The course of work of the present invention is as follows:
One, prepare before pilot production
Before carrying out production testing operation, multiple pilot production unit (in Fig. 6 being 5) is placed in each well head, by fot screw, pilot production unit skid base 26 is fixed on ground, corresponding with power unit for the hydraulic quick coupler of each pilot production unit hydraulic quick coupler is connected.Open diesel-driven generator 28 or be connected with power supply by equipment, driving variable pump 19 synchronous axial system by variable pump motor 18, power unit programmable logic controller (PLC) 15 exports control signal with the output flow of regulated variable pump 19 to the stroking mechanism of variable pump 19.Successively the second three position four-way directional control valve of each pilot production unit is placed in right position, variable pump 19 is to support oil cylinder 3 rodless cavity topping up, and support oil cylinder 3 piston rod stretches out and supports oil pumping support 24 to be holded up.After oil pumping support 24 is holded up, second three position four-way directional control valve is placed in meta, and successively the first three position four-way directional control valve of each pilot production unit is placed in right position, variable pump 19, to the hydraulic cylinder 1 rodless cavity topping up driving the oil pumping support that slides flexible, drives flexible hydraulic cylinder 1 piston rod of sliding support to stretch out and drives the oil pumping support that slides to stretch out.After the oil pumping support that slides stretches out completely, the first three position four-way directional control valve is placed in meta.
Two, sucker rod is descending:
Pilot production unit programmable logic controller (PLC) 4, according to the running parameter of artificial input and actual condition, exports control signal to hydraulic transformer 5 and two-bit triplet reversal valve 6, low speed high torque hydraulic motor 7 is rotated.The output flow of hydraulic transformer 5, according to trapezoidal planning curvilinear motion, avoids hydraulic shock during commutation, makes sucker rod easy motion simultaneously.When pilot production unit programmable logic controller (PLC) 4 by the signal of speed probe 8 calculate sucker rod reached up predetermined stroke time, pilot production unit programmable logic controller (PLC) 4 exports reduction flow signal to hydraulic transformer 5, makes low speed high torque hydraulic motor 7 drive winch 9 to slow down.When speed probe 8 detects that winch 9 rotating speed is zero, two-bit triplet reversal valve 6 switching position, increase the output flow of hydraulic transformer 5, make low speed high torque hydraulic motor 7 drive winch 9 to accelerate to turn to setting speed value, winch 9 drives sucker rod to decline by wire rope 23 simultaneously.Sucker rod gravity acts on winch 9 by wire rope 23, jointly high-speed hydraulic pump/motor 12 is driven to rotate with low speed high torque hydraulic motor 7, in accumulator 11, be filled with high-voltage oil liquid, thus motor done work and the recovery of sucker rod gravitional force, reduce installed power.
Three, sucker rod is up:
When pilot production unit programmable logic controller (PLC) 4 by the signal of speed probe 8 calculate sucker rod reached descending predetermined stroke time, pilot production unit programmable logic controller (PLC) 4 exports reduction flow signal to hydraulic transformer 5, makes low speed high torque hydraulic motor 7 drive winch 9 to slow down.When speed probe 8 detects that winch 9 rotating speed is zero, two-bit triplet reversal valve 6 switching position, increases the output flow of hydraulic transformer 5 simultaneously, makes low speed high torque hydraulic motor 7 oppositely accelerate to setting speed value; High-voltage oil liquid in accumulator 11 drives high-speed hydraulic pump/motor 12 to rotate backward, low speed high torque hydraulic motor 7 and high-speed hydraulic pump/motor 12 drive winch 9 to drive polished rod eye 25 to rise by wire rope 23 jointly, thus drive the sucker rod be connected to below polished rod eye 25 to rise.Sucker rod rises by the oil exploitation in oil well to ground, thus completes one action circulation.High-speed hydraulic pump/motor 12 and accumulator 11 form hydraulic counterweight jointly.Repeating second and third step makes sucker rod constantly move up and down, until production testing operation completes.
Four, Postharvest handling is tried
After production testing operation terminates, successively each pilot production unit first three position four-way directional control valve is placed in left position, variable pump 19 passes through the first three position four-way directional control valve to the hydraulic cylinder 1 rod chamber topping up driving the oil pumping support that slides flexible, makes flexible hydraulic cylinder 1 piston rod of driving slip oil pumping support drive the retraction of oil pumping support.After slip oil pumping support is retracted, first three position four-way directional control valve is placed in meta, successively each pilot production unit second three position four-way directional control valve is placed in left position simultaneously, variable pump 19 is by the second three position four-way directional control valve to support oil cylinder 3 rod chamber topping up, and support oil cylinder 3 piston rod drives oil pumping support 24 to fall down.After oil pumping support 24 falls down, the second three position four-way directional control valve is placed in meta, and closes diesel-driven generator 28 or cut off externally fed power supply, pilot production Whole Equipment can be transported to subsequent work place.
