The condensate well testing is a currently world wide challenge as its complicated phase behaviour.So it is a cutting edge research direction of the well testing theory and application. Usually the testing data from a condensate well could not be interpreted correctly if only by means of normal well testing analysis model.It already became one of the major problems of those abnormal over pressure condensate wells in Yaha field, Tarim and it seriously affect the successful ratio of well testing job. An applicable solution is urgently required to direct how to improve the quality of condensate well testing. A new integrated well testing analyze method, which named “6+1”,and a modified one point productivity evaluation technology are put forward from many years field experience in Yaha condensate gas reservoir, which includes well testing theory, procedures and in field practice. A theoretically dynamic analysis of the multi-payzone gas well performance is conducted. The presented integrated technology can be used in well testing procedure and analysis and testing data interpretation of Tarim abnormal over pressure condensate gas wells.
