撬装油气分离设备在胜利海六站的试验

撬装油气水分离设备不仅可用于海上平台油井(组)条件下油气水的分离,而且调整处理流程后还可以对污水进一步处理,处理后的水可作为回注水源。通过对高含水产出液的就地分离和回注,可以有效降低集输管线压力,降低边远区块船舶拉油成本。为了开发一井多用工艺技术,低成本和解决边远区块注水水源缺乏的问题,研制了撬装油气水三相分离设备,并在胜利油田完成了室内试验和现场试验,达到了预期的目标

Flow field of continuous phase in a vane-type pipe oil-water separator

In this work, the measurements of the swirling field of continuous phase in a new vane-type pipe separator have been carried out to validate the separation characteristics by the Particle Image Velocimetry. The radial, tangential and axial velocities were obtained. The results show that the new separator can successfully form a symmetrical swirling field. The transition region of the tangential velocity between the free vortex and the forced vortex shows a wider range than that in the traditional hydrocyclone. The axial velocity is always positive from the pipe wall to the central area and appears three-peak distribution. The tangential and axial velocities are dependent to the inlet flow rate, and yet show a low sensitivity to the ratio of flow split when the ratio of flow split is less than 13.1%. These results are helpful to the optimal design of the downhole oil/water separator.
