摘 要:
目前用于矿场注聚效果评价的Hall曲线是一条累积曲线，对注聚动态不敏感，据此难以及时准确地进行注聚效果早期评价。提出了Hall导数曲线法。Hall导数与吸水指数互为倒数。实例应用表明，Hall导数曲线法是一种更具敏感性的注聚效果评价方法，保留了Hall曲线法的功能，弥补了Hall曲线法的不足。[著者文摘]

Abstract:
As a cumulative curve, the Hall curve used to evaluate polymer flooding effects in fields currently is not sensitive to flooding performance, and is difficult to get early evaluations accurately and timely. Therefore, a method of Hall Derivative Curves is proposed, in which the Hall derivative and injection index are inverse each other. The applications have shown that it is a more sensitive method to evaluate polymer flooding due to its retaining the functions of Hall curve method and compensating the shortcomings of Hall curve method.[著者文摘]
