Detailed description of the invention
Two preparations that the utility model will do before promoting tubing string:
1, the position that guard system got automatically by oil pipe is put: being placed in well head side by automatically getting guard system, should getting out of the way certain space to well head, do not interfere after mechanical arm of lying on the back (6) is lain down with the oil pumper of well head side; Meet after mechanical arm of lying on the back (6) is holded up under the support of mechanical arm action tank (7) of lying on the back again, through overregulating parallel-crank mechanism, making automatically to grab guard system (1) and vertical oil pipe can be caught.
2, the position of oil pipe Automatic Lay-out System is put: the position of oil pipe Automatic Lay-out System will meet two conditions: one, when mechanical arm of lying on the back (6) is caught after oil pipe lies down under the effect of mechanical arm action tank (7) of lying on the back, automatically guard system 1 half-twist under the effect of automatically grabbing guard system rotating mechanism (4) is grabbed, shift fork (17) will be lain on the back while motion not interfering mechanical arm of lying on the back (6), can by oil pipe from automatically grabbing guard system (1) dial-out; Its two, when ensure to drop on oil pipe bogey (14) after oil pipe is transferred to, do not occur partially to sink in tubing length direction.Oil pipe bogey (14) also will to have a down dip certain angle in the effect of oil pipe bogey tilt adjustment oil cylinder (15).
The utility model will experience oil pipe and lower oil pipe two working stages in well workover process.
Rise in the process of oil pipe at workover rig, this invention completes following action: mechanical arm of lying on the back (6) is holded up under the effect of mechanical arm action tank (7) of lying on the back, parallel-crank mechanism action tank (10) is regulated to make parallel-crank mechanism do action of protracting, automatically guard system (1) promptly oil pipe is grabbed, oil pipe automatic elevator unclamps oil pipe and up certain distance, regulates parallel-crank mechanism action tank (10) to make parallel-crank mechanism do retract action (as accompanying drawing 1).Mechanical arm (6) of lying on the back lies under the effect of mechanical arm action tank (7) of lying on the back lies on the back on mechanical arm bracing frame (16), tubing string moves up and down compensating cylinder (5) and regulates claw (12) to make it along vertical rigid guideway (13) horizontal movement, after driving oil pipe to arrive suitable position, automatically grab guard system (1) half-twist (as accompanying drawing 2) under the effect of automatically grabbing guard system rotating mechanism (4).Automatically grab guard system (1) and unclamp oil pipe, oil pipe is transferred to from automatically grabbing guard system (1) by shift fork (17) under the action of shift fork action tank (18), now oil pipe bogey (14) backward tilts at an angle under the effect of oil pipe bogey tilt adjustment oil cylinder (15), oil pipe rolls downwards along the oil pipe bogey (14) of inclination certain angle, in the upper order discharge of oil pipe bogey (14).Repeat above-mentioned action until oil pipe is all removed.
Under workover rig oil pipe process in, the action of this device has been the inverse motion of Tubing During Running action, oil pipe bogey (14) turns forward certain angle under the effect of oil pipe bogey tilt adjustment oil cylinder (15), oil pipe pushes from oil pipe bogey (14) and automatically grabs in guard system (1) by shift fork (17) under the action of shift fork action tank (18), automatically grabs guard system (1) and is firmly grasped by oil pipe.Automatically grab guard system (1) half-twist under the effect of automatically grabbing guard system rotating mechanism (4), make automatically to grab guard system (1) opening and become vertically from level.Mechanical arm (6) of lying on the back is become vertically from level under the effect of mechanical arm action tank (7) of lying on the back.Tubing string moves up and down compensating cylinder (5) and regulates claw (12) to make it move straight up along vertical rigid guideway (13), regulate parallel-crank mechanism action tank (10) to make parallel-crank mechanism drive automatically grab guard system (1) and do action of protracting, until the oil pipe captured in automatically grabbing guard system (1) and well head centering.Tubing string moves up and down compensating cylinder (5) and regulates claw (12) to make it move straight down along vertical rigid guideway (13), contact with the oil pipe in lower going-into-well until automatically grab the oil pipe that guard system (1) captures, next carry out pulling work on two oil pipes.Repeat above-mentioned action until oil pipe is all lowered to oil well.
Usefulness of the present utility model is: the full-automation achieving the oil pipe migration discharge process in well workover process, considerably reduces labor strength, decrease the quantity of labor needed for well workover scene, improve the safety of well workover process; The brief well-repairing work time, improve efficiency.
