灰关联分析在储层评价中的应用

Application of grey association analysis in reservoir evaluation

介绍了灰色理论中的灰关联分析方法 ,并利用此方法以东营凹陷碎屑岩储层评价研究为例 ,确定了影响该地区储层质量评价指标的权重大小 ,使得进行储层评价时更加符合客观实际 ,可信度更高。应用实例亦证实 ,灰关联分析法计算简便 ,运算速度快 ,所需数据量小 ,可确定单项指标定量化标准、各项指标参数的权重、确定综合权衡评价分数和分类标准。值得推广应用。

This paper introduced the principles and methods of grey association analysis and its uses in the evaluation of the Paleogene clastic reservoirs in Dongying depression. The weight coefficients of evaluation indices that control reservoir quality were determined by grey association methods, making the reservoir evaluation more objective and credible. Case study indicates that grey association methods are fast and simple in calculation, involve small quantity of data, and therefore are worthy to be popularized.
