| 摘 要： | 通过界面张力、正交试验、吸附损失实验、室内模拟驱油实验等方法,系统研究了所合成的系列羧酸盐类Gemini表面活性剂的界面活性、与普通羧酸盐表面活性剂的协同效应、吸附损失及驱油效果.在此基础上确定了适合孤岛油田东区稠油油藏的无碱二元复合驱配方,即0.02%SDG-4+0.05%SDCM-1+0.10%SDC-1+0.2%HPAM.该配方与目的层原油的界面张力达到超低,SDG-4在油砂上的静态吸附损失为2.555mg/g,符合国家"八五"和"九五"化学驱对吸附损失的要求,室内模拟驱油实验提高采收率高达36%,具有很好的驱油效果. |

| Abstract: | Interfaeial tension,orthogonal lest,adsorption loss experiments and indoor simulated flooding experiments have been made for the systematic research of the inlerfacial activity,the synergies with the common carboxylates surfactant,the adsorption loss and the flooding efficiency of the series carboxylate Gemini surfactants. Based on this,the binary combination flooding system without alkali applied to the heavy oil of Gudao pilot site of Shengli Oilfield has been got. It is composed of 0.02wt% SDG-4(a kind o... |
| Keywords: | Gemini surfactant binary combination flooding flooding efficiency adsorption loss |
