Improvement of method of bottom hole assembly calculation via elastic centralizer

A.F. Ravanov

The article presents improved method of bottom hole assembly calculation via elastic centralizer. It is shown that for different type sizes of this sort of assembly, there is a permanent location for installation of centralizer providing less intensive composition regardless of value of well current zenith angle. In the result of conducted calculation by improved method it was established that after the 700 of zenith angle, the rate of deviation force takes minimum value. This fact indicates permanency of deviation force values in significant zenith angle indexes.
