Hydraulic pump 30 operates the double acting cylinder 22 in the fluid tip 21 of equipment.Each hydraulic cylinder operation is located at the two of equipment A plunger in one of a fluid tip.
The typical construction of the equipment of the invention of the principle of the invention is shown now with reference to the flow chart description in Fig. 1.
Three systems for being respectively indicated to A, B, C are shown in FIG. 1.It should be understood that for clarity, scheming System C is only illustrated in detail in 1.The skilled person will understand that the components and functionality that reference system C is illustrated and described can also To be applied to system A and B.It is to be further understood that the present invention should not necessarily be limited by the quantity of system shown in Fig. 1.
Appended drawing reference 1 indicates power source, which includes prime mover 2.Prime mover can be gas-turbine unit or Reciprocating engine is controlled via (control fuel supplies F and receives the information about revolving speed R) throttle valve 3.Prime mover 2 It is connected to gear unit 8 and is configured to torque T being transferred to gear unit 8.Torque T ' is transferred to each liquid by gear unit 8 Press pump 9a to 9c；Each pump has corresponding pump pressure sensor 13a to 13c.
If prime mover 2 is combustion gas turbine, it is defeated that gear unit 8 can be configured to reduce the high revolving speed from turbine Out.If prime mover is another type of engine (such as reciprocating engine), hydraulic pump can be direct by engine Driving, and can be omitted gear unit 8.
Each hydraulic pump 9a to 9c is defeated to corresponding positive discharge capacity fluid via corresponding control valve 36a to 36c, 37a to 37c Send system supply hydraulic, positive discharge capacity fluid delivery system is double acting hydraulic cylinder 34a to 34c in the shown embodiment.Liquid storage Tank 11 and cooler 17 are fluidly coupled between hydraulic pump 9c and control valve 36c, 37c.The circuit further includes for easing off the pressure The accumulator 33 of pulse.
Each hydraulic cylinder 34a to 34c is drivingly connected to each group fluid plunger 35a1 to 35c1,35a2 to 35c2.Fluid Plunger 35a1 is to 35c1,35a2 to 35c2 via fluid supplies 10 to well supply fluid.However, the present invention is not limited to this streams Scapus plug.Appended drawing reference 12 indicates the suction line from fluid mixing system (not shown).
Well feedback pressure sensor 16 be connected to supply line 10 and the pressure that is configured in sensing supply line 10 (and therefore Sense pressure change).Valve outlet feedback pressure sensor 15 is connected to corresponding control valve 36c, 37c.Valve inlet pressure sensing Device 14 is connected to control valve 36c.Valve control 7 (usually programmable logic controller (PLC)-PLC), which receives, comes from pressure sensor 14,15,16 signal, the position feedback Cp from hydraulic cylinder, and control signal Vf is provided to control valve 36c, 37c.
Master control system 4 is based on power demand Pr control throttle valve 3 and provides power feedback Pf.Master control system 4 also connects Receive transportation safety interlocking feedback Ts from gear unit 8 and from PLC 7 based on being sensed by well feedback pressure sensor 16 To pressure change and the power consumption data EPC that estimates.Vent window controller 5 is also connected to master control system 4, with open and Close vent window (such as ventilation and fire-fighting).Master control system 4 receives the number for coming from hydraulic pump control device 6 (such as PLC) Power command Ac is provided according to and to hydraulic pump control device 6.Hydraulic pump control device 6 is based on (from pressure sensor 13c's) in turn It is pumped the discharge capacity needed for force feedback Pp is provided to hydraulic pump 9c and instructs Dc.Master control system 4 is also provided to valve control 7 about institute Need cylinder speed RCS data, the valve control 7 so as described above determine valve flow control signal Vf and to control valve 36c, 37c provides valve flow control signal Vf.
Therefore, the present invention includes the actuating unit of hydraulic/flow control, wherein the institute from prime mover is dynamic logical It crosses hydraulic pump and is converted into hydraulic power.Hydraulic pump enables prime mover to start in the case where overcoming very little or none load.
When equipment is in fracturing operation, prime mover 2 and hydraulic pump 9a to 9c operate hydraulic cylinder 34a to 34c and fluid The fracturing fluid that plunger 35a1 will be pressurizeed to 35c2 to 35c1,35a2 is supplied to line 10 (and therefore supplied to missile silo). The hydraulic frac pressure generated in well is the result of well pressure and the hydraulic pressure generated by plunger.(being sensed by sensor 16) Well pressure is transferred into valve control PLC 7, and valve control PLC 7 controls control valve 36a to 36c, 37a to 37c and goes back Determine that be transferred to master control system 4 estimates power consumption EPC.Prime mover fuel supplies (for example, turbine fuel injection) Therefore it can be controlled by well pressure, or more specifically be controlled by the pressure change continuously sensed by sensor 16.Burning Turbine fuel controller receive from hydraulic control system based on from hydraulic frac pressure pressure and rate reading Pressure reading.Then, hydraulic control system executes control based on the set point (rate/pressure) for being confirmed by operator and being set and moves Make.
In hydraulic unit intrinsic " delay " or be turbine fuel controller by " delay " that master control system 4 controls The thing that time enough will be occurred with " prediction " is provided, and is taken action before its generation.
This means that prime mover can increase fuel injection (opening throttle valve) before demand appearance as from hydraulic The requirements at the higher level of pump are prepared, or reduce the torque that fuel injection (limitation throttle valve) will be needed with the future for adapting to estimate, from And adapt to the variation of rate/pressure.The function is particularly useful in the embodiment that prime mover is gas-turbine unit, this is Because this turbine usually runs at high speed and has low torque.Control system can prevent combustion gas in this way Turbogenerator is overrun, and further such that gas-turbine unit has advantage in the increased torque-demand of prediction (head start)。
When the demand of fracturing fluid in well change or the actual consumption of fracturing fluid change and with by operating When person sets or is not consistent by the set point that overall system control determines, valve control 7 and pressure sensor 16 are based on sensing Pressure change sense such case.Set point is also based on deviation condition how is handled as defined in overall system control Priority processing table limits.Based on rate/pressure difference between set point and (as by 16 sensings) actual pressure readings, will go out (it is controlled existing (being fed to master controller 4 by pump controller 6) the practical power command Ac and power consumption EPC estimated by valve Device 7 is fed to master controller 4) different (being less than or greater than) the case where.This will lead to following situations: master controller 4 will incite somebody to action Control signal is provided to pump controller 6 and prime mover throttle valve controller 3, and can will be provided to pump controller 6 and original and be moved At the time of the control signal of machine throttle valve controller 3 control for simultaneously or with controlled difference, thus realize make it is former dynamic Machine is run in a manner of predicting.
Although describing the present invention referring to three hydraulic pumps it should be appreciated that the present disclosure applies equally to Less or more hydraulic pump.
Although describing the present invention referring to mobile unit it should be appreciated that the present disclosure applies equally to solid Locking equipment.
Although describing the present invention referring to driving fluid tip (double acting hydraulic cylinder) it should be appreciated that The present disclosure applies equally to by flow of pressurized and other pressure-actuated pumping theories, i.e. positive-displacement pump.Therefore, the present invention should not It is limited to double acting hydraulic cylinder.
