During well drilling and completion,it is essential to ensure tight contact between the packer rubber sleeve and the casing inner wall to maintain normal sealing performance.Conventional procedures require cleaning the casings inner wall at the packer setting location to remove sludge,crystallization,and rust before running the completion string.In reservoirs with active oil and gas formations,increased wellbore operations elevate well control risks.Based on the work-ing principle of the hydraulic wall-cleaning and completion integration tool,an integrated wall-cleaning and completion process was adopted to safely and effectively reduce well control risks during completion operations.
