The invention is directed to breechblock connections to and between oil field equipment and oil field lines for use with oil field equipment associated with oil and gas exploration, drilling, and production. The oil field lines and oil field equipment of the invention include a breechblock connection for quick and easy removal and installation of the oil field lines to oil field equipment and to other oil field lines, and connections between different pieces of oil field equipment. Methods of connecting lines to oil field equipment and connecting one piece of oil field equipment to a second piece of oil field equipment are also disclosed.

Breechblock connectors for use with oil field lines and oil field equipment

The invention is directed to pressure lines for use with equipment associated with drilling and production risers, and in particular, pressure lines having breechblock connections with the equipment and with choke and kill lines for use in connection with different sized blowout preventer stacks ('BOP stacks'). The pressure line systems and choke and kill line systems of the invention include a breechblock connection for quick and easy removal and installation of the pressure lines to riser equipment and the choke and kill lines to BOP stacks. Additionally, the choke and kill lines of the invention may include a coupling system having a BOP connector, or plate assembly, for permitting one set of choke and kill lines to be used on various sized BOP stacks. The plate assembly is in fluid communication with a first choke or kill line connector. Each of the choke and kill lines, or hoses, include a second choke or kill line connector, preferably as part of a line assembly, which is capable of being releaseably secured to the first choke or kill line connector. Therefore, by installing a plate assembly on different sized BOP stacks, one set of choke and kill lines can be used in connection with multiple sized BOP stacks. Methods of replacing BOP stacks and installing and removing choke and kill lines and pressure lines are also disclosed.
