Functional characteristics of high speed shear pump
Sep 07, 2022
High shear homogenizing pump is a kind of machinery specially used to shear polymer and clay, which has been used in the field and proved effective theoretically. In the drilling fluid system, the polymer (or clay) should be fully sheared in advance before entering the drilling fluid system to give full play to its utility and improve the performance of the drilling fluid. If it is not fully sheared, the polymer may block the vibrating screen in * cycles, lose a large amount of polymer, increase the drilling cost, and make the large-sized solid particles in the drilling fluid hard to remove; In the completion fluid, the polymer will produce many "fish eyes" due to insufficient shear. These "fish eyes" will damage the formation, reduce the formation permeability and reduce the production of oil and gas reservoirs.
The high shear homogenization pump can provide high shear for the rapid hydration of polymer (or clay), and solve the prominent problem of poor hydration of polymer (or clay) in drilling fluid or completion fluid. At the same time, the use of the shear pump can reduce the amount of polymer by more than 15% and the amount of bentonite by more than 30%, improve the loss of mud cake and fluid flow, reduce the shear ratio rate of drilling fluid, and improve the gel strength, reaching the advanced level of similar products abroad. Its shaft seal structure is more reliable, has excellent performance, and is more convenient for use and maintenance.
