驱油泡沫稳定剂的性能研究

在硫酸盐起泡沫中添加4种不同类型的增粘性稳泡剂后，用Waring Blender法评价了起泡沫的起泡情况以及不同稳泡剂的稳泡效果，利用布氏粘度计对4种稳泡剂溶液粘度的测定，从而了解了不同稳泡剂溶液随温度的升高和盐度的增大其粘度降解的情况，在此基础上，优选出了疏水缔合聚合物及其最佳加量，实验结果表明：添加了疏水缔合聚合物稳泡剂的起泡液具有在较高温度和矿化度下起泡能力较强且所起泡沫半衰期较长的优点，在油田EOR过程中注泡沫体系中具有良好的应用前景。

Properties of Stabilizers for Foam Flooding

The foamability of sulfate foaming agent and its stability has been evaluated by a Waring Blend Method when adding respectively four types foam stabilizers. The viscosity decrease of the four foam stabilizers solution with the increase of temperature and salinity has been investigated. And hydrophobically associating polymer and its concentration are optimized. Results show that the foam solution in which the hydrophobically associating polymer is added has stronger foamability and its foam has longer half life. It has good applied prospects in foam flooding.
