The role of oil solids control centrifuge in the drilling industry

Explore the role of oil solid control centrifuge in the oil drilling industry.

In the oil and gas drilling industry, solids control equipment plays a vital role in ensuring the efficiency and safety of the drilling process. One of the key pieces of equipment in a solids control system is the centrifuge. Oil solids control centrifuges are specifically designed to separate solids from drilling fluids, also known as mud, to maintain the required properties of the mud and prevent environmental pollution.

oil solids control centrifuge

 The working principle of a centrifuge is to use centrifugal force to separate solids from liquids. When drilling fluid enters the centrifuge, it spins at high speed, causing solids to be forced to the centrifuge walls while cleaning fluid is discharged through the top. This process continuously removes solids from the drilling fluid, ensuring that the drilling fluid remains in optimal condition for efficient drilling operations.

The petroleum industry uses different types of centrifuges, including decanters and vertical cuttings dryers. Decanters are typically used to remove fine solids from drilling fluids, while vertical cuttings dryers are designed to separate solids from drilling waste cuttings produced during the drilling process.

The importance of oil solids control centrifuges in the drilling process cannot be overstated. Without effective solids control, drilling fluids can become contaminated with solids, resulting in reduced drilling efficiency and potential damage to drilling equipment. Additionally, improper management of drilling waste can lead to environmental contamination, resulting in costly cleanup efforts and potential legal consequences.

In summary, oil solids control centrifuges are critical to maintaining the integrity of drilling fluids and ensuring the success of drilling operations. By effectively separating solids from drilling fluids, centrifuges play a key role in optimizing drilling efficiency and minimizing environmental impact. As technology continues to advance, the development of more efficient and effective centrifuge systems will further enhance the role of solids control equipment in the petroleum industry.

Composition and Development Trends of Drilling Fluid Solid Control Equipment

The performance and quality of drilling fluid solid control equipment are crucial for solid control technology. The drilling fluid solid control system mainly consists of drilling fluid circulation tanks, drilling fluid purification and treatment equipment, and electrical control equipment. The drilling fluid purification and treatment equipment mainly includes shale shakers, desanders, desilters, degassers, centrifuges, sand pumps, agitators, and mixers. For environmentally sensitive areas, drilling cuttings recycling and waste liquid treatment devices can also be configured.

Development trends of drilling fluid solid control equipment:

Currently, there is a focus on developing compact, high-efficiency, and long-lasting equipment such as desanders, desilters, and degassers. Integration with high-speed centrifuges is also being pursued to achieve automatic detection and control of solid control systems based on test results.

Status of drilling fluid solid control equipment overseas:

Solid control equipment overseas has good performance, stable operation, and long lifespan. It has achieved standardization, serialization, and specialization of equipment types. The solid control equipment level overseas is represented by companies such as BRANDT, SWACO, and DERRICK in the United States, which are at the forefront in terms of quality and performance. Foreign countries pay special attention to optimizing the configuration of solid control system equipment and evaluating the efficiency of the entire solid control system. They have developed expert systems for drilling fluid solid control.

The solid control system of the American Petroleum Tools Company consists of four shale shakers and two dryers (dry vibrating screens). The four shale shakers and one dryer are connected in parallel. The drilling fluid returned from the well is divided and sent to the four shale shakers and one dryer for processing. The separated solid particles are further dehydrated by another dryer. The recovered liquid is discharged, and the dried particles are discharged.

The dryer is actually a high-intensity fine-mesh shale shaker with a 10° inclined screen frame to reduce liquid loss. The screens used in the four shale shakers are three-dimensional fine-mesh wave-shaped screens, not traditional flat linear screens. The three-dimensional structure allows gravity to force incoming solids downward into the crevice and leave the raised area, separating solids from the upper part of each fold. This increases the amount of fluid passing through without submerging the raised part, while the raised part enhances fluid flow. Two layers of fine screens are attached to one layer of coarse screen, and the three layers of screens are bonded together in a corrugated shape, and then glued to the perforated plate. The combined waveform screen area is approximately 40% larger than that of a regular flat screen, with fineness approximately 2-3 times larger than that of a flat screen. It has a 70% increased fluid handling capacity and is less prone to blockage, providing excellent processing effects.

Development of domestic drilling fluid solid control equipment:

In recent years, there has been significant progress in the theoretical research and manufacturing process of domestic drilling fluid solid control equipment, especially in theoretical research on the working principles of vibrating screens and cyclones, which have reached or approached the world’s advanced level. However, there is still a gap between domestic solid control equipment and foreign equipment in terms of performance and lifespan, mainly due to the quality of materials, processing technology, processing accuracy, and the quality of commonly used equipment such as motors. High-pressure (withstanding 80MPa) and high-displacement (30L/s) solid control equipment are not yet available domestically. There are fewer types of shale shakers domestically, and efforts need to be made to accelerate the development of dry fine-mesh vibrating screens, track-mounted non-vibrating screen analysis equipment, environmentally friendly dedicated solid control equipment for offshore drilling, and versatile solid control supporting systems suitable for various working conditions to enrich the types of solid control equipment in China.

The drilling fluid vacuum degasser is a new special equipment for treating drilling fluid with gas invasion

Xi ‘an KOSUN VD series drilling fluid vacuum degasser is a new special equipment developed by our factory on the basis of comprehensive degasser at home and abroad. It is suitable for all kinds of mud purification systems, which play a very important role in restoring the specific gravity of mud, stabilizing the viscosity of mud, and reducing the drilling cost. At the same time, it can also be used as a high-power agitator.

KOSUN drilling fluid vacuum degasser

The degasser belongs to the drilling fluid vacuum degasser, that is, the suction effect of the vacuum pump is used to create a negative pressure zone in the vacuum tank. Under the action of atmospheric pressure, the mud enters the hollow shaft of the rotor through the suction pipe and then is thrown towards the wall of the tank in a spray shape through the window around the hollow shaft. Due to the impact of the collision and the separation wheel, the drilling fluid is separated into thin layers, and the bubbles immersed in the mud are broken. The gas escapes through the suction of the vacuum pump and the separation of the gas-water separator, the gas is discharged to the safety zone by the exhaust pipe of the separator, and the mud is discharged from the tank by the impeller. Since the main motor starts first, the impeller connected to the motor is in a high-speed rotation state, so the mud can only enter the tank from the suction pipe, and will not be sucked from the drain pipe.

Last week, our factory shipped 8 pcs of drilling fluid vacuum degassers to foreign countries. As supporting equipment of drilling solid control equipment, this equipment provides a safety guarantee for drilling.
