| Abstract: | 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 explo- ration 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. |
