通过试验和机理研究，分析了原油预分水旋流器的除水分离能力。

This paper analyzes the mechanism of the hydrocyclone used for oil-water separation.

最后用实际外场采集的数据对该算法进行了测试分析，验证了其突出的信号分离能力。

Meanwhile, we utilize practical field data to test and analyse its performance of signal separation, and validate its perfect ability of signal separation.
