kelly bushing height price

Because wells are not always drilled vertically, there may be two “depths” for every given point in a wellbore: the measured depth (MD) measured along the path of the borehole, and the true vertical depth (TVD), the absolute vertical distance between the datum and the point in the wellbore. In perfectly vertical wells, the TVD equals the MD; otherwise, the TVD is less than the MD measured from the same datum. Common datums used are ground level (GL), drilling rig floor (DF), rotary table (RT), kelly bushing (KB) and mean sea level (MSL). [1]

Kelly Bushing Height (KB):The height of the drilling floor above the ground level. Many wellbore depth measurements are taken from the Kelly Bushing. The Kelly bushing elevation is calculated by adding the ground level to the Kelly bushing height.

Kelly Bushing Height (KB): The height of the drilling floor above the ground level. Many wellbore depth measurements are taken from the Kelly Bushing. The Kelly bushing elevation is calculated by adding the ground level to the Kelly bushing height.

1. n. [Drilling] An adapter that serves to connect the rotary table to the kelly. The kelly bushing has an inside diameter profile that matches that of the kelly, usually square or hexagonal. It is connected to the rotary table by four large steel pins that fit into mating holes in the rotary table.

A Kelly bushing (some people call “rotary Kelly bushing”) engages a master bushing via four pins and rollers inside a Kelly bushing to allow a Kelly to move up or down freely while it is rotated or in a static mode. This video demonstrates how to make a connection via a Kelly system.

Kelly bushing is that elevated device positioned right on top of the rotary table and used to transmit torque from the rotary table to the kelly. The kelly bushing is designed to be the connection between the rotary table and the kelly.

1. n. [Drilling] An adapter that serves to connect the rotary table to the kelly. The kelly bushing has an inside diameter profile that matches that of the kelly, usually square or hexagonal. It is connected to the rotary table by four large steel pins that fit into mating holes in the rotary table.

The kelly is used to transmit rotary motion from the rotary table or kelly bushing to the drillstring, while allowing the drillstring to be lowered or raised during rotation.

1. adj. [Drilling] Referring to the condition that occurs when the kelly is all the way down, so drilling progress cannot continue. A connection must be made, which has the effect of raising the kelly up by the length of the new joint of drillpipe added, so drilling can resume.

This means that Top Drives can drill about 90 feet before making a connection, whereas with a Kelly System, you will make a connection at about 30 feet deep. Another difference between a Kelly and a Top Drive is that a Top Drive System allows rotation and circulation while back reaming out of a hole.

Kelly drive system is capable to drill with one single drill pipe. On other hand TDS is capable to drill with drill pipe stand. One drill pipe stand is made of three drill pipe joints together.

Kelly bars operate by transferring the torque and crowd force from a rotary drive tool to the drilling tool. Many kelly bars can be applied to any type of piling rig that is available on the market. Kelly bars can be divided into two main types: friction kelly bars and interlocking kelly bars.

The wear bushing is housed in the head or in the spool and is secured by means of two tie down screws to protect it against damage or wear during drilling. It is installed or retrieved with either a simple installation tool or with the HCC combined tool.

Kelly Saver Subs refer to a sub used between the Kelly or top head drive and the drill pipe. It is usually a pin to pin sub that takes the wear abuse to protect the drill pipe and the drive connection. Mills can furnish these subs along with the fluted, hex, or square Kelly Bar drive itself.

A mechanical device for rotating the kelly. The kelly spinner is typically pneumatic. It is a relatively low torque device, useful only for the initial makeup of threaded tool joints. It is not strong enough for proper torque of the tool joint or for rotating the drillstring itself.

This means that Top Drives can drill about 90 feet before making a connection, whereas with a Kelly System, you will make a connection at about 30 feet deep. Another difference between a Kelly and a Top Drive is that a Top Drive System allows rotation and circulation while back reaming out of a hole.

Kelly bars are key components in the execution of boreholes with hydraulic rotary drilling rigs. They transfer the torque of the rotary drive and the crowd pressure of the crowd system concurrently to the drilling tool.

A kelly drive is a type of well drilling device on an oil or gas drilling rig that employs a section of pipe with a polygonal (three-, four-, six-, or eight-sided) or splined outer surface, which passes through the matching polygonal or splined kelly (mating) bushing and rotary table.

A conventional rotary rig or rotary table rig or kelly drive rig is a drilling rig where the rotation of the drill string and bit is applied from a rotary table on the rig floor.

Kelly drive system is capable to drill with one single drill pipe. On other hand TDS is capable to drill with drill pipe stand. One drill pipe stand is made of three drill pipe joints together.

Kelly bars operate by transferring the torque and crowd force from a rotary drive tool to the drilling tool. Many kelly bars can be applied to any type of piling rig that is available on the market. Kelly bars can be divided into two main types: friction kelly bars and interlocking kelly bars.

LEE C. MOORE, Set back capacity 700 klb. Height to rotary beams 24 ft. Drill Floor Height 30 ft.; Complete with: Catwalk, 1 Set of Skidding Gear, Hydraulic jack up unit

A pit in the ground to provide additional height between the rig floor and the well head to accommodate the installation of blowout preventers, ratholes, mouseholes, and so forth. It also collects drainage water and other fluids for disposal.†

A device fitted to the rotary table through which the kelly passes. It is the means by which the torque of the rotary table is transmitted to the kelly and to the drill stem. Also called the drive bushing.†

The derrickman"s working platform. Double board, tribble board, fourable board; a monkey board located at a height in the derrick or mast equal to two, three, or four lengths of pipe respectively.†

A hole in the rig floor 30 to 35 feet deep, lined with casing that projects above the floor. The kelly is placed in the rathole when hoisting operations are in progress.†

The hose on a rotary drilling rig that conducts the drilling fluid from the mud pump and standpipe to the swivel and kelly; also called the mud hose or the kelly hose.†

The principal component of a rotary, or rotary machine, used to turn the drill stem and support the drilling assembly. It has a beveled gear arrangement to create the rotational motion and an opening into which bushings are fitted to drive and support the drilling assembly.

Wedge-shaped pieces of metal with teeth or other gripping elements that are used to prevent pipe from slipping down into the hole or to hold pipe in place. Rotary slips fit around the drill pipe and wedge against the master bushing to support the pipe. Power slips are pneumatically or hydraulically actuated devices that allow the crew to dispense with the manual handling of slips when making a connection. Packers and other down hole equipment are secured in position by slips that engage the pipe by action directed at the surface.†

The top drive rotates the drill string end bit without the use of a kelly and rotary table. The top drive is operated from a control console on the rig floor.†

The NOV CUL & CB Casing Bushings are inserted directly into the rotary table and insure that the casing being run is perfectly aligned with the center of the hole. Model CU is a solid bushing and model CB is a split bushing. All of the bushings accept bowls of different sizes to accommodate a wide range of casing. Using CMS-XL or CP-S slips, since these bushings fit into the rotary table, the casing string can be easily rotated during cementing operations.

The swivel allows the kelly to rotate while suspended from the travelling block. Importantly, it allows drilling fluid to flow from the stationary standpipe to the rotating drill string.

This blowout preventer consists of rubber “wedges” that can be extruded into the wellbore by hydraulic pistons. These wedges can create a powerful seal around drill-string pipes as well as irregularly shaped pipes like kellys. Importantly, the pipe can be moved up and down while the preventer is engaged. Annular BOPs are not as effective at closing an open hole as the other types of BOPs.

A high pressure, flexible pipe with an interior diameter of 3-5 inches that carries drilling mud from the standpipe to the kelly or topdrive. The pipe is longer than the distance between these parts in order to accommodate the up-down movement of the kelly or topdrive.

The trip tank is a separate mud storage tank that is used during tripping operations. Fluid from the trip tank is continually circulated through the well during tripping. Pumps associated with the tank ensure that the total height of the mud column in the hole remains constant during tripping operations. This is important for preventing blowouts.

Instead of rotating the drill string with a kelly and rotary table, top drive systems use an electrically powered drive shaft that screws directly into the top of the drill string (kind of like an electric screwdriver or drill). As drilling progresses, the top drive system is lowered deeper into the hole.

A system for providing rotation to a drill string. A non-circular pipe known as a kelly is rotated by an adapter called a kelly bushing, which is in turn rotated by the master bushing and rotary table. The square or hexagonal cross section of the pipe allows it to be rotated while sliding up and down. This allows powered rotation and drilling to occur simultaneously.

The powered mechanism that provides rotational force to the kelly. It is a round table set into the floor of the rig containing a master bushing, which in turn contains the kelly bushing.

The master bushing sits right inside the rotary table. It often contains a bowl shaped depression that allows drillers to insert wedges, which hold up the drill string while it is unscrewed from the kelly. It is also designed to engage the kelly bushing, which is placed inside.

The kelly bushing is essentially an adapter that fits inside the master bushing and transmits rotation to the kelly, which will likely vary in size as drilling progresses and the diameter of the hole decreases.

A rectangular or hexagonal pipe that is screwed into the top of the drill string and transmits the rotation of the rotary table and kelly bushing to the string.

In a kelly drive system, the swivel allows drilling fluid to pass from the static standpipe into the rotating kelly. In a topdrive system, it does essentially the same thing at the top of the drill string.

A high pressure, flexible pipe with an interior diameter of 3-5 inches that carries drilling mud from the standpipe to the kelly or topdrive. The pipe is longer than the distance between these parts in order to accommodate the up-down movement of the kelly or topdrive.

The substructure supports the entire load of the drilling rig. Depending on surface conditions, it may be installed directly on the ground or it may be installed on a custom made foundation. Substructures are rated by maximum load and height (certain blowout preventer stacks may not fit under some substructures). Substructures for onshore drilling are designed to be easily moved, set up, and taken down.

Commonly referred to as the derrick man, a derrick worker cannot be afraid of heights. This position requires working high above the floor, and is used during regular operations to help when the pipe is being pulled or run. In many of the modern rigs, a rack will vertically hold various sections of drill pipe along the side of the derrick. Each is then added to the drilling string as the bit makes it way deeper and deeper into the ground.

As the crew drills the well, the distances are calculated starting from the top of kelly bushing (refers to the sliding bushing located on the drilling rig floor on top of the rotary table that permits the drill kelly  to go down through it when the pipe is turning and the hole is drilled.

Once the casing pipe is permanently cemented into the hole (or set) and either the braiden head or wellhead installed, the measurements from the top of the wellhead to the top of the kelly bushing are calculated and subtracted from all drilling records. This allows precise well records for once the drilling rig is no longer there.
