| 摘 要： | 利用注采特征曲线计算开发指标和析油藏动态,具有需要数据少、计算简单、计算精度高的特点,因而已成为稠油注蒸汽开采的常规分析方法.但实践资料表明,早期的注采曲线是一条曲线,只有生产时间较长、出现直线段后才可利用计算,否则会出现较大的误差.本文提出了注采特征曲线的早期曲线部分的校正方法,扩大了其应用范围.

| Abstract: | It is a simple and accurate method to compute development index and analyze reservoir performance by injection-recovery history curve, so that this is a conventional method used in heavy oil steam drive. However, practical data shows that, early injection-recovery history is a curve, and only the straight line section, which appears after long production time, can be used for computing, otherwise there would be larger errors. This paper presents a correction method for early injection-recovery history, and expands the application range of the curve. |
