SAGD高温高效仰角式预脱水装置

SAGD High-temperature and High-Efficiency Elevation Dehydration Separator

为确保SAGD采出液密闭分离水质达标,研制开发了SAGD采出液预处理装置。该装置采用卧式仰角结构,筒体与地面呈12°安装,通过内部高效聚结元件设置,容器空间得到有效利用,实现油气分离、油水分离、液固分离,整个分离器内部无死液区。设计上采用整体应力分析计算,优化了支架、容器结构,具有分离效果好、分离精度高、安全可靠、使用维护方便、生产运行成本低等优势,针对高含水油田有一定的推广应用价值。

The SAGD produced liquid pretreatment device is developed to keep the quality of liquid in line with the standard after closed separation. The device adopts a horizontal elevation structure and its installation has a 12-degree angle with the ground. The container space can be used effectively thanks to the internal high-efficiency node element arrangement, thus bringing about oil-gas separation, oil-water separation and liquid-solid separation. The inner of the separator is free from dead-zone liquid. The design adopts overall stress analysis and calculation to optimize the support and structure of the container. Therefore, it has good separation results, high separation accuracy, reliable safety convenience for use and maintenance, and low cost for production and operation. The separator can be widely used in the high water-cut oilfields.
