鐵砧山氣田氣水界面鑑定在堵水增產及儲氣窖之應用
The Application of Gas Water Contact Verification for Improving Gas Recovery and Underground Gas Storage
摘要
本研究主要目的乃針對鐵砧山氣田注／產氣區域主斷層東西兩翼探討目前氣水界面之位置，以利停產氣井堵水增產井之篩選與研判穿孔區間之堵水區段，並提供鐵砧山儲氣窖營運管理之參考。本研究經由伴產水鹽分分析及模擬結果綜合研判，鐵砧山氣田目前（2003／10）氣水界面主斷層西翼合理的位置約在－2670m、東翼約在－2850m～－2690m。此外就已停產的氣井而言，鐵砧山注／產氣區域較佳之堵水增產井為TCS-35及TCS-2。其中TCS-35號井現場單位於2003／9／26已利用PosiSet回堵部分穿孔區間，目前生產狀況佳且已無地層水產出，保守估計尚可生產2年以上，約可增產2千9百萬立方公尺（NT＄1億4仟萬元）天然氣。

The TCS Field is a water drive gas reservoir. Recently, larger rate was to meet the market demanding To confirm the level of gas-water contact(GWC), a salinity analysis for several wells was performed. Also, simulation results were applied for the determination of GWC. Our results show that the GWC is around -2670m in the west side and -2685m~-2690m in the east. Also, the result can be used to verify candidate wells for improving gas recovery. From our screening, wells of TCS-35 and TCS-2 were the most suitable for making treatment. A PosiSet treatment to seal the partial penetration sections have been performed in well TCS-35 at September 26, 2003. After the treatment, the well keeps in good condition and no water is produced. Base on a concretive estimation, the production life can be increased two years and more than 29 MMm3/d of gas will be produced. It is equivalent to a 140 million NTD of income.
