In the aspect of online leak sealing operation need according to the specific leakage situation determine appropriate USES what kind of method to do leakage treatment, such as the leakage of low pressure medium, the solidification method is adopted to do patch processing is very appropriate, sometimes just one method can not be leakage, need to adopt comprehensive governance method to deal with the leakage, to ensure enough good plugging effect.

　　So-called comprehensive governance leakage method, it is a combination of a variety of different plugging method, to at the time of actual online leak sealing homework according to the working condition, processing capacity, field situation, the reasonable combination of the above two or more plugging method, such as: first wedge, adhesive, after finally have mechanical fixation; Welding sealant is used after fixed frame, first, the last method of the mechanical jacking is comprehensive, the plugging method is also in the leakage in many ways, even more than many separate plugging method is more widely applied.

　　So if you need to do online leak sealing, found that single plugging method is not suitable, can not solve the problem of well leakage, can consider to use the above this kind of composite plugging method, through integrated multiple ways to do it with, to ensure that the complete solution of system leaks.
