Pressure plugging, as a transformation technology, has been widely used in various fields. It can effectively solve the problem of water leakage in pipelines, wellheads and other facilities, and can also be used for the plugging of underground water sources and the prevention and control of geological disasters. The sealing technology with pressure is characterized by high efficiency, energy saving, high technical content and difficulty, and requires training and rich practical experience to master.

The principle of sealing with pressure is to inject a specific sealing material into the pipeline or wellhead, so that it can quickly cure under high pressure environment, forming a solid sealing layer, so as to achieve the closure of the leakage point. This technology can repair existing water leakage problems, and can also prevent future water leakage risks by preventive plugging of the pipeline while it is running. Compared with traditional plugging methods, sealing with pressure has higher reliability and durability, and can effectively extend the service life of pipelines and facilities.

The application range of sealing technology with pressure is very wide, covering many fields such as oil, gas, water and so on. In oil and gas exploration and development, pipeline leakage is a common problem, if not repaired in time, may lead to serious environmental pollution and stability accidents. Through the pressure sealing technology, the pipeline leakage can be repaired quickly and effectively to ensure the smooth operation of production. In hydraulic engineering, the plugging of underground water source is also a key problem, and the plugging technology

One of the characteristics of the pressure sealing technique is its high efficiency. The traditional sealing method requires shutdown and maintenance, which is time-consuming and labor-intensive, while the pressure sealing technology can be repaired when the pipeline is running, without affecting the production process, and greatly improve the work efficiency. In addition, the sealing technology with pressure also has the characteristics of energy saving and stability. It does not require a lot of manpower and material resources, reduces the damage to the environment, and meets the requirements of modern society for sustainable development.

However, pressure plugging technology also has some challenges and difficulties. First, the choice of plugging material is crucial. Different pipeline materials and environmental conditions need to choose different sealing materials, and the performance of the sealing material directly affects the sealing effect. Secondly, the pressure plugging technology requires the operator to have a high technical level and rich experience, once the improper operation may lead to plugging failure, and even cause stability accidents. Therefore, for the promotion and application of pressure plugging technology, it is necessary to strengthen training and supervision to ensure that operators have the necessary skills and knowledge.

In general, as a kind of reconstruction technology, sealing with pressure has high practical value and development prospect. With the continuous development of society and the continuous progress of technology, pressure sealing technology will be applied in more fields, providing more reliable and durable solutions for all walks of life. It is hoped that there will be more research and innovation in the future to further improve the sealing technology with pressure and make greater contributions to the sustainable development of society.
