When applying at the scene, rod tube coupling tunnel (5) is sling into decentralization with production rig；The epicone of suspension solution lock assembly (601) Body (60101) imports the lower docking passage (F) of rod tube coupling tunnel (5)；Slips ring (60104) is hung in the presence of external force along upper The inclined-plane of cone (60101) is descending, and the external diameter of suspension slips ring (60104) diminishes, into lower docking passage (F)；When suspension solves After lock assembly (601) enters the suspension cavities (D) of rod tube coupling tunnel (5), upper shadoof pipe coupling tunnel (5), suspension slips ring (60104) It is up along the inclined-plane of upper cone (60101) in the presence of back-moving spring (60105) strength, outside suspension slips ring (60104) Footpath becomes big, is suspended on the suspension face (E) of suspension body (503)；When needing unblock, the epicone of suspension solution lock assembly (601) is above carried Body (60101), suspension slips ring (60104) contact with the anti-top surface (C) of rod tube coupling tunnel (5), continue above to propose suspension unblock always Into upper cone (60101), suspension slips ring (60104) it is descending along the inclined-plane of upper cone (60101) in the presence of external force, hang The external diameter of a watt ring (60104) of hanging tag diminishes, and into upper docking passage (B), completes unblock, until proposing rod tube coupling tunnel (5)；

When applying at the scene, after the completion of tappet tripping in, the piston limit cylinder (60208) of anti-top solution lock assembly (602) passes through screw thread It is connected with suspension solution lock assembly and tappet；On watch out for top solution lock assembly (602) anti-top cone (60201), anti-jack slips ring (60202) descending along the inclined-plane of anti-top cone (60201), the external diameter of anti-jack slips ring (60202) is reduced to minimum；Use workover treatment Rod tube coupling tunnel (5) is sling decentralization by machine；Anti- top solution lock assembly (602) imports the lower docking passage of rod tube coupling tunnel (5), finally Into the suspension cavities of rod tube coupling tunnel；The anti-top cone (60201) of anti-top solution lock assembly (602) is pushed with external force, pushes up slips ring (60202) up along the inclined-plane of anti-top cone (60201), anti-jack slips ring (60202) struts, and completes anti-top operation；Rod tube joins Connect cylinder (5) top connected pipes, precalculated position is transported to by tappet and tester；When needing unblock, it is total above to watch out for top unblock Into the anti-top cone (60201) of (602), inclined-plane of the anti-jack slips ring (60202) along anti-top cone (60201) is descending, anti-top card The external diameter of watt ring (60202) is reduced to minimum, and anti-top solution lock assembly (602) can propose out of rod tube coupling tunnel (5), complete solution Lock.
9. usage right requires the horizontal well rod tube conveying of the horizontal well rod tube conveying well measuring technique rod tube post of 1 to 4 any one Application method, it is characterised in that：

After the completion of tappet tripping in, suspension solution lock assembly, anti-top solution lock assembly, pin end assembly (701) are connected with tappet successively Connect；Rod tube coupling tunnel is sling with production rig；Pin end assembly (701), anti-top solution lock assembly, suspension are solved into lock assembly, The suspension cavities of rod tube coupling tunnel are guided into successively, complete suspension；Rod tube coupling tunnel top connecting test tubing string, by tester It is transported to precalculated position；Female joint assembly (702) is connected with test cable, from oil pipe tripping in；Female joint assembly (702) reaches public During connector assembly (701) 50~100m of top, with 2000~4000m/h rate discharge cable, until cable stretch reduce 1~ 5kN, stop lower payout, keep the static 1~2min of cable, complete the docking of cable butting device；With 50m/h~100m/h speed Upper portable cable, complete tappet suspension solution lock assembly unblock；With portable cable in 300m/h~800m/h speed, tested；Survey After the completion of examination, upper portable cable, whole test cables, horizontal wellbore logging cable butt joint device, anti-top solution lock assembly, outstanding are played out successively Hang solution lock assembly, tappet and tester；Test string docking, deblocking, act down-hole string and rod tube coupling tunnel.
