SHEAR SEAL CHECK VALVE FOR USE IN WELLBORE FLUID

摘要

An apparatus for controlling fluid flow that includes a chamber having a first valve and a second valve; a sensor that senses a pressure parameter associated with the chamber; and a controller programmed to operate the first valve and the second valve in response to the sensed pressure parameter may be used to control for flow and to obtain data relating to a formation and/or formation fluid. The apparatus may include a manifold for using a fluid mover to convey fluid between the first location and the second location and at least one module received by the manifold.

1. An apparatus for controlling fluid flow between a first location and a second location, comprising:
a body having a fluid conduit, the conduit having an inlet in fluid communication with the first location and an outlet in fluid communication with the second location, the body further having a chamber; a valve element disposed in the chamber, the valve element having a seal separating the chamber into a pressure section and a flow section, wherein the pressure section is in hydraulic communication with the outlet via an outlet fluid branch; a shear seal having at least one movable sealing element disposed on the valve element and at least one stationary sealing element disposed in the body; and a biasing member urging the valve element to a closed position wherein the at least stationary one sealing element is in sealing engagement with the at least one movable sealing element, wherein a pressure communicated by the outlet fluid branch also urges the valve element to the closed position.
