摘要
Abstract
The small-diameter directional drilling is an important technology to solve the problem of high-precision ore-controlled exploration and drilling.In view of the broad-spectrum adaptability of the PDC bit in small-diameter directional drilling construction for the hard rock with thin and soft interbed in the Lanling iron ore area,through the optimization design of the crown shape of the drill bit,the blade arrangement,the PDC cutting tooth inlay welding angle,the hydraulic structure of the drill bit and the drill bit carcass,the Ø98 mm directional drilling PDC bit was developed.After the application verification of three directional drilling holes in heterogeneous strata above medium hardness,the PDC drill bits have achieved satisfactory results in impact damage resistance,wear resistance,service life,etc.,achieving the goal of efficient rock crushing and continuous and stable directional drilling,which provids an effective solution for the design and manufacture of small-diameter directional drilling PDC bits.关键词
