Top Drives for Sale and Their Application in Oil and Gas Industry

Information may not be reliable

The mechanical device used on a drilling rig is known as a top drive, and it delivers clockwise torque to a drill string to create a borehole. Top drives are alternatives to kelly and rotary table drives in a sense that they are found at the area where the swivel is, beneath the traveling block. However, they move vertically upward and down a derrick. Top drive drilling makes it possible to drill a longer section of the drill pipe’s stand in a single operation. Rotary table type rigs can only drill around 30 feet sections of the drill pipe, while a high-end top drive, like the TDS 11 top drive can drill 60 to 90 feet stands, depending on the size of the drilling rig.

Drilling rigs can become more productive with longer sections of a drill pipe because up to 90 feet can be drilled at a time. This way, you can reduce the need for more connections to add another drill pipe that is 30 feet long. Top drives for sale are made with systems that can help you save time and accomplish more quickly than when you use a kelly drive. With conventional drilling methods, the whole string needs to be taken out of a well bore before another is added. With top drives, only the draw works can pick up the new stand from the rack to create two joints. This way, quicker and fewer connections minimizes the risk of the string getting stuck due to annulus clogging in the absence of drilling fluid.

There are different kinds of top drives for sale and they are typically classified according to the SWL (safe working load) of the equipment, as well as the type and size of motor they have to rotate a drill pipe. For heavy-duty and offshore use, 1,000 short ton top drive drilling equipment is ideal, while a 500 short ton device will do for a small land rig. You should be able to purchase top drives with different sizes of hydraulic motors and with an AC or DC electric motor.

TDS 11 top drive is designed for portable and permanent drilling rigs. It can swivel to generate power of at least 1,000 horsepower to turn the shaft, and it can be suspended from a rig’s derrick without problems. This way, it is considered among the most efficient top drives in the drilling industry.
