A New Method of Source Rock Prediction Based on Q Cluster in YB Region, Northern Sichuan Basin

On the basis of clustering theory, Q cluster is applied to predict source rocks. Distance coefficient and similarity coefficient are calculated, and the shortest distance method is used to analyze the oil shale samples. Then, a prediction map of the oil sources distribution is drawn with Q point-group analysis. Finally by the analysis of organic geochemistry distribution in YB area, the location of source rock is determined.
