How to deal with the slurry running during the use of drilling fluid Shale Shaker

How to deal with the slurry running during the use of the drilling fluid Shale Shaker? In the previous article, we have analyzed the reasons for the running slurry of the drilling fluid Shale Shaker. In this article, we will talk about how to solve the problem of slurry running? How many steps to start?

The method of running mud treatment during the use of the drilling fluid Shale Shaker

The number of meshes selected is unreasonable. The capacity of each vibrating screen is 50L/s. This is because the conditions of the capacity test are based on the standard: a 60-mesh screen is selected, and the specific gravity is 1.8 to test the weight of the mud. The viscosity of the mud is that the mud contains rivers of different particle sizes. sand. Due to the rapid drilling of the surface layer, a large amount of solid phase is generated, which takes up the effective screen area, so the vibrating screen cannot use fine screens in shallow wells. Therefore, a larger hole screen should be used at the beginning of drilling, and as the drilling depth increases, finer screens should be gradually adopted.

The formation and mud conditions affect the throughput. Since the drugs added in the drilling fluid are not fully dissolved and paste on the screen, serious slurry running will occur at this time. You should wait until the drug is fully dissolved before using it, or use a larger mesh screen. On the other hand, when drilling into a loose sand-bearing layer or quicksand layer, the sand particles are likely to get stuck in the screen holes, causing screen blockage. Therefore, it is necessary to test several screens with different meshes to reduce the blocking phenomenon.

Check whether the rotation of the motor is correct. First, remove the vibrator shield and check whether the eccentric blocks of the two motors rotate outward. Secondly, if the steering is wrong, please exchange any two phase wires in the incoming power supply of the electric control box. The first error method (two motors rotate towards the inside), although the drill cuttings can also be removed outwards, but the speed is slow; the second error method (two motors rotate in the same direction), the vibration is very small, and basically does not discharge sand or process mud.

Check the amplitude of the Shale Shaker. The larger the vibration amplitude is, the more general processing capacity is; the vibration force is adjusted to 90% when leaving the factory. If there is a situation of running pulp, you can align the angle of the inner and outer eccentric blocks, and the vibration force is.... (At this time, the mud processing volume only increases by about 15%)

Check whether the liquid flow distribution on the screen frame is reasonable. For the vibrating screen with a hook-side screen structure, the screen surface on both sides is lower than the middle, and the mud is easy to flow to both sides and lose. It should be ensured that the mud enters the screen frame from the middle. At this time, two solutions can be adopted. One is to adjust the front spring seat to properly raise the angle of the front of the screen box; the other is to adjust the position of the turning plate of the extension slot to control the distribution of liquid flow.

How to deal with the slurry running during the use of the drilling fluid vibrating screen? The above 5 points are to deal with the slurry running problem of the Shale Shaker. I hope that customers can deal with the problems they encounter after reading them.
