More Information
Summary:Changshen gas reservoir is a fracture-pore volcanic reservoir and contains high content of CO 2 . In view of this specificity, the percolation characteristics and years of stable production are analyzed by stage balance depletion and constant flow depletion experiments. Studies show that the P-G P curve is mainly affected by type of gas, pressure, and temperature. In the same conditions, the production effect of fracture-double porosity media core is better than that of matrix-single porosity media core. And the years of stable production are related to radius of single-well controlled, production of single well, and type of gas reservoir.
