bentonite for drilling mud

Product Characteristics & Application :The standards for bentonite products used for drilling well slurry and civil projects refer to the standards issued by Geongraphical Mine Department petroleum industry Department and API standards of American Petroleum Association and European OCMA standard.They can be used as lubrication and wall protection slurry for petroleum drilling well.bridge stake base of construction projects,underground masts ,underground railway.tunnel drill and digging projects as well as anti-leaking materials for underground projects and reservoir dams.we have two kinds.Inorganic bentonite 1.Inorganic bentonite Item Bentonite Drilling Well Untreated Bentonite OCMA Bentonite Viscometer 600r/min readings ≥ 30 30 Yield Value / plastic viscosity of ≤ 3 1.5 6 Filtration volume / cm3 ≤ 15.0 16.0 75μm quality fraction /% ≤ 4.0 2.5 After split the plastic viscosity / (mpa s) ≥ 10 After filtration , Filtration volume / cm3/ ≤ 12.5 Moisture (105 ),quality fraction /% ≤ 13.0 Model No Apparent viscosity AV Mpa·s Plastic viscosity PV Mpa·s Yidld value YP b/100ft2 Filtration ml/30min Dry powder (-200 mesh)% BS-3 ≥ 8 ≥ 6 > 1 ≤ 45 > 90 HFGEL-40 > 15 ≥ 10 > 2 ≤ 45 > 90 2.Organo bentonite
