Abstract

A unitary wellhead flow block lubricator assembly includes a unitary body and flow passageways that extend through the unitary body. Various openings on the exterior of the unitary body allow flow control devices to be mounted in the flow passageways to control the flow of fluid though the flow passageways. One or more of the control devices could be mountable in two or more orientations that alter the way in which the flow control device controls flow through one or more passageways in the unitary body. One or more choke mechanisms may also be mounted on the unitary body. The choke mechanisms may allow an operator to selectively adjust a flow of fluid through one or more of the passageways in the unitary body.

Claims20

Dependent claims

A wellhead flow block lubricator, comprising:

a body configured to be attached to an outflow pipe or a master valve of a wellhead;
a central passageway that extends though the body from a bottom of the body to an upper portion of the body, wherein the central passageway is configured to receive a plunger traveling through the outflow pipe or master valve of the wellhead;
a first outflow passageway that extends through the body from the central passageway to a first lower opening provided on a lower portion of a first side of the body;
an upper passageway that is connected to and that extends away from the central passageway through an upper portion of the body;
a return passageway that extends through the body from the upper passageway to the first outflow passageway;
and
an upper opening provided on an upper portion of the first side of the body, wherein the upper opening extends into at least the return passageway.
