We are proud to offer next generation top drive systems, responsive service, parts sourcing and field support. A top drive is an important part of oil well drilling. O    The improved efficiencies coming from a top-drive is that an entire 90-foot stand (or triple) of drill pipe can be connected to the drill string rather than a single 30-foot joint. Top Drive Drilling System 4S Nov. Instead of freeing the slips, the hoist appears to have lifted the entire section of the rig floor covering the rotary table, along with the two roughnecks. • The automatic, driller operated … Improved energy-storage capacity is a key benefit to choosing a hydraulic top drive. of 4. The TDS-4S is NOV’s prime large bore DC top drive. • The pipe handling features use hydraulic arms to move drill pipe and drill collars to and from the V-door and monkey board, thereby reducing strenuous work and increasing pipe handling safety. L    This courseware module is part of Penn State's College of Earth and Mineral Sciences' OER Initiative. Rotation unit : 4.5H.P Rotation unit ; Feed unit. Drillmec HTD series top drives can be fitted to almost any rig in order to increase the performance and help in operations such as directional or horizontal drilling. W    The drillpipe is rotated in stands by a DC electric or hydraulic motor, and the motor with pipe handler travels up and down the derrick on guide rails. The advantages of a top-drive rig are that longer sections of drill pipe can be (1) connected to the drill string when the rig crew is drilling ahead, (2) connected to the drill string when tripping into the hole, or (3) unconnected from the drill string when tripping out of the hole. Throughout the video, you can see these components of the rig used in action. Top-drive drilling may be one of the biggest changes made to the rotary-drilling method since the development of the rotary table. In the screen capture shown in Figure 8.07, we see many of the components discussed in this lesson: the kelly, kelly bushing, rotary table, mousehole, and rat hole. These long horizontal wells are one of the technology enhancements that has resulted in the “shale boom” in the U.S. domestic oil and gas industry in formations such as the low permeability Marcellus Shale in western Pennsylvania, Ohio, and West Virginia. 1. n. [Drilling] A device that turns the drillstring. I would recommend that you go to the website and use the links to get a description of each component of the rig. Yes, I am interested!
