Causes and treatment of adhesive damage in polymer flooding injection pipeline

The viscosity of polymer liquid is an important parameter used in oilfield. Understanding the loss rule and regularity will help to improve distribution water injection quality ensure effective liquid. According oil-water data previous flooding fluid, it found that within range 5%-20%, with average 9.8%. reasons single well pipeline are complex varied, which closely related reducing substances, types quantities bacteria, fouling oil suspensions on inner wall pipeline, length running time. Therefore, from aspects Fe2+, time so on, influence factors prevention methods were studied, corresponding treatment measures worked out, good results obtained.
