But those who have a certain understanding of online leak sealing operation people should know that the specific methods of this kind of assignment is very much, once the methods are not appropriate, not only can't ensure that solve the problem of well leakage, well plugging operation, and may cause safety accident in the job. So for this type of job chosen appropriate plugging method is very important, such as for plugging effect that is commonly used in solidification method, everyone to the specific process steps and scope of application are fully understand, used carefully confirm the method is appropriate in their own polymer-capsule is adopted.

　　Freezing method, used for the online leak sealing is the use of pressure into the certain substances or medium in the pipeline itself, from leak leakage, meets the air, or some material can be solidified and a method of blocking leakage. Some of the heat medium leakage after solid carbide crystals or can have the effect of plugging, belong to the category of freezing method.

　　Want to remind everyone's attention, solidification method is suitable for low voltage medium leakage, so if it is need to do the online leak sealing, high pressure system is not suitable for using this method, is only suitable for low voltage medium leakage using this method. If you can when using the method of solidification plugging, make appropriate collection medium leakage seal cavity, can obtain plugging effect will be better.
