Methods and applications of test well interpretation of fracturing data from coalbed methane wells
WANG Guorong
Abstract：Fracturing is the main reservoir stimulation and transformation project for coalbed methane wells.Permeability is the main parameter for measuring the permeability of coal reservoirs,and well testing is the main means of dynamically obtaining the permeability of coal reservoirs.The fracturing pressure data of coalbed methane wells can be analyzed using well testing interpretation methods and software analysis methods to obtain key parameters such as coal reservoir permeability.Analyzed the applicability conditions of well testing interpretation for fracturing data,proposed a reservoir model suitable for well testing interpretation of fracturing data,and developed a technical method for obtaining reservoir parameters during the fracturing period of coalbed methane wells through well testing interpretation.Selecting wells with different yields for well testing interpretation of fracturing data,analyzing the correlation between fracturing effect and well testing interpretation of fracturing data,establishing a method for evaluating fracturing effect through well testing interpretation,exploring the impact of different liquid and sand quantities on fracturing effect,the relationship between fracturing scale and gas production,and exploring the limit value of fracturing transformation.
