With this equipment for the water preseparation and the wastewater treatment, 38% of the wastewater can be preseparated, and the outlet content of oil and suspended solids can be controlled under 15 mg/L and 5 mg/L, respectively, when the inlet water-cut is more than 80% and the concentration of suspended solids is less than 300 mg/L. With its high efficiency, the short process flow, the small size and the low investment, the equipment can be used for the water preseparation and the wastewater treatment at transfer stations of gathering systems and marginal oilfields, to bring about great economic benefits., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null,

articleAbstract=为克服高含水期油田预分水设施的局限性，对旋流、自溶气气浮、二级气浮、斜板聚结等技术进行集成研究，形成一体化预分水除油技术及装置。该装置取代了常规预分水除油工艺中的预分水器、除油罐、沉降罐等大型设备，具有预分水除油效率高、工艺流程短、占地面积小、投资低等优点，可用于集输系统的接转站和边缘油田就地预分水和污水处理。室内实验表明，在来液含水大于80%、含悬浮物300 mg/L 条件下，装置可预分出38%的污水，可将分出污水中的含油、含悬浮物指标分别控制在15mg/L、5 mg/L 以内，实现了预分水和除油功能的有机结合，经济效益明显。, correspAuthors=null, authorNote=胡长朝，博士，研究方向为油气田污水处理，电子信箱：hcc30503@163.com, correspAuthorsNote=null,
