基于成岩储集相分类的致密储层孔隙度建模
Porosity Modeling of Tight Reservoir Based on Diagenetic Reservoir Facies Classification
摘要
Abstract
It is difficult to accurately evaluate physical parameters such as porosity with a unified model for tight gas reservoir which characterized by strong heterogeneity.To solve this problem, the classification evaluation system of various diagenetic reservoir facies and their dominant role in the change of porosity have been analyzed.Based on the diagenetic reservoir facies classification, the porosity of tight gas reservoirs is determined.Using the matching relation of logging response of the classified diagenetic reservoirs facies,a multi-parameter logging quantitative evaluation method based on grey theory is established for diagenetic reservoirs facies,as well as a porosity logging evaluation model for reservoirs of classified diagenetic reservoirs facies.Because various logging curves have a certain degree of response to porosity,multiple parameters such as deviation degree, dispersion, and correlation of the classification model are used to comprehensively determine the porosity.Applying this model to the actual data processing to verify its effect.It is found that the data points in the classification model have a relatively concentrated distribution trend and a relatively obvious linear relationship, w hich means reasonableness of the model and can be used to evaluate physical parameters of the tight gas res-ervoirs.关键词
