Abstract：With the deepening tight oil exploration research,the low accuracy of “sweet spot” reservoir prediction and large calibration error of horizontal well trajectory in time profile seriously limit the exploration and development effects. Taking the Fuyu reservoir of the Cretaceous Quantou Formation in the Songliao Basin as an example,this paper employs the GeoEast system sharing platform. Based on fine structural interpretation,the paper adopts the small time-window to extract seismic attributes and select the attributes that can reflect the distribution of local sand bodies. Additionally,seismic multi-attribute fusion is conducted,and the predicted coincidence rate of sand bodies is greatly increased by more than 10%. At the same time,the space-variant velocity field is built to carry out the steering while drilling of horizontal wells in the depth domain,which avoids the calibration distortion of horizontal well trajectory in the time profile. Finally,the seismic steering accuracy of horizontal wells and the drilling rate of sandstone are improved. Thus,it provides strong technical support for the exploration and development of tight oil.
