| Abstract: | This paper summarizes the construction experience of a geothermal well in Hasuhai scenic spot of Inner Mongolia. The well completion depth is 2232.59m, Petroleum 30 type drilling rig was used by full face drilling with rotary positive three-cone bit and matching with PDC bit coring drilling process. This geothermal well has 3spud structure, 80 mesh wrapped 80 mesh wire wrapping filter pipe. Both the water temperature and the water output meet the design requirements after well completion. The judgment and prevention measures of PDC bit balling are introduced. |
