螺杆钻具台架试验与现场使用的效率分析

The Screw Dill Efficiency Analysis on Bench Testing and Using

通过对螺杆钻具台架试验效率与现场使用效率的对比分析，论述了螺杆钻具在台架试验时一些测试数据的修正方法和评判螺杆钻具实际工作时性能优劣的方法与概念，意图对螺杆钻具的生产和装配操作提供参考。

Abstract By correlatively analysing the efficiency of the screw drill on bench testing and using in the hole,some methods of correcting the data obtained from bench test and some methods or ideas appraising using properties of the screw drill are given.We want to give some advice to the manufacture of the screw drill.
