The two main performance parameters of mud

The two main parameters for the performance of mud displacement and pressure. To discharge certain displacement in liters per minute, it’s mud hole diameter and fluid from the required return on the speed of the bottom of the hole, that the larger the aperture, the greater the required displacement. Required rate of return on the fluid able to cut down the drill cuttings rock powder promptly washed from bottom of the hole, and reliably carried to the surface.

When the geological core drilling, generally return rate of about 0.4-1 m / min. Mud pump pressure depends on the depth of the borehole, the fluid resistance of the channel through which the nature of the transported fluid and the like. The deeper drilling, the greater the pipeline resistance, slurry pump manufacturer the higher the pressure needed. With the change in the depth of the hole diameter equired pump displacement can be adjusted at any time. The transmission mechanism is provided in the mud or to adjust the speed of the hydraulic motor in order to change the displacement of the object.

In order to accurately grasp the changes in pressure and displacement mud to mud flow meters and pressure gauges installed, ready to make people understand the functioning of the drilling mud, while the hole by pressure changes determine whether the normal situation in order to prevent the occurrence of holes accident.
