1. n. [Drilling] Large-capacity, self-locking wrenches used to grip drillstring components and apply torque. As with opposing pipe wrenches for a plumber, the tongs must be used in opposing pairs.
Keeping this in consideration, how casing is run in the hole?
Casing is run from the rig floor, connected one joint at a time by casing elevators on the traveling block and stabbed into the previous casing string that has been inserted into the well. Hanging above the drill floor, casing tongs screw each casing joint to the casing string.
Thereof, what are drill pipe elevators?
Elevators, as developed for the drilling industry, are a hinged device with handles that are used to wrap around the tool joint of drill pipe, casing or lift nipples (for collars) to facilitate the lifting or lowering of them singly or of the drill string as a whole.
What are power tongs used for?
Power tongs are essentially large pneumatically or hydraulically operated rig tongs used for turning when making up or breaking out drill pipe, casing, tubing, or other pipe.
What are slips used for in drilling?
Slips is a device used to grip and hold the upper part of a drill string to the drill floor on an oil rig. The slips are constructed as a collection of metal wedges, hinged together to form a circular shape around the drill pipe. On the inside surface, the slips normally has replaceable steel teeth that grips the pipe.
What are Tong dies made of?
Dies are pieces of serrated steel installed in the tongs that grip the tool joint of drill pipe when the tongs are latched onto the pipe. Tong dies are made of alloy steel, and their hardened surfaces resist wear. The inner ductile core minimizes the shock of impact and torque.
What is a kelly rig?
A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table.
What is a rotary slip?
Rotary Slips consist of segments containing inserts that fit around the drill pipe and grip so the pipe does not move down hole. The Rotary Slip is designed to sit inside an insert bowl in the rotary table and apply even pressure around the joint of drill pipe.
What is a tong die?
While running in or pulling out tubulars at oil rigs the joints (tool joints) are tightened or loosened with the help of manual tongs or power tongs. Dies are the principal element in the Manual Tongs and Power Tongs which carry out the job of gripping the tool joints, before torque application.
What is BHA oil and gas?
The Bottom Hole Assembly (BHA) is a key component of the drilling system, consisting of various components and tools (including the drill bit itself) which operate at the bottom of the wellbore and physically drill the rock.
What is kelly bushing in drilling rig?
1. n. [Drilling] An adapter that serves to connect the rotary table to the kelly. The kelly bushing has an inside diameter profile that matches that of the kelly, usually square or hexagonal. It is connected to the rotary table by four large steel pins that fit into mating holes in the rotary table.
What is the most common injury on a rig site ?*?
Injuries in this industry vary dramatically, from injured hips caused by falls to severe burns from explosions. However, the most common injury was amputation, primarily caused by fingers getting caught in machinery. Fractures were the second most common injury. Legs were the body part most commonly fractured.
