Bentonite Powder

الوصف

Oil Drilling Grade Bentonite is used in vertical drilling fluids to increase viscosity and filtration control. This mineral is also ideal in drilling fluids because it expands when exposed to water. This expansion helps down whole formations to be sealed from invading drilling fluids. The Drilling bentonite extracts the drill cuttings from around the drill bit, which are then floated to the surface. Bentonite also serves to cool and lubricate the drill bit as well as seals the drill hole against seepage and to prevent wall cave-ins. It is mainly use in fresh pure water rotary drilling conditions as water quality will affect bentonite performance. The quantity of bentonite used is variable depending upon the depth of the hole to be drilled. Generally one tone of bentonite is used to prepare about **0 barrels of mud.  Less -
