E, transfer locate successfully after, start drive motors (33), just changeing earlier 2～4 circles, reverse 35～55 ° again, shut down then; Promoting motor (18) moves once more; Continue to promote feed screw nut (13), outer sleeve (15) moves on continuing, and driving device pawl (38) outwards moves; When sensing chip (29) contact C (32) just in time is positioned at trigger region lower edge, travel switch (28) center; Travel switch (28) is connected once more, and chip makes its shutdown for lifting motor (18) instruction, and the idle stroke of outer sleeve this moment (15) is just all covered; Last sealing ring receives outer sleeve (15) thereby extruding realizes the sealing between outer sleeve (15) and the feed screw nut (13), and lower seal receives down pushing block (47) thereby the sealing between pushing block (47) and the last block (46) under the extruding realization; Simultaneously, gripper (38) achieves a butt joint with adjustable water nozzle (10) engagement;

After F, sealing and gripper (38) butt joint was all accomplished, drive motors (33) started, and carried out the water nozzle openings of sizes and regulated, and after regulating completion, shut down;

G, unlatching lifting motor (18) counter-rotating once more, leading screw (20) drives feed screw nut (13) and descends, and sensing chip (29) is decline thereupon also; Contact C (32), contact B (31) and contact A (30) are successively through connecing travel switch (28) center trigger region; When contact C (32) was positioned at trigger region upper edge, travel switch (28) center, travel switch (28) was connected, then contact C (32) the center trigger region of travel switch (28) of passing by; When it leaves near trigger region lower edge, switch center; Travel switch (28) cuts out, along with sensing chip (29) continues to descend, when the trigger region of the center of contact B (31) and contact A (30) process travel switch (28); In like manner, travel switch (28) process that all can once connect and close; When contact A (30) is left near trigger region lower edge, switch center, break off suddenly near switch, chip provides instruction lets lifting motor (18) shut down, and this moment, gripper (38) and mechanical positioning piece (25) were all regained.

13. the operating procedure of linked system is transferred in survey according to claim 11; It is characterized in that: described step F also comprises following operation; After carrying out the adjusting of water nozzle openings of sizes, let gripper (38) be opened to certain opening to water nozzle earlier, carry out the sealing of well head cable then; Toward the oil pipe water filling, be adjusted to the water nozzle opening size of design at last again.

14. the operating procedure of linked system is transferred in survey according to claim 11, it is characterized in that: described step F also comprises following operation: after regulating completion, and drive motors (33) counter-rotating 1～3 degree.

15. the operating procedure of linked system is transferred in survey according to claim 12; It is characterized in that: stop toward the oil pipe water filling, the well head cable is deblocking also, last portable cable; Let package unit pass through magnet (6) once more, and be positioned at the above 100～500mm of magnet (6).
