综合指数法在神木气田储层非均质性应用
Application of the composite index method to the heterogeneity of reservoirs in Shenmu gas field
摘要
Abstract
Shenmu gas field is the typical tight gas reservoirs .The reservoir is densified in the later diagenesis ,leading to the general lower value of permeability .So there would be some limitation to use the traditional heterogeneity methods for characterization .In order to quan‐titatively investigate the reservoir heterogeneity degree of the study area ,this method of comprehensive index is used to characterize .The parameters using in this method are many , such as permeability ,porosity ,gas saturation ,clay content ,sand content ,mezzanine density , pore throat radius .Considering the reservoir densified in this area ,the first four main param‐eters are selected for the development efforts .Two methods of weight are used for reference to confirm mutually .Conclusions is that the two methods showed that the heterogeneity of the small layer is very strong ,and small layer of Tai 1 is the strongest ,fitting the cognition of the Tai 1 layer geological background .Also reflecting the controlling of deposition back‐ground on reservoir heterogeneity .关键词
