陕西地区定向地热井施工工艺

Drilling Technique of Directional Geothermal Well in Shaanxi Area

以定向地热井的施工过程为例,介绍了定向井的地质概况、工程设计概况,详细对定向地热井的井眼轨迹控制、完井工艺技术进行了阐述,对应用定向井施工工艺技术进行总结。为今后在陕西地区渭河凹陷盆地内施工定向井奠定了基础,为开发地热资源积累了经验。

Taking the directional geothermal well as an example,the paper described the geological and designing situation about directional well,as well as the control technique of wellbore trajectories and well completion technoloty.Meanwhile,the summary of this technique laid a foundation for the development of directional geothermal well within the sunken basin of Shaanxi Weihe River,providing experience for the development of geothermal resources.
