Abstract
A technique facilitates flow monitoring in a well. A well component is designed for engagement with a well string deployed downhole into a wellbore. The well component has an internal flow passage through which well fluid is flowed. A sensor structure is mounted in the well component along the internal flow passage and comprises at least one sensor designed to sense a parameter related to fluid flow. The sensor structure is movable between a non-intrusive flow position with respect to the internal flow passage and a measurement position within the internal flow passage for measurement of the desired parameter.
Claims24
A system for monitoring flow, comprising:
- a well string having:
- a gauge mandrel with an eccentric portion;
- and a lattice sensor structure pivotably mounted in the eccentric portion, the lattice sensor structure comprising at least one sensor to obtain flow related measurements, wherein the lattice sensor structure is selectively pivotable into and out of a fluid flow through the well string.
A method of monitoring flow in a wellbore, comprising:
- pivotably mounting a flow monitoring sensor structure within a gauge mandrel having a production fluid flow passage extending longitudinally through the gauge mandrel;
- delivering the gauge mandrel downhole into a wellbore with the flow monitoring sensor structure located in a non-intrusive position with respect to the production fluid flow passage;
- and
- at a desire downhole location, pivoting the flow monitoring sensor structure into the production fluid flow passage.
A system for monitoring parameters related to flow in a wellbore, comprising:
- a well component having an internal flow passage;
- a sensor structure mounted in the well component, the sensor structure having at least one sensor for monitoring a flow related parameter;
- and
- an actuator mechanism coupled to the sensor structure, the actuator mechanism being controllable to selectively move the sensor structure into and out of the internal flow passage.
