低渗透成膜钻井液在贵州深部地热井中的应用
Application of Low Permeability Film Forming Drilling Fluid in Deep Geothermal Well in Guizhou Province
摘要
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 drill-ing against loss circulation with low permeability film forming drilling fluid, the cost was reduced and the cuttings were dis-charged in time.This safe drilling case provides its experience for the application of low permeability film forming drilling fluid in deep geothermal well drilling.关键词
