Due to the problems being difficult to extract seismic attribute by using of mathematic theory and the poor sedimentary facies in attribute obtained by using time-widiow,it was proposed that evaluation was performed in combination with the quality of seismic data.In consideration of the problems,forward technology was used to determine the sensitive seismic attributes and time-window of attributes.The research shows that extracting the RMS is in good correspondence with sand development.The attribute extracted by using the forward technology is determined in combination with forward simulation,it indicates well the sand distribution in plane and the sand prediction is consistent with geologic regulation.The reliability is demonstrated in consequent well drilling,it shows that the forward technique can be used for guiding sand prediction.
