Located at the bottom wall of Daxing fault,Xing 9 condensate gas reservoir is gas-condensate reservoir with litho-structural characteristic,whose edge and bottom water are not active.It is the elastic-soluble gas-drived gas reservoir with high content of condensate and maximum retrograde condensed liquid.Its development is characterized by that of a closed constant-volume gas reservoir.This paper provides a suitable program including operation methods,well spacing,reasonable well production and technology adopted based on the reservoir characteristics.Four well-spacing methods are compared,and the anomalous triangular well pattern of 800m is adopted.Combined with minimum liquid-carrying capability of the gas,reasonable gas output per well is determined to control pressure difference reasonably and enhance condensate oil recovery by adopting the single-point test and analyzing the field production.This study proposes some strategies for the problems of the gas reservoir and seeks for some novel technologies,such as gas testing technology with perforating under negative pressure and discharge water with continuous high-pressure-promoting.All of the methods are applied to Xing 9 gas reservoir successfully,which provides references for efficient and rational development of similar reservoirs.
