摘　　要：利用测井数据进行井内物理地质描述是测井勘探时常用的手段,但是测井数据经常会出现缺失,所以测井曲线的复原一直是石油勘探领域迫切解决的问题。该文提出了一种基于多种树模型融合的方法,利用Stacking集成方法融合模型,对井内的多条测井曲线进行复原。实验结果表明,通过多模型融合方法的复原结果优于单一树模型,该方法具有更小的误差和更高的精度。A Method of Logging Curve Recovery Based on Multi-model Fusion Using logging data to describe physical geology in well is often used in well logging exploration,but the problem of missing logging data often occurs.So the restoration of well logging curve has always been an urgent problem in petroleum exploration.In this paper,a method based on the fusion of multiple tree models is proposed,and the multiple logging curves in the well are restored by using the fusion model of Stacking integration method.The experimental results show that the recovery results of the multi-model fusion method are better than that of the single tree model,and the proposed method has smaller errors and higher precision.
