磨损性

To cooperate with new and old parts: although standard zero, components, but in between interchangeable in assembly parts, and to make the optimal coordination between trim, still needs a lot of work, such as the gear and rack, boring if after removal of gear various performance indicators are used by detecting without the need to change, and to replace worn rack, rack and rack positioning pin hole on installation bolt holes and should be first, reoccupy hand crossed positioning drills and tapered reamer to match the drill and match hinge, and after the installation of new and old super-modulus gear mesh clearance to achieve technical standards, this work takes about one day.

。新，旧零部件重新配合过程：尽管标准零，部件间具有互换性，但在装配中，要使新旧零部件间的配合达到最佳状态，仍需大量的修整工作，如镗床的齿轮与齿条，若拆卸后齿轮的各项性能指标经检测尚能使用不需更换，而齿条磨损严重需更换，那么齿条及齿条安装面上的定位销孔和定位螺钉孔就需先划线定位，再用手电钻及锥形铰刀重新配钻和配铰，且新齿条安装完毕后与旧齿轮的啮合间隙需达到技术要求的标准，此项工作需时约一天。

Be living in the deep well ultradeep well prospecting process ,Since radial direction force 、Eddy is stird 、Elements such as horizontal vibration and so on being ,In the wake of well drilling time the increase ,The auger post writings is used the casing inside wall crossrange strenuously to broaden ,It is more and more grave to cause casing and drilling rig to join the wornout problem .

论文摘要：在深井超深井勘探过程中，由于径向力、涡动、横向振动等因素的存在，随着钻井时间的增长，钻柱作用于套管内壁的侧向力增大，导致套管和钻具接头磨损的问题越来越严重。造成钻具耐磨带失效的主要原因有地层研磨性、钻杆的井下工况、耐磨材料选择与
