Abstract:

In recent years,13 high-pressure condense gas fields have been explored within Tarim Basin,such as the Yaha,
Jilake,Yingmaili,Dina,and so on. In the actual production,the condense gas will produce condense oil and then form the
two-phase of oil and gas,with the decrease of temperature and pressure. The transformation of this phase state will lead to the
difference between the explanation of production profile of the condense gas well and that of ordinary oil & gas well. According
to the specific features of condense gas reservoir in Yaha and Yingmaili,we use the production log data with 8 parameters to
calculate the output of the single layer of the condense gas well by using the method of PVT state diagram and the model of
oil/gas-phase flow,on the basis of analyzing the characteristics of log response. The application shows that
