In the process of drilling to the hole
transporting mud or water drilling fluid machinery. A piston type, centrifugal
type, screw type, diaphragm type. slurry pump volume and pressure, according to
the hole diameter and depth as well as types for drill and drill and rational
choice. In order to guarantee the smooth bottom hole drill can take down the
debris timely delivery to the surface, such as geological core drilling on the
return flow in 0.3 ~ 1 meters / seconds. slurry pump pressure to reduce the
pressure loss along the fluid flow resistance caused by the general anti cycle,
pressure drop is greater than the positive cycle; the tool and the hole wall
gap smaller pressure drop is bigger; hydraulic jetting drilling consumption
pressure larger; mud density is the need to pump pressure greater. The total is
Shenyu big hole, the pump pressure should be greater. In addition, when the
bottom hole of turbine drill and screw drilling, slurry pump supply working
power of the drilling mud become, the required pressure more than conventional
drilling. China has produced a series of products of slurry pump is suitable
for the geological core drilling, water well drilling and oil and gas drilling.
