Rotary Drilling Slurry Treatment System
Abstract:
Rotary Drilling Slurry Treatment System ( Desanding Plant ) can help rotary drilling rig mud to achieve cooling and lubricating drill bit. The article will intruduce four functions of rotary drilling slurry treatment system.
Rotary Drilling is one construction technology suitable for pore forming operation in building foundation engineering. It is widely used in foundation construction projects such as municipal construction, highway bridge, high rise building and so on, matched with different drilling tools, adapted to dry (short spiral), or wet (rotary bucket) and rock formation (core drill) pore forming operation. Rotary drilling slurry treatment system is the necessary equipment for rotary drilling.
Rotary drilling slurry treatment system helps rotary drilling rig slurry realize the following functions:
1.Flushing bottom hole: Rotary drilling slurry creates a high velocity flow at the drill bit water jet towards the bottom of the well. The special chemical mud produced by the high speed jet drilling rig can be washed away from the bottom of the well with the chemical mud pressure and the formation pressure difference of the rotary drilling rig, and it plays the role of washing the hole bottom.
2.Rotary drilling slurry treatment system can help the rotary drilling rig to carry out the function of debris: When the special chemical mud of rotary drilling rig is larger than the speed of cuttings sedimentation, the special chemical mud of rotary drilling rig can bring the cuttings out, that is, at a certain speed of return, the special chemical mud of rotary drilling rig has the function of carrying cuttings.
3.Rotary drilling slurry treatment system helps to achieve balanced formation pressure in rotary drilling rig mud: The liquid column pressure of special chemical mud for rotary drilling rig must be balanced with the formation pressure, so as to prevent the blowout or the special chemical mud of the rotary drilling rig. The fluid column pressure of mud can be controlled by adjusting the density of mud to balance the formation pressure and play a role in preventing leakage and plugging.
4.Rotary drilling slurry treatment system can help rotary drilling rig mud to achieve cooling and lubricating drill bit: The special chemical mud of the rotary drilling rig can bring the heat of the drilling tools (drill and drill string) and the formation friction to the ground in the course of drilling, and play a cooling role. At the same time, the chemical mud of rotary drilling rig can effectively reduce the friction between the drill and the formation, and play a role in lubrication.
