Annulars Cameron Dl

Cameron annular blowout preventers are available in bore sizes from 7 V16" to 21 %" and in pressure ratings to 20,000 psi.

  • The packer is able to contain full rated working pressure even after long periods of use.
  • Packer replacement is simple and fast. The quick release top, with its one-piece split lock ring, permits quick packer change out with no loose parts involved.
  • The annular is designed to simplify field maintenance. Components subject to wear are replaceable in the field. The entire operating system may be removed in the field for immediate change out with a spare system, while the BOP remains in place on the stack.

1.5.1 Operation of 'DL' Annular

Closing pressure forces the operating piston and pusher plate to close upward. As the packer closes, steel reinforcing inserts rotate inward to form a continuous support ring of steel at the top and bottom of the packer. The inserts remain in contact with each other whether the packer is open, closed on pipe, or closed on open hole.

1.5.2 Cameron 'DL' Packing Unit

The 'DL' packer has the capacity to strip pipe as well as close and seal on almost any size or shape object that will fit into the wellbore. These packers will also close and seal on open hole. The 'DL' packer has an added feature, which allows it to be split for installation while pipe is in the hole. The new Camular annular packers are improved packing elements available for the Cameron 'DL'. Each assembly includes the annular packer and donut and provides a longer service life, excellent synthetic oil base and diesel mud resistance and higher temperature tolerance (up to 180 deg F).
