摘要:
分离器设备是海上平台上占地面积最大的工艺处理设备,如何提升分离器处理效率,减少平台空间占用,节省开发成本,成为迫切需要解决的问题。本文针对某海上油田 PUQB(生产综合处理平台,B为平台代号)平台二级三相分离器进行了升级改造,在其中一台分离器上设计安装了静电聚结装置。通过与相同工况下并联运行的传统分离器对比发现,在入口含水率10%~62%工况下,传统分离器A油出口含水率为3%~36%,静电聚结改造后分离器油出口含水率可以始终保持在1%以下。同时,对静电聚结模块开展了断电测试,结果表明断电前后分离器的油出口含水率和水出口含油量变化显著,断电后分离效果明显恶化,再次说明静电聚结模块可以适应高含水工况,改造后的分离器的油水分离效果可以得到大幅提升。未来新型静电聚结原油脱水技术的进一步推广和应用,对于大幅降低工艺分离设备的尺寸和质量,降低油田开发成本均具有重要意义。
Abstract:
The separator equipment takes the largest footprint on the offshore platform. How to improve the efficiency of separator, reduce its footprint on the platform, and save the development cost has become an urgent problem to be solved. In this paper, the secondary three-phase separator of PUQB(Production Utility & Quarter,B)platform in an offshore oilfield was upgraded and modified, and an electrostatic coalescence device was designed and installed on one of the separators. Compared with the traditional separator operating in parallel under the same working conditions, it is found that for the inlet water cut of 10%~62%, the outlet water cut of traditional separator is 3%~36%, and that of the electrostatic coalescence modified separator can be as low as 1%. At the same time, the power-off test was carried out on the electrostatic coalescence module. The results show that after power-off, the water cut of separator oil outlet and the oil content of separator water outlet changed violently, and the separation effect deteriorated obviously, which further proves that the electrostatic coalescence module can be applicable to high water cut working conditions, and the oil-water separation effect of modified separator can be greatly improved. The further promotion and application of new electrostatic coalescence crude oil dehydration technology will be of great significance for largely reducing the dimension and weight of process separation equipment and saving the development cost of oilfields in the future.
