| Abstract: | The slipping formation is often met in drilling.Many experts have designed different types of diamond bits to solve the drilling difficult problems in slipping formation,but all these bits have their limitations.The reason of the slipping formation was analyzed.The mechanism of the use of weak package diamond bit was researched.The matrix of diamond bit was hierarchical designed.A new typical diamond bit was made.It improves the adaptabilities of bit for drilling in slipping formation. |
