The important role of drilling fluid shale shaker in solids control equipment

The drilling fluid shale shaker is the primary processing equipment in the solids control system. It is used to separate the relatively large drilling cuttings in the mud and plays an important role in maintaining the performance of the drilling fluid. In order to ensure the production of high-quality drilling fluid shale shaker with high mud screening accuracy, low energy consumption and no dust pollution, every quality control in the production process is strictly controlled.

Outstanding performance of drilling fluid shale shaker in solids control equipment:

1. Choose a screen with large screening area, large processing capacity and good processing effect;

2. The whole screen box is heat treated, and the surface has a heavy-duty anti-corrosion coating to ensure the long service life of the shale shaker;

3. The electrical control cabinet with thermal relay overload and phase loss protection is adopted to ensure the safety of operators;

4. Adopt full-bonded ditch-edge rigid screens, which are fixed by the plate type, which makes the replacement of the screens more convenient and quick, and can replace a variety of shale shaker screens;

5. Reasonably design the height of the cofferdam of the vibrating screen logging tank to buffer and even flow the mud, reduce the direct impact on the screen, and effectively extend the service life of the screen;

6. It adopts the Italian joint venture vibration motor, which has the advantages of high vibration intensity, large screening area, adjustable screen box angle, low noise, excellent performance and high efficiency.

The key points of the design of mud agitator

The mud agitator has a sturdy structure and a compact size. The aspect ratio of the mud agitator is approximately 1:1, so the center of gravity is low and the stability is good. When the impeller encounters an instantaneous impact load, it is safer.

Because the mud agitator is equipped with a simple and high-strength unipolar worm gear reducer, it runs smoothly and evenly. The ability of the worm gear to withstand shock and vibration is more than 50% higher than that of the helical gear two-stage reduction gear of the corresponding specification. When the speed ratio reaches 60:1 and 80:1, the efficiency of the turbine transmission is lower. However, the reduction ratio of the new worm gear transmission is 20:1. Practice has proved that it has extremely high efficiency and shows the advantages that other types of gear transmissions do not have.

In order to make the mud in the mud tank agitate uniformly, according to the liquid flow spectrum, it is proved that when the blade of evil theory is inclined at 60 degrees, the axial and radial flow are equal. When the liquid touches the leaf, it is forced to move down to the bottom of the pot, and then back up along the tank wall. This movement continuously mixes the mud at the top and bottom so that the mud in each part of the tank has the same concentration. When the mud is pumped into the well, it helps to eliminate operational difficulties caused by uneven light and heavy mud.

However, most mud agitators are recommended to install impeller blades with a 60 degree inclination angle. The user’s experience proves that this kind of agitator can mix very uniformly within its applicable range.

Cyclones can be divided into three types in Solids Control Equipment

According to different diameters, cyclones can be divided into three types: desander, desilter and micro cyclone:

1. Desander: The cyclone with a diameter of 150~300mm is called a desander. Its ability to process drilling fluid is generally not less than 20~120mm³/h when the input pressure is 0.2Mpa. The desander in the normal state can remove about 95% of the drill cuttings larger than 74 μm and 50% of the drill cuttings larger than 44 μm. When selecting a desander, its allowable processing capacity should be 1.25 times the maximum displacement during drilling.

2. Desilter: a cyclone with a diameter of 100~150mm is called a desilter. When the input pressure is 0.25Mpa, its processing capacity is not less than 10~15m³/h. The desander under normal working condition can remove 95% of the drill cuttings larger than 44 microns and 50% of the drill cuttings larger than 15 microns. The permitted processing capacity of the desilter should be 1.25 to 1.5 times the maximum displacement during drilling.

3. Micro cyclone: a cyclone with a diameter of 50mm is called a micro cyclone. Its processing capacity is not less than 5m3/h when the input pressure is 0.25Mpa. The separated particles range from 7 to 25 microns. Mainly used for non-aggravated drilling fluids to remove ultrafine particles.

Cyclone is the key to solids control equipment mud cleaner and desander. Understanding the classification of cyclones can make a better choice of mud treatment equipment.

The composition of trenchless mud recovery system

The standard trenchless mud recovery system consists of mud recovery equipment, mud mixing equipment and mud collection tanks. Unlike the mud recovery device in the oil and gas drilling industry, trenchless drilling first discharges the mud back to the mud pit on the ground, and then uses a vertically installed submerged mud pump to transport the mud to the mud recovery system. Most drilling rigs will use a three-stage Purification system, shale shaker, sand removal, mud removal, and gradual removal of rock debris and solid waste. If there is a higher separation requirement, we will add a centrifuge to the system as a fourth-level processing equipment that can control the solid particle diameter of the slurry to 5-10 microns.

KOSUN has extensive field experience and a strong R&D and production team in the field of solids control systems such as trenchless mud recovery system. According to our country’s current municipal non-excavation technology and mud application status, combined with foreign advanced technology, the mud treatment equipment is optimized to ensure the completion of mud purification and recovery treatment while maximizing the protection of the original mud performance, saving construction costs, improving construction progress, and reducing Construction resistance and risk to achieve the best treatment effect.

Shale shaker, Rotary separator and Centrifuge in shield slurry separation system

In the construction process of the shield machine, the separation of slurry is an indispensable process. The separation efficiency also affects the tunneling efficiency of the shield machine. General slurry separation equipment includes shale shaker, rotary separators, centrifuges, filter presses, etc.

Centrifuge: The commonly used centrifuge is composed of two coaxial parts rotating around a static chamber. It is very effective for purifying bentonite mud, only keeping 6μm particles in the mud. Centrifuge is one of the very important solids control equipment.

Shale shaker: For the separation of materials of different particle sizes and gradations, the mud Shale shaker is the most basic solids control equipment. The Shale shaker is composed of one or more sieve plates, and the sieve hole of each sieve plate is gradually reduced. Shale shaker are generally used for sieving coarse materials, with holes as small as 60μm.

Rotary separator: The rotary separator is composed of a fixed cone. Its feed inlet is close to its shell. There is an upper overflow outlet at the top of the cone and a lower overflow outlet at the bottom. Larger speed is pumped into the rotating cone, causing it to produce a vortex, and the slurry enters the spiral in the cone. Large-sized and heavy-weight particles are separated by centrifugation at a certain speed, concentrated on the inner wall of the cone, and finally discharged through the bottom outlet; fine particles, retained in the muddy water, are discharged from the upper overflow through the spiral body. Rotary separators are widely used in surface separation stations. They can separate sand and sludge from waste mud water, and can even effectively separate 10μm particles.
