What is the string?

The bushing chain is a long part of male and female tubes used in the oil field. To create a seal between pipes and soil, the housing is often fastened on the spot to ensure that there is no damage when the oil walk. This pipe chain is used to prevent drilling problems because there may be soil problems if the drill passes from the surface to the target depth in one shot. Most housing chains are made of steel and there are different signs for different land and drilling conditions. Although this string can be made of one pipe, it is rare. Instead, many different pipes are usually used and are divided into long pipes and short pipes - compared to household pipes are still very long. Each of the long pipes has men connectors, short tubes are women and around the male sees.

After the case string is dropped into a well of the oil field, the cement is commonly used to seal the well. There are several sanewater. If the string is not cemented, then there is a chance that it moves during the operation, which increases the chances that its rupture. Another reason is that it is a pressure seal around the pipeline, which can also help protect the integrity of the chain.

The purpose of using the housing chain is to keep the soil for oil fields and the environment. For example, if someone drills down to the target depth without using these pipes, the soil can change seriously or the oil can spill into fresh water. Instead, the drill is lowered by a tube, making it easier to keep the soil safe and ensuring that the oil does not exceed the water or dirt.

Almost all pipes of the case are made of steel, because steel is non -corrosive and can stand on the strength of gushing oil. Different steels are used to create these tubes and these signs may suit different purposes. For example, lighter signs with easier afterThey use and work well for easy drilling conditions, while for heavier drilling conditions, heavier signs may be needed.
