新型聚结除油器在南海油气田生产水系统中的应用

为解决南海油气田生产水乳化严重所带来的常规物理分离设备难以达到良好除油效果的问题，以某气田为例，运用生产流程改进测试和数据分析的方法，研究新型聚结除油器在不同工艺流程中的替代作用和除油效果，并结合较大规模生产水系统工程对聚结除油器在工程实施过程中的综合评价进行比较。结果表明，新型聚结除油器对于乳化油具有95%以上的除油效率，并在投产后逐步显现其运维优势和经济优势。

Application of New Combined Coalescer in Produced Water System of Nanhai Oil and Gas Fields

In order to solve the problem that the conventional physical separation equipment is difficult to achieve good oil removal effect caused by the serious emulsification of produced water in Nanhai oil and gas fields, based on a gas field, the methods of process improvement test and data analysis are used, and the substitution effect and oil removal effect of a new combined coalescer in different process flows are studies .Combined with the large-scale produced water system project, the comprehensive evaluation of coalescence degreaser in project implementation is compared. The results shows that the new combined coalescer has more than 95% oil removal efficiency for emulsified oil, and gradually shows its operation and maintenance advantages and economic advantages after putting into operation.
