AI Technical Summary

Benefits of technology

"The present invention provides quick connect assemblies for quickly and releasably connecting drilling equipment to a well casing. These assemblies allow for the quick and easy connection of various well related equipment such as blowout preventers. The quick connector fittings have an annular lip that is seated on the casing and a flange that provides an interface for attaching well related equipment. The fittings can be oriented to any position over the casing mouth prior to being quickly and releasably connected to the casing. The technical effects of this invention include quick and easy connection of drilling equipment to the well casing, improved efficiency in drilling operations, and reduced risk of damage to equipment."

Problems solved by technology

Once such a drilling flange is mounted on a casing, it is difficult to remove.
This can be expensive.
Another problem with these flanges is that their orientation with respect to the casing cannot be accurately predetermined.
This shortcoming poses a problem in situations where the equipment to be attached requires a specific orientation relative to the casing.

Embodiment Construction

[0029]This invention relates to quick connect assemblies which include a quick connector fitting (also referred to herein as a “quick connector”) that can be mounted quickly on a well casing providing an interface for the mounting of well related equipment such as blow out preventors (“BOP”). The quick connector fittings may be used and re-used on many different casings.

[0030]In a first embodiment, the quick connect assembly comprises a quick connector fitting 10 and a male receiver 12. The quick connector fitting 10 releasably connects to the male receiver 12 which is coupled to a well casing 14 (FIGS. 1A and 1B). The casings typically have a diameter of 13-⅜ inches. The male receiver is typically connected to the casing using a coupling 16. The coupling is an internally threaded cylindrical member. One end of the coupling is threaded to the external casing threads. The male receiver is then torqued to inner threads on the coupling other end.

[0031]The male receiver is typically a t...

Abstract

A quick connector fitting assembly is provided which includes a fitting which releasably connects to a well casing for providing an interface for the attachment of various types of well related equipment. The quick connector fitting connects using fasteners to a lip or groove formed on the casing. The fasteners can easily connect or disconnect from the groove or lip facilitating the quick connection and disconnection of the fitting from the casing.
