Figure 20 has described according to the phantom of the downhole tool 26 of one or more embodiment, wherein, shows the rotation finger valve module 242 that is connected to motor module 42.Valve module 242 is arranged in the receiving structure 100 of downhole tool 26 the inner surface sealed engagement to make seal 76 and receiving structure 100.Port one 02 (not shown) can be arranged in the receiving structure 100 of downhole tool 26 and extend through the receiving structure 100 of downhole tool 26.In finger valve 272 can be rotatably set in receiving structure 100, when allowing fluid to be communicated with, the port 202 in the base-plates surface 252 of port one 02 (not shown) and the idler axle 254 of valve chest 250 is aimed to make between chamber 112 and the hole 106 of downhole tool 26, to set up fluid and be communicated with manipulating.When port one 02,202 by pressure fluid from hole 106 by manipulation chamber 112 while sending actuation member 104 to, pressure enough large fluid is used for mobile actuation member 104 and thus downhole tool 26 is manipulated to the duty of another expectation.In order to rotate finger valve 272, motor 82 drives the motor drive shaft 41 that is connected to motor connector part 68 ', rotarilys actuate thus valve connector part 278 and applies and rotatablely move to finger valve 272.Motor connector part 68 ' is illustrated and holds and be oriented in valve connector part 278 to form complete self-aligning connector 84 '.

Figure 21 has described according to the phantom of the downhole tool 26 of one or more embodiment, wherein, show rotation finger valve module 242 in the first manipulation position, Figure 22 has described according to the phantom of the downhole tool 26 of one or more embodiment, wherein, show rotation finger valve module 242 in the second manipulation position.In Figure 21, valve module 242 is illustrated in the close position, that is, finger valve 272 is arranged to make to refer to 275 blocking-up by the mobile of port 202 and block thus drilling fluid/mud to flow to the manipulation in manipulation chamber 112.Before downhole tool 26 is by manipulation, as shown in the flow arrow 220 of Figure 21, drilling fluid/mud is pumped down by hole 106, by the axially open 210 (Figure 18-2) in finger valve 272, between self-aligning connector 84 ' and spring retainer 276, flow, then along motor module 42 outsides, route flows to drill bit 36 (Figure 17) in accordance with regulations.The pressure of the drilling fluid/mud in hole 106, for example pressure of drill string 22 inside, higher than the pressure of the drilling fluid/mud in well 24, for example pressure of drill string 22 outsides.As example, the pressure in hole 106 can be than the pressure in well 24 high 800psi to 1,000psi.Therefore, between hole 106 and well 24, downhole tool 26 both sides have a pressure reduction.When valve module 242 is during in make position shown in Figure 21, this pressure reduction of rotation finger valve module 242 use of Figure 18-1 produces the effective sealing to port 202.

As shown in Figure 18-2, the surface area of the soffit 271 of finger valve 272 is greater than the combination table area of multiple upper surfaces 273 of the finger 275 of finger valve 272.In addition, in the make position of Figure 21, the soffit 271 of finger valve 272 is exposed under the elevated pressures in hole 106, and refers to that 275 upper surface 273 is exposed under the lower pressure in manipulation chamber 112.In this embodiment, manipulation chamber 112 is under borehole pressure, because manipulation chamber 112 is communicated with well 24 fluids by nozzle 111 (Figure 20).Thus, owing to being exposed to the surface area of the soffit 271 under the elevated pressures in hole 106 and being greater than the combination table area of the upper surface 273 under the lower pressure that is exposed to well 24, therefore the clean power of pressure reduction can upwards promote finger valve 272.This power upwards makes to refer to that 275 upper surface 273 keeps being seated on the base-plates surface 253 on the idler axle 254 of valve chest 250, has strengthened thus the sealing to port 202.Therefore, rotation finger valve module 242 adopts pressure reduction to strengthen sealing, and this has stoped the leakage occurring by port 202 in the time that valve module 242 is in the close position, prevents thus by mistake to manipulate downhole tool 26.

Totally, with reference to Figure 22, the rotation finger valve module 242 of Figure 18-1 is illustrated in an open position, and finger valve 272 is arranged to make to refer to that 275 open the flow path by one or more ports 202 and allow drilling fluid/mud to flow to manipulation chamber 112.In the time that appropriate control signal is passed/is sent to down-hole arrival electronic device 80 (Figure 12), make it arrive the open position (or in contrast) shown in Figure 22 before from make position shown in Figure 21 in motor module 42 movement of valve modules 240, be stopped from the pumping of the drilling fluid/mud on ground.Now, the pressure in hole 106 is identical with the pressure in well 24, makes not exist on downhole tool 26 pressure reduction.Then motor module 42 rotation motor axles 41 to be to apply and to rotatablely move to finger valve 272 thus, and this makes to refer to that 275 are moved and are separated from and open by the flow path of port 202 from one or more ports 202.In this manner, motor 82 needn't overcome the next finger valve 272 in rotary moving of difference force.In this rotary course, electronic device part 80 (Figure 12) can be monitored the electric current of the motor 82 that is used to indicate valve module position.Especially, in the time of the engaged at end of pin 216 and control flume 214, the electric current of motor 82 will produce spike, this represent valve module 242 from open position move to stride across port 202 make position (, stop by port 202 and enter flowing of manipulation chamber 112), or move to open position (, allowing to enter flowing of manipulation chamber 112 by port 202) from make position.Once valve module 242 has moved to open position as shown in figure 22, drilling fluid/mud is pumped down by hole 106 and outwards acts on actuation member 104 by port 202, as shown in the flow arrow 225 of Figure 22, cutter group 28 (Figure 17) (or other tool operation) is transformed to the state of expectation.

In one or more embodiments, the rotation finger valve module 242 of Figure 18-1 is designed to make to refer to substantially maintain Continuous Contact between 275 upper surface 273 and base-plates surface 253, no matter in the close position the or open position of valve module 242.At the open position shown in Figure 22, pre-compressed spring 274 applies enough power to maintain this contact between finger 275 and base-plates surface 253 to finger valve 272.Interaction between finger 275 and the port 202 of base-plates surface 253 and the interaction between rotor and stator are similar, for allowing or stoping fluid from flowing through between the two.Therefore, have and refer to that 275 valve 272 can be characterized as being rotor and the base-plates surface 253 with port 202 can be characterized as being stator.

In the example of describing in the above, rotatablely moving of finger valve 272 is designed to expose one or more bypass port 202, and this allows the fluid/mud of transfer to flow to manipulation chamber 112 and activates cutter group 28 (or other tool operation) to promote actuation member 104.Being further rotated of finger valve 272 makes to refer to that 275 align to seal bypass port 202, flow (spring-biased producing with the spring 130 of Fig. 9 is combined simultaneously) and can force actuation member 104 to return to its rest position owing to lacking transfering fluid, the expansion of cutter group 28 (or other tool operation) is stopped thus.Therefore, as mentioned above, control system 30 ' (Figure 17) can be activated as required and stop using, to manipulate/to stop downhole tool 26.In addition, use self-aligning connector part 278,68 ' to contribute to assemble at the scene and use rotation finger valve module 242 and motor module 42.The electronic device part 80 (Figure 12) comprising is further convenient to optionally activate motor 82 with long-range down channel in the time expecting that finger valve 272 moves.Position sensing 50 can also be incorporated in control system 30 ' with the movement of monitoring finger valve 272 and for example control system transmission/transmission information earthward.
