摘要
根据泡沫复合驱驱油机理（如低界面张力、流度控制等）和驱替过程中出现的各种物化现象（如聚合物溶液的流变性、泡沫的流变性、化学剂的吸附损耗、离子交换，碱耗及其与表面活性剂间的协同效应等）建立一个泡沫复合驱（碱／表面活性剂／聚合物／泡沫）数学模型。应用该模型可进行泡沫复合驱效果预测及其可行性研究。可模拟泡沫复合体系岩心驱替过程，进行机理研究、矿场试验设计、矿场动态模拟和动态跟踪研究等。
According to the main multicomponent foam drive mechanism (low interfacial tension, mobility control, etc.) and various physicochemical phenomena taking place in the EOR method (rheological property of polymer solution and foam, chemical absorption, ion exchange, alkali consumption, coherent effect of aldaline and surfactant, etc.), we founded a multicomponent foam drive (alkali/surfactant/polymer/foam)mathematical model. This model is very useful in simulation and study of effect predict, feasibility, the displacement process in core, mechanisms, optimal programming for field operation and dynamic simulation.
