AI Technical Summary
Technical Problem
During operation, the hydraulic hydrocyclone pipes in offshore oilfields suffer from reduced pipe diameter and rough wall surface due to the accumulation of oil sludge and iron oxides, resulting in poor oil-water separation. Existing static immersion cleaning methods are ineffective.
Method used
The cleaning process employs a dynamic circulation of water-soluble acid cleaning solution and organic solvent cleaning solution to dissolve iron oxides and sludge, respectively. The cleaning solution is then separated by a filter and reused to form a two-layer structure for cleaning.
Benefits of technology
It effectively removes iron oxides and sludge from inside the pipe, significantly improves oil-water separation efficiency, and greatly enhances cleaning effect.

Abstract
本申请公开了一种海上油田水力旋流管清洗装置及清洗方法。所述清洗装置包括清洗槽，所述清洗槽内沿水平方向分为清洗区、滤渣收集区、静置澄清区；所述清洗区的底部形成配水区，清洗区内设有多个供水力旋流管插入的孔口；所述滤渣收集区和静置澄清区之间设有滤网；所述静置澄清区连接在竖直方向上间隔一定距离的第一出水管和第二出水管，第一出水管和第二出水管的空余端汇合后与水泵的入口连接，水泵的出口通过进水管与配水区连通。本发明方法采用水溶性酸洗液和有机溶剂洗液分别对铁氧化物和油泥进行溶解，并动态循环清洗，管壁内的铁氧化物和油泥可以得到有效的清洗去除，旋流管油水分离效率得到极大提升。
