What is a traveling block in drilling?

What is a traveling block in drilling?

A traveling block is a multi-sheave pulley used to raise or lower the drill string and casings into a well bore. The blocks typically consist of four to six individual sheaves over which the steel cables used to suspend the traveling black are passed.

What is top drive system?

A top drive is a mechanical device on a drilling rig that provides clockwise torque to the drill string to drill a borehole. It is an alternative to the rotary table and kelly drive. The top drive allows the drilling rig to drill the longer section of a stand of drill pipe in one operation.

What is a rotary table on an oil rig?

1. n. [Drilling] The revolving or spinning section of the drillfloor that provides power to turn the drillstring in a clockwise direction (as viewed from above).

What is shale shaker in drilling?

Shale shakers are components of drilling equipment used in many industries, such as coal cleaning, mining, oil and gas drilling. They are the first phase of a solids control system on a drilling rig, and are used to remove large solids (cuttings) from the drilling fluid (“mud”).

How does crown block and Travelling block work together to run in and pull out heavy drill string?

Lifting systems. The fast line runs from the draw works to the first pulley on the crown block. The wireline then runs down to the first pulley on the traveling block, then back up to the second pulley on the crown block, etc. The hook on the traveling block holds the swivel which supports the drill string.

What is TDS 11SA?

The TDS-11SA sets the standard for dependability, performance and quality. Delivering 500 tons of hoisting capacity, 800 horsepower and 37,100 ft-lbs of continuous drilling torque, the effectiveness and established reputation of the top drive is unmatched within the industry.

What is a collar in drilling?

Drill collars are thick-walled tubular pieces machined from solid bars of steel, usually plain carbon steel but sometimes of nonmagnetic nickel-copper alloy or other nonmagnetic premium alloys. The bars of steel are drilled from end to end to provide a passage to pumping drilling fluids through the collars.

What are Shaker screens?

Shaker screens is the exact media contacting drilling cuttings. Drilling fluid with cuttings or harmful solids flow through screen panel, and then under vibration filtering particles out. We know screen cloth, especially the surface layer is thin or extra thin, it’s easy to broken.

What is Desander in oil and gas?

eProcess Wellhead Desander cyclones are pressure drop dependent, where multiphase fluids are directed into the cyclone causing the fluids to spin under a centrifugal force. These strong forces cause the solids and fluids to separate. Gas in particular, disengages and separates quickly.

What are the parts of a derrick?

A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a stiffleg derrick.

What are the main component parts of a rotary drilling rig?

The basic rotary drilling system consists of four groups of components – the prime movers, hoisting equipment, rotating equipment and circulating equipment – that all combine to make rotary drilling possible.
