Five, embodiment
The utility model is by steyr automobile 1, be installed in the preceding hydraulic pump of compartment board, the storage battery 3 of compartment board middle part one side, the flash welder 4 of compartment board rear portion one side, the hydraulic line 5 that connects hydraulic pump and lifting grasping drive unit, coiled rod is from the conduit 6 of reel 11 guiding lifting grasping drive units 10, drag the trailer 7 of reel, hang the crane 8 of lifting grasping drive unit, being located in the wellhead blowout preventor 9 of lifting clamper forms, it is characterized in that the lifting grasping drive unit is located on the wellhead blowout preventor, hang height by crane, conduit is hung by crane and is suspended between reel and the lifting grasping drive unit, output shaft one end at the motor of steyr vapour, a QF60 type total power power takeoff is set, the power of its motor is become the hydraulic pressure energy by set hydraulic pump, be connected by fluid pressure line between hydraulic pump and the lifting grasping drive unit;
The coiled rod lifting clamping device includes the hydraulic drive motor 10.1 at its back side, the gearbox 10.2 below the hydraulic motor, and positive axis bilateral symmetry is provided with a sets of transmission mechanism and the right chain pressing mechanism and following safety card mechanism thereof.Chain drive is by 4 symmetrical up and down sprocket wheels 10.3, the symmetric support plate 10.8 of the right and left, the two ends at middle part have the pressure rod 10.5 and the gimmal 10.6 of the symmetry of roller and form, the gimmal chain is on pressure rod, big chain 10.4 passes through the gripper shoe chain separately on last lower sprocket 10.3, the big chain 10.3 in axis both sides pastes mutually with gimmal 10.6, and the top of the pressure rod on the right, middle part, bottom link to each other with the hydraulic cylinder case of three same specifications separately; Safety card mechanism is made up of symmetrical two hydraulic cylinders 10.14 and the monosymmetric fixture block that has tooth of axis that are located at safety 10.13 back sides.Hydraulic cylinder 10.14 acts on the fixture block.
Remove the operation sequence of coiled rod:
1, the location of working rig
Working vehicle checks whether put oil pipe, sleeve pipe gas earlier behind the well site.If do not have venting, flame-out car earlier, put oil pipe, sleeve pipe gas then, closed shutter.Working vehicle 1 is in place, and the working rig center line aligns with the well head center line as far as possible, and the working rig rear bumper is apart from well head 90～100m.
2, primer fluid pressing system
After the shutdown button in the driver's cabin is beaten in the hydraulic work system position, pressed the power takeoff key.At power operation monitor dial plate power takeoff several times repeatedly, guarantee that power takeoff safety hangs up.Start up the car 1, power takeoff is passed to hydraulic pump 2 with torque.
3, prop hydraulic leg 4
Hydraulic leg pulled out put in place, place sheeting caps and iron cushion block under hydraulic leg, hydraulic pressure is propped supporting leg.Observe the level gauge of working rig, working rig is horizontal.
4, hang the lifting grasping drive unit with crane
Sling with crane 8 and to be placed on lifting grasping drive unit 10 in the working vehicle, be located on well head side's spray apparatus, make its center line aim at well head, angled conduit 6 with another of crane 8, the other end that the one end is fixed on the trailer 7 is fixed on center, lifting grasping drive unit upper end, coiled rod is passed conduit and lifting grasping drive unit, be connected, check in the working vehicle that the pressure meter on the instrument board is whether in job area with the pump piston joint.
When 5, descending coiled rod, " up pressure " relief valve must be transferred to maximum (turning clockwise on earth), and " descending pressure " relief valve is transferred to the pressure that coiled rod is descended.
6, the centering shift fork is pushed the operating position, begin coiled rod down.Hydraulic pump 12 is passed to hydraulic motor 10.1 with hydraulic pressure, and hydraulic motor 10.1 becomes hydraulic coupling into mechanical force and passes to sprocket wheel 10.3 after by gearbox 10.2 speed changes, and the right, left side chain 10.4 rotates.Being lowered to half speed of preceding 100 meters usefulness, gather way then, but be no more than 30 meters/minute.Notice that sucker rod should be at the positive center of well head.
7, pressure rod 10.5 pressure should be adjusted to the downslide that prevents coiled rod and exceed.The manometric numerical value that pushes big chain 10.4 generally speaking is not lower than up pressure value (psi), in case the coiled rod that skids can send the sound that collides with, should heighten squeeze pressure rapidly until working properly this moment.It's the life-span that the lifting clamping device parts are shortened in conference is past pressure.Along with the increase of sucker rod depth of setting can constantly increase extruding force.
8, the chain 10.4 on the left side drives gimmal 10.12, and minor sprocket 10.12 drives counter 10.11, observes counter 10.11 readings.At the sucker rod depth of setting during apart from dark 100 meters of pump, slowly.Be honored as a queen when the oil pumping pump seat, " up pressure " descends rapidly, is close to zero.Rise repeatedly, transfer three times, guarantee the real seat envelope of oil well pump.Observe meter reading simultaneously, whether checking reaches collapses the extension degree of depth.
9, measure preventer, well head threeway and packing box size, do a mark above the packing box relevant position, measure the size of the sucker rod top connection that needs welding then, polished rod length adds that the rod connector size is sucker rod and proposes size.Promote coiled rod with lifting clamping device 10, measure out the size that will propose, on coiled rod, make mark (using hacksaw) with rice.When oil well surpassed 2440 meters, label size was added 60 centimetres; Oil well is below 915 meters the time, and mark is added 30 centimetres.
10, trip out coiled rod with lifting clamping device, rollback makes to mark outside the present guiding mouth of pipe to the transport vehicle reel.Fix unnecessary coiled rod with iron wire, fix guide pipe simultaneously, hurt sb.'s feelings when preventing sawed-off continuous bar.
11, continuous bar is pulled to flash welder, the welding top sub.Put the blowout prevention clamp this moment on wellhead blowout preventor, stamp two coiled rod clamps.
12, treat that top sub welding finishes, on top sub, load onto seeker, coiled rod is exposed 6 mouthfuls of guide pipes to top connection down, appear at above the lifting clamping device, mention the lifting grasping drive unit with crane.Stamp two coiled rod clamps at well head, make the coiled rod seat at well head.On carry coiled rod,, more gently the coiled rod seat at well head, observe the coiled rod clamp and whether skid.As skid, need fastening again sucker rod clamp.
Transfer coiled rod, make the crane seat on preventer.On top sub, connect sucker rod substitute, mention coiled rod.Preventer is put pressure, tears pipeline open, unloads preventer and improves lifting sub.
13, put packing box and well head threeway in proper order in the polished rod lower end.Mention polished rod with crane, connect polished rod, must guarantee that when carrying polished rod packing box, threeway and clamp etc. on the polished rod all at the polished rod lower end, hurt sb.'s feelings in order to avoid fall after improving.Lead oil is used in attention in rod connector, screw thread must tighten.
14, watch out for polished rod fast with crane, determine position at the bottom of the pump.When polished rod was transferred, the operator is placed on hand can feel vibrations on the polished rod, at this moment made a mark rapidly on polished rod.Repeatable operation has been determined position at the bottom of the pump several times.Measure the distance of polished rod box cupling with tape measure to the vibrations mark.
15, with carrying lever on the crane, reserve dead space.Pump hangs over below 1524 meters and proposes 30.5 centimetres, and pump is hung and surpassed 46 centimetres of 1524 meters propositions.The side's of stamping clamp on packing box unclamps the crane hook, unloads to promote the well head bolt, and box cupling guarantees the well head no leakage.The whole operation of coiled rod down finishes.
