摘　　要：采用荧光法测定了辽河油田曙光采油厂170 2井特稠油乳化HLB值。以混合型表面活性剂、阴离子型表面活性剂及非离子型表面活性剂为主剂,快速渗透剂及碱助剂等为辅助剂,按一定比例合成了水基降粘剂SGVR - 1。室内实验结果表明,该降粘剂具有良好的乳化降粘性能(降粘率不低于99% )、自动破乳脱水性能和配伍性能(与破乳剂) 。The HLB value of super heavy oil emulsion from well 1702 in Shuguang, Liaohe oilfield is measured by fluorescence method. SGVR-1 water-base viscosity reducer is made at certain proportion with mixed type surfactant, anionic surfactant and non-ionic surfactant as main agents and with fast permeable agent and base agent as auxiliary agents. In-house experiment shows that this viscosity reducer has good properties of emulsifying viscosity reducing (the reducing rate not less than 99%), automatic demulsification and dehydration, and compatibility (with demulsifier). It is a suitable water-base viscosity reducer for super heavy oil.
