摘要

System and method for forming an annular insulator between a pipe and a boring hole.The present invention relates to apparatus and methods for forming an annular insulator in a boring hole after the installation of the production tubing.The annular sealing device is carried in the production tubing, or inside of her, when she develops inside a boring hole.In combination with the expansion of the tubing, the seal is folded to form an insulator ring.An inflatable element carried by the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing.Reactive chemicals can be taken inside of the pipe and injected in the annular crown to react with each other and with fluid environments to increase volume and harden within a veDhaka annul.A shirt.An elastomeric ring or band carried in the pipe can expand until contact with the wall of the drill hole and can have its radial dimension increased along with the expansion of the pipe isThe sea an insulator ring.
