Abstract
Seismic attributes analysis technology,which uses mathematic and physical conversion into seismic data interpretation,is adopted to extract the information about lithology,gas-oil occurrence and physical property of a reservoir so as to provide technological support to gas-oil reservoir prediction.The pattern recognition technology of Seismic attributes has also been widely applied in the oil and gas reservoir prediction.Upon selection of optimal seismic attributes,we used the multi-attribute clustering technology to establish the connection between multi-attributes and reservoir information.The specific cluster area may indicate an oil and gas rich area.We made prediction for the gas group of ZH2_1 in the Zhu-3 Depression.Favorable target area was selected for further exploration and development.
