Recycle the drilling mud that lubricate the drilling bits.

The drilling mud solids control system is for filter away danger solids phase that contain in the drilling mud and reuse the needed solid phase.  The task is to keep drilling fluids in stable performance status.  There are several machinery that will need to perform the tasks.

The result of consist performance of drilling mud is avoid the blocking and damage of the oil and gas channel. It reduce the well drilling torque and friction drag and reduce the pressure oscillation of the annular air suction.  It also increase the velocity of the well drilling, extend life of the drill bit, reduce wear of the equipment.

drilling mud system

There are  five steps of filtering process that require five solids control machinery that will do  filter screening, degassing the mud, desanding the mud, desilting the mud, centrifuge force separation and demand of weighting up mud. The consist work flow between every solids control equipment use in the whole system is very important.   Level one to five level of output of the mud should be matched each other and the interval of separation size should be appropriate and have a certain overlap.  The result of the smaller solids which are not filter by the upper can be filter in the next controlled level.

With the development of well drilling technology, mud mixing system plays an important role in drilling operation. The various kinds of solids control systems function at the same time. Regardless the different kind of the solids control system, it’s basic function will not changed. It is depend on organic combination of mechanical removal equipments, drilling fluid mud tanks and other auxiliary equipments to accomplish the basic function:  Recycle the drilling mud that lubricate the drilling bits

Yesterday, GN’s manufacturing department done the fabrication of a mud mixing tank with increase hoppers. Mud mixing tank is widely used in the drilling mud system regarding mixing and re-configuration the actual drilling fluids. Also this will be used for storage the particular active drilling fluids.

mud mixing system
The mud mixing system is actually consisting of mixing tank, mud agitators, mud guns, mixing pump and mud hoppers. Usually, the mixing pump as well as the mud hopper will be situated at one end with the mud tank to make the mixing tank system a compact and also single unit, while in a few projects, the mixing pump and hopper are installed on another skid so that the mixing tank and the jet mud mixer could be used much unhampered. The picture in this article shows that the particular jet mud mixer skid was located at 1 side of the mixing mud tank. There are one mixing pump and 2 mud hoppers on the skid. The mixing pump is connected with the two hoppers, one of the hoppers is needed for mixing barite to create weighted drilling fluids, plus the other one is used for including bentonite into the drilling liquids.
There is a steel frame about second hopper with iron bars over the hopper. This specific horizontal steel bar is needed to hang the bentonite handbag which will be hooked at several corners of the steel structure to make it easier for adding typically the bentonite powder into the hopper. It is worthy to mention the fact that steel bar is with forklift lifting slot so that the club with bentonite bags may be lift and put on the shape by a forklift to save man power.
This mud mixing system is with a control panel to control mixing pump which could transfer mud to both hoppers. Around the mixing tank, there is one more charge pump which is used to help transfer the active mud back to the rig with regard to reuse.

Decanter centrifuge operate in RPM speed and proper operation temperature is essential for smooth operation.  Unusual operation temperature raising and the temperature can’t be reduce is major issue in machinery operating.


Centrifuge operation temperature during normal operating should be around 40 degree C.  It is common when flush and change new oil and lubricants and turn the centrifuge on, the temperature will be raising them the normal operation temperature but eventually will comes down.  If the temperature do not come down, there are few points need to check with.


First need to check the level of oil and lubricants in the gearbox and bearing while centrifuge is not operating.  Too little oil and lubricants will not proper lubricant the moving parts and gears in RPM operation causing grinding in the long time  and lead to permanent damage.  In opposite situation too much oil and lubricants will cause oil and lubricant not flow properly between gear and parts.  The air and oil mixing ratio is not balanced will cause temperature raise and not coming down as well.


Properly flush the oil in gearbox by turning it upside down and wait until all the oil draining down.  Once draining is complete, turn the filler hole to 10 o clock position and fill the gearbox oil.  Once shows the sign of overflow the oil while filling, it shows enough oil is filled and stop.  Close the draining plug and do not topping the gear box oil.


After filling up the gear box oil, turn the machine on and take initial temperature check.  Every 15 minutes, it needs check the gearbox and bearing temperature and get the uprising temperature curve.  After turn the drilling mud decanter centrifuge on for 2 hours, it should reach to maximum temperature and starts to reduce the temperature to 40 degree C.  If temperature do not come down after 2 hours, stop the machine and open up the drain plug.  Take the compressor connect with hose and trigger and blow the air into the drain plug.  During the filling of the new gearbox oil, it might mixed with air to create air bubble in the gear box.  Eliminate the air bubbles and turn the decanter centrifuge back on will result the temperature comes down to normal operation temperature.
