水力射流复合解堵技术的研究与应用

Research and application of hydraulic jet and compound deplugging technology

针对安塞特低渗油田油层堵塞原因,研发了水力射流复合解堵技术,这种技术先使用酸液对地层进行解堵,再使用高压水力射流对地层进行二次处理,同时将物理、化学作用结合起来,提高了措施作用的深度和效果,在安塞油田取得了较好的应用效果,是一种处理油水井污染堵塞的高效增产增注技术。

According to the blockage reason of special low permeability of Ansai oilfield,this paper researches the hydraulic jet and compound deplugging technology,which uses the acid solution on the ground block firstly,then uses high pressure water jet on the ground for the second treatment,combined the physical and chemical effect together.It increased depth and effectiveness of the measures and achieved good results in Ansai oilfield,which is a effective technology to oil wells contaminated.
