Mud pumps are basic components of a drilling rig that pump drilling or mud in the drill pipe and up the annulus. Mud pumps are an important component in the direction of drilling, and their efficient and safe operation depends on the efficient use and maintenance of these pumps. This article seeks to explain how to use mud pumps for drilling rigs and how to maintain them.
The Use of Mud Pumps for Drilling Rigs
The fact that the mud tanks require to be checked and fined regularly makes the transportation method suitable for this process. This is because the mud tanks must be checked prior to the start of each shift to verify that there is sufficient drilling mud for use. Barite is added in varying proportions to alter the weight or density of the mud as the need arises. Some of the important mud properties that need to be maintained are weight, viscosity and gel strength, which can greatly affect hole cleaning, well control and drilling.
When using primed lines, every pump should be started slowly, and one should check for leakages, unusual noises or vibrations as a sign of a problem. After starting up the pump, ...
... the pump strokes/speed should be regulated to get the optimum flow rate down the well bore. Currents in pumps must also be monitored, often concerning the output pressure, temperature and volume of the fluid, as well as other standards.
Priming the Mud Pumps
Before the mud pumps are turned on, the suction and discharge lines have to be charged or primed with drilling mud to prevent any issues. First, open the fill line valve and let the mud flow through the mud tanks to the suction manifold without any air. Turn off the fill line valve when the fill line is full and eliminate any of the remaining air pockets by operating the pump on and off to effect the full priming of the line.
Routine Maintenance
A list of some maintenance checks that could be done every day includes checking the pump fluid ends, liners, washers, values and plunger rods for signs of wear and leakage. Some of the maintenance routines that should be scheduled for drilling equipment tools include the replacement of plunger rods, valves and liners in relation to the number of run hours. Replace mud pump fluid ends using new parts as supplied by the OEMs, typically 5,000 operating hours. This means that one should only replace those faulty parts and products with other ones that have been recommended by the manufacturers to enhance their performance and not fail as they did.
The Bottom Line
Mud pumps are perhaps the most crucial component in any pumping system used in a drilling rig. Maintenance thus guarantees optimal use of equipment for drilling operations and thereby helps in avoiding situations that will lead to costly downtime. Drilling equipment tools are often equipped with more than one pump, and thus, pump failures can be accommodated without significantly interrupting drilling activities while the failed pump is being repaired.
