A System Analysis of Production Test in Condensate Gas Well

During the production testing in condensate gas well, it is necessary to predict the well head pressures of the well with high geotherm and high formation pressure which will be soon put into testing, to design producing pressure drops and make up a working system for the production test according to the basic circumstances of the well, to adjust the producing pressure drops in light of test results so as to guarantee the production test to be smoothly carried out, and to analyze gas well performance in time so as to achieve the accurate information about the gas bearing formation. In the paper, predicting various pressures of the condensate gas well during testing by use of the system analysis method is proposed after analyzing the existent problems in production test in the condensate gas well with high temperature and high pressure; the inflow and outflow models on which the influence of phase states was considered are set up on the basis of analyzing a series of properties of the production tests in the condensate wells; the temperature calculation model and the calculation method of biphasic flow in pipeline are introduced; and finally the method of uniting on site test with theoretic calculation is put forward in accordance with the properties of complicated running in the pipe string of the production test.
