Introduction To A Drilling Rig

A drilling rig mainly is composed of crown molding, travel block, hook, Derrick, swivel, Kelly, draw works, rotary table, blowout preventer, piece, drill collar, drill string, centrifuge, surface casing, mud ditch, mud pit, pulsation dampener, mud pump, and engine.

1) Bit

In the last analysis, the piece is the only portion of the drilling rig equipment which actually makes a hole. This isn’t to imply that the bit can make hole nevertheless, the piece is the most crucial item of a drilling operation.

To choose somewhat, some information has to be known about the nature of the stones to be drilled. This information always contains a factor of thickness in the earth because overall rock hardness (and occasionally abrasives) increases with hole depth. After choosing the little size needed, the best sorts of bits could be determined based on the stone formation anticipated.

2) Drill Stem

Drill stem includes three key elements: drill collars, drill pipe, and Kelly. Listed below are the main functions of the drill stem:

① Drill stem lowers the piece into the hole and withdraws it;

② Section of the drill stem sets weigh on the piece so that the piece can permeate the formations more efficiently;

③ Drill stem exerts a turning or rotating, activity to the piece.

④ Drill stem conducts the drilling fluid under pressure from the surface to the piece.

3) Blocks and Wire Line

The traveling block, crown block, and cable line would be the three elements whose function is to join the encouraging derrick or mast with the load of pipe to be lowered into or withdraw from the pit.

As is true of nearly every component of several rotary rigs, the cubes, and wire-line assembly should have great strength to have the ability to bear heavy loads.
