摘要
修正的衰减曲线方程为三参数方程,难以直接应用线性回归分析求解,为此相继发表了多种分析方法。基于精度分析,对9种方法(三点配线法,典型曲线拟合法,诺模图法,6种线性分析法)进行了评价,并对方法的应用领域进行了初步分析,认为其中的3种线性分析法操作既简便,预测精度又高,值得在油气田产量预测中推广使用。图2表3参16(陈志宏摘)
Modified production declining curve is a 3 parameter equation and is very hard to get its solution by means of linear regression, and thus a number of different analysis techniques have been described in various papers. Based on an accuracy analysis, 9 methods (3 point linearization method, matching with type curve method, matching with a nomogram method, and 3 other linearization methods) were evaluated, and the category of application of these methods are analyzed preliminarily. It is recognized that 3 linearization methods are easy to operate with high accuracy, thus they can be generated in the prediction of future production rate of oil/gas fields.
