Description
Technical Field

Background
After the pressure pipe network is put into use, due to the severe external environment and the limitation of conditions such as heavy use, light maintenance, capital, site and the like in management in the use process, the pipeline updating speed is far behind the pipeline corrosion and aging speed. Particularly, most pipelines have the problems of local aging and serious corrosion when oil field development enters the middle and later stages nowadays. If the pipe network is heavily corroded and aged without further treatment, leakage can occur.
The existing methods for solving the aging and leakage of pipelines are mostly as follows:
(1) The pipelines are stopped and replaced, but part of pipelines cannot be stopped and transported due to the limited conditions, because the production interruption and the equipment damage are caused by the pipeline stopping and the transportation, and the serious economic loss is caused.
(2) The protection pipe needs to be ignited, the ignition not only has great potential safety hazard to the oil pipeline, but also the pipeline body at the welding part is damaged and is easy to corrode, and once leakage occurs again, great difficulty is brought to plugging; moreover, if the aging and the leakage are caused by three-way connection of pipelines, valve banks and other parts, the protection pipe cannot be opened.
(3) The leakage is blocked under pressure without fire, and although the potential safety hazards of large-area well shut-down and fire operation are avoided, the leakage is a temporary emergency measure, and the phenomenon of secondary leakage is very easy to occur.
Once the pipe network leaks, the method poses great threat to production safety, causes serious environmental pollution, reduces production efficiency and causes immeasurable economic loss.
