摘要/Abstract

摘要： 对无限大天然裂缝油藏试井资料的曲线拟合问题,给出了一套理论图版的计算公式,并采用双重误差控制法与对数搜索法进行理论曲线的搜索,从而使试井资料的曲线拟合实现了自动化,极大地提高了拟合速度和精度.大量计算实例表明,这种方法不仅计算速度快,而且相应的软件使用十分方便灵活,对均匀介质和双重介质都实用.

Abstract: A computational formula of the theoretical curve for the curve fitting of well testing material of infinite naturally fractured reservoir is proposed. The double error control method and the logarithm searching method are used to seek the theoretical curve. A lot of experiments show that this method is with high precision and rapid calculating speed.

Key words: naturally fractured reservoir, curve fitting
