Cokriging法在某地Sz36-1油田中的应用

Application of Cokriging method in Sz36-1 oil field

本文阐述了由孔隙度面函数和储层间隔传播时间面函数，构造孔隙度线性均方估计算子。由数据矢量和Cokriging矩阵求得储层孔隙度的空间分布，并列举了Cokriging法在某地Sz36－1油田中的具体应用。

This paper expounds how to construct linear mean-square operators for estimating porosity based on a porosity's surface fUnction and a reservoir's interval traveltime surface function as well as the derivation of the porosity,s spatial distribution over reservoirs using data vectors and a Cokriging matrix. The application of the Cokriging method in Sz36-1 oil ficld is also covered.
