摘要： Apparatus and methods for controlling the flow of fluid, such as formation fluid, through an oilfield tubular positioned in a wellbore extending through a subterranean formation. Fluid flow is autonomously controlled in response to change in a fluid flow characteristic, such as density or viscosity. In one embodiment, a fluid diverter is movable between an open and closed position in response to fluid density change and operable to restrict fluid flow through a valve assembly inlet. The diverter can be pivotable, rotatable or otherwise movable in response to the fluid density change. In one embodiment, the diverter is operable to control a fluid flow ratio through two valve inlets. The fluid flow ratio is used to operate a valve member to restrict fluid flow through the valve.

摘要： An apparatus is described for controlling fluid flow in a downhole tubular. Fluid is flowed through a flow control system having a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, where the ratio of fluid flowing through the passageways dependent on a characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first inlet directing flow primarily tangentially into the vortex chamber and the second inlet directing flow primarily radially into the vortex chamber. Undesired fluids, such as gas or water, in an oil well, are directed, based on their relative fluid flow characteristics, into the vortex primarily tangentially, thereby restricting flow when the undesired fluid is present.

摘要： A well tool can comprise a fluid input, a fluid output and a fluidic oscillator which produces oscillations in a fluid which flows from the input to the output. The fluidic oscillator can include a vortex chamber with inlets, whereby fluid enters the vortex chamber alternately via the inlets, the inlets being configured so that the fluid enters the vortex chamber in different directions via the respective inlets, and a fluid switch which directs the fluid alternately toward different flow paths in response to pressure differentials between feedback fluid paths. The feedback fluid paths may be connected to the vortex chamber. The flow paths may cross each other between the fluid switch and the outlet.

摘要： An apparatus is described for controlling flow of fluid in a tubular positioned in a wellbore extending through a subterranean formation. A flow control system is placed in fluid communication with a main tubular. The flow control system has a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, the production fluid flowing into the passageways with the ratio of fluid flow through the passageways related to the characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first and second inlet and an outlet, the first inlet of the pathway dependent resistance system in fluid communication with the first passageway of the fluid ratio control system and the second inlet in fluid communication with the second passageway of the fluid ratio control system. The first inlet is positioned to direct fluid into the vortex chamber such that it flows primarily tangentially into the vortex chamber, and the second inlet is positioned to direct fluid such that it flows primarily radially into the vortex chamber. Undesired fluids, such as natural gas or water, in an oil well, are directed, based on their relative characteristic, into the vortex primarily tangentially, thereby restricting fluid flow when the undesired fluid is present as a component of the production fluid.

摘要： When a first liquid fed into a first flow passage 6 moves therein toward a connecting portion 10 due to capillarity, gas in the first flow passage 6 is pushed by the moving first liquid to be exhausted to the external environment via a third flow passage 14 and an external environment communication passage 8, so that the first liquid moves to the end of a fifth flow passage 16, which is formed in the connecting portion 10, on the side of a second flow passage 7 due to capillarity. Then, when a second liquid fed into the second flow passage 7 moves therein toward the connecting portion 10 due to capillarity, gas in the second flow passage 7 is pushed by the moving second liquid to be exhausted to the external environment via a fourth flow passage 15 and the external environment communication passage 8, so that a liquid-liquid interface level between the first and second liquids is formed in the connecting portion 10.
