The conventional rotary rig was the most common rig used during the past century (1900s) and is the drilling rig that you are probably most familiar with from old movies and documentaries. A schematic of a conventional rotary drilling rig is shown in the schematic diagram in Figure 8.03.

In addition, Figure 9.02 shows a more detailed schematic diagram of a rotary table, land rig. Author: Gregory King, Professor of Practice, Petroleum and Natural Gas Engineering, The Pennsylvania State University.

The rotary system on a drilling rig is the system that causes the drill bit rotate at the bottom of wellbore. We have discussed some components of the rotary system when we discussed rotary table and top-drive rigs, but we have not yet discussed the entire system.

A rotary table is a mechanical device on a drilling rig that provides clockwise (as viewed from above) rotational force to the drill string to facilitate the process of drilling a borehole. Rotary speed is the number of times the rotary table makes one full revolution in one minute (rpm).

• The rotary system is used to rotate the drillstring, and therefore the drill bit, on the bottom of the borehole. Generally, rigs can rotate the bit in one of three ways:

Rotary drilling rig is a kind of construction machinery which is used for deep pile foundation hole drilling operation.

This document provides a diagram and descriptions of the key components of an onshore rotary drilling rig. It explains that the rig uses a derrick structure to support equipment for raising and lowering the drill string such as the drawworks, block and tackle, and kelly drive.

This paper presents a control system design methodology for the drill-string rotary drive and draw-works hoist system aimed at mature drilling rig retrofitting.

Figure 1 shows a simple diagram of a rotary rig. Drilling fluids went through major technological evolution, since the first operations performed in the US, using a simple mixture of water...
