- 摘要:
近年来，中国大部分油田开发已进入高含水期，原油多以乳状液的形式被采出，研究原油乳状液的特性成为一个很重要的课题。运用实验方法,对中海油渤中26-3-3油田油样进行油水乳状液稳定性分析，并对不同性质破乳剂及电场的脱水效果进行了探索。通过分析研究得出:乳状液内相浓度对其稳定性的影响较大, 并且存在一个最佳内相浓度,内相浓度超过某一值时不能形成稠油乳状液；转速在500 r/min时形成的稠油乳状液最稳定,超过或低于这一转速，稳定性都会下降。
In recent years, most oilfields have progressed into high water content development stage in China. Crude oil produced from these oilfields contains a number of emulsions and investigation on characteristics and properties of crude oil lactescence has become an important topic. By using experimentation, conducted is stability analysis on oil/water (O/W) emulsions produced from Bohai 26-3 Oilfield of China National Offshore Oil Cooperation and explored are dehydration effects of different demulsifiers and electric fields. Analytical investigation results show that internal phase concentration of emulsion has large effect on its stability and an optimum concentration exists in emulsion. W/0 emulsion cannot formed if internal phase concentration exceeds certain value, heavy oil W/0 emulsion behaves most stable when rotate speed is 500 r/m and the stability will decrease when rotate speed is more or less than 500 r/m.
