Abstract:

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.
