摘要： A downhole fluid flow control system includes a fluidic module (150) having a main fluid pathway (152), a valve (162) and a bridge network. The valve (162) has a first position wherein fluid flow through the main fluid pathway (152) is allowed and a second position wherein fluid flow through the main fluid pathway (152) is restricted. The bridge network has first and second branch fluid pathways (163, 164) each having a common fluid inlet (166, 168) and a common fluid outlet (170, 172) with the main fluid pathway (152) and each including two fluid flow resistors (174, 176, 180, 182) with a pressure output terminal (178, 184) positioned therebetween. In operation, the pressure difference between the pressure output terminals (178, 184) of the first and second branch fluid pathways (163, 164) shifts the valve (162) between the first and second positions.

摘要： A method of controlling a fluid jet can include discharging fluid through an outlet of a jetting device, thereby causing the fluid jet to be flowed in multiple non-coplanar directions, and the fluid jet being directed in the non-coplanar directions by a fluidic circuit of the jetting device. A jetting device can include a body having at least one outlet, and a fluidic circuit which directs a fluid jet to flow from the outlet in multiple non-coplanar directions without rotation of the outlet. A method of drilling a wellbore can include flowing fluid through a fluidic switch of a jetting device, thereby causing a fluid jet to be discharged in multiple non-coplanar directions from the jetting device, and the fluid jet cutting into an earth formation.

摘要： A variable flow resistance system can include a flow chamber through which a fluid composition flows in a well, the chamber having an inlet and an outlet. The fluid composition enters via the inlet in a direction which changes based on a ratio of desired to undesired fluid in the fluid composition. A well system can include a variable flow resistance system through which a fluid composition flows between a tubular string and a formation, the flow resistance system including a flow chamber through which the fluid composition flows, with only one chamber inlet. The fluid composition flows more directly from the inlet to an outlet as a ratio of desired to undesired fluid in the fluid composition increases. Another flow resistance system can include at least one structure which influences portions of the fluid composition which flow circuitously between the inlet and the outlet to maintain such circuitous flow.

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： A method for mixing at least two materials is provided. The method comprises introducing the at least two materials into a physical system and combining the at least two materials to form a mixture thereof. The method also comprises independently controlling a desired characteristic of the mixture and a desired parameter of the physical system, wherein the controlling is based in part on estimating a disturbance, wherein the estimating the disturbance is based on processing an error term determined by subtracting a modeled parameter of the physical system from a corresponding sensed parameter of the physical system.

摘要： Methods for managing the operational condition of flow control valves in process systems. As a control valve experiences mechanical wear during operation, the physical changes to the valve can alter its dead band and flow coefficient. A non-linear dynamic model determines the present dead band by modeling the relationship between the actual flow through the valve and the commanded drive signal to the valve. The present valve flow coefficient can be determined by removing the dead band from the drive signal and using that modified signal in a flow rate model for the valve to adaptively find the flow coefficient value which matches the predicted flow from the flow rate model to the present measured flow from a flow rate sensor. The present dead band and flow coefficient can be used to update valve control algorithms and to make valve maintenance decisions.
