History of the Oil and Gas Drilling Fluids Solids Control System

Nov 22, 2013

Drilling fluids maintenance cost, clean up & disposal cost as well as the over all cost of boring, can be reduced dramatically when proper solids control techniques are utilized. These facts were recognized in the oil industry in the late 1800’s. When opening earthen pits, we used to separate the cuttings from the borehole. This was accomplished by a series of weirs and settling pits that allowed the solids to naturally settle out by using gravity. The clean mud then flowed into a suction pit to be re-pumped downhole. This was the first solids control technique ever used.

The next innovation in solids control came when the shale shakers were introduced in the early 1930’s in the oil industry. The shale shakers were derived from technology used in the mining industry. The shale shaker remains today the primary piece of solids control equipment utilized in the industry.

Another machine borrowed from the mining industry in the 1930’s was the cone classifier or hydrocyclone. The basic principle of this device involves the centrifugal forces brought about by the high velocity of the drilling fluids spinning in the cone forcing the larger and heavier solids to settle outward toward the cyclone wall and downward toward the underflow solids discharge. Together with the shale shaker, hydrocyclones have become the integral part of today’s solids control system.

In China's solids control industry, KOSUN is the professional and leader, we have been providing drilling mud equipment for over 20 years, they are extensively used in oil & gas drilling and workover, coalbed methane drilling, shale gas drilling, water well, etc.

The solids control equipment are consisted of shale shaker, shale shaker screen, desander, desilter, vacuum degasser, centrifugal pump, submersible slurry pump, shear pump, mud agitator, mud gun, drilling fluids mud cleaner, decanter centrifuge, jet mud mixer, mud tank, diesel tank, water tank and complete solids control system.
