In productivity evaluation, the traditional systematic well test interpretation method requires that the formation pressure should be relatively stable at the end of each working system. For fractured vuggy condensate gas reservoirs, due to the rapid propagation of reservoir pressure, the change of reservoir formation pressure at similar production time points will be more obvious during the systematic well test. If the traditional systematic well test interpretation method is used to directly evaluate the productivity, there must be a large error. In order to make the productivity evaluation results of fractured vuggy condensate gas wells relatively accurate, a new productivity correction method is proposed in this study. The specific idea is to comprehensively correct the test pressure under each system by using the combination of pressure measurement point data selection and static pressure correction based on the stage elastic yield, so that the continuous flow pressure data can be reliably used, and the example verifies that the correction method is reliable. The advantages of this method are simple, easy to operate and strong usability.
