针对辽河油田锦１６块聚合物驱采出液的破乳脱水，在室内进行了模拟采出液和现场采出液的破乳脱水实验研究，考察了聚合物浓度（０—１０００ｍｇ／ｌ）、脱水温度（４５—７０℃）、沉降时间（０—９０ｍｉｎ）及破乳剂加量（５０—１０００ｍｇ／ｌ）等的影响，得出了聚合物驱采出液破乳脱水的一些规律。要使聚合物含量为４８０ｍｇ／ｌ的矿场采出液破乳脱水时既有高脱水率，又分离出高质量的污水，需要加入高达６００ｍｇ／ｌ的破乳剂（例如ＡＲ２２５）。
Aiming at the demulsification and dehydration of polymer flooding production fluid in Jin-16 polymer flooding in Liaohe Oilfield, the demulsification and dehydration experiments of simulated production fluid and field production fluid were conducted in laboratory. The effects of polymer concentration (0-1000mg / l) Dehydration temperature (45-70 ℃), settling time (0-90min) and the amount of demulsifier (50-1000mg / l) and so on, we got some rules of demulsification and dehydration of polymer flooding production fluid. To achieve a high dewatering rate and a high quality effluent with a polymer content of 480 mg / l demulsification, dewatering requires a demulsifier (eg AR225) up to 600 mg / l.
