SURFACE WELLHEAD ELECTRICAL CONNECTION AND METHOD OF USE
An economical connection to the electrical conductors extending from a wellhead penetrator is disclosed allowing several forms of connection using a flexible fitting attached to the wellhead enclosing the conductors extending out of the wellhead and allowing the connection to the surface conductors. Because of the flexibility of the braided fitting attached to the tubular connector sleeve, the splice of the electrical conductors can be accomplished quickly and efficiently.
This invention is an electrical connection; more specifically, this device connects electrical conductors coming from a wellhead penetrator to a surface conductor through a flexible braided fitting connected to a tubular connector sleeve, allowing natural aspiration at its distal end, while enclosing one or more splice boots which can be fabricated from polytetrafluoroethylene (PTFE) or cold wrapped connections.
BACKGROUND INFORMATIONElectrical conductors that extend from a wellhead are normally placed into affixed covers designed to avoid entanglement with other portions of the wellhead. In many situations, being able to quickly connect the surface electrical conductors is desired. The present surface wellhead electrical connection allows a rapid connection of electrical conductors extending from a penetrator through a wellhead to surface electrical conductors. The PTFE boots described herein are more fully described in the PCT Application for the Power Cable Splice Sleeve and Method of Installation no. PCT/US2013/048,240 filed 27 Jun. 2013, which is incorporated by reference as if fully copied herein for all purposes.
This application also claims priority back to the Non-Provisional Application No. 61/869,650 filed 23 Aug. 2013.
SUMMARY OF INVENTIONThis surface wellhead connection is comprised of a flexible braided fitting having external threads on both ends for connection on one end to a wellhead and on the other end to a reducer connected to a tubular connector sleeve enclosing a plurality of electrical conductors extending from the wellhead. Surface electrical conductors connected to a surface conduit extend from a blanking cap which is sized or perforated to allow natural aspiration of the interior of the tubular connector sleeve and an insulating boot surrounds and protects each splice of the electrical conductors.
The tubular connector sleeve can be formed from one tubular member or from two telescoping tubular members. When formed from two telescoping members, the tubular sleeve can be connected with screws. The spliced insulated electrical conductors are retained in a boot, which can be formed from polytetrafluoroethylene (PTFE) or polyether ether ketone (PEEK).
The PTFE boot can be fabricated with two or three threaded connections. Alternatively, each insulated electrical conductors could be retained in a cold-shrink boot.
