摘　　要：针对钻井生产过程随时间推移而逐渐变化的实际，提出了适于实时优化钻井的多参数钻井模型自适应跟踪算法。该方法不仅能对原来钻井模型进行实时修正辩识，而且利用计算机程序计算简便、控制精度较高。该方法是对两种递推算法的推广，特别适用于新探区建立钻井模型。文中有计算实例。To counter the practices of the gradual change of drilling process as time past, a multi parameter drilling model adaptive tracking calculation method suitable to real time optiming drilling was put forward.The method provides not only real time correction and recognition for the original drilling model,but also easy and simple caculations and high precision control with computer program.The method is the spread of two recursive formulas,which is especially suitable to establishing drilling models for new exploratory areas.There is example in the paper.
