摘要
在直线拟合最小二乘法线性回归的基础上,研究了针对Arps产量递减分析的计算机自动拟合方法。该方法能够快速、准确地确定递减参数(Qi、Di、n)并进行产量预测,从而解决了手工试凑费时、费力且精度不高的问题。文中给出了具体的实现原理及步骤,并编制了计算机应用软件,最后在研究的自动拟合算法及应用软件的基础上,给出了实际油田应用的实例。实践证明,该方法的效果很好。
Based on the least square linear regression ,a computer method of automated matching was studied for Arps production decline.This method can determine decline parameter Qi,Di and n quickly and accurate- ly,and make a prediction of hydrocarbon production ,thereby avoiding manual trials consuming time and cost and having a low accuracy.In this paper,the specific principles and procedures are given for the method,and its application software of computer is programmed.Finnally,the oilfield examples with application of the method and software are described,indicating that the methed is satisfactory in its effects.
