新型净水剂的制备及其在高温高压SAGD采出水中的应用

Preparation of a new-type of water purifying agent and its application to the treatment of SAGD produced water under high temperature and pressure conditions

介绍了新型净水剂的制备,并用红外光谱、热重分析等方法分析了该新型净水剂的结构及热稳定性;利用该净水剂采用自制的可在高温高压下评价净水剂除油性能的装置处理呈高温、高压状态,且含油量高的超稠油SAGD采出水,考察了该净水剂在不同情况下的除油效果。结果表明:产品具有良好的热稳定性,除油性能良好,除油速度快,除油率可达99%以上。

The preparation of a new-type of water purifying agent is introduced.Infrared spectrum and thermo-gravi-metric analysis have been used for analyzing the structure and thermo-stability of the new-type of water purifying a-gent.When the self-designed equipment,which can evaluate the oil-removing capacity of water purifying agent,un-der high temperature and high pressure conditions,is used for treating the SAGD produced water which is highly oil-bearing and has extra-heavy viscosity,the oil-removal efficiency of the new-type of water purifying agent under dif-ferent conditions is investigated.The results show that the product has very good thermo-stability and both of the oil removal efficiency and oil removal speed are satisfactory.The oil remove rate could be higher than 99%.
