Drilling fluid:Cool, lubricate, and support the bit and drilling assembly

We know drilling fluid possesses many functions. Here we will talk about another one of the functions of drilling fluid:Cool, lubricate, and support the bit and drilling assembly.

Heat is generated from mechanical and hydraulic forces at the bit and when the drill string rotates and rubs against casing and wellbore.

Cool and transfer heat away from source and lower to temperature than bottom hole.

If not, the bit, drill string and mud motors would fail more rapidly.

Lubrication based on the coefficient of friction. Oil- and synthetic-based mud generally lubricate better than water-based mud (but the latter can be improved by the addition of lubricants).

Amount of lubrication provided by drilling fluid depends on type & quantity of drill solids and weight materials + chemical composition of system.

Poor lubrication causes high torque and drag, heat checking of the drill string, but these problems are also caused by key seating, poor hole cleaning and incorrect bottom hole assemblies design.

Drilling fluids also support portion of drill-string or casing through buoyancy. Suspend in drilling fluid, buoyed by force equal to weight (or density) of mud, so reducing hook load at derrick.

Weight that derrick can support limited by mechanical capacity, increase depth so weight of drill-string and casing increase.

When running long, heavy string or casing, buoyancy possible to run casing strings whose weight exceed a rig’s hook load capacity.

In order to improve the use of drilling fluid, we need the treatment equipment i.e.  solids control system  solids control  solids control equipment  drilling fluid cleaning system   shale shaker    desander  desilter  decanter centrifuge  centrifuge centrifugal pump   mud cleaner   vacuum degasser   Hydrocyclone cone    mud agitator    flare igniter     submersible slurry pump  mud tank    mud gas separator   Jet Mud Mixer    mud mixing pump   mud gun  screw pump    Shale Shaker Screen    shearing pump   Vertical Cutting Dryer etc.

OGEM solids control is main professional manufacturer of solids control system in China, OGEM  is a vital part of the world hydrocarbon exploration and production industry, as well as one of top three solids control equipment suppliers in China, which offers its products for CNPC, CNOOC ,HH, Gazprom, RG, etc . If you want to know more information about solids control system and oil drilling solids control equipment  shale shaker,you can contact us online.
