Description

Technical Field

[0001] The utility model relates to the technical field of barite powder modification and activation, in particular to a barite powder modification and activation device for drilling fluid. Background Art

[0002] Modification and activation of barite powder for drilling fluid refers to the specific treatment of barite powder to improve its properties and make it more suitable for drilling fluid applications. Specifically, the modification and activation process usually involves physical, chemical or mechanical methods to change the surface properties, particle size distribution, dispersibility, etc. of barite powder, thereby improving its stability and functionality in drilling fluid. Through modification and activation, barite powder can better interact with other components in the drilling fluid, enhancing the suspension, rheology and other key properties of the drilling fluid. This helps to improve the results of drilling operations, increase drilling efficiency, reduce costs, and potentially reduce environmental impact.
