双曲线递减参数求解的新方法

A NEW METHOD FOR SOLVING HYPERBOLIC DECLINE PARAMETERS

基于对Ａｒｐｓ双曲递减方程及参数求解各方法的研究，提出了一种新的线性求解方法，只需两次简单的线性回归，即可求得参数ｎ、Ｑｉ、Ｄｉ。该方法适用于时间等步长、非等步长取值条件下的递减分析，具有简单方便的特点。经实例验证，是可靠有效的。

On the basis of the research on the ARPS hyperbolic decline equation and the various methods of solving parameters,a new linear solving method, which only needs twice simple linear regressions in order to abtain parameters,n,θi,Di,is raised. This method is suitable for the decline analysis of taking values under conditions of equal time steps and unequal ones and has features of simplicity and convenience.It is reliable and effective by verification of case histories.
