Thermal Desorption applies heat to the Oil Based Mud Drilled Cuttings while isolating the flame from the cuttings. The oil vapor is isolated, so it can be recovered, condensed, and recycled, eliminating long-term liability. The cuttings are heated up indirectly in a large diameter, rotating dryer, w
Initially, it is necessary to look into composition characteristics of solids in drilling fluid and its influence on well drilling, so as to remove harmful solids economically and effectively for further recycling. Solids generated in drilling process mainly include mixing clay, weighting substance,
Cuttings are major harmful solids in drilling fluid and affect physical properties of drilling fluid during the whole drilling process, increasing density, viscosity, yield point, water loss, mud cake, abrasiveness, glutinousness and flow resistance of drilling fluid. During drilling process, cuttin

As environmental protection requirements on domestic oilfields are becoming more stringent, zero discharge drilling waste projects have skyrocketed in recent years. By virtue of years of experience in overseas drilling waste system equipment, KOSUN has provided complete set of zero discharge drillin
Slurry pressurized balanced shield: means that a partition is set in front of mechanical shield to form a slurry compartment between the partition and the cutterhead. The stability of excavation face is achieved in this way: feed mud into the slurry compartment, form a waterproof mud film with mud o
The single screw pump has been extensively applied in developed countries, which is often called as “ mono pump ” in foreign countries and known as “eccentric rotary pump” in Germany. For its excellent performance, the pump is rapidly used in a larger application range at home in recent year
Single screw pump is widely used in the oil drilling industry. Read More »
In urban subway construction, TBM has become one of the main choices for tunnel construction. The large amount of waste residue generated in the shield tunneling construction has brought many challenges to the urban environment. The dewatering, transportation, and landfill of residue will have a lar
