渤海N油田降低回注水悬浮物粒径中值的实践探索

Practice and Exploration of Reducing Median Particle Size of Suspended Solids in Reinjection Water in Bohai N Oilfield

随着科学技术的进步,我国海上油田二次采油水力驱动的作用越来越明显,为保持较高的采收率,在日益严峻的环保形势下,海上油田对注水水质的要求更加严格。针对油田降低注水粒径中值的目标进行项目攻关,通过分析要因逐一解剖关键因素,制定实验目标确定降低粒径中值的方法,并且通过现场在线运行验证实验效果,排除非关键因素,提升效率。

With the progress of science and technology,the role of hydraulic drive for secondary oil recovery in offshore oil fields in China is becoming more and more obvious.In order to maintain a higher oil recovery rate,offshore oil fields have more strict requirements for water injection quality under the increasingly severe environmental protection situation.The project was aimed at the goal of reducing the median particle size of reinjection water in the oilfield.By analyzing the key factors one by one,the experimental objectives were formulated to determine the method of reducing the median particle size,and the experimental effect was verified through on-site online operation to eliminate non key factors and improve effi-ciency.
