大庆油田实施聚合物驱油以后,使得含有聚合物原油采出液形成了稳定的乳状液,采用常规破乳剂已无法解决破乳脱水的难题,严重影响了原油脱水生产和商品油的质量。针对生产中这一难题,在室内通过采用不同分子结构破乳剂,并根据“协同效应”原理,研制出了FPW320破乳剂。室内经用不同聚合物含量的原油乳状液破乳脱水效果表明,提高了破乳速度,降低了脱后污水含油量,并且减少了乳化层的产生。该剂经在大庆油田最大的聚合物驱原油采出液处理站──北十三联合站推广使用,在原油采出液中聚合物含量90-130mg/L,破乳剂用量每天可节约200kg以上,脱后污水中含油量降低了100mg/L,降低电脱水器电流40mA,并且解决了电脱水器的波动,烧硅片、保险等影响脱水生产的难题,保证了原油脱水生产的正常运行和商品油质量。
After polymer flooding is implemented in Daqing Oilfield, it makes the polymer crude oil production liquid form a stable emulsion. The problem of demulsification and dehydration can not be solved by conventional demulsifier, which seriously affects the quality of crude oil dehydration production and product oil. For the production of this problem, through the indoor use of different molecular structure demulsifier, and in accordance with the “synergies” principle, developed the FPW320 demulsifier. The effects of demulsification and dehydration on crude oil emulsions with different polymer contents indoors showed that the demulsification rate was increased, the oil content of the treated wastewater was reduced, and the formation of emulsion layer was reduced. The agent in Daqing Oilfield largest polymer flooding crude oil production fluid processing station - North 13 joint promotion of the use of crude oil production fluid polymer content of 90-130mg / L, the amount of demulsifier can save more than 200kg per day , After taking off the oil in the sewage reduced 100mg / L, reducing the electric dehydrator current 40mA, and solved the electric dehydrator fluctuations, burning silicon, insurance and other issues affecting the production of dehydration to ensure the normal operation of crude oil dehydration production and Product oil quality.
