摘要
定向井工艺首次在北京复杂基岩地层地热钻井中的成功应用,对指导类似地区地热资源的勘探开发具有重要的借鉴意义。本文以YR-2定向井的施工过程为例,介绍了定向井的钻井工程设计和区域地质构造条件,详细论述了定向井的地质构造条件、井身质量参数及钻探施工工艺,对应用定向井工艺的经验进行了总结。
This paper introduces the first successful application of directional wells to geothermal drilling in complex rock formations, which plays an important reference role in guiding the exploration and development of geothermal resources in similar areas. Taking the construction of the YR-2 directional wells as an example, this paper introduces the drilling project design and regional geological structure of the directional wells, discusses the geological structure conditions, well quality parameters and drilling technology in detail, and gives a summary of the experiences gained in the application of the directional drilling technology.
