发明名称 Wellhead for a hydrocarbon-producing wellbore
摘要 A wellhead for a hydrocarbon-producing wellbore includes a wellhead body having an inner cavity, and a production fluid conduit. The production fluid conduit and the wellbore define a production fluid flow path. A stuffing box is positioned within the inner cavity. A leak containment structure within the inner cavity captures any fluid exiting the stuffing box. A fluid pump pumps fluids from the leak containment structure to the production fluid flow path.

主权项 1. A wellhead for a hydrocarbon-producing wellbore, comprising: a wellhead body for mounting on a wellbore, the wellhead body having an inner cavity, and a production fluid conduit, the production fluid conduit and the wellbore defining a production fluid flow path; a stuffing box positioned within the inner cavity; a leak containment structure within the inner cavity to capture any fluid exiting the stuffing box; and an internal flow conduit and a valve both within the wellhead body, wherein the internal flow conduit connects the leak containment structure to a portion of the production fluid conduit within the wellhead body to enable fluid captured by the leak containment structure to be routed from the leak containment structure to the portion of the production fluid conduit within the wellhead body through the internal flow conduit, and the valve is positioned to regulate fluid flow through the internal flow conduit between the leak containment structure and the portion of the production fluid conduit within the wellhead body.
