摘要
Abstract
The main reasons of low drilling efficiency in elastic-plastic compact mudstone are analyzed.On this basis, a new type bit with sharp-tooth PDC was developed.The optimal design in geometric structure of PDC, cutting structure and hydraulic structure makes a good performance of the bit.Compared with ordinary PDC bits, it provides longer service life and higher drilling efficiency (average in 300m and 3~4m/h respectively) in elastic-plastic compact mudstone drilling.关键词
