摘　　要：将VB与Matlab结合,用于钻井事故诊断系统开发,通过钻井现场所得的数据样本,用曲线拟合与人工神经网络技术,设计实现钻井异常数据诊断系统。文中介绍了VB调用Matlab的详细步骤,利用Matlab的图形处理及神经网络训练优势,结合VB良好的图形用户界面,用程序段的方式说明用VB编写主界面,Matlab完成曲线拟合与神经网络诊断的具体实现过程。利用此方法缩短了程序开发时间,减少了程序开发工作量。经实践证明,该方法切实可行,对钻井生产具有指导作用。Combination of VB and Matlab is used to develop the drilling falure diagnosis system which is realized through curve fitting and artificial neural network technique with data samples obtained at drilling site.The paper introduces detailed procedures that VB transfers Matlab and the implementation process of diagnosis that VB writes the main interface and Matlab completes curve fitting and neural network.This method shortens program development time and reduces program development workload.It is proved through experiments that the method is feasible and has instructional effect in drilling production.
