What Need Noting During Installing Jet Mud Mixer?

In a complete solids control system, jet mud mixer is usually installed at the end, or we could say that it is a unit placed besides the mud tank and used together with the solids control system. Unlike shale shaker, mud cleaner and decanter centrifuge, it doesn’t separate the large solid particles from drilling mud. However, it is still not ignorable.

During installing drilling fluids jet mud mixer, what need us to note? The following tips may be helpful.

1. General requirements mixing hopper capacity shall not be less than 150m3/h. For the larger tank and great pump motor power, we can also use the mixing hopper with 300m3/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.

2. The return pressure of outlet pipe needed moderate, overlarge return pressure will reduce the treating capacity of mixed hopper.

3. The gap between nozzle and venturi tube must be suitable, when reach optimum efficiency, the gap is 32~90mm, usually don’t more than 90 mm, otherwise the feed speed of barite will be significantly reduced.

4. Another important consideration of install equipment is the drilling fluid required lifted height. If discharge needed to enter into different deck tank or a taunt tank and hopper, mix rate will be decreased. When the height from 1.83m to 3.66m, barite adding rate will be reduced to 17%. If the increased demand is very high, the pump capacity is insufficient, mixed ability will be greatly reduced.
