///Slope exploration is the best prospective area of Huanghua Depression, Dagang oilfield, especially at the slope of Gangxi and Guanxi, because forming various reservoirs in the period between Paleocene and Neogene on it, therefore doing the fine reservoir prediction is the key way of progressive exploration and development. Application of EPSTM reservoir is new generation software of reservoir prediction, realize the integration of prediction and lithology interpretation and make the better application at the slope of Gangxi and Guanxi.
