Oilfield drilling fluid Shale Shaker screen life is too short, how to extend the screen life?

Reasons for the short life of oilfield drilling fluid Shale Shaker mesh:

1. The screen quality is unqualified

2. The screen is not fully tensioned

3. The screen protective rubber strip is missing or damaged

4. Vibration motor steering error

5. Material accumulation and material flow rate

How to extend the service life of screen mesh

1. Purchase a screen mesh from a regular manufacturer with a good reputation

2. The screen is not fully tensioned. As long as the screen is installed flat, do not cause mechanical damage to the screen during use. The vibrating screen can prolong the service life and reduce the rapid damage of the Shale Shaker.

3. Refill or replace the protective rubber

4. The vibration motor turns wrong. When debugging the steering of the vibrating motor, the on-site operators believed that as long as the drill cuttings moved forward based on the experience of using the mud linear vibrating screen in the past, this method not suitable for balanced elliptical vibrating screen. If the motor rotates inward by mistake, the projection angle is also forward, but the drill cuttings have the force to roll backwards. At this time, the forward movement speed of the drill cuttings is much slower, and it stays on the screen for a long time, which may even lead to drilling. Chips cannot be expelled. Then, it is necessary to ensure that the manufacturer conducts systematic training for each operator on the operation of the equipment before use.

5. When the drill cuttings accumulate on the Shale shaker screen and damage the screen quickly, we should increase the vibration amplitude: flush the screen and cuttings with sprayed water to reduce the viscosity of the cuttings, but this method is only suitable for allowing the addition of water Adjust the angle of the screen at the D end of the sand discharge to downward, which is conducive to the discharge of cuttings by gravity, but it should be noted that improper operation may lead to slurry running; replace the mesh of the screen or adjust the flow rate of the single screen to ensure the flow of drilling fluid. The dead point is close to the screen outlet, so that the cuttings can be discharged smoothly under the lubrication of drilling fluid.
