Stand (drill Pipe)
A stand (of drill pipe) is two or three joints of drill pipe connected and stood in the derrick vertically, usually while tripping pipe. A stand of collars is similar, only made up of collars and a collar head. The collar head is screwed into the collar to allow it to be picked up by the elevators. Stands are emplaced inside of the "board" of the drilling rig. They are usually kept between "fingers". Most boards will allow stands to go ten stands deep and as much as fifty stands wide on land based rigs. The stands are further held in place using ropes in the board which are tied in a shoe knot by the derrickman. Stands are emplaced on the floor of the drilling rig by the chain hand. When stands are being put onto the floor the chainhand is said to be "racking stands". After the bottom of the stand is placed on the floor, the derrickman will unlatch the elevators and pull the stand in either with a rope or with just his arms. When stands are being put back into the hole, the der ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drill Pipe
Drill pipe, is hollow, thin-walled, steel or aluminium alloy piping that is used on drilling rigs. It is hollow to allow drilling fluid to be pumped down the hole through the bit and back up the annulus. It comes in a variety of sizes, strengths, and wall thicknesses, but is typically 27 to 32 feet in length (Range 2). Longer lengths, up to 45 feet, exist (Range 3). Background Drill stems must be designed to transfer drilling torque for combined lengths that often exceed several miles down into the Earth's crust, and also must be able to resist pressure differentials between inside and outside (or vice versa), and have sufficient strength to suspend the total weight of deeper components. For deep wells this requires tempered steel tubes that are expensive, and owners spend considerable efforts to reuse them after finishing a well. A used drill stem is inspected on site, or off location. Ultrasonic testing and modified instruments similar to the spherometer are used at inspection ...

Derrick
A derrick is a lifting device composed at minimum of one guyed mast, as in a gin pole, which may be articulated over a load by adjusting its guys. Most derricks have at least two components, either a guyed mast or self-supporting tower, and a boom hinged at its base to provide articulation, as in a ''stiffleg'' derrick. The most basic type of derrick is controlled by three or four lines connected to the top of the mast, which allow it both to move laterally and cant up and down. To lift a load, a separate line runs up and over the mast with a hook on its free end, as with a crane. Forms of derricks are commonly found aboard ships and at docking facilities. Some large derricks are mounted on dedicated vessels, and known as floating derricks and sheerlegs. The term derrick is also applied to the framework supporting a drilling apparatus in an oil rig. The derrick derives its name from a type of gallows named after Thomas Derrick, an Elizabethan era English executioner. Types ...

Tripping (pipe)
{{unreferenced, date=January 2015 Tripping pipe (or "Making a round trip" or simply "Making a trip") is the physical act of pulling the drill string out of the wellbore and then running it back in. This is done by physically breaking out or disconnecting (when pulling out of the hole) ''every other 2 or 3 joints of drill pipe'' at a time (called a stand) and racking them vertically in the derrick. When feasible the driller will start each successive trip on a different "break" so that after several trips fresh pipe dope will have been applied (when running back in the hole) to every segment of the drill string. The most typical reason for tripping pipe is to replace a worn-out drill bit. Though there are many problems that occur to warrant the tripping of pipe. Downhole tools such as MWD (measurement while drilling), LWD (logging while drilling) or mud motors break down quite often. Another common reason for tripping is to replace damaged drill pipe. It is important to get the ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Drilling Rig (petroleum)
This article lists the main components of a petroleum onshore drilling rig. Offshore drilling rigs have similar elements, but are configured with a number of different drilling systems to suit drilling in the marine environment. The equipment associated with a rig is to some extent dependent on the type of rig but typically includes at least some of the items listed below. {{clear List of items #Mud tank #Shale shakers # Suction line (mud pump) #Mud pump #Motor or power source #hose #Drawworks # Standpipe #Kelly hose # Goose-neck # Traveling block # Drill line #Crown block #Derrick # Racking Board (Sometimes referred to as the Monkey Board) #Stand (of drill pipe) # Setback (floor) #Swivel (On newer rigs this may be replaced by a top drive) #Kelly drive #Rotary table #Drill floor #Bell nipple #Blowout preventer (BOP) Annular type #Blowout preventer (BOP) Pipe ram & blind ram #Drill string #Drill bit #Casing head or Wellhead #Flow line Explanation *Bell nipple (#22) is a sectio ...
