How to Use Shale Shaker?

Shale shaker is a important device on the rig for removing drilled solids from the mud. This vibrating sieve is simple in concept, but it is complicated to use efficiently. Screen vibrates while the drilling fluid flows on top of it. The solids smaller than the wire mesh pass through the screen, and the larger solids are retained on the screen, and eventually fall off the back of the device, and the larger solids are discarded. Therefore, the drilling crew should seek to run the screens, the screen is fine as possible.
Where it was once common for drilling rigs to have only one or two shale shakers, modern high-efficiency rigs are often fitted with four or more shakers, give the crew the flexibility to run increasingly fine screens.

Oil Drilling Solid Control System Equipment

In general, the drilling system severed into eight blocks: lifting system, rotary system, circulatory system, transmission, drive systems, control systems, auxiliary systems.
Oil and gas drilling solid control system typically consists of the following equipment:
1. Shale shaker, can separate solid particles greater than 100 microns.
2. Drilling desander, can separate the solid phase 40-100 microns.
3. Desilter isolated 20-40 microns.
4. The drilling fluid centrifuge, can separate 2-7 microns fine particles.

The Working Principle of Vacuum Degasser

Vacuum degasser mainly made by the box, ash bucket, flow control tubes, stent filter bag and injection device, ash discharge device and other components.
The working principle of the dust collector is as follows: Dust gas enter into the filter chamber from the bottom of the open flange, coarse particles directly into the ash warehouse, dust-laden gas filter bag filter, dust resistance in the pocket table, the net by the bag to the net air chamber, then enter into the atmosphere by the fan. When the dust on the bag surface is increases, the program-controlled instrument begins to work, one by one to open the pulse valve, so that the compressed air through the nozzle on the bag to blow dust, the bag suddenly inflated, in the role of the reverse flow, giving the bag table quickly from the dust bag fell into the ash bin, dust discharged by the discharge valve.



Requirements for The Use of Mud Motor

Drilling fluid requirements, screw drilling mud motor can work effectively for a variety of mud, including oil-based mud, emulsion mud and clay mud, and even water and so on. Mud viscosity and specific gravity have little effect on the drilling tool, but have a direct effect on the overall system pressure. If the recommended discharge pressure is greater than the rated pump pressure, the mud displacement must be reduced.
The slurry pressure requirements, When the drilling tool is floating, the displacement will not change, and the mud pressure drop through the drilling tool will not change. As the bit pressure increases, the mud circulation pressure increases and the pumping pressure increases. Screw drilling mud motor is working, when the drilling pressure reaches the maximum recommended pressure, bore produces the best torque to increase the pump pressure, when more than the maximum design pressure, the motor may brake, then immediately reduce the pressure to prevent internal damage to the drill.

Sludge Dewatering Centrifuge Maintenance

We need to know how to maintain the sludge dewatering centrifuge.
First check the body parts have not slack or abnormal, when we start it and power is turned on, it must be checked that movement in accordance with clockwise. In addition, materials are placed as much as possible.

It can carry out separation, concentration and purification for different sedimentation coefficients substance by high-speed rotation. Widely used in biomedical students, petrochemicals, agriculture, food, health and other fields, it uses differences in sedimentation velocity field of centrifugal force, to achieve the separation of the sample analyzed.
The centrifuge is divided into low speed, high speed and speeding, according to type, it has horizontal decanter centrifuge and vertical decanter centrifuge. Low-speed centrifuge is mainly used for preparation of blood or cells, proteins and enzymes precipitate separation, can not generate a sufficient centrifugal force field. 

High-speed centrifuge can separate viruses, bacteria, nucleus, plasma membrane, mitochondria, and DNA preparation. 

Several Commonly Used Horizontal Directional Drilling Steering Tool

The first: dental plate drill. There are different designs for different formations. Usually used for soft to medium hardness and hardness more uniform clay or loose sand.
The second: shake roof drill bit. Shake roof drill bit is suitable for hard formations and soft rock that propulsive force can not penetrate.
The third: Whipstocking short BHA, this BHA generally used for large directional drilling through soft formations.
The fourth:Mud Motor BHA, mud motor is whipstocking tool, also is got into power tools, mainly applied to hard formations, rock formations.
The fifth: rock drill guide system. The rig has two sets of top drive apparatus, special drive drill system, BHA is very similar to mud motor, but without the drive section of the mud motor.

The sixth: Horizontal directional drilling motor DTH drilling assembly. This drill powered by compressed air, for small rigs short-range, medium-to-high hardness through rock formations, efficiency and higher compared to other tools guide.



Drilling Mud Vibrating Screen

The drilling mud vibrating screen is the main solid control equipment of drilling fluid mud recovery system. For most drilling sites, at least two drilling fluid shaker screens are used, generally need two shale shakers, while some large rigs need to be equipped with three or dynamic vibrating screen in order to meet the needs of on-site processing capacity. The vibrating screen is designed for field assembly and disassembly, rig transportation is convenient.


Mining Coal Gangue Need Shale Shaker

Coal gangue is developed by brick factory, due to environmental protection, energy saving, it has been used by major manufacturers widely. It can be used brick raw material, because the coal gangue content a certain amount of heat, can be burned and emit heat. How to filter coal gangue? Which analysis equipment does coal gangue need?
In the process of mining coal, coal gangue dug from the top of the coal seam, the bottom or carbon layer around has less carbon content. So we need some instruments to detect the best coal gangue.

We need use shale shaker, some gangue raw materials mixed with a large number of coal and coal, resulting in high heat, plasticity index is low, brick production has brought some difficulties. If we can remove these coal, on the one hand may be appropriate to reduce the heat of raw materials, improve raw material plasticity index, on the other hand, can be removed out of coal as a fuel full use. Removal of these substances must be used shale shaker.

Decanter Centrifuge Used in Chemical And Pharmaceutical Industries

Decanter centrifuge widely used in oil drilling, environmental protection and food industry, through continuous innovation, decanter centrifuge is also used in chemical and pharmaceutical industries.
In chemical production, physical separation is a very important process, solid-liquid separation of chemical fluids, the separation of different proportions of liquid, solid mixture classification, and other processes are required to achieve Decanter centrifuge. Mineral separation, such as gold, silver, lead, zinc, nickel, copper and platinum, is suitable for many different ores. shale shaker, cleaner, settling centrifuges can be widely used in the mining industry, raw materials and ore separation.

The Working Principle of Mud Agitator

Mud agitator is mainly composed of explosion-proof motor, reducer, base and pulley components, motor and reducer, reducer and the pulsator shaft are connected through a rigid coupling. The pulsator is made of four blades.
The mud agitator is suitable for the stirring of oil drilling fluid. Mud agitator in the 5.5kW following are used cycloid reducer, 7.5kW drilling fluid mud agitator using turbo worm gear drive, pulsator can make the stirring liquid vortex movement, thereby enhancing the stirring effect. The trays sandwiched of the blades also prevent sludge particles from settling around the lower blades after shutdown. This reduces the resistance of the sediment to the blades during start-up and avoids starting overload and burns out the motor.



Introduction to Fishing Tools

Fisheries production tools include a variety of gear, vessels, fishing machinery and other small production tools. The net has four types, such as ground net type, thorn net type, trawl type and foil type. 
In the fishery production, constantly update and improve fishing gear closely around the production. From manual to semi-mechanized, mechanized production, we improve the production tools to adapt to the development of productive forces.

We produce fishing tools include releasing slip spear, internal hook, releasing and circulating overshot, reverse circulation fishing magnet and others.

Length Selection of Non - magnetic Drill Collar

As a very practical measuring instruments, non-magnetic drill collars play an important role in the drilling operations. In order to ensure the accuracy of magnetic measurement instruments, the length of the non-magnetic drill collar must be chosen rationally.
The length of the non-magnetic drill collar should be selected according to the angle of the well and the azimuth angle of the well. When the angle of inclination is large, the length of the non-magnetic drill collar should be lengthened. When the center of the non-magnetic drill collars are required to use the centralizer, we must be noted that the impact of the centralizer, the best way is to make centralizer to match with non-magnetic drill collars plus steel sleeve, this can reduce the impact of magnetic measuring instruments, but also save the price of non-magnetic steel.


Application of Mud Purification System

Mud purification or mud circulation system has been widely used in various engineering fields, such as oil drilling, trenchless, coal-bed methane drilling and others. Core separation equipment for all systems is the shale shakermud cleaner, desander, mud decanter centrifuges. For different industries and fields of application, select the device type and function is different, but the principle is the same for all systems, disposal of the material will be separating the solid and liquid phases.
Mud cleaner is secondary and tertiary solids control equipment, mud cleaner combines mud cyclones, sand cyclone and underflow shaker. Mud cleaner structure is compact, small footprint, mud cleaner is the ideal choice for efficient drilling mud cleaner equipment.
