Shear Pump: Advanced Polymer and Clay Shearing for Efficient Drilling Fluid Performance

JQB 5x6J-11 shear pump is specially used to shear polymer and clay in drilling fluid. The polymer (or clay) in drilling fluid system should be shear sufficiently in advance, then enter the drilling fluid system to improve the performance of drilling fluid, so as to give full play to its utility. If not shear sufficiently, the polymer may block the vibrating screen in the first circulation, lose a large amount of polymer, increase the drilling cost, and may also make the large-sized solid particles in drilling fluid hard and difficult to remove; In the drilling fluid, due to insufficient shear, the polymer produces many "fisheye", which damages the formation, reduces the formation permeability, and the production of oil and gas reservoirs. It has been proved that the JQB 5x6J-11 shear pump has excellent performance. It can provide high shear for  the  rapid  hydration  of  high  molecular  polymer  (or  clay),  and  solve  the  outstanding problem of polymer (or clay) in drilling fluid due to poor hydration. The JQB 5x6J-11 shear pump can reduce the amount of polymer by more than 15%, the amount of bentonite by more than 30%, and can reduce the loss of mud cake and liquid flow, reduce the shear ratio rate of drilling fluid, and improve the gel strength. Therefore, it has reached the advanced level of similar products  abroad.  Through  design  improvement,  the  pump  uses  cemented carbide mechanical seal and tetrafluoroethylene packing double-layer seal, its service life is greatly improved, and the use and maintenance are more convenient.
