1.What is a water well casing pipe system?
Water well casing pipe is a device used to control the collapse of the side walls of the water well and ensure the safety of work at the wellhead. It consists of two parts: the casing body and the casing accessories. The water well casing system consists of the casing, cement for burying the casing, the interlayer for fixing the casing, and the casing connector.
2.Main functional features of water well casing
(1) Controlling the collapse of the side walls of the wellboreThe collapse of the side walls of the wellbore is one of the more common problems in water well drilling. At this time, the use of water well casing can effectively control the collapse of the side walls of the wellbore. By fixing the casing, the side walls will not collapse during the drilling process, ensuring the safety and stability of the drilling.
(2) Providing support brackets
The establishment of the casing can utilize the hollow inside to pump cement to achieve a solidification effect. Then, while effectively controlling the wall of the wellbore to prevent collapse, the cement forms a strong bracket, making the overall structure of the wellbore stable and strong, achieving the role of support.
(3) Ensure environmental hygiene
During drilling in a wellbore, a large amount of sludge is often produced. If this sludge is leaked out at will, it will not only pollute the ground environment, but may also affect surrounding crops. By using a casing system, it can be sealed after drilling, and additional devices can be used to completely seal impurities such as sludge, thereby ensuring environmental hygiene.
(4) Achieve the effect of eliminating wellhead collapse
The interlayer around the wellhead can effectively prevent the wellhead from deforming and moving under an external restricted environment. In response to leakage and other problems, a special sealing device is set in the casing system to ensure the safety and stability of the entire wellhead system.
Through the above analysis, it can be said that the advantages of the water well casing system are unquestionable. It can not only control the collapse of the wellbore wall, but also support and seal the wellhead, while ensuring environmental hygiene. Such a device with multiple important functions is an important guarantee for modern water well drilling.
In short, after later improvements, the water well casing system has gradually become one of the important guarantees for water well drilling. In the process of industrial and agricultural production, we must truly do all preventive work to make human living and working environment better and safer.
