随着新疆风城超稠油规模开发，SAGD 开发方式被广泛用于油田生产，该部分采出液进入常规稠油处理站后，造成原油脱水困难，并导致出水指标恶化，给油水处理系统的平稳运行造成很大冲击。为解决 SAGD采出液油水处理难题，CPE 新疆设计院通过大量室内研究和动态模拟试验，初步确定了“气液分离、高效预脱水、高温正向破乳”的 SAGD 采出液高温密闭处理流程，辅以“预脱水剂、正向破乳剂”的药剂体系，以确保SAGD 采出液在低粘度、高密度差的最佳工况下实现油水高效分离。根据风城油田30×104 t/a 规模 SAGD 采出液处理站建站初期现场试验情况，通过试验数据分析，对室内研究结果进行工业化验证，同时为该站生产运行提供数据支持。

With scale development of Fengcheng super heavy oil in Xinjiang Oilfield, SAGD development mode has been widely used in oilfield production. In the production, part of the produced fluid is piped to the 1st heavy oil treatment station, which can result in the difficulty of crude oil dehydration in the station to make the sedimentation tank effluent index worse, to cause great impact on the smooth operation of water treatment system. In order to solve the water treatment problems, through experimental research and dynamic simulation, Xinjiang institute initially established a high temperature sealed dehydration process of "gas-liquid separation, efficient pre-dehydration and high temperature demulsification", supplemented by "pre-dehydrating agent and demulsifier" the agent system. The process can ensure efficient separation of oil and water in SAGD produced fluid under optimum conditions. In this paper, based on field test of 30×104 t/a SAGD produced liquid treatment station, through test data analysis, industrial test of the process was carried out.
