发明名称 High pressure hydraulic testing packer
摘要 A resilient packer that may be mounted on a high pressure hydraulic testing unit to permit the unit to be moved axially through a string of tubular members connected end to end by collars. The tubular members have flat ring-shaped end surfaces that are disposed as pairs within the collars connecting the tubular members. The end surfaces of each of the pairs are longitudinally spaced a substantial distance. The packer is of such structure that a portion thereof is radially compressed into fluid sealing contact with the interior surface of the tubular member in which it is disposed, but which packer will not hang up on one of the end surfaces when it traverses the longitudinal space between a pair thereof as the testing unit is axially moved through the string of tubular members.
