| Abstract: | This paper proposes improving measures according to the problems in the procedure of drilling the blue bind formation using the three-winged drag bit. It also discusses the problems such as striping away the protector, changing the shape of the vice flushing hole, altering the degree of the hook angle and the arrangement of the cutting prongs. The paper solves the two problems of gummed in and low drilling speed. |
