土耳其高温地热钻井关键技术

Key Technology for High Temperature Geothermal Drilling in Turkey

摘要:

高温地热资源具有分布广泛、清洁环保的特点，世界各国都在加大高温地热资源的开发利用。土耳其ECOLOG公司Geo2E地热发电项目高温地热钻井实施过程中,针对区块高温地热钻井过程中存在的技术难点，从井身结构设计、钻井提速、抗高温钻井液、安全钻井技术等方面着手，进行相关技术的研究及应用，现场应用效果良好。该地区高温地热钻井成功经验能够为我国高温地热开发钻井施工提供有效借鉴，促进我国高温地热资源的经济高效利用。

Abstract:

Countries worldwide are increasing the exploitation of high temperature geothermal resources, due to their wide distribution, cleanliness and environment-friendliness. During drilling of the high temperature geothermal well of Geo2E, a geothermal power generating project of the Turkish company ECOLOG, research has been conducted on some drilling techniques to tackle high temperature geothermal drilling difficulties from various aspects, such as well structure design, drilling rate improvement, high-temperature resistant drilling fluid, safety drilling technology; and field application of these techniques has achieved good results. The successful high temperature geothermal drilling experiences in this area can be drawn on to enhance the economical and effective utilization of high temperature geothermal resources in China.
