GRAY CORRELATION ANALYSIS METHOD OF ON-LINE FAULTS DIAGNOSIS IN DRILLING
Liu Ruiwen · Drilling & Production Technology · 2004
In most cases, there will be corresponding signal phenomenon before drilling trouble occur. The time interval from phenomenon appears to trouble occur is very short. Therefore, using correlative theory and methods of fault detection and diagnosis can prevent drilling trouble. This paper introduced the method of on-line faults diagnosis by using gray correlation analysis method.
