The oil drilling mud tank is typically made of square steel tube and steel plate, to store drilling fluids on a drilling rig. In drilling fluids solids control system, all the drilling solids control equipment are mounted on the top of the mud tank.
Oil-based drilling fluids is mainly composed of oil as the continuous phase. It has found wide application in various drilling platforms with its resistance against elevated temperature and calcium salt corrosion, strong sidewall stabilization, good lubricating effects and little damage of oil & gas formation. Water, as an unuseful composition, does not account for more than 10% in oil-based drilling fluids. However, it normally takes up 10%~60% in water-in-oil drilling fluids, as an essential part evenly dispersed in diesel.

Recently, KOSUN Black Rhino Shale Shaker and Black Rhino Centrifuge were officially put into production.The KOSUN Black Rhino Series solids control equipment being manufactured mainly contains shale shaker and drilling centrifuge.
Black Rhino Shale Shakers
Desanders and desilters are solids control equipment with a set of hydrocyclones that separate sand and silt from the drilling fluids in drilling rigs,which is sorted by shale shaker in the first phase of solids control system.

The Desander works on the principle of centrifugation.forced by centrifuge, drilling mud run into hydrocyclones with certain velocity and pressure, and the gravity forces the larger particles down to the bottom and discharge from the outlet onto the shale shaker screens,while the lighter ones, due to the centrifugation, spiral up around the central core and flow into centrifuge(the 4th phase solids control equipment) to be further treated.
Drilling fluids, the circulating fluid for drilling operations, is a mixture of the fluid, the solid and chemical agents. It is usually known as the “mud” or the “blood of drilling” deriving from its distinctive significance.
The solid in mud primarily includes concocting clay, weighting materials, drill cuttings and other solid substances. In terms of sources, it then comprises concocting clay, debris, weighting materials, solids from agents, etc.
Besides, different types of action of solids and ions in water can further categorize low-density solids into active and inert ones.
How to dispose of drilling cuttings is one of the problems facing the oil and gas industry. Oil and gas drilling operation generated large volume of drill cuttings and spent mud. Drill cuttings are produced as the rock is broken by the drill bit advancing through the rock or soil. Muds are circulated through the drill bit to lubricate and cool the bit.drill cuttings are usually carried to the surface by drilling mud and separated out by mechanical means, such as, shale shaker, mud cleaner.etcVertical Cutting Dryer

Decanter centrifuge is the 4th phase cleaning equipment in a complete solids control system to separate fine solids. It is the most high technology products among all solids control equipments.
Decanter Centrifuge Working Principle
Drilling waste management was established in the drilling industry post 1980’s, which is driven by high exploration and production activities, ever increasing stringent government regulations and escalating investments from the oil and gas operators. The trend is set to continue further with the current surge in offshore activities and shale reserve exploratory activities. The global drilling waste management market is therefore expected to grow to approximately $8 billion by 2018, at a CAGR of more than 10% from 2013 to 2018.
