-
摘要: 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。Abstract: For quantitatively predicting sandbody thickness among the wells, this paper provides a simple method-weighted sliding average method, expounds the principle of method and the meaning of several parameters, and gives the procedure of prediction. The calculated result shows that predicted accuracy is higher.
