摘要
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）。
The reuse of the produced water from a polymer flood industrial test area in Daqing is investigated through laboratory EOR simulation experiments on artificial cores. It is shown that in comparison with fresh water flood, flood by a produced water of low polymer concentration C p=80 ppm (of viscosity 0.75 mPa·s at 45℃) enhances oil revovery very little and flood by a produced water of C p=370 ppm (of 3.00 mPa·s at 45℃) - by 12% more; 1000 ppm polymer solution in the produced water of 0.75 mPa·s drives out as much residual oil as 1000 ppm polymer solution in fresh water does and an enhancement of ～20% is observed in both cases.
