As a facility of drilling fluid tank-type solids control system , KOSUN Mud Agitator is mainly used to agitate and mix drilling fluid and keep stable performance and uniform mixing of circulating drilling fluid to avoid solid particles in drilling flu
KOSUN mud agitator plays an important role in drilling solids control system. Read More »
Drilling fluid materials (bentonite, barite powder, etc.) and corresponding chemical additives (polymer, etc.) are added into the circulating tank to prepare or increase the total volume of drilling fluid and to change the density, viscosity, water lo

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, with the contaminants being vaporized, as the cuttings move forward through the dryer to discharge. A high temperature separator filters vapors, removing dust and leaving recovered oil clean. Vapors are then condensed to a liquid phase and are processed through an oil/water separation system. Recovered water is used to re-hydrate the cleaned cuttings while the recovered oil is used in new mud or fuel in the burners. The system in the market specifically designed for treating oil based cuttings; C
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 and other solid substance. They are divided into clay, cuttings, weighting substance and solid substance in treating agent according to their sources in drilling fluid. According to the modes of action of them and their ions in water, low density solids further fall into active solids and inert solids. Active solids are easily hydrated and can react with other substances in liquid. This kind of solids has high surface activity and specific surface area with relatively active electroche
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, cuttings may even damage oil and gas reservoirs, reduce ROP, increase rotary table torque and cause blockage during tripping, even resulting in lost circulation, blowout and other complex downhole problems. Besides, cuttings in drilling fluid seriously abrade the circulating system. The key point for achieving drilling fluid recycling is to effectively treat the harmful solids contained within. Solids control system can effectively achieve such a goal. In the system, shale shaker can remove harmful so

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 ha
KOSUN KD series slurry separation system mainly consists of scalping shaker module, desanding module and desilting module. As a pre-screener, the scalping shaker can remove coarse particles from mud. The desanding module is equipped with desander (primary cyclones) and fine-mesh shaker and mainly removes granulated sand. The desilting module is equipped with desilter (secondary cyclones) and can conduct a fine separation selectively according to the field needs of customers. Mud closed-loop circulating purification mode and lower water content in slags help reduce the environmental pollution. Equipment parts of the system are of anti-corrosion and wear-resistance, long service life and low failure rate, and the system can be suitable for various severe working conditions. Simple and useful
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 on the excavation face, and maintain water pressure by the tension of mud film to balance soil pressure and water pressure on the excavation face. The soil and sand excavated are transported to the ground in the form of mud and are separated by slurry treatment equipment . The separated slurry is adjusted in specific gravity and then transported to the excavation face. After the engineering mud is treated by KOSUN waste treatment system, the dried solids can be up to the standard of landfilling 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 years. The most striking features of the pump are strong adaptability to media, stable flow rate, low pressure fluctuation and high self-priming capacity, which cannot be replaced by any other pumps. The single screw pump is a late-model pump based on the working principle of return mesh volume. Its main working elements are eccentric screw (rotor) and fixed lining (stator). These two elements form into separate sealed chambers due to their special geometries. The media are driven to uniformly flow along the axia
