随着聚合物驱采油技术在油田的广泛应用,O/W含聚采出乳化污水在油气储运和水处理等方面都给现场带来了困难,研制出一种高效的含聚乳化污水的破乳剂迫在眉睫。通过实验,确定适合处理含聚浓度小于200mg/L的采出乳化污水的破乳体系,可以使采出液破乳效率达到96.08%,含油量小于2.6mg/L,满足污水回注要求。
With the widespread application of polymer flooding technology in the oilfield, the O / W poly-containing emulsified sewage has brought difficulties to the site in the fields of oil and gas storage and transportation and water treatment, and has developed an efficient poly-emulsified sewage-containing Demulsification is imminent. Through experiments, it is determined that the demulsification system suitable for processing emulsified sewage containing poly-concentrated concentration less than 200mg / L can make the demulsification efficiency of the produced liquid reach to 96.08% and the oil content less than 2.6mg / L, which meets the requirements of wastewater injection.
