中文摘要 | 地熱田依其溫度之高低及存在性質, 可分為乾蒸汽型、濕蒸汽型、熱乾岩石型及 地壓型等四種。就發電利用而言,以乾蒸汽型地熱之效率為最高,熱乾岩石型地熱雖然分佈 很廣,但其開發必須多鑽鑿熱水還原井,需增加鑽井費用,至於地壓型地熱能之利用與開發 ,目前尚無進展。而此四種地熱田中已廣被利用發電的以濕蒸汽型的為數最多,過去在地熱 鑽探時,除尋找高溫之蒸汽生產層外,對經濟而有績效之套管設計也非常重視,唯在鑽鑿生 產層時,上述各類型之地熱田所採用之鑽井流體也不盡相同,若使用不當之流體,將造成地 層污損,嚴重時會影響完井後之產能。籍由本文所提之鑽井及激產方法可達到經濟生產之目 的。 |
英文摘要 | Geothermal reservoirs vary widely in water temperature and structural conditions. Four of the most common types of reservoir are Dry Steam Type, Hydrothermal Type, High Temperature Rock Type and Geopressure Type. In geothermal power generation, the dry steam type reservoir is at a remarkably high efficiency. The high temperature rock type reservoir is spread widely, but it has to drill lots of reinjection well to develop and utilize the natural sources and will increase the cost of development. Up to now, it is rare to utilize the geopressure type reservoir with the current technology. The hydrothermal type reservoir is the most utilized by geothermal power generation system among the four types of reservoir mentioned above. In the early day of geothermal drilling, searching for the heat sources is the most important thing. Today, it is necessary to pay more attention to the economics and performances of the casing design. The types of drilling fluid run in the production zone drilling of the geothermal field are different. An improper drilling fluid being selected may create formation damage and reduce the productivity of the completion well severely. This article emphasizes the drilling operation and the stimulation practices that will offer some help to product efficiently and economically. |
