| 摘 要： | 贵州省碳酸盐岩地层分布广泛,溶洞、溶隙、裂隙发育。在地热深井钻进过程中,经常在热储层钻遇溶洞,出于储层保护目的,常常采取顶漏钻进措施。在贵州铜仁ZK2地热井热储层遇到此情况时,采用了低渗透成膜钻井液顶漏钻进,节约了钻探成本,同时能将岩屑及时排出,保证了钻井安全,为低渗透成膜钻井液在深部地热钻井中的应用提供了宝贵的经验。

| Abstract: | Carbonate formations are widely distributed in Guizhou Province with karst caves, karst cracks and joint cracks developing. Karst caves are frequently encountered in deep geothermal well drilling operation. For the purpose of reservoir protection, it is usual to drill against loss circulation. In geothermal reservoir of ZK2 geothermal well of Guizhou, by drilling against loss circulation with low permeability film forming drilling fluid, the cost was reduced and the cuttings were discharged in time. This safe drilling case provides its experience for the application of low permeability film forming drilling fluid in deep geothermal well drilling. |
