Abstract:

In this paper,the fuzzy cluster analysis method is used to discuss the classification of formations under some of their lithologies.17 kinds of formation having been used to illustrate,their fuzzy contain matrix is set up and their classification diagram is drawn.The bit selection is discussed according to the lithologies of the formation drilled.


Key words: Bit, Selection, Formation, Lithology, Fuzzy cluster analysis
