Tool for connecting and disconnecting well pipe

A well tool for connecting or disconnecting joints in a pipe string which extends downwardly into a well, comprising:

• a spinner for gripping an upper one of two threadedly interconnectible pipes of said string rotating it relative to a lower pipe;
• a torque wrench including upper and lower gripping assemblies for gripping said upper and lower pipes respectively, and means for turning one of said assemblies relative to the other to tighten or release the threaded connection between said pipes;
• a slip assembly for engaging and supporting said lower pipe and including a plurality of slips having outer tapering surfaces engageable with tapering slip bowl structure to support the pipe therein;
• a common suport structure for said spinner, torque wrench and slip assembly to be located at a side of the well;
• means mounting said spinner and torque wrench to said support structure for upward and downward movement relative thereto and for movement generally horizontally between active positions about the pipes and retracted positions at a side of the pipes;
• and
• means mounting said slip assembly to said common support structure for movement between an active position about the lower pipe and a retracted position offset to a side of the pipe and for movement upwardly and downwardly relative to said support structure and relative to said spinner and said torque wrench.
