Drilling rig pdf
Drilling derricks and Rig Masts consist of a steel framework with a square or rectangular cross-section. Their purpose is to support the hoisting equipment and rack the tubulars while tripping pipe. The number of joints in a stand (single-double-triple) that the rig can pull is dependent on the height of the derrick. . The Drawworks is one of the most important components of the drilling rig (types of drilling rigs). The unit supplies the hoisting power, the. . The Crown Blockas a drilling rig component is a fixed set of pulleys (called sheaves) located at the top of the derrick or mast, where the drilling line is threaded. The companion blocks to these pulleys are the traveling blocks. By using two sets of blocks in this fashion,. . The Traveling Blockis a set of sheaves (pulleys) that move up and down in the derrick. The drilling line is threaded (reeved) over the. . Attached to the bottom of the traveling blocks, the hook is required to hang the swivel and rig kelly(for drilling) and the elevator bales (for tripping pipe and casing).

What is the purpose of a drilling rig?
The purpose of a drilling rig is only to drill a hole in the ground. Although the rig is big, the hole it drills is relatively small. The purpose of the drill hole is to tap an oil or gas reservoir often thousands of feet or hundreds of metres below the surface of the earth.
How does a drill rig work?
A drive train which consists of gears or hydraulic pumps is used to convert the power supply to speed and torque for hoisting and rotating the drilling equipment. Most units have a transmission which allows 4 to 8 speeds for hoisting and drilling. In general, the hoisting capacity of the drill rig governs the depth of the borehole.
What are the basic parameters of a drilling rig?
The basic parameters of the drilling rig put forward the conditions about the torque and power of the rotary table, the lifting weight, and control of the hook and the permissible pump pressure and power of the mud pump.
What are the different types of drill rigs?
Drill rigs are designed to perform a certain type of operation. Rotary, churn, and percussion drill rigs are the most common, although a number of other types of rigs have been designed and developed to perform site-specific tasks, such as drilling shot holes in quarries.
What is a rotary drill rig?
Rigs equipped for reverse circulation must have a large rotary table opening that will allow the passage of 10- to 15-cm- (4- to 6-in.-) diam flange-connected drill pipe. A number of other types of rotary drill rigs are available, depending on the requirements of the drilling operations.
What are the requirements for a drilling rig?
These rigs must provide stability on the water during drilling operations; with the exception of fixed platforms, must be portable to allow transport between offshore locations; must have sufficient power to hoist drill pipe and casing to depth; and must provide the maximum amount of available power to circulate drilling fluid.
