| 中文摘要:贵州省岩溶裂隙地层发育，地层复杂，地热勘探井施工难度大。根据磺化沥青的基本特性，分析了磺化沥青钻井液护壁防塌机理，确定了性能合理的磺化沥青钻井液配方，并在贵州省铜仁市西部地区地热水资源整装勘查沿河勘查区块地热勘探孔（ZK2）进行了生产应用。实际施工表明，磺化沥青钻井液护壁防塌效果良好，提高了钻井效率，取得了良好的经济效益。结合实际应用情况对磺化沥青在地热井施工中的使用提出了建议。 |

| Abstract:The geothermal exploration construction in Guizhou is difficult because of karst fracture formations and complex strata there. According to the characteristics of sulfonated asphalt, the analysis was made on the wall-protection and anti-collapse mechanism of sulfonated asphalt drilling fluid to determine its rational formula, and the production application was also made in ZK2 of geothermal water resource whole-mount exploration in west part of Tongling in Guizhou. In the actual construction inspection, it is proved that sulfonated asphalt drilling fluid has good anti-collapse effect with higher drilling efficiency. The rational suggestions are put forward to the use of sulfonated asphalt drilling fluid in geothermal well construction based on the field application experience. |
