虚拟变量模型在油田钻井类物资需求预测中的应用

The Application of Virtual Variables Model in the Forecasting of Material Demand and Supply in Oil Field Drilling

介绍了虚拟变量预测模型基本原理,阐述了模型及影响变量选择过程,以一种管材为例,详细分析了虚拟变量模型构建过程,并对其精度和显著性进行了检验,结果表明该模型预测性较好。

This paper introduces the basic principle of a forecast model of the virtual variables, and illustrates the process of selecting the model variables. Finally, take a kind of pipe for instrace, the process of construction of virtua variable＇ model is analyzed. Its accuracy and significant is tested. The result shows that the predictability of the model is good.
