  • The heterogeneity is objective character of reservoir and influences hydrocarbon occurrence,oil production,ultimate recovery factor and economic behavior.How to effectually characterize heterogeneity of the reservoir is a problem researched by geologists all the time.There are lots of characterized para-meters for the heterogeneity of the reservoir.But every parameter involves advantage and shortcoming.In the long-term experience of scientific research process,a new parameter to characterize the reservoir heterogeneity is proposed,which is permeability diversity coefficient.The heterogeneity degree of the reservoir can be characterized completely,truly and accurately by this parameter.Calculation method of this parameter is simple and convenient.The comparability is good,the criteria can be easily established and the computational accuracy is not influenced by sample numbers.In the practical application it acquires preferable effects.
