中文摘要 | 水錐現象對於生產井而言是一個非常不利的情形。對氣井而言,除了會降低產率 外,也會縮短生產井之生產壽命,而使油氣之採收率降低。因此,有必要對水錐現象發 生之機制進行模擬研究。 本研究利用 ECLIPSE-100 軟體進行水錐現象之模擬。先建立一個 單純的氣田模型,只有一口生產井來進行模擬。除了將模型單純化之外,對於影響水錐現象 的因素也只鎖定在穿孔區間以及產率兩個因素,以免無法明確地了解單一因素對水錐所造成 的影響,期能對水錐現象有所了解,進而研擬出防制之對策,供現場單位日後在完井作業及 生產時產率控制之參考。 |
英文摘要 | TCS Field is the biggest gas field in Taiwan. Due to the increasing market demands, resulting from a number of natural gas power plants raised, CPC decided to use TCS Field as an underground storage for Liqudfied Natural Gas (LNG) to meet the demand/supply in the future. Injedction/production wells are required by the underground storage project in the future. One of the questions existed while designing the well head equipment is that, will the composition of each component change in the future ﹖ As a consequence, it is necessary to predict the mole fraction composition of each component using the compositional simulation. The Equation of State (EOS) and the compositional model were established in this study based upon the fluid analysis of TCS-10 well. Utilizing the model above, the prediction of the composition of each component for the next 10 years have been completed for the field design. Also, the study compares results of each composition with enhanced injection rate. |
