D and DL Annular Blowout Preventers

Transcription

1 D and DL Annular Blowout Preventers In the unique design of the Cameron DL Annular BOP, closing pressure forces the operating piston and pusher plate upward to displace the solid elastomer donut and force the packer to close inward. As the packer closes, interlocking 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. Other features of the DL BOP include: The Cameron DL BOP is shorter in height than comparable annular preventers. Available in dual configuration in certain sizes. A quick-release top with a one-piece split lock ring permits quick packer change-out with no loose parts involved. The design also provides visual indication of whether the top is locked or unlocked. The DL BOP is designed to simplify field maintenance. Components subject to wear are field-replaceable and the entire operating system may be removed in the field for immediate change-out without removing the BOP from the stack. Twin seals separated by a vented chamber positively isolate the BOP operating system from well bore pressure. High strength polymer bearing rings prevent metal-to-metal contact and reduce wear between all moving parts of the operating systems. All Cameron DL BOPs are manufactured to comply with NACE specification MR for H 2 S service. A shallow gas bleed port is available in some sizes. Packers for DL BOPs have the capacity to strip pipe as well as close and seal on almost any size or shape object that will fit into the well bore. These packers will also close and seal on open hole. Popular sizes of the DL BOP are available with high-performance CAMULAR TM annular packing subassemblies. Special stripper packers are available in some sizes to accommodate 6-5/8" pipe/mandrels. The Cameron DL BOP is available in sizes from 7-1/16 to 21-1/4 and in working pressures from 2000 to 20,000 psi. TC Cooper Cameron, Cameron Division

15 DL Annular BOP Replacement Part Kits For popular size DL BOPs, a BOP replacement parts kit is available to provide all seals, bearings and scrapers required during normal maintenance. Kit parts are shrink-film packed to prevent loss and assure long shelf life and are less expensive than individual parts. All parts in each kit are identified with part numbers and parts list index numbers. As an optional replacement for the standard lip seal design, a D-shaped seal is available for service in annular BOPs that have pitted, corroded or oversized seal grooves. To enhance the performance life of the used annular BOP, this seal design will fill most voids created by excessive wear and tear to the seal groove. Seal kits have been created which include all the operating system seals for the annular BOPs listed below.

17 Annular Stripper Packer Cameron s Stripper Packer is designed to permit stripping of a 6-5/8 drill pipe and tool joint through the Cameron DL Annular. To accomplish the stripping function, the packer metal inserts tips have been cut back to allow the drill pipe to pass through the closed packer without contacting the metal inserts. This special packer is not rated for 10,000 psi service on any size drill pipe because the tops of the anti-extrusion inserts have been cut back. Because this is a special service packing element, it is not tested in accordance with API 16A. Annular BOP Stripper Packer BOP Size Pressure Rating (psi) Stripper Packer 18-3/4" 10,000** **Packer is designed for the 18-3/4" 10,000 DL Annular, but is not rated for 10,000 psi service. Pressure testing of the packing element is limited to 5000 psi on 5" and 6-5/8" drill pipe mandrels. Severe Service Annular Packer Cameron s Severe Service Annular Packing element subassemblies are designed for elevated temperatures (maximum of 250 degrees F.) and up to 35% H2S. The severe service packers/donuts are molded using CAMLAST elastomers. Limited sizes and working pressure are available. Severe Service Annular BOP Packer/Donut Subassembly BOP Size Pressure Rating (psi) Stripper Packer 13-5/8" Higher Temperatures For temperatures greater than 250 O F, and high H 2 S levels, CAMULAR severe service elastomer is recommended. The DL Annular BOP packing element comes only as a complete subassembly, which includes packer and donut. Contact your local Cameron representative for details.
