Abstract：The main reservoirs of second members of Shahejie formation in Xiaoying are delta front sheet sand.Because of thin layers and fast horizontal changes of sand,the determination of sand boundaries is the critical factor to succeed on the exploration.Aiming at the exploration difficulties of low resolution of seismic data and the indeterminacy of sand pinchout lines,this paper goes on the fine descriptions for the main oil-bearing sandstone pinchout line through the spectral imaging and phase attribute analysis on the basis of the substratum correlation and statistical analysis of drilling.And the comprehensive geological evaluation is undergone in conjunction with the actual drilling comments.Thus,the good development results are achieved.
