| Abstract: | To solve the problem of drill stem joint's frequent tightening and unload in drilling process and its intension decreases in processing whorl,using the technique-laser rigidification technique to enhanced its capabilities. The test shows that the capabilities of drill stem joint surface such as hardness,abradability and fatigue resistance,were improved. Drill stem joint life-span can be enhanced with the method,and it takes little time and fewer workers. |
