Pipe make/break apparatus with gripping jaws and adjustable pipe spinner with oiling system

A pipe make/break apparatus, comprising:

• top, middle and bottom jaws;
• with the apparatus in a make operation, the middle and either the top or bottom jaw are operatively positioned on opposite sides of a joint of a drill pipe;
• with the apparatus in a break operation, the middle jaw and either the top or bottom jaw are operatively positioned on opposite sides of a joint of a drill pipe;
• and
• a grip hold actuator which when in an actuated position causes at least one of the bottom and middle wrenches to be held on the pipe between wrench torquing cycles during the make operation.

A pipe make/break apparatus, comprising:

• top, middle and bottom wrenches;
• with the apparatus in a break position, the middle and bottom wrenches are operatively positioned on opposite sides of a pipe joint of a drill pipe;
• with the apparatus in a make position, the top and middle wrenches are operatively positioned on opposite sides of a pipe joint;
• and
• a grip-hold actuator which when actuated and with the apparatus in the make position causes at least one of the middle and top wrenches to be held on the drill pipe between wrench torquing cycles during a make operation;
• and
• the actuator when deactuated at an end of the make operation causes the at least one of the middle and top wrenches to be released from the drill pipe.

A method of making a drill pipe joint having a top connection and a bottom connection, comprising:

• providing a pipe make apparatus having top, middle and bottom wrenches;
• gripping the bottom connection with the middle wrench in a gripping position;
• gripping the top connection with the top wrench;
• turning the top connection using the top wrench through a plurality of torquing extension cycles, and
• maintaining the middle wrench in the gripping position continuously throughout the plurality of torquing extension cycles.

A pipe spinner assembly, comprising:

• a chain for engaging a pipe section and rotating it in making or breaking operations;
• a spinner motor for operatively running the chain on the pipe section;
• and
• a nozzle for spraying by pressure from the spinner motor, when the spinner motor is running, lubricating oil on the running chain.

A pipe spinner assembly, comprising:

• first and second pivotally mounted casings;
• a first sprocket on the first casing;
• a second sprocket on the second casing;
• a continuous chain passing around the first and second sprockets for rotating a pipe in an operative position relative to the casings;
• a first guide window mounted to at least one of the casings through which the chain passes to reduce bunching of the chain relative on the first sprocket;
• and
• a second guide window mounted to at least one of the casings through which the chain passes to reduce bunching of the chain relative on the second sprocket.

A pipe make or break apparatus, comprising:

• a frame;
• a first wrench connected to the frame and grippable on a lower pipe section;
• a second wrench connected to the frame and grippable on an upper pipe section;
• a torquing cylinder operatively connected between the first or second wrench and the frame;
• with the first and second wrenches gripped on their respective pipe section and the torquing cylinder actuated, the upper pipe section is caused to turn relative to the lower pipe section in a drill pipe make or break operation;
• and
• an emergency stop actuator which when actuated blocks fluid flow to and from the rod and piston side ports of the torquing cylinder thereby automatically protectively locking the cylinder in its position.
