摘要

中國石油公司從民國七十九年起進口印尼所生產之液化天然氣，利用鐵砧山之舊氣田儲存以調節供需。本論文探討使用CO_2為示蹤劑來監測天然氣儲存動態之可行性。本研究應用成份模擬來了解CO_2及注入氣在氣田中之流動路徑。鐵砧山天然氣含有大約2mole%之CO_2，而印尼進口之LNG中CO_2含量幾近0.0mole%；模擬結果發現，在生產井觀察CO_2濃度之變化有助於掌握天然氣儲存之動態。

Chinese Petroleum Corporation started the import of Liquified Natural Gas(LNG) from Indonesia in 1990 and utilized a depleted gas reservoir, Tiehchenshan Gas Field, to store the surplus LNG. With a compositional reservoir simulator, effort is made in this paper to investigate the feasibility of using CO_2 as tracers for monitoring the flow path of injected LNG. The CO_2 content in the Tiehchenshan gas and Indonesia LNG is around 2 mole% and 0 mole%, respectively. The simulation results indicate that monitoring the CO_2 concentration change at the producing wells would help the management of underground storage operations at Tiehchenshan Gas Field.
