The course of work of the present invention is as described below:
Scene one:It is matched with armored cable
It is fixedly mounted on after motor 2-2 and retarder 2-3 is coaxially connected in motor room housing 2-1, cable core is worn
The power cord that top connection 1 is crossed with motor 2-2 is connected, and top connection 1 is socketed on motor room housing 2-1, power set its
Remaining assembly method completes the assembling of electric drive casing patching power set as described in said program.
The trip nonyl 5-5 in electric drive casing patching power set in the present embodiment connects with subsequent subsidy pipe device
It connects, the top connection 1 in electric drive casing patching power set is connected with the halter on armored cable, internal wire connects
It is logical, electric drive casing patching power set and subsidy pipe device are transmitted to by underground by cable and treat that position is reinforced in subsidy, by
Ground motor control module control motor 2-2 work, passes through the worm drive adjutant of sleeve nut 3-2 and screw rod 3-3 compositions
The torque of motor 2-2 outputs is changed into axial force so that trip nonyl 5-5 can drive subsequent parts axially reciprocating.
Top connection 1 is connected with the halter on armored cable, first by patching tube tripping in well head, then with the big hook block of workover rig
The electric drive casing patching power set for being connected to cable are acted, then by the trip of electric drive casing patching power set lower end
Nonyl 5-5 is threadedly attached on the trip nonyl connector sleeve of subsidy pipe device upper end, then will swim nonyl 5-5 locks with trip nonyl locking nut
Tightly, the snap-gauge in upper tapered sleeve is removed, the setting cylinder 5-6 of backspin electric drive casing patching power set lower end, makes setting afterwards
Cylinder 5-6 is connected with the upper tapered sleeve erecting device in subsidy pipe device, and tightening setting cylinder locking nut 5-8 prevents from releasing, and completes electricity
Power drive sleeve is subsidized in whole system lower going-into-well after power set and the connection for subsidizing pipe device, with cable by electric drive
Casing patching power set and subsidy pipe device are delivered to position to be subsidized.
It is measured according to the measuring instrument carried on the cable of transmission subsidy system and accurately adjusts the position of patching tube, confirmed
It is worked after errorless by the motor 2-2 in ground motor control module startup electric drive casing patching power set, in electricity
Upper and lower tapered sleeve is squeezed into the anchor mechanism at patching tube both ends under the promotion of power drive sleeve subsidy power set, make patching tube
Upper and lower end anchor mechanism swells, and formed win cooperation with casing, and realized anchoring, the sealing function of patching tube.
Motor 2-2 works on, and axial force also constantly increases, when upper and lower tapered sleeve is acted on anchor mechanism
When radially dilating power and anchor mechanism, casing and stratum and balancing each other to their restraining force, anchor mechanism stopping swells, at this point,
Stopping axially moves, and the axial force of the secondary output of worm drive all acts on the ring of giving up in lower tapered sleeve erecting device
On, when the pulling force of pull rod reaches the destruction value of thrust for ring of giving up, ring of giving up fracture realizes erecting device unfreezing of trapping, at this time
Ground motor control module stops the work of motor 2-2, and whole device is finally proposed to construction well together with cable, completes to mend
Paste seal of tube anchoring.When transmitting patching tube using armored cable, conveying can be realized by concatenating Depth Meter on cable
It is once completed with measurement check and correction patching tube depth, easy construction.
Scene two:It is matched with oil pipe:
Top connection 1 can also be connected with existing oil pipe, can be converted to tubing transmission pattern, be driven electric power by oil pipe
Dynamic casing patching power set and subsidy pipe device are transferred to subsidy and reinforce position, and using ground caber, caber, which prolongs in oil pipe, to be led to
Road, which falls, hits firing pin, impact force breaking pin, and firing pin moves down triggering and hits electric switch unit connection circuit so that electric power drives
The motor 2-2 of dynamic casing patching power set starts to work, and starts electric drive casing patching by way of caber shock and moves
Power apparatus completes casing patching.
In the prior art the hydraulic power of coiled tubing transmission can also be used to be subsidized, since one piece shapes
Coiled tubing manufacture it is of high cost, therefore complete equipment cost of use is big.Tubing transmission electric drive casing is used in the present invention
Oil pipe is connected without seal and pressure bearing requirement during patch device, simplifies construction requirement, reduces operating expenses.
