The VC700 cuttings dryer produced by Xi ‘an Kesun is used to reduce the operator’s total drilling fluid cost and limit the amount of waste disposal.

The VC700 cuttings dryer is used to recover drilling fluid directly from cuttings and weight mud from the shaker mesh to avoid loss of weight mud due to shaker failure, rig movement, or screen blockage. The VC700 cuttings dryer helps meet certain cuttings liquid discharge requirements and automatically controls the feed for solid-liquid separation. The cuttings dryer is used to recover the liquid phase drilling fluid from the cuttings by applying a high centrifugal acceleration force to the cuttings to improve the separation of liquid from the cuttings. The VC700 chip dryer can help save money on expensive drilling fluids by further purifying the expensive liquid phase that can be returned to the mud system in use.

The VC700 cuttings dryer system recovers lost mud and returns it to the in-service mud system. For diesel, mineral oil, and synthetic oil base mud, the recovery system can work well. Because it is easier to separate oil from large drill cuttings, the cuttings dryer proved to be more effective for the synthesis of oil-based mud. Synthetic oil-based mud systems also have a higher mud value, making the machine more attractive from an economic point of view. In addition, the system reduces the amount of waste and disposal costs incurred on the rig site.

Drilling cuttings dryer is widely used in drilling cuttings drilling fluid recovery, recovery of cuttings which have reuse value of drilling fluid, to reduce the cost of drilling fluid in the drilling process, and can meet the transportation and environmental protection standards of drilling cuttings, drilling cuttings dryer in the process of use in addition to routine maintenance, but also pay attention to the maintenance and maintenance of the wearing parts of the dryer. The wearing parts of the dryer include a sieve basket, scraper, sieve basket scraper, bell jar, belt, and so on.

During the maintenance and inspection process, the wearing parts of the drying machine will inevitably involve disassembly. During the disassembly process, it is necessary to pay attention to the prohibition of hammering the parts with tools such as hammers, and the prohibition of using tools such as screwdrivers to separate the fitting surface of the two parts and destroy the fitting gap of the parts. The disassembly tools or drawing tools on the parts must be used to disassemble the parts. Mark the parts before disassembly to prevent errors during installation. During the installation process, the environment should be kept clean, and all disassembled parts should be cleaned to prevent harmful substances such as debris on the parts from affecting the installation accuracy. When installing, check whether the fitting surface of the parts meets the requirements.

In the process of use, we should pay attention to check whether the following wearing parts are worn, 1, sieve basket, solid particles in the mud are screened through the sieve basket gap, with the increase of working time, the sieve basket gap will increase, when the sieve basket increases to 0.75mm, there will be a coarse phenomenon, the need to replace the sieve basket; 2, scraper, regularly check the wear of the scraper, timely adjust the gap between the scraper and the sieve basket, keep between 0.5~0.75mm; 3, screening blue scraper, must be regularly checked wear, such as serious wear need to be replaced in time; 4, the bell jar periphery or shoulder wear is relatively large, so it needs to be checked frequently, such as serious wear needs to be replaced immediately; 5, the belt should be regularly checked whether there is wear and tightness is appropriate, such as wear need to be replaced in time, the tightness is not appropriate to adjust in time to prevent affecting the normal operation of the equipment.

The centrifuge is commonly used equipment in drilling solid control system and mud non-landing system, so what is the difference between the centrifuge in drilling solid control system and the mud non-landing centrifuge?

Drilling fluid centrifuge
Centrifuge in solid control system of drilling

The centrifuges in the drilling solid control system generally use medium-low speed centrifuges. Because the drilling solid control system uses multi-level solid control equipment, when the drilling fluid is filtered and separated from the mud vibrating screen to the true separator to the sand and mud removal machine, the mud particle size has become very small, and the configuration requirements of the centrifuge have become smaller. Medium and low speed centrifuge has been able to meet the needs of mud pulping.

Mud does not fall in the centrifuge system

Centrifuges in mud non-landing systems generally use high-speed centrifuges, or variable frequency centrifuges, which belong to high configuration centrifuges. The mud non-landing system is composed of drilling cuttings drying machine and high-speed variable frequency centrifuge. The mud non-landing system is located at the end of the solid control system to deal with the drilling cuttings tail slurry after the solid control system, so the drilling cuttings tail slurry has a large proportion and the solid particle size is large. Since the centrifuge is to undertake the mud after the drilling chip dryer treatment, the particle size of the mud screened by the drilling chip dryer is very large, and the requirements for the centrifuge are very high. Therefore, the use of high-speed variable frequency centrifuge is more appropriate.

The above is the difference between the centrifuge in the drilling solid control system and the centrifuge in the mud.

After the oil-based mud returns from the well through the vibrating screen, the mud liquid phase enters the circulation system for continued treatment and use, the mud solid phase enters the filter dryer (filter separator) rock chip dryer through the screw conveyor, after the filter dryer separation, the mud solid phase is taken into the rock chip box by the screw push, the mud liquid phase flows into the liquid storage tank is pumped into the vertical centrifuge for secondary treatment. The liquid phase of the mud enters the circulation system, and the solid phase of the mud is pumped into the cuttings box through the screw pump.

In the secondary treatment, the selection of a centrifugal separator must be based on the size and concentration of solid particles in the suspension, the density difference between the solid and the liquid, the viscosity of the liquid, the characteristics of the filter slag, and the separation requirements for a comprehensive analysis, the initial selection of which type of centrifugal separator. Generally, for suspensions containing particles with a particle size greater than 0.01mm (the maximum screen mesh number for the platform is 320 mesh, and the particle size is about 0.044mm), filter centrifuges can be selected; For fine particles or compressible deformation in suspension, sedimentation centrifuge should be chosen; This is also the basis for determining the position of the drill chip dryer and centrifuge in the process. At the same time, due to the suspension of compressible deformable filter slag, under a certain separation factor, the gap between the filter slag layer and the filter medium will be blocked, and the centrifuge-treated cuttings can not pass through the cuttings dryer again.

The cuttings dryer is designed to reduce the operator’s total drilling fluid cost and limit the amount of waste handled.

The VERTICAL CUTTING DRYER is used for the reduction and recycling of drilling waste to reduce the operator’s drilling fluid cost. The dryer is a continuous screen-type vertical centrifuge, which can automatically control the feed and is used for solid-liquid separation. The dryer is used to recover liquid phase drilling fluid from drilling cuttings. By applying high centrifugal acceleration force to drilling cuttings, the effect of separating the liquid phase from drilling cuttings is improved. The expensive liquid phase in the mud system is recovered through further purification treatment. For diesel oil, mineral oil, and synthetic oil base mud, it can work well. Because it is easier to separate oil from large drilling cuttings, it is more effective for the synthesis of oil-based mud. Synthetic oil-based mud systems also have a higher mud value, making the machine more attractive from an economic point of view. In addition, the system reduces the amount of waste and disposal costs incurred on the rig site.

The Vertical Cuttings Dryer working principle:

Feed is fed from the top of the machine via a feed funnel, accelerated to machine speed by thrusters and scrapers, and sent to the screen surface. When the feed touches the screen surface, solid-liquid separation begins immediately. The flow rate on the screen is controlled by the speed difference between the propeller and the screen, as well as by the scraper blades, which stir and flip the solid phase at the same time, further facilitating separation. The solid phase is discharged at the bottom of the screen and falls into the discharge zone of the machine under the action of gravity. The solid phase is then collected through a funnel or other conveyor system placed under the machine. The liquid phase falls into the flow path through the screen and is discharged through the liquid phase outlet.

Cuttings dryers are designed and manufactured to work safer. For maximum safety, this large high-speed rotating machine requires maintenance and maintenance. Unsafe practices in maintenance and operation can endanger people and property.
