通过研究水驱油水井压力与三元复合驱油水井压力区别，发现由于聚合物的黏弹性等原因致使三元复合驱中所测得油水井静压与实际值有显著偏差，从而使在水驱时正常使用的评价油水井生产能力的指数不能直接套用在三元复合驱中。通过研究提出了基于目前测试水平下的计算三元复合驱的吸水指数和产液指数公式，由此得到比吸水指数和比产液指数公式，并进行实例计算，结果表明新公式的计算结果较原有公式更加合理。

By studying the difference of well bottom - hole pressures between ASP flooding and water flooding,it was found that due to polymer viscoelasticity,the formation pressures tested for injectors and producers in ASP flooding were actually different from the actual ones. As a result,the injectivity and productivity indices of water flooding were unsuitable for ASP flooding. So a novel equation for calculating indices of the injectivity and productivity per unit meter was proposed under the current test conditions. The calculating results of the actual case were more reasonable than the existing equa-tions.
