新形势下地热井高质量钻井施工技术剖析

Analysis of high-quality drilling construction technology for geothermal wells under the new situation

摘要:

地热钻探施工是一项非常严谨的工程，其专业性较强，设备和工艺器具配套是施工顺利进行的保证。提高队伍的专业性素质和单位的技术力量，在新形势下采用先进的工艺技术，是地热井高质量钻完井的关键。加之我国的地热市场正在向地层深部拓展，施工难度也会加大，施工单位只要拥有自己独特的施工技术和特点，就能够在市场上立足自身发展的势头，发挥竞争优势。本文针对地热井施工的一些具体问题进行了剖析，指出多工艺空气钻进技术是优质、高效开发深部地热和地下水资源的有效方法。

Abstract:

Geothermal drilling construction is a rigorous work with high professional requirements， and the matched equipment and process tools are the guarantee for the smooth progress of construction. It is critical to improve the professional quality of the team and the technical capacity of the unit， as well as adopting advanced technology under the new situation. In addition， China's geothermal market is expanding toward into the deep strata， which brings increasing construction difficulties. Construction enterprises with proprietary construction technologies and characteristics can maintain development momentum and gain competitive advantages in the market. This paper analyzes some specific problems in geothermal well construction， and points out that multi-process air drilling is an effective method for high-quality and efficient exploitation of deep geothermal and groundwater resources.
