Drilling Mud Treatment

To meet environmental protection standards, the drilling fluid must be processed when drilling in oil fields. The drilling fluid treatment is mainly aimed at the separation of emulsion substances in the drilling process, including sludge, brine, and oil residue contained in the drilling fluid.

ZK Oilfield Centrifuge for Drilling Mud Treatment Process

ZK oilfield centrifuge is equipment specialized in the drilling industry. Our centrifuge can effectively separate the unneeded solid materials in the drilling fluid, thereby ensuring the drilling fluid's reuse. While purifying drilling mud, it can also realize the recovery of barite. Thereby ensuring the integrity of the entire process flow and providing a guarantee for the sequence of processes. ZK oilfield centrifuges are widely used in oily sludge treatment, oily (waste) water treatment, drilling oil-based mud solid waste treatment, and three-phase oil sludge separation systems.
