Common Mud Materials for Drilling

Advantages of mud powder: strong wall fixation, strong cohesion of sediment in the hole, fast sedimentation speed, low labor intensity of personnel, no pollution, fast pulping, no waste, easy preservation, easy to deteriorate. It is easy to use can be directly dissolved in water evenly. However, the use of bentonite requires mechanical mixing, personnel handling, dust flying, high pollution, easy waste, long-term accumulation like mountains, easy deterioration. It also requires two more people to complete the mud mixing process with minimal mud production.

Mud powder dosage: Adjust the pH value of the slurry preparation water to 8-10 add 0.8-1.8/ 1000L. Drilling mud additives

Method of using mud powder: On site, chemical mud is usually used 5?: Mix 5 cubic meters of clean water, during the mixing process, if there is a slight viscosity to the touch, it can start to form a thread like shape; The ratio of pure alkali alkali powder is 0.3, -0.5,. Then, use an air compressor to put the air pressure into the pool for sufficient mud mixing. Sodium carbonate (soda ash) has the chemical formula Na2C03, commonly known as soda ash soda ash. It is an important basic chemical raw material the main product of the soda ash industry.

Usually white powder, easily decomposes at high temperatures, soluble in water, the aqueous solution is alkaline. Soda ash will deliquescence in humid air, slowly absorbing carbon dioxide water, some will become sodium bicarbonate. Therefore, packaging should be strict, otherwise it will absorb moisture clump, sodium carbonate water will generate Na2C03? 10H20.

Carboxymethyl cellulose (CMC) is a non-toxic tasteless white flocculent powder with stable performance is easily soluble in water. Its aqueous solution is neutral alkaline transparent viscous liquid, soluble in other water-soluble adhesives resins, insoluble in organic solvents such as ethanol. CMC can be used as an adhesive, thickener, suspension agent, emulsifier, dispersant, stabilizer, sizing agent, etc
