Mud gun is another equipment for agitating drilling mud or fluid during mud process. It is mounted on mud tanks. DC Machinery 2 models of mud guns 2″ and 3″.

For many years, mud guns were used as the sole means of agitation. These devices usually carry mud from a down stream comapartment and spray it into an up-stream compartment to keep solids suspended. However, the true mixing effect of mud guns tends to be localized around the point where the nozzle may add 100-200 GPM of mud into the tank above and beyond the normal flow from the well.

Parameters of drilling mud gun system

Because most systems use low pressure mud gun, correct selection of centrifugal pump and pipeline system is very important. For a low pressure system, to make it work, we must consider the following points:

(1) The size and type of the nozzle;

(2) The number of elbows, three links, valves and tubes;

(3) The length of the pipe;

(4) The size of the pipe used.jnq-80-mud-gun

These parameters are very important, in the choice of pump, the impact of each parameter must be calculated. In most systems, fluid through the nozzle will loss most of the total pressure head transferred by the pump, and discharge pipe length, pipe diameter and pipe fittings need proper pump and motor. In order to achieve a given flow rate through the nozzle, it requires a specific total head to overcome the service system friction.

Talk about working process of mud gun

The mud gun is generally placed in the tank top of drilling fluid circulating tank, which is mainly divided into two types of high pressure and low pressure. The high pressure mud gun has small output volume and high pressure, which is generally feeding liquid for drilling pump. And the low pressure mud gun is generally used to supply drilling fluid for sand pump, it has big displacement and low pressure.

Main pipeline of low pressure rotary mud gun is composed of shale shaker tank, suction tank, mixing tank, reserve tank Ι and a lateral tube on the upper-frame of reserve tank Ⅱ through a union. All the discharge pipes of sand pump in the system are connected with the main pipeline and be the liquid source of low pressure mud gun, so it can make themud gun work when open any sand pump.

The low pressure rotary mud gun consists of a butterfly valve, rotary body and the gun body. The drilling fluid is supplied by sand pump, shear pump or feeding pump.


The butterfly valve control the working condition of mud gun and control the direction of drilling fluid jetted by nozzles of mud gun through the operating handle of the rotator. Nozzles of mud gun jet drilling fluid, dash and stir the useful solid phase particles in drilling fluid deposited on the bottom of the tank.

The high pressure mud gun is fed by slurry pump, the suction tank, mixing tank and reserve tank Ι and reserve tankⅡ are separately configured with separate high pressure mainfold. Between the tank is connected with FIG1502 union and high pressure hose, each warehouse is equipped with a high pressure mud gun which is controlled by high pressure mud gate valve.

The sepecifications of high pressure mud gun: 2″/5000psi, when the oil-based drilling fluid is used by the system, the shear dilution of the mud is very poor, at this time we need to use the high pressure mud gun whose power source is slurry pump to dash and stir it, so as to mix the drilling fluid evenly.

The parameters of mud gun produced by DC Machinery

The correct choice of centrifugal pump and piping system is very important because most system use the low pressure drilling mud gun. It should be emphasized that, for a low pressure system, to make it work, must consider a few points followed:


(1) The size of nozzle;

(2) The number of the elbow, valve and tapered pipe;

(3) The length of pipe;

(4) The size of the pipes that are used.

These parameters are very important, before chosing a pump, the influence of each parameter must be calculated. In most system, when the fluid flow through the nozzle, it will lose most total head pressure transmitted by the pump, and discharged pipeline length, pipe diameter and pipe fitting all need the suitable pump and motor. In order to achieve a given flow velocity through the nozzle, a specific total pressure head is required to meet the firction force of the system.

DC Low pressure drilling mud gun

Low pressure mud gun requires about 23 meters of pressure head in normal work, the nozzle size ranges from 12.7 millimeters to 25.4 millimeters. Centrifugal pump pressurizes to nozzle through standard wall pipeline, the low pressure system does not need special thick wall pipe connection. But the variable flow velocity and the pipe with large diameter can be used to prevent excessive friction loss, the nozzle of low pressure mud gun is aslo larger than the high pressure mud gun. When a large number of liquid enter into the drilling mud tank through the nozzle of the low pressure drilling mud gun, the drilling fluid is stirred then. The liquid has a certain speed after being through the nozzle. Thereby providing the shear force which is known as the high –flow and low-pressure system.


No matter what kind of system, it shlould avoid the feeding pipeline of nozzle from being excessive bending or too long whether in economics or functions , this point is aslo very crucial for the effective operation of the equipments especially for the low pressure system.

From the bernoulli principle we can know that nozzle size and feed pressure determine that at what speed will the fluid flow through the nozzle. And at the same time, the more fluid flow through the nozzle, the larger flow rate is and greater the shear force generated. Some multi nozzle structure drilling mud gun used in the compression system can get four times liquid flow of the conventional nozzle that it can be very good in completing the mixing and diffusion of drilling fluid.

The nozzle of mud gun generate low pressure area around the area that the nozzle released, and the low pressure area is quickly sucked around the nozzle and is wrapped in liquid, which is similar to the effect of the emixing hopper. The two fluids are mixed in the funnel portion to flow into the storage tank at the slightly higher rate than te nozzle. The high speed fluid that comes out of the ejector can both come from the storage tank or other places (such as the mixed slurry tank).

mud gun choice in drilling fluid

Along with the development of drilling technology, drilling fluid solids control system for drilling operation plays positive role is more and more big, all kinds of solid control system arises at the historic moment, regardless of the solid control system model how to change, its basic functions (namely maximization removal of drilling fluid solid and store enough drilling fluid) time invariant, it depend on mechanical removal equipment and drilling fluid storage tanks of auxiliary equipment such as organic combination to complete basic function.

Mud gun (mud gun) mud gun role depend on gun nozzle produce high-speed flow, impact drilling fluid tank bottom sediments of the solid phase make its suspension. At the same time, when agitator stop after period of time, deposition of solid phase bury impeller and need to restart, mud gun work can eliminate agitator activated when the part resistance moment, it is for the normal work of the stirrer provides a reliable guarantee.

Gun drilling fluid with high, bottom pressure of points, high pressure gun by drilling pump discharge discharge tributary feed liquid, pressure rating for 4 to 6 million mpa; Low pressure gun by centrifugal sand pump feed liquid, the pressure level is 0.2 to 0.3 million mpa, configuration how much should be based on stirrer quantity to decide.
