灰色GM(1,1)模型在井壁破裂中的应用研究

Application of gray GM(1,1) model to handling shaftwall break

利用灰色GM(1,1)模型 ,把井壁破裂治理中及治理后所获得的数据视为灰色量 ,并用数列方法进行数据生成、数据拟合和数据预报 ,进而指导井壁治理工作的进展和长期维护 .算例结果表明 ,该模型具有较高的拟合和预测精度 。

Based on gray GM(1,1) model, the measured data from the handling shaftwall breaking is regarded as a gray variable.Take the advantage of the data sequence methods to produce data, data approximate and data predict, then it is used to guide the advance of handling shaftwall break and the necessary of long time maintaining. The case shows this model have high approximate and predict accuracy. It is an useful auxiliary method in managing shaftwall break.
