Product Description
Bentonite CP-DRI is used in vertical drilling fluids to increase viscosity and filtration control. CP-DRI is also ideal in drilling fluids because it expands when exposed to water. This expansion helps down holes 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.
Advantages:
Good suspension
High thixotropy
Little filtrated volume
Excellent capacity of making mud
Easy to adjust the density of the well drilling slurry

Application:
CP-DRI is suitable for all type of freshwater mud rotary drilling.
CP-DRI can also be used as a seal for earthen structures, slurry trenching, tunnel boring and foundation drill.
Mixing and dosage:
Mixing ratios are based on the use of freshwater; water purity will affect bentonite performance. For best results, acidic and hard make-up water should be pretreated with SODA ASH to a pH of 8.5-9.5. Add PREMIUM GEL slowly through jet/hopper mixer.The quantity of bentonite used is variable depending upon the depth of the hole to be drilled. Generally one tonne of bentonite is used to prepare about 100 barrels of mud.
Established in 2006, Hangzhou Camp-Shinning Co., Ltd. is a professional manufacturer of
(1) modified Bentonite Rheological additive with the annual capacity of 20000metric tons
(2) of foundry bentonite and oil drilling bentonite with the annual capacity of 50000metric tons.
(3) of activated clay with the annual capacity of 20000metric tons.
Our moidified bentonite rheological additive has two systems: one is solvent based system and another is water based system, which is widely used in coatings, paints, inks, sealants, lubricating grease. And our Foundry bentontite and oil drilling bentonite is widely used in Foundry industry and oil durilling mud industry, and waste water treatment, waterproof engineering industry, precision casting, metallurgical industry and per litter, etc.
We have our own raw bentonite mine, it makes us have superoirity in quality and price, depend on good and continuous quality and competitive price, our products has been widely export to USA, Canada, Europe, SOUTH America, Middle East and other countries, we are occupying more and more market share, and more and more customers are using our products to replace top brand products.
