What is the Kelly driver?

Well drilling includes the use of equipment to enforce and often remove the Earth's layers to reach the desired substance such as natural gas, oil or water. The general drilling process has not changed much over the years; However, the equipment used for drilling and technological progress has progressed significantly from the originally used wooden structures. The Kelly driver is a piece of pipe -shaped equipment that is used for modern drilling. It is a hexagonal piece of steel pipe located at the top of the drill between the rotary and the drill pipes. The drill chain is a hollow tube that transmits drilling fluid to and from drill bit.

to understand how the driver Kelly is used in well drilling, it is necessary to understand how the drilling process works. Drilling of the well requires a drill, a large piece of motorized device, which is located at the point where drilling occurs. Derrick is an attent to the set to lift the pipes in and out of the well. The crown is a cluster of large flaps and cables that are mounted on itThe river part of the derick to increase and reduce the blocks that hold the drill pipe. The rotary table on the base of the set allows the drill to be rotated so that the holes can be drilled.

Kelly driver rotates a steel piece that hangs down from a swivel table that is connected to the upper joint of the drill. The swivel is the piece used to support the drilling tube. It allows the drilling itself to remain stationary when a rotating table spins around it. The Kelly driver is attached to a piece of drill pipe and as the driver turns, the drill tube enters the ground until the desired depth reaches.

Kelly driver can be either four or six-sided and fits into a slot where a rotary table turns. It is the most strongly weighed-down part of the drilling chain. The Kelly driver's weight is caused by the fact that it is made of chrome and steel treated with a heat treated high degree to form force to be able to boreat the ground.
