Reduce the drill string and the filter cake thickness on bond issues

A mud cleaner is a combination of desanders and desilters to remove drilled solids from mud.

A mud cleaner is a combination of desanders and desilters mounted over a shaker with a fine mesh screen. A mud is fed to the inlet of the hydrocyclone (desander and/or desilter) to separate particles and the underflow passes to the fine screen mesh where in particles larger than barite are discarded and thrown away. In most drilling operations, a mud cleaner is installed in its mud systems. It is usually located in a mud tank in the same location as with the desilters.

The weighted mud flows to the inlet head section of the desander and/or desilter entering the hydrocyclones for separation of particles. Mud leaving the underflow is further screened with fine mesh to separate larger particles allowing only barite size particles to pass through the screen returning and recovering then the clean mud.

The purpose of the mud cleaner is to remove drilled solids larger than barite. Solids larger than 74-105 micrometres can be removed by the mud cleaner before the viscosity builds up. Mud cleaner can effectively control weighted drilling fluid solid content. Prevent differential pressure sticking, adhesive stuck drill accident, reduce the drill string and the filter cake thickness on bond issues.

1. Polyurethane (PU) Material for desander and desilter cones.

2. Desander cones can be installed between one and three 10”desander cones, each cone can process 500GPM and makes a separation between 40 and 100 microns

3. Desilter cones can be installed between eight and twenty 4”or 5”desilter cones ,each cone can process 80 GPM, and makes a separation between 15 and 75 microns

4. Mechanical Deck Adjustable while operation for reliable performance

5. Compact design with small footprint, with top feed and wire feed two option.

6. Hook-strip shaker screen for fast screens changing with PWP and PMD screens

KOSUN QZS series high effective mud cleaner is the second or third stage separation equipment of drilling liquid, which will deal with the mud after being treated by the first grade separation equipment. The barite will be recovered and cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the screens when the weighted mud passes while the particles that are bigger than mesh will be removed.
