Pressure plugging technology is an innovative technology, widely used in oil and gas, chemical industry, construction and other fields. With the continuous growth of energy demand and the improvement of environmental protection requirements, pressure sealing technology has been gradually paid attention to because of its high efficiency and economic characteristics. This paper will deeply discuss the application field of pressure sealing technology, analyze its application examples in various industries and future development prospects.

#### 1. Oil and gas industry

1. ** Sealing of oil and gas Wells **

Pressure plugging technology is common in the oil and gas industry and is mainly used to plug oil and gas Wells. In the process of oil field development, oil leakage or gas leakage may occur in the wellbore. The traditional plugging method needs to stop production and reduce the wellhead pressure, but the pressure sealing technology can reduce production loss and environmental pollution while maintaining the wellhead pressure.

2. ** Workover operation **

In workover operation, the application of pressure plugging technology can improve the stability of workover and prevent well fluid leakage effectively. When dealing with downhole faults, the pressure plug can quickly isolate the problem section, carry out effective repair work, and ensure the stability of the wellhead.

3. ** Oil and Gas Storage facilities **

Oil and gas storage facilities will inevitably leak during use, and pressure sealing technology can be used to seal and seal storage tanks, pipelines and other facilities to ensure environmental pollution and economic losses caused by leakage in the storage process.

#### 2. Chemical industry

1. ** Sealing of reactor **

In chemical production, the normal operation of the reactor is very important. Pressure plugging technology can repair equipment in the chemical reaction process without affecting the operation of the entire production line, especially in the high temperature, high pressure environment, the traditional method is often unable to apply, and pressure plugging technology can effectively isolate and plug.

2. ** Pipeline maintenance **

The network of pipelines in chemical plants is complex, and pressure plugging technology can be used to maintain and overhaul pipelines without stopping the entire production process. Through temporary plugging, pipes can be cleaned, inspected and repaired, greatly improving production efficiency.

3. ** Maintenance of storage tank **

Chemical storage tanks may leak during use, and the pressure plugging technology can maintain the internal pressure and quickly repair the storage tank, avoiding economic losses caused by shutdown.

#### 3. Construction industry

** Water table control **

In the process of construction, the control of groundwater level is an important link. The sealing technology with pressure can be used to seal the groundwater, ensure the dryness of the construction site, improve the construction efficiency and reduce the construction risk.

2. ** Reinforcement of foundation engineering **

In foundation engineering, if problems such as foundation settlement or cracking are found, the pressure sealing technology can quickly take measures to strengthen the damaged part and avoid greater hidden dangers.

3. ** Sewage treatment facilities **

More and more attention is paid to health in the construction industry, and pressure sealing technology can be used for the maintenance and repair of sewage treatment facilities to ensure that there is no secondary pollution in the sewage treatment process and improve the overall treatment effect.

#### Mining industry

1. ** mine risk control system **

In mining, safety is the primary concern. Pressure sealing technology can be used in mine risk control to help isolate the spread of harmful gases and provide a working environment for miners.

2. ** Mine water management **

In the process of mining, groundwater management is very important. The pressure sealing technology can regulate and control the groundwater level to avoid mine collapse or stabilization accidents caused by water source problems.

3. Disaster prevention and control of ** mine

The mine may encounter fire, explosion and other disasters in the mining process, and the pressure sealing technology can quickly seal the affected area in an emergency, reduce the threat of disasters to miners, and improve the management level of the mine.

#### 5. In the field of health

1. ** Waste treatment **

In the process of waste treatment, the pressure sealing technology can be used to seal the waste landfill, prevent harmful substances from leaking into the groundwater, and protect the environment.

2. Control of pollution sources **

For some facilities that may cause environmental pollution, such as chemical plants and waste dumps, pressure sealing technology can effectively isolate pollution sources and reduce the impact on the surrounding environment.

3. ** Water conservation **

In water conservation areas, pressure sealing technology can be used to control water flow, prevent pollution sources from affecting the water body, and ensure clean water resources.

#### 6. Future development trends

1. ** Technological innovation **

With the progress of science and technology, the equipment and materials with pressure sealing technology will be constantly updated to improve their reliability. At the same time, the application of automation technology will provide a more efficient solution for sealing with pressure.

2. ** Extended application range **

The application field of sealing technology with pressure will continue to expand, and its value may be reflected in more industries in the future, such as new energy development, transportation and other fields.

3. ** Health and safety **

In the context of the world's increasing requirements for health and security, pressure sealing technology will become an important tool to solve various production and environmental problems, and promote the sustainable development of various industries.
