摘要
针对大庆油田部分聚合物驱区块含油污水油水分离难度大的问题 ,从阴离子型和非离子型药剂的思路出发 ,研发了对聚合物驱采出液有良好破乳作用且对聚合物驱含油污水有浮选除油功能的油水分离化学剂 ,提出了将油水分离化学剂的加药点设在聚合物驱采出液破乳之前 ,加药量 2 0mg/L ,采用热化学沉降—浮选处理工艺 ,使采出液中油的质量浓度从 15 0 0mg/L降到 30mg/L以下。
An oil/water separation agent,formulated mainly with nonionic and anionic active components,was developed for polymer flooding produced liquid and oily water.The newly developed oil/water separation agent works well both as demulsifier for O/W type polymer flooding produced crude oil emulsion and as floatation agent for polymer flooding produced oily water.Based on the performance of the newly developed oil/water separation agent,a thermo chemical settling floatation process,in which the newly developed oil/water separation agent is injected into polymer flooding produced liquid upstream of free water knock out,was proposed for the oil/water separation of polymer flooding produced liquid and oily water.
