中文摘要 | 臺灣中部鐵砧山氣田歷經30餘年的生產,迄今以至生產末期,本研究主要目的乃針對鐵砧山氣田主斷層東西兩翼探討目前氣水界面之位置,以提供現場研判近一年來採較大產氣量生產至今氣層區域之現況,並提供鐵砧山儲氣窖營運管理之參考。 本文根據曾繼忠等人研究所區分之鐵砧山氣田四個不同區域,選擇目前鐵砧山儲氣窖主斷層東西兩翼(A1及A2)區域,進行相關生產井伴產水鹽度取樣分析以初步確認主斷層東西兩翼氣水界面之範圍,接著再利用油氣層模擬方法綜合研判目前鐵砧山儲氣窖主斷層東西兩翼氣水界面之位置。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(A1區域)合理的位置約在-2670m、東翼(A2區域)約在-2685m~-2690m。 |
英文摘要 | The TCS Field is a water drive gas reservoir. Gas-water contact (GWC) was moved upward after thirty years of production. Recently, large rate was set for the market demanding. To evaluate the effect of large production rate and confirm the level of GWC, a salinity analyses for several wells were performed. Also, simulation results were applied for the determination of GWC. Based on the results of previous study, TCS Field can be divided into four areas. In this case, we mainly concentrate on the gas storage (A1 and A2) area. Production water was sampled for several wells, which was screened by the depth of perforations and production layers. Salinity analysis was then performed. The results was combined with simulation ones to estimate the level of GWC. Our results show that the GWC is around -2670m in the A1 area and -2685m ~ -2690m in the A2 area at the moment (2003/10). |
