摘要
本文综述了近年来国内外在化学复配体系提高石油采收率研究中的最新成果。报导了碱(A)/聚合物(P)二元及碱(A)/表面活性剂(SF)/聚合物(P)三元复配体系的界面张力(IFT)、粘度(μ)、碱耗、化学剂的吸附滞留、活性图等方面的工作。对这类体系的驱油机理和高采牧率低费用的原因进行了初步探讨。介绍了复合驱油的三个现场试验。
The recent developments in binary(alkaline/polymer,AP)and ternary(alkaline/sur- factant/polymer,ASP)combined chemical flooding systems for EOR are reviewed in this article.The oil/water interfacial tension,viscosity,alkaline comsumptiou,adsorption and retention of polymer and surfactant,tendency,field tests and economical perspec- tive for the two classes of combined systems are presented.The role of“activity map” method in formulating ASP systems is introduced,in particular.Some comments about chemical EOR in China are suggested.
