Abstract: Through mathematical models of the numerical well testing and unstable testing by using radial grid, a new application method which optimizes the respective advantages of numerical well testing and unstable well testing is introduced. By using this method, the changes of the formation pressure by time can be obtained from numerical well test, and then controlled reserves of a single wel can be obtained from the pressure change by time. The advantage of using the unstable testing is to obtain physical parameters of a single well. The formation pressure obtained by analyzing two gas fields of Tarim Kela with this method is more in line with actual conditions.
