CEMENTING JOB OVERVIEW 1. Preparing casing 1st a drilling mud is circulated down thru csng to condition & clean the well, usually done by rig. A pressure test is done by pumping unit, checking that there are no leaks in lines that connect pumping unit to well. Then 2 fluids: chemical wash & a spacer are pumped in.Chemical wash helps thin & disperse mud in wellbore & annulus (space b/w csng & formation). Spacer's job is to keep mud & slurry separated. • • • The wash & spacer may also be designed

Triplex Mud Pump Work Principle During operation, the power machine drives the main shaft and the crank that is fixed thereon by a transmission component such as a belt, a transmission shaft, and a gear. When the crank rotates counterclockwise from the horizontal position from left to right, the piston moves to the power end, the pressure in the liquid cylinder gradually decreases and a vacuum is formed, and the liquid in the suction pool is under the action of the liquid surface pressure, and t
