- PCPD progressive cavity positive displacement
- the well system 100 also includes a flow control device 130 disposed along or within the BHA 120.
- the flow control device 130 is disposed between a drilling fluid source and the motor 123 such that drilling fluid flows through the flow control device 130 before reaching the motor 123.
- the flow control device 130 is in a position to control the flow of drilling fluid into and through the motor 123.
- the drilling fluid source is located at the well site 106.
- the flow control device 130 if the pressure of the drilling fluid at the flow control device 130 is below a certain threshold pressure, the flow control device 130 permits substantially all of the drilling fluid to flow through to the motor 123. If the pressure of the drilling fluid exceeds the threshold pressure, the flow control device 130 diverts a portion of the drilling fluid away from entering the motor 123.
- the flow rate of drilling fluid across the motor can be held substantially constant, or at least within an acceptable range.

- FIG. 2 illustrates a top perspective view of a flow control device 200, such as the flow control device 130 of FIG. 1 , in accordance with example embodiments of the present disclosure.
- FIG. 3 illustrates a bottom perspective view of the flow control device 200, in accordance with example embodiments of the present disclosure.
- the flow control device 200 comprises a body 202 having a first end 204 and a second end 206.
- the flow control device 200 may be positioned such that the first end 204 is uphole of the second end 206.
- drilling fluid enters the flow control device 200 via the first end 204 and exits the flow control device 200 via the second end 206 before entering the motor 123.
- the first end 204 and second end 206 each include a surface.
- the body 202 includes a wall 212 extending from the entrance end 204 to the exit end 206.
- the body 202 of the flow control device 200 may have a cylindrical shape as shown. However, the flow control device 200 can have any shape.
- the flow control device 200 further includes a main flow path 210 formed through the body 202 extending between a first main opening 210a formed in the first end 204 to a second main opening 210b formed in the second end 206.
- the main flow path 210 traverses the entire length of the body 202, "length" being measured between the first end 204 and the second end 206.
- the main flow path 210 provides an open path for the drilling fluid to traverse the flow control device 200.
- the main flow path 210 may be a straight path or have curves and bends.
- the flow control device 200 also includes one or more bypass flow paths 208 formed through the body 202 and extending between a first bypass opening 208a formed in the first end 204 to a second bypass opening 208b formed in the second end 206. Similar to the main flow path 210, the one or more bypass flow paths 208 can generally have any shape that traverses the body 202 of the flow control device 200 and allows drilling fluid to flow through the flow control device 200. However, the bypass flow paths 208 are normally closed off, forcing all drilling fluid to flow through the main flow path 201 , unless the flow of drilling fluid exerts a high enough force on the flow control device 200, which indicates a higher than desirable fluid pressure. When such a condition occurs, the bypass flow paths 208 open and the fluid pressure is regulated. In some embodiments, each of the bypass flow paths 208 includes a valve 212 which controls opening and closing of the respective bypass flow path 208.
- FIG. 4 illustrates a perspective cross-sectional view of the flow control device 200, showing the internal structures of the flow control device 200 in more detail.
- the valve 212 is configured to move between a closed
- FIG. 4 shows the flow control device 200 in the closed configuration.
- the valve 212 When the valve 212 is in the closed configuration, the respective bypass flow path 208 is effectively closed off and drilling fluid cannot flow through the bypass flow path 208.
- the valve 212 can be is disposed within the respective bypass flow path 208.
- the valve 212 may form a barrier in the bypass flow path 208 when in the closed configuration which substantially prevents drilling fluid from flowing therethrough.
- the valve 212 includes a valve body 402 and a valve member 406 moveable in relation to the valve body 402.
- the valve 212 further comprises a spring 408 disposed between the valve body 402 and the valve member 406 such that the valve member 406 is supported by the spring 408.
- the valve 212 can be positioned within the bypass flow path 208 such that the valve member 406 plugs the first bypass opening 208a in the closed configuration. Specifically, the spring force of the spring 408 keeps the valve member 406 in such a position. In some embodiments, the spring 408 pushes the valve member 406 against a portion of the first end 204 around the first bypass opening 208a, thereby closing off the first bypass opening 208a. Thus, the bypass flow path 208 is closed by default, as illustrated in the cross- sectional view of FIG. 5. Referring to FIG. 5, the force exerted on the valve member 406 by the spring 408 is in the opposite direction as the force exerted on the valve member 406 applied by the injected drilling fluid.
- valve 212 remains closed unless the force of the drilling fluid overcomes the force of the spring 408.
- the valve member 406 is pushed away from the entrance end 204 by the drilling fluid, opening a space between the entrance end 204 and the valve member 406, through which drilling fluid enters the bypass flow path 208. The drilling fluid is thereby diverted from main flow path 210.
- the valve 212 may exhibit various degrees of openness, increasing with fluid pressure until the valve 212 is fully open. For example, a fluid pressure at or just above the threshold pressure may cause the valve 212 to open minimally, and a fluid pressure substantially greater than the threshold pressure may cause the valve 212 to open to a greater degree.
- the valve is a mechanically operated valve and is directly opened by the force of the fluid pressure.
- the valve may have discrete degrees of openness or continuous degrees of opening.
- the valve is an electrically operated valve, in which the valve includes a sensor which senses the fluid pressure or flow rate in the main flow path 210 and controls the openness of the valve electronically based on the sensed parameter.
- FIG. 6 illustrates a cross-sectional view of the flow control device 200 in which the valves 208 are in the open configuration.
- the closed configuration is the neutral state of the valve 212, and the valve 212 moves into the open configuration when a fluid pressure greater than a certain threshold pressure is exerted on the entrance end 204 of the body. If the pressure of the drilling fluid is not above a certain threshold, the valve 212 and bypass flow path 208 remain closed. Thus, under such conditions, substantially all of the drilling fluid flows through the main flow path 210 and into the motor 123 or power generation unit 125.
- the valve 212 when the pressure exerted by the drilling fluid is above the threshold, the valve 212 is configured to open the bypass flow path 208, allowing a portion of the drilling fluid to flow therethrough.
- the threshold pressure is indicative of a flow rate of the drilling fluid which is higher than selected for the motor 123 or power generation unit 125.
- the drilling fluid flowing through the bypass flow path 208 is routed through an auxiliary pathway separate from the motor 123 or power generation unit 125.
- the amount of drilling fluid flowing through the main flow path 210 and subsequently through the motor 123 or power generation unit 125 decreases. This decreases the flow rate of drilling fluid across the power generation unit 125 to a more selected level, such as for optimizing performance for example.
- the one or more valves 212 are poppet style valves. In other embodiments, the one or more valves 212 can be any type of valve configured to respond to the pressure, force, or flow rate, of the injected drilling fluid. Specifically, the one or more valves 212 may be pressure actuated valves or relief valves. In some embodiments, the valves 212 include flow rate detection means. One or more valves 212 can be mechanically actuated such that the force of the drilling fluid physically opens the valves 212, such as the example described above and in the figures. In some embodiments, the one or more valves 212 can be actuated (i.e., opened) electronically when it is sensed that the pressure, force, or flow rate of the drilling fluid exceeds a threshold.
- the flow control device 200 can include any number of bypass flow paths 208 and valves 212.
- the valves 212 can be configured to open at different pressure thresholds such that a portion of the valves 212 open at a first pressure threshold and another portion of the valves 212 open at a second pressure threshold.
- main flow path 210 there may be more than one main flow path 210.
- the main flow 210 may expand or contract in size at various positions.
- the main flow path 210 may be cylindrical in shape as shown in the figures.
- the main flow path 210 may be tubular such that it is bound by an outer wall and an inner wall.
- the main flow path 210 may be any shape or configuration that puts the entrance end 204 and the exit end 206 in fluid communication such that a drilling fluid can traverse the flow control device 200 through the main flow path 210.
