摘要
以往一般采用单项参数或者将各层的储层参数罗列在一起评价储层层间非均质性,未将多参数有机地结合起来,形成“量”的概念,因此,有必要对传统方法进行发展和创新。本文应用多种储层参数,求取其综合评价值,采用数理统计方法,定量地评价了储层层间非均质性。采用该方法的描述结果与已取得的地质认识是相符的。
Reservoir interlayer heterogeneity was usually evaluated by single parameter or by simply putting various parameters of each layer together in the past. Different parameters aren' t integrated organically lacking of quantitative concept in these traditional methods. Therefore, it is quite necessary to improve traditional methods to make technical innovation. Multi-parameters of reservoir and mathematical statistical method are used to calculate an overall evaluation value, which is enabled to evaluate the reservoir interlayer heterogeneity quantitatively. The result of quantitative description has a perfect fit with the geological knowledge before.
