Slip and Cut Drilling line: Top Drive Maintenance: Download Top Drive System Maintenance From Nabors.com References: A top drive is an essential part of the drilling equipment. It is located on a drilling rig (Check also types of drilling rigs) hoisted on a rig mast or a derrick. 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. It is located at the swivel's place below the traveling block and moves vertically up and down the derrick. [1] Benefits
Top Drive Systems
With over 2,900 top drive systems delivered, we can offer products ranging from the smallest hydraulic power swivel (HPS) units to the largest AC-powered offshore drilling systems with hoisting capacities up to 1,500 tons. We just did a maintenance comparison using the TDS-11SA for 6 months versus one of your competitors. Top-drive drilling has become one of the new technologies of the 1980's. Application of this seemingly old concept is now widespread in most offshore areas of the world. Top-drive drilling may be one of the biggest changes made to the rotary-drilling method since the development of the rotary table. A Top Drive is an essential piece of drilling equipment; it is basically a large motor system which is hoisted in a derrick, mast or drilling rig. Top Drives can be used in a variety of rigs including truck-mounted rigs and offshore rigs. Now that you understand Top Drive basics, let's dive into some more detailed information. The American Petroleum Institute classifies top drives under "Drilling and Production Hoisting Equipment." The largest of the top drives can carry a hoisting capacity of 1500 tons, have upwards of 100,000 foot-pounds of continuous torque, and withstand rotation at the rate of 600 rpm while carrying drilling fluid pressures up to 7,500 psi.
What is Top Drive System?
Overview Tailored systems for onshore and offshore projects We provide a range of AC-driven top drive systems for demanding drilling applications onshore and offshore. All our top drives are supplied with accessories that have been tailored to meet rig requirements. A top drive is comprised of one or more electric or hydraulic motors, which is connected to the drill string via a short section of pipe known as the quill. Suspended from a hook below the. The top-drive is an electrical motor that has the ability to travel vertically up and down and to impart torque to the drill pipe. These drilling rigs began to appear in the late 1990s. Top drives are suspended mechanical drives that provide clockwise torque to the drill string and serve as an alternative to the use of a Kelly drive and rotary table. They consist of one or more electric or hydraulic motors and are connected to the drill string by a short section of pipe that is referred to as the quill. Operation

Top drives reduce risk and increase safety while drilling in several ways. First, a top drive allows the driller to quickly engage and disengage pumps or the rotary while removing or restringing the pipe. Typically, the frequency of pipe getting stuck is significantly reduced when using top drives, thereby resulting in cost savings. The Varco Top Drive drilling system is more than a concept. It is a proven, practical drilling system that has been setting drilling records and producing profits for operators since the early spring of 1982. Time savings have averaged over 25% on the wells drilled with this system.
A top drive is a big motor system which is hoisted in a derrick or mast of a drilling rig. A top drive is a modern rotating system which has been popular for many drilling contractors and oil operators. Top drives can be used on all types of rigs, from truck-mounted rigs to offshore rigs. A top drive allows a drilling rig to drill a deeper section of a drill pipe in one operation, as a rotary table rig can only drill 30 feet / 9.1 metre sections. By contrast, a top drive can drill between 60 to 90 feet / 18-27 metres. This ability to deal with longer sections of drill pipe allows a drilling rig fitted with a top drive to make.

This top drive is the definition of The Global Drilling Machine top drive drilling system. As the original model, the GDM850 was introduced to set new standards for performance and power. We paid close attention to what drilling professionals were looking for in a top drive and engineered the most technologically advanced top drive drilling. Our top drives are specially designed for easy integration with various mast designs and support both directional and horizontal drilling processes while delivering high performance and safety.
