Technical Practice of Working Fluid Affecting Cementing Safety and Pollution Prevention in T Oilfield
Cementing engineering is the most critical link in drill-ing engineering,with high investment and safety risks.Even a slight mistake can lead to situations such as high pump pressure,long paste plugging,and super delayed setting,and even malignant engineering accidents such as"sausage filling"and"flagpole inser-tion".The slurry technology among them is an important factor af-fecting construction safety,including the mixing of dry ash materi-als,dry ash,compatibility of slurry water,compatibility of cement slurry,drilling fluid,isolation fluid,and other issues.This article conducts relevant work from various aspects such as treatment agents,external admixtures,and working fluid systems through in-door experiments and on-site practice,to identify potential techni-cal hazards that affect construction safety.This ensures the safety of cementing site construction and fundamentally avoids the occur-rence of complex cementing situations and safety accidents.
