Abstract:

The main failure form of V-round-thread casing, that is, the mechanism of thread connection slipping off，is analyzed in this paper. In the process of analysis，some new knowledge of threaded connection slipping is obtained and new failure mechanism of slipping is suggested，which is valuable to studying casing's threaded connection slipping and preventing it from slipping in cementing engineering.
