For obtaining CBM industrial output, the fracturing technology is mainly depended on. Fracturing pressure changes after the pump stops reflect crack and its formation conditions. By using fracturing pressure testing data after the pump stops, and the combination of well testing analysis theory and oil and gas seepage theory, according to the law of diminishing pressure, the pressure drop monitor data of the closed well test is analyzed to determine the relative parameters of fracture flow capacity, fracture half length, stress, so as to effectively analyze and evaluate the fracturing effect and the fracturing operation quality, which provides a scientific parameters basis for optimizing fracture design in coal-bed gas field, guides and develops coal-bed gas development plan. ©, 2015, Well Testing.
