What is a Drilling fluid shaker?

　　 Drilling fluid shaker What is it?

　　The Drilling fluid shaker is equipment used for solid control in the drilling mud purification system, featuring imported vibration motors. It is suitable for single-, double-, or triple-stage purification of oil drilling fluids and can also be used as the underflow shaker in mud cleaning units. The Drilling fluid shaker boasts high vibration intensity, a large screening area, adjustable screen box angle, compact structure, and excellent performance, making it widely applied in mud purification and treatment across various fields, including oil drilling, trenchless horizontal directional drilling, coalbed methane drilling, shale gas drilling, and environmental protection related to river sediment.

　　 Drilling fluid shaker It is a solid-control device in the drilling-fluid solid-control system. It can handle solid particles larger than 74 μm from the bottom of the well. The Drilling fluid shaker operates on the principle that, under the action of the eccentric mass of the vibration motor, the excitation beam transmits linear motion, circular motion, or elliptical translational motion. When the two motors are set at an angle to the screen surface or in a linear mode, their rotation directions are opposite, causing their excitation forces to cancel each other out in the X direction, resulting in zero net excitation force. Meanwhile, the reciprocating vibratory forces of the two motors in the Y direction drive the entire screen frame to move up and down along the Y axis, while simultaneously throwing the slurry across the screen mesh in the Y direction and allowing it to fall freely, thus propelling the slurry forward. As a result, the slurry passes through the screen and enters the mud tank, where the filtrate is separated out, and larger solid particles are screened out by the mesh, thereby purifying the slurry.

　　 Drilling fluid shaker It is mainly composed of a base, a screening box, a screening unit, a logging tank, vibration motors, vibration-isolation springs, control switches, and adjustment mechanisms. The screening box: It employs either flexible (or rigid) hook screens or frame screens, with bolt-tensioning or cleat-type fastening structures to ensure secure, reliable, and durable operation; the screen mesh is tightly secured to prevent damage, knots are sufficiently robust for dependable performance, and the unit is easy to operate and simple to maintain. The logging device: Drawing on well-known international brands, it features an optimized structural design that provides excellent mud-buffering performance and extends the service life of the screen tubes. The power unit: Composed of an impact beam and two explosion-proof vibration motors from reputable manufacturers, it delivers low-vibration noise, stable operating performance, long service life, and convenient installation and maintenance. The vibration-damping device: Utilizes a high-strength composite rubber structure that offers excellent stability, superior vibration attenuation, and low noise levels. The adjustment mechanism: Adopts a screw-adjustment design that provides high precision, good stability, and simple, convenient operation. The control system: Equipped with either explosion-proof or non-explosion-proof control devices from established brands, it boasts strong safety performance, effective soft-start protection, and a long service life.

　　Other vibratory screens have been tested but have not yet been commercialized. Most vibratory screens employ rectangular screen tubes: at the lower end of the vibration, coarse particles are removed, while fine particles pass through the screen tubes with the drilling fluid and are recirculated. Drilling-fluid solids larger than 74 microns exhibit relatively poor performance. The API 200-mesh vibrating screen was developed on this basis. Among weighting materials that meet the API grading standards, only 3% of the particle size exceeds 74 microns. At this size threshold, most barite is removed from the drilling fluid, which severely impacts drilling-fluid performance and increases drilling costs.
