摘　　要：应用地质统计学和分形几何学，提出了一种井间砂体的预测方法，该方法利用克立格插值场对储层进行大尺度的趋势估计，储层小尺度的变异特征则利用随机分形场来刻划。然后对生成的二维克立格插值场和随机分形场进行叠加处理得到预测结果，实例研究表明，对于砂岩储层，应用该方法进行井间砂体分布模拟可以定量判断井间砂体分布，误差分析表明模拟结果具有较高的可信度。A new method of forecasting the sandbodies between wells by application of geostatistics and fractal geometry is proposed in this paper.This method could be used to estimate reservoir variation tendency in large scale by Kriging interpolation field,to describe reservoir variation property in small scale by stochastic fractal field.Then 2 D Kriging interpolation and stochastic fractal fields were stacked so as to obtain the forecast result.The study of an example shows that this method could be used in sandbody distribution simulation,the result is reliable.
