Abstract

1,273,483. Blowout preventers. REGAN FORGE & ENG. CO. 6 Aug., 1970 [23 Oct., 1969], No. 38065/70. Heading E1F. A blowout preventer apparatus comprises a radially compressible annular packing mounted in a chamber, and an annular rubber-like packing insert adapted to be positioned within the packing so that when the packing is compressed the insert seals about a tool passed through the chamber. The apparatus shown has an annular packing 33, 37 mounted in a chamber 30, and an insert 46 which has a rigid ring 48 located by shoulder 51 and a rigid ring 47 whose circumferential groove 55 is engaged by latch dog 59 to locate the insert. Packing 33, 37 is compressed by hydraulic fluid in housing 30 to seal insert 46 about tool 17. The passage of a tool joint 18 forces open insert 46 and fluid is forced from chamber 30 into accumulator 75. When the joint has passed through the insert the accumulator forces the fluid back into the chamber to re-seal the insert about the tool. The unit is retrieved by releasing the hydraulic pressure, operating a hydraulic actuator to withdraw dog 59, and lifting the insert with a tool which has dogs extending beneath ring 48.
