根据油田生产需要，从试验分析出发，提出了水力旋流器的部分结构参数与操作参数之间的几个重要的关系式，进而研制开发了用于高含水油井产出液预分离的水力旋流器。并通过对其流场特性的分析发现，预分离水力旋流器的溢流口直径加大后，为提高预分离效率，必须将溢流管伸入旋流腔一定长度，同时操作参数也应控制合理。以此为依据试制出样机。油田现场试验证明，含水量在８５％左右的油井产出液经预分离水力旋流器处理后，其溢流含水量完全可达到小于３０％的指标，而底流水中含油也可降至１％左右，基本满足了处理后的水质指标要求，可在油田上推广应用。
According to the needs of oilfield production, several important relationships between some structural parameters and operating parameters of hydrocyclone are proposed based on the experimental analysis. Then, the hydrocyclone for pre-separation of production fluid in high water cut oil well Flow device. And through the analysis of its flow field characteristics found that pre-separation hydrocyclone overflow port diameter increases, in order to improve the pre-separation efficiency, the overflow pipe must be extended into the cyclone chamber a certain length, while operating parameters should Control is reasonable. Based on this prototype trial prototype. Oilfield field tests show that after the pre-separation hydrocyclone is treated with about 85% of oil production fluid, the overflow water content can reach an index of less than 30%, while the oil content in the bottom water can be reduced to 1% So that it basically meets the requirements of the treated water quality indicators and can be popularized and applied in oil fields.
