Drilling Waste Management Solutions

With the increasing attention to environmental protection, drilling waste randomly disposal has been seriously forbid by many countries. Considering the global need of such kind of equipment need, KOSUN focused on drilling waste management solutions for many years.
Contamination of drilling fluids with drilled cuttings is an unavoidable consequence of successful drilling operations. If the drilling fluid does not carry cuttings and caving to the surface, the rig is not either “making hole” or soon will be stuck in the hole it is making. The drill cuttings that are separated from the drilling fluid on the surface by the solids control equipment and some quantity of unrecoverable or economically unwanted drilling fluid are a major source of drilling waste. Drilled and formation solids that are sized smaller than can be removed by the solids control equipment are often reported as drill solids. Some quantity of drill solids will accumulate in the drilling fluid and must be removed by the solids control equipment or reduced in concentration by dilution.
Before the introduction of mechanical solids-removal equipment, dilution was used to control solids content in the drilling fluid. The typical dilution procedure calls for dumping a portion of the active drilling-fluid volume to a waste pit and then diluting the solids concentration in the remaining fluid by adding the appropriate base fluid, such as water or synthetic oil.
Using solids-control equipment to minimize dilution has been a standard practice for the drilling industry for more than 60 years. Drilling waste management equipment and methods have changed over that time, but the fundamentals behind the process have not.

During the drilling waste management, KOSUN combines decanter centrifuge, hi-G dryer shale shaker, vertical centrifuge/cuttings dyers and screw conveyor as a system to ensure environmental harmful cuttings not back to nature. And the system has shown superior running efficiency in Russian market with high evaluation from our customer.

Mono Screw Pump Working Principle and Apllication

M ono screw pump , also called  sewage pump  or  progressive cavity pump ,  belongs to the rotor type positive displacement pump .   M ono screw pump  is depend ing  on the screw meshing with liner on the discharge and suction cavity to conveying liquid volume change.   It is a kind of method of pressurized screw pump, a main working parts by bushing has a double helix cavity (stator) and the stator cavity and its meshing singlehead screw screw (rotor).   When the input shaft through the universal joint drive making planets revolving around the center of the stator, rotor stator, rotor, vice is continuous mesh form sealed cavity, the seal chamber volume invariably uniform axial movement, the medium from the suction end of deputy to the stator, rotor pressure side, the suction medium sealed cavity through the stator without stirring and destruction. M ono screw pump  is an ideal pump used to feed drilling fluids to ...

Shale Shaker Screens Types and Application

S hale shakers typically consist of wire mesh  shaker screens  in various mesh sizes that shake or vibrate the drill cuttings which across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s  and back into the drilling mud system.  There are mainly three types of shaker screens for different types of shale shakers, like PWP screen, PMD screen, and hook strip screen. PMD screens are Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers . While PWP and hook strip screens are widely used for world famous shale shakers like brand M-I SWACO, Derrick, Brandt and KOSUN. Hook strip s creen s  is a  common kind of s hale s haker s   s creen, which can be widely used in different conditions in drilling operation. This screen is constructed with two  or three layers of stainless steel wire cloths bonded to a steel...
