Abstract

A flowmeter includes an inlet for receiving a wellbore fluid therein, an outlet for discharging the wellbore fluid and a stationary interior wall extending between the inlet and the outlet. A plurality of movable walls within the stationary interior wall defines a flow path therethrough. Each movable wall defines a threaded section on a first lateral end and rotatably supports an adjustment beam on a second lateral end. The adjustment beams include threads engaged with the threaded section of an adjacent movable wall. An actuator is operably coupled to an adjustment beam to rotate the adjustment beam and thereby drive the second lateral sides of the movable walls along the threaded sections of adjacent movable walls and adjust a diameter of the flow path. A sensor is operable to detect a parameter indicative of the pressures of the wellbore fluid from which a flowrate of the wellbore fluid may be determined.

Dependent claims

A wellbore system, comprising:

a wellbore conduit fluidly coupled to a wellbore to receive a wellbore fluid therein;
an adjustable flowmeter arranged within the wellbore conduit and including:
a flowmeter inlet for receiving the wellbore fluid from the wellbore conduit;
a flowmeter outlet for discharging the wellbore fluid;
and
a stationary interior wall extending between the flowmeter inlet and the flowmeter outlet;
and
an adjustment mechanism provided within the adjustable flowmeter and including:
a plurality of movable walls disposed within the stationary interior wall and defining a flow path therethrough, each movable wall defining a threaded section on a first lateral end thereof;
a plurality of adjustment beams, each adjustment beam being rotatably supported on a second lateral end of a respective one of the movable walls, and each adjustment beam including threads thereon engaged with the threaded section of an adjacent one of the plurality of movable walls;
an actuator operably coupled to at least one adjustment beam of the plurality of adjustment beams to rotate the at least one adjustment beam and thereby drive the second lateral end of each movable wall along the threaded section of an adjacent movable wall to thereby adjust a diameter of the flow path.
