Carbon fiber continuous flexible sucker rod implement
Technical field
The invention belongs to oil extraction in oil field technical field, particularly relate to a kind of carbon fiber continuous flexible sucker rod implement.
Background technology
Sucker rod is a kind of equipment conventional in process of oil production, during oil recovery, is driven the oil pumping of down-hole by sucker rod
Pump pump rod pumps, thus by liquid pumpings such as the oil in stratum to ground.In use, generally will take out
Beam hanger is connected to km, in this case, and self suspending weight that sucker rod is to be born and the load of oil well pump, therefore bear
Pulling force is bigger.Carbon-fiber continuous rod, it is excellent that this sucker rod utilizes carbon fiber light weight, good toughness, tensile strength high etc.
Physical property more and make, and this sucker rod has torque resistant performance, anti-wear performance.So rise, lower flexible oil pumping
Need during bar specialty implement rise, lower flexible rod.Steel sucker rod is installed now is by artificial one section one section
Linked together by connector, make one section of one section of ground of sucker rod extend to down-hole in connection procedure, this mode and equipment
Be not suitable for carbon fiber continuous flexible sucker rod.

Detailed description of the invention:
Below in conjunction with example, the present invention is described further:
The application carbon fiber continuous flexible sucker rod implement, this equipment includes two pieces of arcs 11, two pieces of arcs
11 be arranged in parallel, and arranging of two pieces of arcs 11 determines that the track that carbon fibre pumping rod 17 runs thereon is arc track, protect
Demonstrate,prove carbon fibre pumping rod 17 by horizontal direction smoothly transitting to vertical direction, between the two ends of arc 11, be fixed with base plate
7, it is fixed with gripper shoe 6, base plate 7 and gripper shoe 6 between base plate 7 and arc 11 and two pieces of arcs 11 is played fixing and support
Effect, between two pieces of arcs 11, uniform intervals is provided with rotary shaft 8, rotary shaft 8 outer wall set rubber sleeve 9, rotary shaft 8 He
Rubber sleeve 9 constitutes the operation track of carbon fibre pumping rod 17, and rotary shaft 8 can rotate together with rubber sleeve 9, and carbon fiber is pumped
Bar 17 rolls rubber sleeve 9 during moving ahead and reduces the friction between carbon fibre pumping rod 17 and rubber sleeve 9 and frictional resistance, protects
Card carbon fibre pumping rod 17 runs smooth and easy the most frayed, and during oil well operation, the surface of rubber sleeve 9 is that arc is pumped close to carbon fiber
The shape of bar 17 outer wall, it is ensured that carbon fibre pumping rod 17 is walked at the middle part of rubber sleeve 9 in running, and left and right play will not occur,
Ensure that the running orbit of carbon fibre pumping rod 17 does not changes, one end of two pieces of arcs 11 is hinged with support 10, support
Two pieces of arcs 11 are propped and tilt certain angle by 10, and two pieces of arcs 11 are hinged with support 10 can any adjusting pole 10
With the angle of two pieces of arcs 11 to adapt to the needs in well site, two pole lower ends of support 10 divide connection to have adjusting screw 13,
The height of adjusting pole 10 is carried out to adapt to different well sites demand, the height of adjusting pole 10, it is ensured that two by adjusting screw 13
The uniform force of leg, the lower end of support 10 is provided with stop nut 12.By using after the height of adjusting screw 13 adjusting pole 10
Stop nut 12 is fixed, and prevents support 10 from rotating and causes whole device location to change, and ensures when using first
Uniform force, reduces impact as far as possible, and the other end of two pieces of arcs 11 is fixedly connected with operation frame 2, the side of operation frame 2 bottom surface
Being fixed with pipe 15, operation frame 2 is arranged with pipe 15 vertical direction, the pipe 15 on operation frame 2 and rotating base 1 grafting,
Installing rotating base 1 on well head, the side of the upper surface of rotating base 1 is fixed with and intubates 16, and pipe 15 is inserted in intubating 16
Realize connecting.Pipe 15 can rotate intubating 16, moves implement by the rotational band of pipe 15 and rotates and adjust carbon fiber
The position of sucker rod 17 entrance, owing to well head operating mode is complicated, equipment is more, needs inching carbon fibre pumping rod 17 sometimes
The position of entrance, it is ensured that carbon fibre pumping rod 17 is consistent with the axis of well head, realizes, by pipe 15 by rotating pipe 15
Adjust installation direction, it is ensured that the incoming direction of sucker rod does not tilts.
The radian of arc 11 is 90 degree, and arc 11 is level near that end face of well head, just can
Ensureing the vertical lower going-into-well mouth of carbon fibre pumping rod 17, the radius of arc 11 is 1.6 meters, because the revolution of carbon fibre pumping rod 17
Minimum 1.5 meters of radius, the radius of arc 11 is 1.6 meters disclosure satisfy that the requirement of carbon fibre pumping rod 17 radius of gyration, makes
Carbon fibre pumping rod 17 will not occur plastic deformation during operation curves, it is ensured that carbon fibre pumping rod 17 stands intact.Cause
For carbon fibre pumping rod 17 once there is plastic deformation, whole sucker rod is not the most straight, and the sucker rod of hundreds of meter just cancels
Need operations again.
The two ends of rotary shaft 8 are separately installed with bearing 4, and bearing 4 lays respectively at the outside of two pieces of arcs 11, outside bearing 4
Be provided with bearing cap 3 bearing 4 is protected, bearing 4 is additionally provided with priming cup 5 carry out oiling ensure bearing 4 lubricate.
The material of rubber sleeve 9 is politef.Carbon fibre pumping rod 17 ensures that carbon fiber is taken out when running on rubber sleeve 9
The surface of beam hanger 17 is not by any abrasion, and additionally politef material is ageing-resistant, good springiness.
During use, carbon fibre pumping rod 17 is wrapped on capstan winch 14, and capstan winch 14 diameter 3 meters, on capstan winch 14, the fiber of carbon is taken out
Beam hanger extends to rotary shaft 8, capstan winch 14 motor be rotated by make carbon fibre pumping rod 17 enter under moving ahead along rotary shaft 8
In well, capstan winch 14 output lead speed is 18.84 ms/min.
