Mud-flow device, manufactured for Russia clients

Mud-flow device, also called a jet hopper, Mud hopper is an accessories part of drilling fluid circulation system. Meanwhile mud hopper is an important part in jet mud mixer for increasing the liquid in the tube shear force, improving the dispersion effect. DC Solid control company manufactured 4 sets mud hopper for our repeat Russian clients.

hopper

The mud hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle (jet)  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.

mixer

DC’S Mud equipmet range of mud mixing hoppers delivers safe, accurate and reliable mud mixing for both on- and off-  shore applications. Design of the hopper is focused on key safety and usability features such as dust-free operations, interfacing abilities and remote or manual control options.

DC Company can also design and manufacture upgrades of existing mud mixing hopper systems to ensure dust-free
operations and more modern interfacing abilities. Feeding and dosing is controlled using Open / Close valves; the valves can be controlled remotely (optional) or locally.

Maintenance of Jet Mud Mixer

jet mud mixers

In order to make the installation and operation of jet mud mixer to be more efficient, attentions should be paid to the following questions:

1. Select jet mud mixer that suitable to drilling fluid solid control system. Normally, to most solid control system, a mixing hopper is just enough, if the drilling fluid circulation rate is bigger than 4550L/min, consider using a capacity of 4550L/min mixing hopper.

2. Keep the distance of line pipes and mixing hopper as short and straight as possible. Selection of pump and motor should based on the system requirements of pressure head and flow rate. During all operation, Venturi tube can play a good role, especially when the system back pressure will reduce the drilling fluid mixing hopper working efficiency, venturi tube allows fluid to move to higher height than the hopper in the vertical direction, in many cases, mixing hopper is placed in horizontal direction, while the downstream pipeline is placed higher or equal to the height of the drilling fluid tank top.

Why we should install Jet Mud Mixer correctly?

Why the installation of Jet mud mixer is very important? 

Jet mud mixer can work effectively, but the jet mud mixer unreasonable installation will cause a lot of problems.

The low add speed will increase the drilling time and the time of processing drilling fluid. If the mixture discharged from jet mud mixer enters into the tank which no suitable agitator device, even if the hopper disperses and wetting material fully, also can make a lot of solid particles precipitate.

If we can choose, install and debug charging system correctly, the work load of whole system maintenance will be reduced, the drilling fluid cost will be decreased, the working hours of treating drilling fluid also will be reduced.

How to install and choose the Jet mud mixer correctly?

1 Need to satisfy the requirement of proportioning at scene. 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.

 

 

High quality Jet Mud Mixer for sale

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. If put them directly, the materials of drilling fluid and chemical additives will be deposited largely or dump together and we can’t obtain diffused and well-proportioned drilling fluid.

Several days ago, we supplied a jet mud mixer for our customer. The following is the technology parameters:

1 Matching pump: 22Kw

2 Treating Capacity: 100m3/h

3 Pressure: 0.25~0.40Mpa

4 Inlet: 35mm

5 Hopper dimension: 600x600mm

6 Burden speed: ≤100kg/min

7 Density: ≤2.8g/cm3

8 Viscosity: ≤120s

DC Machinery can design and manufacture high quality jet mud mixer according to the requirement of customer. Welcome to our website.

 

Detailed installation of Jet mud mixer

As with all equipments, jet mud mixer  must be correctly  calibrated and installed, to obtain the ideal working performance.

1 Try to reduce pipeline on-way resistance, thus the pipeline required short and thick, smooth bend. Jet hopper equipped with matching venture tube can improve treating capacity, speed up solid diffusion and avoid caking.

2 The return pressure of outlet pipe needed moderate, overlarge return pressure will reduce the treating capacity of mixed hopper. For example, when the nozzle outlet diameter is 50mm, the gap between nozzle and venturi tube is 90mm, mixed hopper working pressure head is 21~23m, before return pressure value not reach 50% of inlet pressure, mixing chamber has the high vacuum, however when the return pressure value is near by 50% of inlet pressure, the vacuum is almost zero, drilling fluid begin to return flow in hopper.

3 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.

4 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.

Especially when happen to blowout, you need to confect and make up weighting material evenly at short notice, so the equipment must be used. Jet mud mixer is a kind of equipment which matching with petroleum drilling solids control system, using it to satisfy drilling fluid of weighting and preparation.

Jet mud mixer device generally consists of a sand pump and a jet flow mixed funnel 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 funnels called double jet mud mixer device.
