According to the seepage characteristics of abnormally high pressure gas reservoirs in Kela-2 gas field, combined with dynamic and static analysis and gas reservoir engineering methods, an effective well pattern of numerical well test is selected. Based on well data such as regional structure, effective thickness and porosity, well permeability and high pressure physical parameters Such as rock and fluid data, to establish the gas reservoir model for numerical well testing. Then, the well model was established by using the production history of each well. Based on wellhead test data from 2007 to 2008 in Kela-2 gas field and cable test data from September to October 2008, Numerical well test technique was used to interpret the pressure recovery data and predict the production of the Kela 2 gas field. The physical parameters reflecting the real geological characteristics and production dynamics of the reservoir were obtained, and the data interpretation techniques and dynamic prediction methods suitable for the abnormal gas field were formed.
