Abstract

To solve the problem of drilling difficulty of hard strata in China’s Yumen Oilfield and so on, torsional impact drilling tools are widely used in the field. This paper mainly describes the reverse design process of 8½ torsional impact bit, to coordinate the torsional impact drilling. Through establishing bit CAD parametric model, analyze the model deviation and curvature, to rationally adjust the design parameters, so that obtain the bit entity model. At last, we recommend applying Pro/ENGINEER for local adjustment of bit tooth arrangement, and describe the main features of the drill bit.
