Working Mechanism of Jet Mud Mixer for Solids Control System

Aug 22, 2013

As we all know, drilling fluids is used in the drilling process to keep the drill bit cool and carry the down hole drilling cuttings up to the surface of the well. To maintain the specified viscosity and density of the drilling fluids, some drilling fluids agents such as barite, bentonite, etc. must be added into the fluids in the drilling process. Previously, the centrifuge is used to add these fluids agents into the drilling fluids, but now mud mixer or some device called mud hopper are used specially to complete the adding processing in the solids control system.

Jet mud mixer is the specialized equipment to prepare and increase the drilling fluids weight by adding and mixing bentonite, change the fluid density, change the mud density, viscosity and dehydration. The effect is more prominent if it is matched with shear pump. DJM Jet Mud Mixer is a unit used together with the solids control system for petroleum drilling and horizontal directional drilling. The unit includes one sand pump, one jet mixing hopper and one jet mixer that are installed in a base with pipe valves. It is safe and stable and can be moved conveniently.

Working Mechanism of Jet Mud Mixer

The drilling fluids flows into the jet pump with certain pressure, in the jet pump, fluids spouts out from jet nozzle first, then flows into shear pipe through mixing chamber. Materials will be added from hopper to mixing hopper, and move into shear pipe with the flow. During this process, they are dispersed and mixed. The mixture will enter mud tank after flowing out of the shear pipe.

The shear pipe is hollow and it can expand gradually based on certain curved surface. It is mainly used to enlarge shearing force inside the pipe to disperse the materials further and increase the mixture pressure head, this will make it easy to enter circulation tank.

Solids control is so indispensable in drilling that we can’t work in drilling without it . As one of the professionals in solids control, KOSUN provides all the solids control equipment, such as shale shaker, decanter centrifuge, vacuum degasser, etc. Apart from being specialized in designing & manufacturing of jet mud mixer, KOSUN can also manufacture a whole solids control system for oil & gas drilling based on the requirements of the customers.
