1、 Introduction to Shear Pump：

        Shear pumpIt is a machine specifically designed for shearing polymers and clays, which has been used on-site and theoretically proven effective. In the drilling fluid system, polymers (or clays) should be sufficiently sheared in advance before entering the drilling fluid system in order to fully exert their effectiveness and improve the performance of the drilling fluid. If not sheared sufficiently, the polymer may clog the vibrating screen in the first cycle, lose a large amount of polymer, increase drilling costs, and may also make large-sized solid particles in the drilling fluid hard and difficult to remove; In well completion fluid, due to insufficient shear, polymers will produce many "fish eyes". These "fish eyes" can damage the formation, reduce its permeability, and decrease the production of oil and gas reservoirs.
2、 Introduction to Shear Pump Function：
1. Shear pumps can greatly improve the hydration degree of soil moving particles.
The dispersion and hydration degree of soil particles in water depend on the electrolyte content, time, temperature, number and concentration of surface replaceable cations. Under the same conditions, using a shear pump can save more than 30% of bentonite.
2. Shear pumps can quickly shear, dilute, and hydrate polymers.
The high molecular weight of polymer used in mud is relatively high, and it is not easy to hydrate when directly added, so pre shearing is required for polymer. Shear pumps can provide high shear efficiency, accelerating the dilution and hydration process of polymers.
3.Shear pumps can provide high displacement and head, meeting the requirements for preparing and processing mud.
Shear pump is a new type of equipment designed to provide rapid preparation and processing of mud, which can meet the requirements of users for preparing high-performance mud. In the fiercely competitive drilling market, greatly reducing the mud preparation time will bring good economic benefits to enterprises.
