Abstract
The present disclosure provides a dis-connectable wellhead hanger arrangement permitting a pig tail set of a electrical conductors to be inserted within the wellhead hanger arrangement which seals against the wellhead hanger upon separation of an electrical power cable. If the power cable separates from the production tubing for any reason, the compressively fit plugs disconnect the power cable from the pathway leaving the electrical mandrel sealed within the wellhead hanger, thereby sealing the wellhead hanger from loss of fluid after separation.
Claims17
A well bore connector comprising:
- a wellhead hanger adapted to seat in a well head;
- an electrical connector mandrel inserted in the wellhead hanger;
- a female pin connection socket inserted in the electrical connector mandrel;
- a mini-mandrel inserted in the wellhead hanger having one or more electrical conductors sealed within the mandrel and extending from the mandrel
- a male pin attached to a stripped end of an electrical conductor extending from the min-mandrel inserted into the female pin socket;
- a dis-connectable connection between the female pin socket and male pin, within the wellhead hanger, permitting separation between the electrical connector mandrel from the mini-mandrel, sealing the well bore to prevent fluids from release upon disconnection.
A well bore connector assembly connected in a wellhead hanger comprising:
- an electrical connector mandrel inserted in the well-bore connector assembly;
- a female pin connection socket inserted in the electrical connector mandrel;
- a mini-mandrel inserted in the well-bore connector assembly having one or more electrical conductors sealed within the mandrel and extending from the mandrel;
- a male pin attached to a stripped end of an electrical conductor extending from the min-mandrel inserted into the female pin socket;
- a dis-connectable connection between the female pin socket and male pin, within the well-bore connector assembly permitting separation between the electrical connector mandrel from the mini-mandrel, sealing the well bore and the well-bore connector assembly to prevent fluids from release upon disconnection.
A method for installing a dis-connectable electrical connection for use in a wellhead hanger comprising the steps of:
- connecting a female pin connector socket to a stripped end of a upper pig tail conductor;
- inserting the female pin connector socket into an electrical connector mandrel until an upper end of the female pin socket seats against an internal shoulder within the electrical connector mandrel;
- connecting a male pin connector socket to a stripped end of a lower electrical conductor;
- and,
- inserting the male pin connector through a snap ring for insertion in the electrical conductor mandrel until the male pin engages a plurality of contact bands within the female socket end and the snap ring engages in a channel formed within an interior surface of the electrical connector mandrel.
