柯克亚凝析油气田西五一（３）凝析油气藏循环注气先导试验区从１９９４年９月２日开始注气，至１９９９年６月结束，累积注气３８２ｘ１０８ｍ３，累积采气３．４７ｘ１０５ｍ３，注采比１．０５，累积采凝析油６．８３ｘ１０４ｔ．循环注气维持了地层能量，遏制了地下反凝析的进一步恶化，改善了地层的渗流能力，大大提高了凝析油的采收率。截止到１９９９年６月，凝析油采出程度达３８．６％，比衰竭式开发的采收率提高１７．６个百分点，开发效果良好。

Corka condensate field west five one (3) condensate reservoir gas injection pilot area from September 2, 1994 began to gas injection, to the end of June 1999, cumulative gas injection 382x108m3, the cumulative gas 3. 47x105m3, injection injection ratio of 1.05, the cumulative mining condensate 6.83x104t. Circulation gas injection to maintain the formation of energy to curb the further deterioration of underground anti-condensate, improved seepage capacity of the formation, greatly improving the recovery of condensate. As of June 1999, condensate recovery reached 38.6%, an increase of 17.6 percentage points over the depletion-based recovery and good development.
