Abstract: BW2 well area in Mabei oil field is characterized by low seismic resolution, thin reservoir and rapid variation laterally, and complex reservoir?control factors. Combined with the structural setting, the sedimentary feature and the reservoir rocks characteristics, this paper figured out 8 oil?bearing sand bodies by the geostatistic inversion using resistivity curves with sensitivity to the reservoir and makes comparisons by using given wells, and determined the vertical and lateral distribution of the oil?bearing sand bodies. The favorable oil?bearing areas were found out through plane position stacking of each sand body. This method can make up the shortage of low resolution of seismic data, effectively improve the vertical resolution of reservoirs
