Drilling mud materials components

Performance of Mud Powder: Nepton Mud Powder is an imported product of advanced foreign technology. It is a water-soluble, easily mixed powder particle polymer that dissolves fully in water forms a semi transparent paste with high viscosity. The slurry precipitates impurities in the hole very quickly.

When drilling in the hole, the mud always remains clear transparent, the surface of the drill rod is clean. Due to the continuous movement of the drilling tool in the hole, the more uniform the chemical mud water mix, the stronger the viscosity, the faster the cohesion. Even if the mud returns to the mud pool, there are no impurities precipitates. A thin transparent paste like protective layer was formed around the hole wall. Drilling mud additives

It is non-toxic pollution-free, is generally used in foundation engineering construction such as pile foundation drilling Slurry wall. It has the ability to maintain borehole stability; Can be configured with high viscosity mud; Easy to reuse; The waste slurry is easy to degrade for treatment; High recycling rate; It can improve the friction bearing capacity of the pile foundation the adhesion ability of drilling cuttings, which is conducive to the rapid cleaning of drilling cuttings.

Adding high-density inert solid substances to the mud to increase its density without damaging its normal performance is collectively known as weighting agents. When the formation pore pressure is high, the liquid column pressure of ordinary mud cannot balance the formation pore pressure, which can easily cause accidents such as well collapse blowout. In this case, weighting agents need to be used.

The weighting agent commonly used in mud is Baryte (Barium sulfate), the Molecular formula is BaSO4. The pure product is a white powder with different colors when containing different impurities. The pure product density is 4.5g/cm3, the commercial product density is about 4.2g/cm3. In addition, there is limestone powder (CaCO2) with a density of 2.2-2.9g/cm3, which is easily soluble in acid has the characteristic of protecting oil layers. Lead sulfide (PbS), density 7.5-7.6g/cm3. Magnetite (Fe3O4), density 5.0-5.2g/cm3. Ilmenite above 4.5g/cm3.
