摘　　要：目前对油水分离器的研究主要集中在水力旋流器方面,没有涉及井下模块设计方法及性能测试等方面。为此,针对采上注下型井下油水分离系统,介绍了井下油水分离器模块化设计方法,指出井下油水分离器的设计首先要考虑井下管柱结构和井下工艺流程,在此基础上研究油水分离器模块的外部接口方案和内部引流方案,然后针对水力旋流器进行模块化设计。同时制造了模块样机1套,通过现场地面性能试验验证装置的分离性能。试验结果表明,处理流量固定时,随着分流比的增大,分离效率先变小后增大,在设计指标要求的范围内,油水分离器满足井场作业要求。Currently research on oil-water separator focuses mainly on hydrocyclone and it does not pay attention to the method of downhole modular design and performance testing. Therefore, revolving around the downhole oil- water separating system for upper production and lower injection, the paper introduces the method of modular design for the separator and points out that the downhole string structure and downhole technological procedure should first be considered. On the basis of this, the external interface scheme and internal drainage scheme of the separator module were studied. Then, the modular design of hydrocyclone was carried out. Meanwhile, a modular prototype was made. The separating performance of the device was verified by the field ground performance test. The field test findings show that when the treated flow rate is fixed, the separating efficiency first decreases and then increases with the increase of split ratio. The separator satisfies the well-site operating requirement within the scope of design index.
