钻杆胶箍是减少钻杆、套管磨损的一项好经验,我队从57年下半年已全面推广使用.多年的生产实践证明:在摩擦性较大的岩层上钻进,钻杆的使用期限能延长3倍以上,同时也减少了钻杆的折断事故,因而对提高效率、降低成本起了一定的作用.还由于胶箍在孔内也起到活动轴承和导正钻杆的作用,从而减少了孔斜.钻杆胶箍的加工和技术要求如下表所示:
Drill pipe rubber hoop is a good experience to reduce the wear of drill pipe and casing. Our team has been widely promoted in the second half of FY57. The production practice for many years has proved that it is drilled on the rock layer with large friction and drill pipe. The service life can be extended by more than 3 times, at the same time, the broken drill pipe accident is also reduced, which has played a certain role in improving the efficiency and reducing the cost. Also, the rubber hoop also plays a role in moving the bearing and guiding the drill pipe in the hole. , thus reducing the hole inclination. The drill pipe hoop processing and technical requirements are shown in the following table:
