井间砂体定量预测一直是人们关注的热点问题。本文给出了一种简便的预测方法－加权滑动平均法，分析了该方法的原理及各项参数的意义，同时给出了预测砂体的计算步骤。采用交叉验证的方法检验了这种方法的可行性及适用性，并同距离平方反比法和克里格法进行了比较。结果表明，采用本文给出的预测方法，计算简单，快捷，便于计算机实现，且能够达到比较高的预测精度。
Quantitative prediction of interwell sand body has been a hot issue of concern. In this paper, a simple and convenient method of prediction, weighting moving average method, is presented. The principle of the method and the significance of each parameter are analyzed. At the same time, the calculation steps for predicting the sandbody are given. The feasibility and applicability of this method were tested by cross-validation method and compared with distance inverse square method and Kriging method. The results show that using the prediction method given in this paper, the calculation is simple, fast, easy to implement by computer, and can achieve high prediction accuracy.
