The calculation of curving intensity while drilling with operated rotor systems

Abstract

One of the recent achievements in the field of the systems of operated rotary wing providing fast increase of curving angle is a hybrid system combining the characteristics of the systems of control and deflection of axe. There are several theoretic methods of calculation of curving intensity іα. The first of them is a method of using the depth by the vertical h and by horizontal s. In this method curving radius R is considered permanent (i.e. it changes along the circle arch). The second method of calculation of curving intensity is a three-pointed technique, which can be applied for the drilling with a curved casing and with the systems of “Point the bit” as they are operated with similar mechanisms.
