Last week, a batch of diesel-driven shear mixing units customized by Xi’an KOSUN for CNOOC International Division was packaged and shipped to be used in an offshore drilling platform project.

Shear mixing units are equipment used in conjunction with the solids control system for oil drilling.  When formulating or increasing the total volume of drilling fluid, adjusting the density, viscosity, and filtration loss of the drilling fluid, drilling fluid materials (such as bentonite, barite, etc.) and corresponding chemical additives (such as polymers) need to be added to the circulating tank.  When formulating drilling fluid, various drilling fluid materials and chemical additives need to be mixed evenly to achieve optimal drilling fluid performance.  Directly adding chemical additives into the tank can cause a large amount of sedimentation or agglomeration of drilling fluid materials and chemical additives, resulting in poor dispersion.   Therefore, a shear mixing unit is needed to handle this process, ensuring that various drilling fluid materials and chemical additives are mixed evenly under strong jet impact and continuous circulation.

The shear mixing unit produced by Xi’an KOSUN consists of a shear pump and a jet mud mixer, which are orderly connected and installed on a base.  The shear pump is directly driven by a diesel engine, with high transmission efficiency and compact structure.  The product has reliable performance, is safe to use, and is easy to transport.   It can meet the requirements of weighting and formulation of drilling fluids for drilling solids control systems ranging from 1500 meters to 6000 meters.

Xi’an KOSUN belongs to the high-end environmental protection equipment manufacturing industry.  Its products are mainly used in the treatment, disposal, and resource recycling of solid waste.  The shear mixing units produced by our company have been applied in oil drilling sites, subway tunnel construction sites, non-excavation construction sites, and have received unanimous praise from customers.
