Abstract:The prediction of oil-bearing ability in sand body has certainly some difficulty and risk. Nevertheless , because the oil-bearing ability in all kinds of sand bodies always has some characters and regularities, therefore, in a condition of following the geologic feature and regularities, it can use multi-information such as geology, geophysics and reservoir engineering to scientifically and reasonably predict oil bearing ability in sand body after analyzing the geologic and geophysical conditions of oil bearing ability in sand body. The paper mainly used the results of oil bearing ability separately predicted by optimized seismic attributes,porosity- predicted results, neural network method and support vector machine method to carry out integra-tive judge of oil-bearing ability in channel sand bodies situated in upper part of Eg on the north slope of Chengdong uplift,which achieved preliminary success.
