中文摘要 | 本公司臺灣油礦探勘總處在寶山構造新鑽寶山14號井,為瞭解寶山構造之原始蘊 藏量及水沖排可行性,乃委託探採研究所進行油氣層模擬,作為未來現場單位擬訂生產方案 之依據。因寶山 3 號井 PVT 分析報告顯示其 Bo 值大於 5,屬於揮發性油田,如以黑油模 式進行模擬, 其誤差會相當大。 根據國外文獻建議, 此種油田需以成份模擬( Compositional Simulation )進行, 本研究因此採用成份模擬來進行寶山油田之模擬工作 ,以確認其原始蘊藏量並預測未來採用水沖排之可行性,供現場單位之參考。 由研究結果顯示其原始油蘊藏量為 6.37 萬公秉,原始氣蘊藏量為 3.42 千萬立方公尺。採 用水沖排則因寶山 3 號井與寶山 14 號井相距甚近,水貫穿太快, 沖排面積太小等因素而 不可行。 |
英文摘要 | Recently, Taiwan Petroleum Exploration Division (TPED) of Chinese Petroleum Corporation has drilled PS-14 well in PaoShan (PS) structure. In order to understand the potential of PS field. The Exploration and Development Research Institute (EDRI) is in charge of the evaluation of the original oil in place and the feasibility of the water flooding in PS field using reservoir simulation. PS field is a volatile oil reservoir because its Bo appears to be avobe 5 according to the PVT analysis conducted in the Core Lab using core plugs from PS-3 well. According to the references (fig. 1), it is shown that the compositional simulation must be used in the volatile oil reservoir so the errors are able to be reduced. Therefore, EDRI decided to use the compositional simulation (Eclipse300) to evaluate PS field to get a more accurate estimation of the original oil in place as well as the future production performance. The simulation results reveal that, the original oil in place of the PS field is about 63670 KL and the original gas in place is some 34.2 MMSCM. The results also indicate that the water flooding is not feasible due to the factors that the distance between PS-3 and Ps-14 wells is very short which is likely to result in quick water break-through and the small flooding area. |
