Mud mixing hopper for solids control system

2012-12-14

Mud mixer widely used in HDD(horizontal directional drilling) and oil gas drilling. Jet mud mixer device generally consists of a sand pump and a jet flow mixed hopper with manifold valve connection and are installed in a pedestal called the single jet mud mixer device, or by two pumps and two mix slurry hoppers called double jet mud mixer device.

 

Jet mud mixer is used to make up drilling fluid or increase total amount of the drilling fluid, change the fluid density, viscosity, and dehydration. When making up again, put the materials of drilling fluid (such as betonies and barite powder) and corresponding chemical additives (such as polymer) into the recycle tank through the jet unit.

 

Mud mixing hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle below the conical-shaped hopper. Dry materials are added through the mud hopper to provide dispersion, rapid hydration and uniform mixing. Liquids are sometimes fed into the mud by a hose placed in the hopper.

 

Need to satisfy the require of proportioning at scene. General requirements mixing hopper capacity shall not be less than150m3/h. For the larger tank and great pump motor power, we can also use the mixing hopper with300m3/h capacity.

 

In order to ensure the required well pressure, suggest that each drilling crew should equipped with a spare set of mixing hoppers, in most cases spare hoppers used overlap mode.
