氣井伴產地層水的預測方法之改進

Improvement of Forecast Water out in Gas Well

摘要


氣井在生產過程中,一般取水樣分析以測定其鹽份含量變化,產水量增加,以及井口壓力突降等現象,研判氣井被邊際水侵入而伴產地層水之情形。本文介紹以井口動態曲線,預測氣井將被邊際水侵入伴產地層水之微兆,在尚未被地層水侵入前,能及時適當調節與控制產量,使地層水延緩侵入井眼內,可延長該氣井之生產年限,增加油氣採收量。

Reservoir engineer generally use water analyses, water production rate, or well head pressure to detect the formation water invasion. This paper focuses application of outflow performance to investigate the formation water invading into the wellbore. In this situation we should control production at a lower rate to prevent from water coming and water fingering, in order to enhanced the recovery of hydrocarbons.
