| Abstract: | Based on the theoretical analysis, a new type of blade bit was invented. And this kind of bit combines the advantages of PDC bits and drag bits. And a series of field experiments were performed. The experimental results show that the bit can be used under low WOB and high rotary speed. Its high stability and reliability, great drilling speed, remarkable incline prevention, and the smooth wellbore show that this bit is worth being popularized for its expectable great economic and social benefits to drilling industry. |
