摘要
水平井产量递减类型的准确判断是制定水平井开发方案的重要参考依据,为水平井开发合理化和科学化提供了重要基础。本文以阿普斯递减模型为基础,利用图解法研究了判断水平井产量递减类型的过程,最终得到了递减指数n=0.5的双曲递减公式能较好地拟合水平井产量递减趋势。最后,用实例验证了该公式能够较好的预测水平井开发动态。
Accurate judgment for the production decline type is not only an importance decision-making gist to draft development program for horizontal well, but also offers an important foundation for reasonably and scientifically developing horizontal well. Based on Arps decline model, we studied the process for judging the production decline type for horizontal well by graphic method. The conclusion was drawn that the Arps hyperbolic decline equation(n=0.5) was suit for describing production decline tendency of horizontal well. Finally, the conclusion was proved by practice.
