PACKER END RING WITH POLYMER GRIPPING DEVICE |
摘要 |
<p>A packer can include an end ring positioned proximate a seal element on a base pipe, and a gripping device positioned in an annular space between the end ring and the base pipe, the gripping device comprising a polymer composition material. A method of constructing a packer can include positioning an end ring on a base pipe, and then injecting a gripping device into an annular space between the end ring and the base pipe, whereby the gripping device grips the base pipe. Another method of constructing a packer can include positioning a gripping device in an annular space between an end ring and a base pipe, so that the gripping device grips the base pipe, the gripping device comprising a polymer composition material.</p> |
