摘　　要：四川川西康定地区地热资源十分丰富,该地区先后施工了ZK201井、ZK203井、ZK206井。从井深200m开始,施工温度急剧升高,并伴有热水蒸汽喷出,热储条件良好。为了进一步开发当地地热资源,充分利用地热储层,提高蒸汽的产量,我单位对超高温定向井和水平井的施工进行了多方面的探索和研究,并提出了超高温环境下定向过程中的关键技术难点和解决方法,为现场高温定向施工提供了有力保证。The geothermal resources in Kangding area of western Sichuan are very rich,and ZK201,ZK203 and ZK206 Wells have been constructed in this area.Starting from the depth of the well 200m,the construction temperature rises sharply,accompanied by hot water steam ejecta,and the heat storage conditions are good.In order to further develop local geothermal resources,make full use of geothermal reservoirs,and improve steam production,our unit has conducted multiple exploration and research on the construction of ultra-high temperature directional Wells and horizontal Wells,and proposed key technical difficulties and solutions in the orientation process under ultra-high temperature environment,providing a strong guarantee for the on-site high-temperature directional construction.
