As further improvement of the utility model, described glue core is combined to form by the left glue core being arranged symmetrically with and right glue core
Split type glue core.
The utility model is for realizing closing well head during formation testing, workover treatment.Before lower oil tube, first by glue core
It is arranged in wellhead blowout preventor upper surface, and is fixed by gland, bolt on, the installation of self-packer can be completed.Carrying
In lower Tubing During Running, because the minimum diameter of glue core is less than the external diameter of oil pipe, has resilient glue core and tightly encase oil pipe, reach anti-
Only well head junk occurs, scrapes off oil-pipe external wall crude oil；Gland simultaneously works as on protection preventer during lower oil tube simultaneously
The effect of plane, is not required to another installation in plane on preventer and protects steel plate.
The utility model can effectively solve existing little self-styled problem, can play protection preventer upper flange effect simultaneously,
And by changing glue core, it is achieved positive sand washing, brill milling construction operation wellhead sealing function.Be by former little self-styled, shoulder guard,
Sand washing is integrated from inside back cover instrument, and reaches light and handy, practical, simplifies original troublesome operation, it is achieved Fast Installation purpose, significantly
Mitigate the labour intensity of site operation personnel.
When the positive sand washing of needs, brill milling, it is necessary to use integrally-built glue core, during installation, first pass through oil pipe lower end and lead
Enter monoblock type glue core, under enter in preventer, glue core sits in preventer Flange Plane, then and fixed by gland, bolt on,
Wellhead sealing can be realized.
Rise, lower oil pipe when, it is possible to use integrally-built glue core, it would however also be possible to employ have left glue core and the involutory shape of right glue core
The split type glue core becoming.
