在油田污水处理中,含聚污水的处理是油田持续发展和开发技术进步带来的新课题。聚合物驱采出液是复杂的混合乳化分散体系。相对于水驱采出液,聚合物驱采出液中的活性组份中的活性物质分子更加复杂,增加了界面膜的强度,提高了聚合物驱采出液W/0型乳状液稳定性。含聚污水具有乳化程度高,油水分离时间长的特点。因此,常规污水处理工艺在含聚污水处理上出现了适应性差、处理后水不达标的实际问题,为提高含聚污水处理效果,孤东采油厂进行了多方面的探索,围绕高效污水处理药剂、气浮处理技术、离心机和污水处理配套技术开展研究,提出了技术思路。
In the oilfield wastewater treatment, the treatment of poly-containing sewage is a new issue brought by the continuous development of oilfields and the development of technological advances. Polymer flooding fluid is a complex mixed emulsion dispersion system. Relative to the water flooding production fluid, polymer flooding the active component of the active component of the fluid recovery of the more complex molecules, an increase of the strength of the interface membrane, polymer flooding recovery solution to improve the stability of W / 0 emulsion . Containing polywaters with a high degree of emulsification, oil and water separation for a long time characteristics. Therefore, the conventional sewage treatment process has appeared in the poly-containing sewage treatment adaptability is poor, the actual treatment of water does not meet the actual problem, in order to improve the effect of poly-containing sewage treatment, Gudong Oil Extraction Factory conducted a wide range of exploration, centered around the efficient sewage treatment chemicals , Flotation processing technology, centrifuge and sewage treatment technology to carry out research and proposed technical ideas.
