A mud cleaner purifies mud in a drilling system by using a hydrocyclone to remove solids and a mesh to prevent larger particles from passing through. Barite can be used for drilling and larger particles are removed to prevent the liquid from becoming too thick.
A mud cleaner is a type of cleaning and purification system in a drilling system. When mud enters a drilling system, such as one used for oil drilling, it first passes through a hydrocyclone, which is the first step in purifying the mud. After the solids pass through this system, they encounter the sludge cleaner, which is a mesh that has small holes to prevent larger solids from passing through the fluid. The mesh itself is typically made to block barite, because this is a common substance used and found in drilling. This keeps the mud from getting too thick and stopping the drill, and allows the larger particles to be used for other purposes.
The first step in using a mud cleaner is to send the mud through a hydrocyclone, as it would be too thick for the cleaner to work effectively. A hydrocyclone is a device that uses force to push the purified sludge through the top section of the cyclone while the thicker particles pass through the lower section. Anything that passes through the lower section meets the mud cleaner.
While a hydrocyclone can help purify the mud to some extent, the mud cleaner is responsible for further purifying the mud. The cleaner is little more than a mesh with fine holes made for tiny particles to pass through. Anything small enough to pass through the holes meets and mixes with the purified sludge expelled by the hydrocyclone.
Larger particles are treated differently, depending on the user’s needs. The mud cleaning mesh is made to allow particles smaller than barite to pass through, and barite can be useful for some drilling processes. If the user has no need for barite, or if there are other particles that cannot be used, they are simply discarded. Barite can be used to weight down drilling solutions, and the weight can be useful in creating a stronger, more usable fluid with drilling applications for liquids or dense solids.
Regardless of the use of barite and larger particles, they are commonly removed from the drill and purification system after the mud cleaner has separated the particles. This is because large particles can cause the liquid to become too thick, meaning it will no longer be able to pass through the machine. By diluting the liquid, it is easier for the drill to continue drilling.
