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.
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.
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
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.
