Abstract

Abstract: To further improve the accuracy and reliability of production data analysis for wells with vertical fractures in low-permeability tight gas reservoirs, the paper uses a point-sink function model for vertical fractures, and establishes an expression of side wall pressure with uniform flows in Laplace space, based on which typical curve charts of Blasingame-mode production data analysis are mapped through numerical inversion. A rapid and simple chart matching method is obtained after the characteristics of each flowing stage on the charts are analyzed. Through production data matching, effective parameters such as well control reserves, permeability, single well drainage area and radius, and fracture half-length etc. are gained, which can be used to evaluate single-well fracturing effect rapidly and effectively
