Separate Ultrafine Solids With LW Series Decanter Centrifuge In Oil And Gas Industry

________________________________________

Product Description:

Horizontal spiral unloading sedimentation centrifuge is a crucial fine separation equipment in the solid control system of oilfield drilling. It is mainly used to separate fine solid particles in drilling fluid. The separation particle size can be as low as about 2 microns. It plays an irreplaceable role in maintaining the stability of drilling fluid performance, improving the reuse rate of drilling fluid and reducing drilling costs. Through continuous operation, this equipment realizes efficient solid-liquid separation of drilling fluid, providing a strong guarantee for the smooth progress of the entire drilling operation.

Working principle:

The horizontal spiral unloading sedimentation centrifuge produced and sold by our company Huichi petro works based on the principle of centrifugal sedimentation. When the equipment is running, the drilling fluid is transported to the inside of the drum through the feed pipe. The drum generates a strong centrifugal force during high-speed rotation, which is usually hundreds or even thousands of times the gravity. Under such a strong centrifugal force, the solid particles in the drilling fluid quickly settle to the inner wall of the drum due to their greater density than the liquid phase, forming a sediment layer; while the liquid phase forms a clarified liquid layer in the center area of ​​the drum. At the same time, the screw conveyor, which rotates in the same direction as the drum but with a slightly different speed, continuously pushes the sediment settled on the inner wall of the drum to the discharge port at the small end of the drum for discharge, while the clarified liquid phase flows out from the overflow port at the large end of the drum, thus achieving solid-liquid separation of the drilling fluid.

Product structure:

1. Drum: It is the core component of the centrifuge and is made of high-strength alloy steel with good wear resistance and corrosion resistance. The shape of the drum is conical-cylindrical. The conical part is used to further squeeze the dehydrated sediment, and the cylindrical part provides sufficient sedimentation space for solid-liquid separation.
2. Screw conveyor: It is installed inside the drum and arranged coaxially with the drum. The speed difference with the drum is achieved through the differential. The shape and size of the spiral blades are carefully designed to efficiently transport the sediment and prevent sediment blockage.
3. Differential: It is used to adjust the speed difference between the drum and the screw conveyor to ensure that the screw conveyor can discharge the sediment at a suitable speed. The performance of the differential directly affects the separation effect and processing capacity of the centrifuge.
4. Drive system: It is composed of motor, pulley, coupling, etc., which provides rotational power for the drum and screw conveyor to ensure the stable operation of the equipment.
5. Feed system: It includes feed pipe, feed pump, etc., which evenly transports the drilling fluid to the inside of the drum. The stability and uniformity of the feed have an important influence on the separation effect.
6. Slag discharge and overflow system: The slag discharge port is located at the small end of the drum, which is used to discharge the solid sediment after separation; the overflow port is located at the large end of the drum, which is used to discharge the clarified liquid phase.

Features:

1. Efficient separation: It adopts the principle of centrifugal sedimentation, which can achieve efficient separation of tiny solid particles in drilling fluid in a very short time, effectively improving the cleanliness of drilling fluid.
2. Continuous operation: It can realize continuous feeding, separation and slag discharge, and can realize uninterrupted solid-liquid separation process without stopping, ensuring the continuity and stability of drilling operations, and meeting the needs of large-scale drilling operations in oil fields.
3. Intelligent control: Equipped with advanced automatic control system, it can realize the functions of automatic start and stop, parameter adjustment and fault alarm of the equipment, realize precise control and optimize the processing effect, easy operation and reduce labor intensity.
4. Energy saving and environmental protection: The solid particles in the drilling fluid are effectively separated, which reduces the discharge of waste drilling fluid and reduces the pollution to the environment. At the same time, the solid phase materials such as barite recovered can be recycled to improve resource utilization.
5. Compact structure: The equipment is scientifically and reasonably designed, compact in structure, and occupies a small space, which is convenient for installation, commissioning and maintenance on the oil field site.
6. Strong processing capacity: It is suitable for drilling operations of various sizes, with large processing capacity, meeting the needs of efficient drilling.
7. Strong adaptability: By adjusting the parameters such as drum speed and differential speed, it can handle different types of drilling fluids, including complex situations such as high viscosity and high sand content.
8. Easy maintenance: The equipment has a simple structure, few wearing parts, low maintenance cost and long service life.
