In drilling engineering, whether it is oil drilling or directional drilling, the mud or drilling fluid required for drilling needs to be mixed before being reinjected, so that mud circulation can be formed. Therefore, drilling fluid mixing is an important link after solid-liquid separation. The key to drilling fluid mixing is the drilling fluid mixing equipment or system.
Generally speaking, drilling fluid mixing has special drilling fluid mixing equipment. This drilling fluid mixing equipment is the drilling fluid mixing part in the mud circulation system, including: drilling fluid agitator, drilling fluid mixing tank, drilling mud mixing hopper, centrifugal pump, etc. This drilling fluid mixing equipment are finally integrated into a complete system called drilling fluid mixing system. The drilling fluid mixing system is all non-standard customization, and each drilling condition is different, and the drilling fluid mixing requirements are also different.
In the field of oilfield drilling solids control, the drilling fluid mixing system is generally composed of several drilling fluid mixing tanks and agitators. Because the drilling mud circulation system requires a large amount of reserve mud to meet the drilling needs, the oil field drilling fluid mixing system has a relatively large composition. The size of the horizontal directional drilling mud circulation system is much smaller than that of oilfield drilling, so the composition of the drilling fluid mixing equipment and system is relatively simple, with fewer drilling fluid mixing tanks and small volume.
Drilling fluid mixing requires the jet mixer to add chemicals, and the mixer is fully mixed in the mixing tank to achieve the specific gravity of the mud required for drilling. After mixing the mud, a centrifugal pump is required to transport the mud out. The drilling fluid mixing equipment home works together to achieve the ultimate purpose of mud circulation.
