摘要

随着油气藏整体压裂技术的发展,压后评估技术越来越受到广泛重视。针对压裂后压力递减资料分析技术,提出了一种新的数学拟合方法,并研制了一套Windows环境下的解释软件、应用该软件可以获得压裂后的有关评价参数。实例计算表明,本方法比传统的曲线拟合方法更为简便可靠。

Abstract

With the development of whole fracturing technology for gas reservoir, more and more importance is attached to the post-fracturing evaluating technology. This paper introduces a new mathematical fitting method and develops a set of computer software for Windows, by which we can obtain the relevant parameters for post-fracturing evaluation.Some field examples show that the new method is simpler and more reliable compared with the conventional curve fitting method.
