The Preliminary Research on Carbonate Gas Reservoir Structural Fracture Prediction and the Quantitative Parameter Field Formation

During the Carbonate gas reservoir's numerical simulation process, it is often short of exact and quantitative fracture model, especially porosity and permeability models. Based on this condition, this paper predicts carbonate gas reservoir structural fractures according to its cause of fracture generating, and uses the multivariate statistical analysis to establish the correlative relation between fracture interval and reservoir thickness and porosity, which is able to predict the interval change in cross-hole area. Finally people apply this method in Jialingjiang gas reservoir and the results confirm its feasibility.This means provides theory gist for analogous reservoir forming the fine 3D quantitative parameter field.
