针对气田进入末期开采,尚具一定经济开采价值,结合目前气田生产井产气量约11.0×104m3/d,井口压力低下,用户对用气压力要求越来越高,严重制约气井正常生产。本文分析气井、管网流程,找出目前生产存在的问题,提出对地面工艺改造,为气田低压气采出找到出路,达到提高气田最终采收率、缓上或不上增压,节约投资的目的。
In view of the fact that the gas field enters the final stage of mining, it still has certain value for economic exploitation. Combined with the gas production in the gas field production wells is about 11.0 × 104m3 / d, the pressure at the wellhead is low, and the user’s demand for gas pressure is getting higher and higher, seriously restricting the normal gas production. In this paper, the gas well and pipe network flow are analyzed to find out the problems existing in the production. It is proposed to revamp the groundwork and to find a way out for the low pressure gas production in the gas field so as to increase the ultimate recovery rate of the gas field, slow or not increase the pressure and save investment purpose.
