Oilfield lift cap and combination tools

摘要

A modular tool body having upper and lower sections, a pair of longitudinal members define a central open region, the longitudinal members joined at one end having a lifting feature formed therein configured to accept a manipulator. The lifting feature is positioned such that when the modular tool body and a rig tool connected thereto are lifted by the manipulator, they are easily moved over, aligned with, and connected with a working drillpipe or other rig tool while minimizing possibility of the manipulator slipping off. The lower section includes a threaded end mating with a mating end of a rig tool, a central longitudinal bore, and an upper end formed to accept the lower ends of the longitudinal members of the upper section. Elongate slots in each longitudinal member define one or more manipulating handles. A pair of generally horizontal hand holds may be formed in each longitudinal member.

主权项

1. A modular tool body comprising:
a one-piece, formed, planar metallic upper section having a longitudinal axis, the upper section comprising a pair of longitudinal members defining a central open region, each longitudinal member having a lower end, the longitudinal members joined by a top manipulating end having one or more lifting features formed therein configured to accept one or more manipulators, the one or more formed lifting features positioned such that when the modular tool body and a valve connected thereto are lifted by the one or more manipulators, they are configured to allow the modular tool body and valve to be moved over, aligned with, and connected with a working drillpipe or other valve, and configured to prevent the one or more manipulators slipping off; a one-piece, formed, tubular metallic fluid diversion cap removably attached to the upper section and having the same longitudinal axis as the upper and lower sections, the fluid diversion cap comprising an upper tubular end having slots dimensioned to substantially mate with a lower region of the top manipulating end of the upper section, a lower tubular end dimensioned to substantially mate with curved inner surfaces of the upper end of the lower section, and a fluid diversion opening; and a one-piece, formed, tubular metallic lower section removably attached to the upper section having the same longitudinal axis as the upper section, the lower section comprising: a threaded pin end configured to threadedly mate with a threaded box end of the valve; a central longitudinal bore; and an upper end formed to accept the lower ends of the longitudinal members of the upper section and retaining members therefore.
