摘要：
The actual condensate oil production rate was far lower than that in the theoretical design index in the first few years' production of No. 1 Production Plant of the Samandepe Gas Field, the Right Bank of the Amu Darya River of Turkmenistan, for that the partner raised serious questions about our side and required a scientific and reasonable explanation. To accurately determine the potential content of condensate oil in this field and the condensate oil production rate in this plant, we established technical codes for fluid sampling and test methodologies for fluid analysis, based on which we analyzed and determined the compositions of well fluid and condensate oil content in this field, and then the relevant parameters and potential content of condensate oil were calculated and compared by the Russian method and our newly-established method. The following results were demonstrated. (1) In the newly-established method, the compositions of natural gas are required to include C10+ and N2, He, H2, O2+Ar, CO2, and H2S and the components of condensate oil required to exceed C30 +; (2) The condensate oil content of this field is calculated to be 77.27 g/m3 by the Russian method and 76.21 g/m3 by the new method, indicating that both methods have identical results; (3) Compared with the other old methods, this new method is of higher accuracy and the calculated results are more reliable. It is concluded that this new method can not only be used to determine the potential content of condensate oil in this field but solve the major technical issue perplexing Block A of the CNPC Turkmenistan Amu Darya Natural Gas Company. It also provides a robust technical support for the further production-expansion transformation of Block A and the nextstep development design for Block B, and the productivity construction of Project Ⅱ. © 2018, Natural Gas Industry Journal Agency.
