Abstract
The aim of this study is to research the method to estimate the drillability parameters in Bohai oilfied. We recommend to use weighted correlation for grey relation clustering. The so-called grey relation clustering is to judge the similarity of comparative series (also known as sub-series) and reference series based on grey relational analysis. Generally, the more similar are the geometric shapes of them, the more similar are their change trends and the larger is their correlation degree. Clustering is conducted according to the maximum correlation degree identification principle.
