开发出了适合辽河油田冷家堡特稠油和胜利油田孤岛特稠油的ＧＬ系列乳化降粘剂，对其Ｏ／Ｗ型乳状液流变性进行了研究。由这两种特稠油制备的乳状液的流变性具有较大差异。剪切速率在５０～８００ｓ－１范围内，对于辽河特稠油乳状液，当其内相浓度低于２８％时呈牛顿型流体状态，高于３０％时呈胀流型流体状态；对于孤岛特稠油乳状液，当其内相浓度低于２８％时呈牛顿型流体状态，高于３０％时呈假塑性流体状态。剪切速率增加到约８００ｓ－１后，两种乳状液（即使内相浓度高达７１％时的辽河特稠油乳状液）呈现牛顿流体状态。
Developed the GL series emulsion viscosity reducer suitable for Lengjiapu extra-heavy oil in Liaohe Oilfield and isolated heavy oil in Shengli Oilfield, and studied the rheological properties of O / W emulsion. The rheology of emulsions prepared from these two very heavy oils is quite different. Shear velocity in the range of 50 ~ 800s-1, for the Liaohe extra-heavy oil emulsion, when the internal phase concentration of less than 28% when Newtonian fluid state, above 30% was dilapidated fluid state; for islands Extremely heavy oil emulsion, when the internal phase concentration is less than 28% Newtonian fluid state, above 30% was pseudoplastic state. After the shear rate was increased to about 800 s-1, the viscosities of the two emulsions, Liaohe extra heavy oil emulsion even at an internal phase concentration of 71%, appeared in a Newtonian fluid state.
