Abstract: This paper presents the results of chemical flooding simulation for different situations by using the model established in the preceding part (No.1,1988).The simulator has been verified by good consistence of calculated results with experimental ones,to have the powerful ability to describe practical problems and work normally.Various simulations were Then perfoimed under field conditions for studying the effects on the oil recovery of different factors (such as composition and size of the additive slug,rate of injection,additive dispersion and adsorption,gravity,reservoir heterogeneity,fluid compressibility,injection/production method).The application demonstrated that the simulator is a very useful tool for analyzing mechanisms,forecasting pilot study performance,making project feasibility study,optimizing injection/production conditions,defining the working scheme etc.

摘要： 本文利用在上部分(《石油学报》1988第一期)中建立的化学驱组分模型,对多种情况下的化学驱油算例进行了模拟计算。首先与实验结果进行了比较,计算结果与实验结果取得了较好的一致性,表明了模型描述实际问题的能力及正常的工作性能;进而对现场条件下的驱替试验例子进行了模拟预测,并对各种因素(如表面活性剂段塞组分与尺寸,注入速度,活性剂的扩散、吸附,重力,油藏非均质性,流体压缩性,注采方式等)对驱油特性的影响作用进行了分析研究,给出了各自的影响效应。模型的使用表明,它对于各种机理性研究.现场试验特性预测,方案的可行性研究,各种参数的优化选择,驱替方案的制订等将是一个非常有用的工具。
