What is the reason for the oilfield drilling fluid shale shaker to run out of slurry?
Today, I will popularize the reasons for the shale shaker to run the slurry! Drilling fluid shale shaker is the most used solids control equipment in the process of oil drilling mud treatment. BZ Solids Control drilling fluid shaker has the advantages of high vibration intensity, large screening area, adjustable screen box angle, compact structure, etc. Therefore, the drilling fluid shaker plays a decisive role in the entire mud purification system. At present, drilling fluid shale shaker are widely used in oil drilling, trenchless horizontal directional crossing, coalbed methane drilling, shale gas drilling, river silt environmental protection and other fields of mud purification.
In general, there are three reasons why the drilling fluid shaker runs out of slurry:
Factors of drilling fluid or mud:
1. The viscosity of the mud is too high.
2. The proportion of mud is too large.
3. The solid phase content is too large.
4. Drill cuttings are dispersed.
Factors of shale shaker performance:
1. The excitation force is small.
2. The mesh number of the screen is too high.
3. The effective area of the screen is small.
4. The choice of vibration trajectory determines the mud moving speed.
5. If the screen is used, the mud is unevenly distributed on the screen surface and is biased to both sides.
Maintenance factors of drilling fluid shale shaker:
1. The screen box elevation adjustment is too small.
2. The rotation direction of the vibration motor is wrong.
3. Too much pulp supply exceeds the maximum capacity of the shale shaker.
4. The screen mesh is blocked, and it should be flushed with clean water regularly during use.
5. When the machine is shut down, the screen is not rinsed with clean water in time, causing the mud to dry and solidify.
6. When the mud performance changes, the percentage of the eccentric block of the vibration motor is not adjusted accordingly in time.
The above factors are the main reasons why the drilling fluid shale shaker runs out of slurry during the use process. BZ Solids Control drilling mud shale shaker has the characteristics of high vibration intensity, large screening area, adjustable screen box angle and compact structure.
