The first part for jet mud mixer– Centrifugal Pump

Centrifugal pump is the fluids supply for drilling mud mixing hopper. The pump size will be selected depending on mixed mud specification and mud flow mixing requirement. The centrifugal pump will work to transfer water or drilling mud with a suitable pressure. Other than supply drilling mud to mixer hopper, the centrifugal pump can work as feeding pump for desander & desilter, trip pump for trip tank, water pump for water line supply, etc.

The second part for jet mud mixer– Mixing Hopper

Mixing hopper will work to collect drilling chemicals with a small table for operation. The drilling chemicals will goes into hopper together with water or drilling mud supplied by centrifugal pump.

Jet mud mixer is a new type of mixer which consists of feeding hopper, butterfly valve,mixing barrel, floe meter, vortex volute and large displacement of  centrifugal pump.

The sand pump pumps the liquid that need to be mixed into the swirl volute along the tangential direction, high-speed rotation liquid in the volute creates a vacuum which inhales the mixed materials and then enter into the mixed tank after being blended with the high –speed rotation liquid. High –speed rotating liquid flow will blend the materials with the fluid fully in the inner cavity of the mixing barrel, after that they go into the outer cavity of the mixing barrel of the swirl mud mixer and then discharged along tangent direction, then the mixing process of a periodic cycle is completed.

The jet mud mixer has the following characteristics:

Long effevtive mixing time and better mixing effect; the feeding caliber is large so it is not easy to be blocked, the feeding speend of the jet mud mixer is fast and it has strong adastability fo materials. It has the wide application and will not extend the time to stop so that the phenomenon of solid phase deposition will not occur.

The factors that will influence jet mud mixer

Jet mud mixer is usually composed of one set of centrifugal pump and a set of jet mixing hopper, which is connected by pipe manifold valve to install on single jet mixing device that is composed of a base. Or two sets of pumps and two sets of mixing hopper composed a double jet mixing pump.

Generally speaking, if want to enhance treating capacity, we can depend on increasing work pressure and changing a larger spray nozzle to realize. And experiments show that increasing the nozzle diameter and inlet flow rate is a more economical method.

Main factors affecting on jet mud mixer performance
1. Reduce hydraulic edge of mixing hopper loss as far as possible, or may lower treating capacity greatly.

2. The distance from pray nozzle to venturi tube should be suitable, the best distance is to keep at 32-90mm, usually can’t exceed 90mm, otherwise, the feeding speed of barite will be decreased significantly.

3. The back pressure of the outlet pipe should be suitable, the larger back pressure will reduce the processing capacity of the mixing hopper.
For example, when the nozzle outlet diameter is 50mm, the gap between the nozzle and the venturi tube is 90mm and the working pressure head of the mixing hopper is 21-23m. The mixing chamber has a high vacuum value before the pressure value is reached 50%. But when back pressure close to the inlet pressure 50%, the vacuum degree is almost zero and drilling fluid start back-flow in the hopper.

4. The larger inlet pressure, the larger treating capacity of mixing hopper.

5. The higher for mixing hopper installation, the higher back pressure and mixing ability will be decreased.

When configuring or increasing the total amount of drilling fluid, change the density, viscosity and water loss of drilling fluid, it all need to put the drilling fluid materials (bentonite, barite powder, etc.) and the corresponding chemical additives (polymers) into the circulation tank. The jet mud mixer can increase the shear force of the liquid in the tube, and to increase the material dispersion effect better, improve the pressure head of mixing liquid, so that the material in the tank is fully mixed and circulated, and the use effect will be more outstanding when supporting the use of shearing pump.

Jet mud mixer is a device that supporting the use of oil drilling solid control system, which can meet the requirements of the aggravation and configuring of drilling fluid of different depth of drilling fluid solid control system. The mixed slurry device consists of one  (or more) sand pump and one  (or more) jet mixing funnels which is connected by pipe manifold valve and installed on a base. The funnel and sand pump can be combined or installed splitly, and between the aggravating funnel and the sand pump is the pipe valve connection.

Jet mud mixer is a specialized solids control equipment used for configuring and aggravating drilling fluid, thus change the density, viscosity and pH of drilling fluid.

DC uses venturi tube combined with original jet nozzle created a new design of jet mud devices, it is not only simple in structure, but also have strong feasibility, which can meet the requirements of aggravation and configuration of drilling fluid in drilling solid control system from 1500m to 9000m. We can also produce double jet mud mixers according to customers’ requirements.

Jet mud mixer produced by DC have the advantages of high mixing speed, safe and reliable performance, long service and etc.

How to make good condition of jet mud mixer

In order to make the installation and use of the jet mud mixer more efficient, we should pay attention to several problems:

1 Selecting the  jet mud mixer which is suitable for drilling fluid system.

2 Keep the distance between the pipe line and the hopper as short and straight as possible.

3 Use new and clean spare parts to reduce friction loss.

4 Working table should be installed and fixed near the funnel to support the materials in a bag.

5 As well as the maintenances of other drilling equipments, regular maintenances and inspections of the drilling funnel shall be maintained.

If the injection function of the nozzle is not up to standard, the following contents shall be checked :

1 in normal discharged pressure head, determine whether the pump can provide enough drilling fluid, and check the pressure gauge on the upper reaches of the funnel of jet mud mixer.

2 When the device is closed, the hopper and valve are removed from the three – way pipe, and the live joint is installed on the upper of the funnel, and check to determine whether there is corrosion or whether there is an object – blocking gas lift pipe.

Detailed rules for the use of the mud mixing plant

The jet mud mixer slurry is a new type of mixer with fast mixing speed, uniform mixing and little energy consumption. It has a simple structure and convenient connection. The main purpose of jet mud mixer is to make the drilling fluid quickly and evenly mixed with its additives.

Main structure of jet mud mixing device:

Jet mixing device comprise by inlet changeful connector, nozzle, tee joint, trumpet outlet, butterfly valve, funnel etc.. High speed liquid flows with kinetic energy from the inlet changeful connector into the nozzle, the liquid jet into the tee joint at a breakneck speed, while the material added into the tee joint from the funnel, the added materials are mixed with liquid by flowing and enter into the drilling fluid system through the horn outlet.

Characteristics of jet mud mixing device:

The main features of the use of jet mud mixer device is to make the added materials (barite, bentonite, salt, mud, chemical additives, etc.) mixed with the drilling fluid fully and evenly before before entering the drilling fluid system, which improve the quality of drilling fluid, give full play to the role of adding materials, reduce the amount of material added that saves the mud cost and the feeding speed is fast, mixed ability is strong. The jet mud mixing device can also be composed of a complete shear and hydration system when used with a shear pump.
