摘　　要：The Yaha Gas Condensate Field is the largest one discovered in China so far. In order to enhance the condensate recovery, gas recycling at 50 MPa has been implemented in Yaha field. Such high-pressure injection is very rare throughout the world. This paper offers the description of the geology and fluid phase behavior of Yaha field. The reservoir productivity and injectivity equa-tions, the optimal development and well patterns are presented. The follow-up investigation of the design implementation leads to the reasonable adjustment of the original development plan. The perforation principle and program of gas recycling for Yaha field are set up. The numerical simula-tion is used to predict the future production performance of gas recycling. Finally, a complete set of high-pressure gas recycling technology suite has been established. The field has come on-stream for one and a half year with condensate throughput of 590000 t in 2001, and fat profit returned. The success of high-pressure gas recycling in the Yaha field is of considerable importance from the theoretical and practical points of view and will considerably benefit the future development of other gas condensate fields in China.The Yaha Gas Condensate Field is the largest one discovered in China so far.
