In seismic reservoir prediction,we firstly deal with the abnormality of seismic attribute due to surface or seismic acquisition,misleading data processing and understand the seismic attribute with a variety of reservoir information;then we illustrate comprehensively the geological data,such as,sedimentary environment,tectonic features,lithology,physical property;finally the performance characteristics of the gas bearing property of reservoirs in the seismic attribute is determined in combination with geologic factors,no gas bearing prediction factors. Here,we must pay special attention to the conditions of the prediction method like as the prediction of gas bearing in one level of geological and reservoir factors. In this paper we use the singular direct decomposition method to reduce dimensionality of seismic attributes and optimize the deployment in the eastern Sulige gas field 3D seismic,since there is the ambiguity of reservoir prediction in the 3D seismic data attribute analysis. To a certain extent,this method reduces the ambiguity of the seismic reservoir and decrease the risk of well deployment in the gas development,getting the good effect on rolling evaluation and overall development.
