摘要
针对风城油田高含水稠油采出液现有的脱水集输工艺存在需外加化学破乳剂、脱水时间长、柴油用量大和回收能耗高等问题,对稠油采出液进行脱水实验研究.实验结果表明,采用自制的SW-脱水剂,在加入20％质量分数SW-Ⅰ、脱水温度90℃、脱水时间14 h条件下采出液含水率从80％降至0.48％,脱水率99.40％;脱水后采出液在130～150℃常压蒸馏回收脱水剂,脱水剂回收率99.60％,采出液含水率降至0.27％.测定含20％脱水剂的脱水稠油的粘度表明,其在60～90C管输温度范围内的粘度仅为掺入25％柴油脱水稠油的50 ％～64％.提出了风城油田稠油采出液脱水的原则工艺流程.
Having the experiment on removing water from produced liquid from Fengcheng oilfield because of the existing dehydration method has many disadvantage such as requires additional demulsifier, long reaction time, high dosage of diesel and high energy consumption for recycling it. The results indicated that concentration of 20 % homemade dehydrant SW-Ⅰ was the best dehydrating agent. Under the conditions of reaction temperature 90 ℃, reac-tion time 14 h, the moisture content of the produced liquid can be reduced from 80 % to 0.48 %, the dehydrating rate was 99.40 %. Under the conditions of reaction temperature 130-150℃, reaction time 2 h, the recycling of dehydrating agent was conducted by atmo-spheric distillation, and the recycling rate was 99.60 %. During the process of recycling, the moisture content of the produced liquid can be reduced from 0.48 % to 0.27 %. The viscosi- ty of dehydrated produced liquid which contains 20 % SW-Ⅰ under the pipeline tempera-ture（60-90 ℃ ） indicates that its pipeline mobility is better than dehydrated produced liquid which contains 25 % diesel. At last, proposed a technology process on removal of water from produced liquid.
