一种复配型驱油剂的性能评价

摘要

对复配型驱油剂进行表面张力、界面张力和耐盐性测定.结果表明,复配体系在较宽的碱浓度范围(0.2％～1.8％)内,具有较高的表面活性；复配体系与胜利油田孤东采油厂油样之间的界面张力在较宽的碱浓度范围(0.2％ ～1.8％)内,具有超低界面张力.复配体系中加入NaCl和CaCl2后,采收率下降,表明复配体系的耐盐性能较差.%The surface tension,the interfacial tension and the salt tolerance were determined. The results showed that in the wide caustic concentration scope (0. 2% ～ 1. 8% ) ,the oil-expellent has the high surface activity. When added the oil sample of Gudong oil production plant into the oil displacement agent, the ultra lower bound surface tension has been found in the wide caustic concentration scope (0. 2% ～ 1.8% ). The salt tolerance was poor when added NaCl and CaCl2 into the oil-expellent.
