Development and introduction of linear cavitation dispersant into the production process of well construction

Drilling in difficult mining and geological conditions involves the use of high-quality flushing and process fluids with the possibility of operational control of the component composition and properties. Currently, the use of emulsion drilling and technological solutions, the liquid basis of which is a direct or reverse emulsion of water and a hydrocarbon liquid, is relevant in the well construction processes. Insufficient efficiency of mass-produced preparation equipment leads to a decrease in the quality of the solution, which unreasonably increases the cost of materials, time and energy. The solution of this problem is related to the development of high–tech dispersant devices that combine cavitation and hydrodynamic effects. The principle of operation and technical characteristics of a cavitation dispersant are given, and approaches for such devices are formulated. By performing computational and experimental studies, a full-scale sample of a linear cavitation dispersant was developed and manufactured. The production process includes the preparation of a hydrocarbon-based solution for the process of wiring the trunk of the exploration well of the Chayandinsky oil and gas condensate field under the production column. During operation, the reduction in time for the preparation of hydrocarbon-based solutions compared to the standard dispersant was reduced by 55 %. Equipping solution preparation units with cavitation dispersants shall increase productivity and create more advanced technologies for producing drilling fluids, achieving design parameters within a few cycles.
