With the continuous progress of mud vibrating screen production technology and screen production technology, at this stage in the field of solid control of oilfield drilling, double-layer mud vibrating screens and even three-layer mud vibrating screens began to appear, this mud vibrating screen is not simple increase of a layer or multi-layer screen, but from the vibration screen motor electric control screen box structure and other places to innovate and redesign. The purpose is to build the traditional mud solid control vibrating screen into an integrated mud separation equipment, replacing the traditional 3-stage solid control equipment (mud vibrating screen desander, desilter). The result is to greatly reduce the procurement and configuration costs of the solid control system, and improve the efficiency of drilling mud treatment.
Double-deck mud shaker
First, look at the difference between 2 – and 3-layer screen mud shakers and traditional mud shakers. The overall volume of the double-layer mud vibrating screen and three-layer mud vibrating screen is much larger than the conventional mud vibrating screen, while the motor electronic control modular screen is much more advanced than the traditional mud vibrating screen, the entire equipment processing capacity is also powerful, which the mesh number of the screen through the layered structure to control the mud screening effect, a three-layer mud vibrating screen as an example, The mesh number of the upper, middle and lower layers of the screen is configured from large to small, and the treatment effect of each layer can achieve the treatment effect of the traditional solid control equipment.
Secondly, the improvement of the drilling process is also promoting the continuous upgrading of the mud vibrating screen, and the multi-layer mud vibrating screen has replaced the traditional solid control equipment, which has become a trend. The current drilling process requires solid control equipment and systems to be integrated and simplified, efficient, safe, and economical, and the emergence of multi-layer mud vibrating screens is in line with the current trend of drilling process improvement. It can be expected that multi-layer mud vibrating screens will become a trend to replace traditional solid control equipment.
