HELICALLY WOUND EXPANDABLE TUBULAR INSERT

摘要

The present invention provides a connector arrangement for connecting a firs t tubular to a second tubular. In particular, the present invention relates to a method for connecting tubulars in such a way that the connection is prevente d from becoming unmade in response to expansion of the tubulars in a wellbore. More particularly, the present invention provides a tubular connection using a helical or spiral thread insert to seal and maintain mechanical strength in a tubular connection after expansion.
