfield in Shengli Oilfield,the main oil-bearing segments are Ng and Ed that enter the middle-late period of oilfield development but still have some development potential.Using ordinary seismic data is difficult to accurately describe the lateral distribution of cross-hole thin-interbedded sandstone/mudstone because of the limitation in resolution, but using cross-hole seismic data can obtain more precious image of cross-hole geologic targets.Using high-resolution cross-hole seismic data and on the basis of fine correlation of minor layers the paper described the lateral variation of cross-hole thin reservoir for two pairs of wells and created the fine cross-hole thin interbedded sandstone/mudstone geologic model in K-47 well zone in combination with inverted section in the depth domain, which laid a solid foundation for later recreation of 3-D fine geologic model and further adjustment of development formations
