Abstract

Abstract:

Based on analysis of gauge wear and cutting structure of conventional bits and research of gauge structure of bits, a design scheme that enhances the function of active gage protection of roller cone bits is disclosed. Design, trial production and field test of the roller cone bits that strengthened the function of ac-tive gage protection were fulfilled according to the result of thstudy. The field test results indicated that the technology of enhanced active gage protection can increase the ROP of the roller cone bits.

Key words: roller cone bit, active gauge structure, Design, field test
