Analysis of the basic steps of the mud purification systems

With the implementation of new environmental protection laws, the requirements for environmental protection in the oilfield development process are becoming increasingly stringent. Clean production in oilfield operations is a benchmark in the petroleum industry. During the oilfield development process, a large amount of waste mud is the main factor causing environmental pollution and is also one of the high-cost factors in oilfield operations. Therefore, it is important to purify and recycle the mud, which can not only meet environmental benefits but also generate significant economic benefits.
To meet the requirements of mud purification, the petroleum machinery industry has introduced various effective mud purification equipment and systems.
The five-level mud solid control equipment on the oil drilling platform can ensure that the platform meets the requirements for mud treatment under various conditions. The solid control equipment used in mud purification systems operations mainly includes mud circulation tanks, drilling fluid shale shakers, mud cleaners, vacuum degassers, low-speed centrifuges, and high-speed centrifuges.

Kosun mud purification systems


The mud with a large amount of harmful solid phase particles returned from the wellbore flows into the entrance of the first-stage mud purification equipment, the drilling fluid shale shaker, through the wellhead elevated mud trough with a certain slope under the action of gravity. The larger harmful solid phase particles are screened out and discharged by the shale shaker.
When the drilling fluid is invaded by gas, the purified mud obtained through the drilling fluid shale shaker enters the desanding tank of the mud purification tank. By using the suction of the degasser vacuum pump, negative pressure is created in the vacuum tank, allowing the mud to enter the degasser for separation under atmospheric pressure. The separated gas is released at the top of the derrick, and the degassed mud is driven by the rotating impeller of the discharge chamber into the second chamber of the mud purification tank. In the case of gas-free mud, the degasser can be used as a high-power mud agitator to prevent the mud in the mud purification tank from settling.
The purified mud obtained through the drilling fluid shale shaker enters the desanding tank of the mud purification tank. The mud is pressurized and enters the desander of the second-stage solid control equipment, the mud cleaner, through the desanding pump. It is separated again using the cyclone principle to remove harmful solid phase particles with a separation midpoint above 70 microns. The desanded mud is then discharged into the third chamber of the mud purification tank through the overflow pipeline of the desander. According to the overall requirements of the mud purification system, the processing capacity of the desander should exceed 125% of the normal mud circulation volume to ensure sufficient repeated purification of the mud in the purification tank and reduce the sand content in the mud.
The purified mud obtained through the desander is pressurized and enters the desilter of the third-stage purification equipment, the mud cleaner, through the desilting pump. It is separated again using the cyclone principle to remove harmful solid phase particles with a separation midpoint above 36 microns. The desiltered mud is then discharged into the fourth chamber of the mud purification tank through the overflow pipeline of the desilter.
The bottom flows discharged from the desander and desilter contain a certain amount of mud. After the two bottom flows converge, they enter the shale shaker of the combined cleaner for further screening. The recovered mud is returned to the mud tank, while the sand and mud are discharged.
Even after three stages of purification, the mud still contains a large amount of harmful solid phase particles. When the mud is in a non-weighted state, two centrifuges are used in parallel to remove harmful solid phase particles larger than 5 microns. The processed mud is discharged into the fifth chamber of the mud purification tank.
When the mud is in a weighted state, the drilling fluid centrifuge not only removes harmful solid phase particles but also removes the weighting material barite from the mud, resulting in a rapid decrease in mud density and a significant loss of weighting material. To avoid the loss of weighting material and achieve the goal of removing harmful solid phase particles, two centrifuges are used in series, with the medium-speed centrifuge as the first stage and the high-speed centrifuge as the second stage.

The weighted mud extracted from the mud tank by the feed pump of the low-speed centrifuge is processed by the centrifuge, and the processed mud enters the mud purification tank. The bottom flow (containing a large amount of barite) is discharged into the dedicated tank below the medium-speed centrifuge. It is pumped into the second-stage high-speed centrifuge for further separation. The mud containing barite returns to the mud purification tank to maintain the stability of the mud’s performance. The separated harmful solid phase particles are discharged outside the system, achieving the goal of purifying and maintaining the stability of the mud’s performance.

The specific configuration of the solid control equipment at each level will be adjusted according to the specific conditions of the operation site to achieve the best mud purification and recovery effect.

We Urgently Need Efficient Drilling Waste Management Solutions.

We urgently need efficient drilling waste management solutions.
Why was there so much waste in early oil drilling?
There were several reasons for the generation of a significant amount of waste in early oil drilling:
One of the most important reasons is the lack of technological advancements, in the early days of oil drilling, the technology and techniques were not as advanced as they are today. This resulted in less efficient drilling processes, leading to a higher volume of waste generation.
Another vital reason is inadequate waste management practices. The understanding of proper waste management practices was limited during the early stages of oil drilling. There was often a lack of awareness or regulatory requirements regarding the proper handling and disposal of drilling waste.
Due to the limited environmental regulations, environmental regulations and standards regarding waste management were not as stringent or well-established during the early years of oil drilling. This allowed for more lenient practices and less focus on waste reduction and proper disposal.
Another important reason is economic considerations, in the early days of oil drilling, the primary focus was on extracting oil as quickly and efficiently as possible. Waste management and environmental concerns were often secondary considerations, resulting in less attention given to waste reduction and disposal practices.
It is important to note that with advancements in technology, increased environmental awareness, and stricter regulations, the oil drilling industry has made significant progress in minimizing waste generation and implementing proper waste management practices.

Drilling cutting treatment equipment is the key process in the process of cutting treatment

Drilling cutting treatment equipment is the key process in the process of cutting treatment.

Drilling is a high-intensity operation that will produce a large amount of cuttings, which will pollute the environment if not treated effectively. Drilling cuttings treatment technology involves the design of a drilling fluid system, the selection of cuttings treatment equipment, and the control of the treatment process.

KOSUN drilling cutting treatment equipment

Drilling fluid is an important liquid to carry cuttings from the bottom of the well and cool the bottom of the well. The design of the drilling fluid system should take into account the drilling purpose, wall stability, cuttings suspension, pollution control, and other factors.

The purpose of drilling determines the properties and selection of drilling fluid. Different drilling purposes require different drilling fluids. For example, water can be used as drilling fluid to drill Wells, while special drilling fluids are needed to drill oil Wells. An important role of drilling fluids is to promote the stability of well walls and avoid problems such as mutual wear and soil layer collapse. The drilling fluid includes a pressure function, cuttings suspension function, anti-friction function, filtration control, mud column support function, etc. In addition to having a certain supporting effect on the well wall, the drilling fluid should also have enough suspension ability to ensure that the cuttings are taken out of the wellhead as soon as possible to avoid the accumulation of cuttings in the well. The drilling fluid contains harmful substances, which will affect the environment if the pollution is not controlled effectively. Therefore, pollution control should be fully considered in the design of the drilling fluid system.

So, drilling cutting treatment equipment is the key process in the process of cutting treatment. The selection and quantity of equipment determine the effect and cost of cutting treatment.
Therefore, when we choose drilling cutting treatment equipment, we should find a professional company, which can provide professional and economic solutions. KOSUN is a professional drilling waste treatment company, established more than 30 years, has rich experience in drilling cutting treatment.

Prominent Advantages of the Drilling Cuttings Zero-Discharge Process

The drilling cuttings zero-discharge process, also known as drilling waste management system, cuttings zero-discharge system, or drilling waste zero-discharge system, can be divided into water-based mud zero-discharge system and oil-based mud zero-discharge system according to its application.

oil-based slurry zero discharge system


With the continuous increase in environmental requirements, higher demands have been placed on drilling site cuttings treatment. The emergence of drilling waste management and purification systems not only effectively solves on-site environmental issues but also enables the secondary recovery and treatment of waste generated by the site’s solid control system. It preserves useful mud while centrally solidifying the treated cuttings, reducing the damage to the surrounding environment caused by on-site operations.
Traditional tailings treatment usually involves storing cuttings and wastewater generated during drilling in mud pits, which not only occupies limited land resources at the drilling site but also imposes economic burdens. Therefore, the update of mud treatment technology is urgently needed, and the advent of the drilling cuttings zero discharge process solves this problem effectively.
The drilling cuttings zero discharge process involves treating waste generated drilling during the drilling process, without passing through a mud pit for wastewater treatment. It is processed in real-time alongside the drilling process, achieving the integration of work efficiency, economic benefits, energy conservation, and environmental protection. In many drilling sites, this process is also known as the “drilling waste in-sync processing” technology. The drilling cuttings zero discharge process has been widely accepted and adopted in the world.
