Considering the difficulty of identifying fluid contacts on seismic profiles which have no significant fluid responses, the method and application prerequisites of Common Contour Binning Stacking Technique for Pinpointing Gas-Water, Gas-Oil and Oil-Water Contacts. Through this method, the fluid contacts of anticline gas reservoir which has “flat spot” and structural-lithological trap reservoir that has no “flat spot” have been identified. The results and effectiveness of Common Contour Binning Stacking Method have been discussed and the application prerequisites have also been summarized.
