What is a conductor pipe?

The wire pipe is a relatively short pipe of large diameter introduced into the ground before drilling holes or oil wells. This part of the pipes, which is also known as the driving pipe, serves to support the initial sedimentary part of the well and prevent a looser surface layer from slipping and defending wellbed. The pipe also serves several other purposes, such as water protection bearing sands and returning from the drill head. In this role, the most commonly used pipe is used in coastal wells, although it is often used for similar reasons to sweat coastal holes. The conductor pipes are usually installed by drilling, mass driving or a combination of these techniques. The collapse of the upper part of the well not only causes lengthy periods, but also represents a significant security risk. To prevent the collapse of this unstable layer, the sedimentary layer is powered by a short guide pipe with a large diameter to support the well during drilling. These tubes are used in the coastal and offshore wells, while pRolls on the mainland are a more common application. In the case of underwater holes, the conductor pipe can also be used as a foundation for a well.

Installation of the conductor pipe also serves several other secondary purposes in addition to the well support. It is used to seal the freshwater zone from the intrusion of drilling and study fluids. Drill slices suspended during drill mud are also removed by means of guide pipes, while the pipeline lends the protection and support of the surface cover, which is another series of external pipes in the well structure. In addition to these advantages, the pipe is also running diving operations ENTS are washing free material under the drilling kit.

In most cases, the wire pipe is installed in one of the three ways. The pipes can be hit by a hole drill with a snail drill and then fastened to a place, or the second method is a ride on a pile that sees a tube inserted into the ground by recurring strokesFrom a heavy pneumatic or diesel hammer known as a pilot driver. The third method is a combination of the previous two procedures and is used where the pile control cannot control the wire pipe to the correct depth. In this case, the pipeline is driven to the point where it refuses to go further, then the hole is pulled by a short distance by drilling and the pipeline is re -introduced until the refusal. This process is repeated until the pipeline reaches the correct depth.
