Mud gun is meant to provide supplemental or primary mixing in mud tanks depending on the number being used and the pit size. They are best used in tank corners to keep solids from settling and a mud agitator is placed in the tank center. The mud gun in the mud system is also used for transfer mud from compartment to compartment, like for trip tank compartment.

 

 

Mud gun is divided into pressure mud gun and low pressure mud gun.High pressure mud gun have small output volume, big pressure, usually have a drilling pump supply liquid.

 

 

It features in simple structure, flexible operation, convenient application, making itself an ideal anti-deposition device of mud solids control system.

Linear Motion Mud Cleaner

Mud cleaner has an efficient solids-fluids processing design, which consists of a linear shale shaker, desander with two 10” cones and a desilter with twelve 4” cones primarily used to eliminate 20 – 76 microns of sand and mud in the underflow.

 

 

The drilling fluid will firstly pass the desanding cyclones or desilting hydrocyclones for separation, with overflow returning to the circulatory system and the bottom flow screened and treated by the vibrating screen. If necessary, the vibrating screen of the integrator could be used as the forestage vibrating screen.

 

 

drilling fluid desanding and desilting integrated mud cleaner, or integrator for short, is used for separating the solid-phase granules in the drilling fluid after treated by the shaker screen.

 

 

Brightway compact,multi-functional mud cleaners are designed to be operated as both a double-deck drying shaker / mud cleaner or double-deck flowline shale shaker. The built in multi-functional  feature allows the operator to handle varying drilling fluid viscosities and solids content with the same unit. In the dual simultaneous flow mode, the top deck handles the hydrocyclone underflow and the bottom deck handles the primary scalping.

Mud Agitator

Mud agitator is a part of solid control system, which is mainly used in agitating and blending drilling fluid so as to control the depositions of solid particles in its tank cycling system and keep the drilling mud property of circulation stable and mixture uniform.The drilling mud agitator are required for storage mud tanks, or mud tank with solids control equiment.

 

 

Brightway mud agitator is driven by an explosion-proof motor, coupled to a gear box that drives the impeller shaft. The impellers (turbines) transform mechanical power into fluid circulation or agitation. The objective is to obtain a uniform suspension of all solids.
BWJBQ Series mud agitator adopt mechanical seal and composed of explosion -proof motor ,speed reducer ,motor base and blade.

 

 

BWJBQ Mud Agitator adopt the turbo and worm gear-down, with the advantage of large torque transmission, smooth operation performance reliable etc. It has two kinds of installation method: horizontal and vertical.

 

 

Brightway mud agitator is part of drilling fluid solid control equipment ,which is mainly used to agitate and mix the drilling mud to prevent solid particles settlement in circulating tank.

Drilling Mud Desander

The desander is an important part of the mining and drilling process. This simple euipment helps filter out grainy solids from drilling liquid.
Brightway drilling mud desander is used as the 2nd stage of solids control for drilling mud, which makes separations between 45 and 76 μm.

Features of Drilling Mud Desander
1,Polyurethane(PU) Material or high-chromium cast iron for drilling fluid desander cones with longer using life.
2,Flexible options for 1, 2 or 3 for different capacities.
3,High mud handling capacity, sand can be removed efficiently.
4,The shaker screen has many advantages such as easy operation, low trouble rate, convenient installation and maintenance.
5,The adjustable vibrating force, angle and mesh size of the shaker enable the equipment possess a high screening efficiency in all kind of strata.
6,The high screening efficiency of the machine can excellently support drillers raise bore and advance in different strata.
7, Compact design with small footprint

 

This type of desander generally is utilized by the petroleum industry. Other industries also use desanders, mostly those dealing with drilling and mining for substances such as natural gas. Companies that manage lakes and dams sometimes use desilter and desander to pass along water and keep it free of impurities.

4. Shared sunction tank for desilter and desander:
If the mud desander  desilter share a sunction tank, then half drilling fluids is treated by desilter and another half by desander. That means, 50% of the fluids pumped into the well is not treated by desander and another 50% not by desilter, thus betraying the basic rule of successive treatment and disabling the desamder to effectively reduce the solids load in desilter.

5. Two centrifugal pumps in parallel to supply the same equipment:
It is commonplace in the configuration of solids control system because, with 30m pressure head and 25L/s funnel nozzle, two centrifual pumps installed in parallel equal to a pump with 30m pressure head and 25L/s funnel nozzle.Desilter
If the single pump does not have required pressure head of the equipment, then it is not proper to place another one in parallel, but rather to examine if it is in good condition. If it is but the pressure head is still not up to the scratch, then replace the propeller with a larger one.

Operational Details of Solids Control Equipment Part 1

It is quite essential to normally operate any solids control system or equipment in oil & gas drilling. Therefore, Brightway has summed up a list of techniques concerning the equipment operational details based upon actual operations, which will make your drillings more productive with less energy consumption.

solids control system
1. Weak capacity of solids control equipment:
It should be taken into consideration how much the fluids can be injected into mud tank according to equipment’s actual capacity and how much the flow rate is in mud agitator in order to guarantee the quality of processing the fluids.

mud cleaner

 

2. Return of the rough solids removed by shaker screen in mud cleaner:
If the liquid flow all returns to the system, that means nothing has been taken away. Thus, the solid particles left on the screen of mud cleaner ought to be removed.

vacuum degasser
3. Installation of vaccum degasser at the downstream of hydrocyclones:
If the degasser is placed behind the equipment supplied by centrifugal pump, the pump can be blocked by entraining gases. Entrained fluids will reduce its flow rate and working efficiency of hydraulic cyclones. If the gases are poisonous, it is better to remove them in the first mud tank rather than the third or the fourth one.

Mud decanter centrifuge for drilling fluids purification

Drilling decanter centrifuge is the solid control equipment of final phase. It is used after the equipment of shale shaker,  desander ,desilter, mud cleaner and other related equipment. The product can process drilling fluid of weighted type, unweighted type, water-based type and oil-based type.

 

shale shaker

By using mechanical energy to increase gravitational force up to which is applied on the solids, it can separate both heavy and fine solids from drilling fluid. When working with the other solid control equipment, the product shows great superiority in keeping proper mud weight and viscosity. Then, the drilling fluid can meet the requirements of oil drilling completely.

Ⅵ· How to Allocate the Mud Tank for the Drilling Rig.

According to its function in solid control system, the mud tanks include suction tank, agitator tank, storage tank, etc. The allocation of mud tank for the drilling rig depends on the depth of the well, and also the purification stage requirement.

 

decanter centrifuge

Normally, the first three solid control stages is completed on the tank No.1, which includes shale shaker, vacuum degasser, desander, while the fourth & fifth stages would be on the tank No.2, which means desilter &decanter centrifuge, and the main function is for the centrifuge. While the other tanks will depends on the depth of the well, but also the mud demands of the drilling technique. Normally the large type drilling rig needs over 6 mud tanks.solids control system

Mud Tank In The Solids Control System Part 3

For the third purification stage,  a centrifugal pump would be used to suck up the drilling mud into the desander, after separate & discharge the solids, and the mud would enter again down into the third compartment. And the same for the desilter. And for the fifth stage of solid control system, a vertical slurry pump would be used to suck up the mud into the decanter centrifuge from the compartment that below the desilter. After separating & discharging, the drilling mud would enter again into the mud tank. and then sucked up by the mud pump into the down hole to recycle again.
