Description
The present invention relates to the pumping well sucker-rod string rotation technique that a kind of oil field down-hole oil extraction rod-pumped well is used.
It is at a kind of manual or mechanical device of well head floor mounted that present down-hole, oil field oil extraction rod-pumped well often adopts the rod string spinning solution, regularly drive the tubing string rotation that makes in the underground equipment by operating personnel's turning handle or by oil pumper, thereby the relative oil pipe of rod string rotates, this method that rotates to an angle at an upper portion thereof, because wellhead assembly complexity, exist bad leakage of oil of sealing and rod collar and produce problems such as eccentric wear, therefore, fail to widely apply aborning.
At above-mentioned problems of the prior art, the object of the present invention is to provide and a kind ofly have only " pumping well sucker-rod string rotation technique " that underground equipment do not have the well head ground installation it has solved problems such as sealing is bad, leakage of oil, the easy eccentric wear of rod collar effectively, thereby improved the application life of sucker rod, remarkable in economical benefits.
The present invention is achieved in that the ground oil pumper offers oil pumping system power, so that oil pump plunger piston is reciprocating.When upstroke, oil pumping polish rod 1 moves upward, travelling valve ball 9 is closed, standing valve ball 10 is opened, at this moment fluid column weight acts on the oil pump plunger piston 8, be subjected to tension at the two ends of fluid column action of gravity lower sucker rod circulator 6 and on producing, following two connectors (circulator cam body, circulator transfer axle) elongates motion relatively, wherein the end component that make transfer axle move in the other end makes the cyclic track of closed type of cam body component, dial on the transfer axle of adopted formula (or tooth cassette) circulator 6 and be installed with pin, because the restriction of track, its shift fork angle of in axially-movable, pivoting, this turning moment drives oil pump plunger piston on the one hand and turns clockwise, and rod string is rotated counterclockwise between sucker rod anti-dropping device 2 that drive simultaneously can be pivoted and the rod rotor 6.When down stroke, oil pumping polish rod 1 moves downward, travelling valve ball 9 is opened, standing valve ball 10 is closed, act on fluid column weight disappearance on the oil pump plunger piston 8, oil pump plunger piston 8 is subjected to resistance when moving downward, then rod string gravity is to pressing down, the two ends of circulator 6 are under pressure and produce, the two connectors motion of shortening relatively down, wherein the end component that make transfer axle move in the other end makes the cyclic track of closed type of cam body component, because the restriction of track, its shift fork angle of in axially-movable, pivoting, this turning moment drives oil pump plunger piston on the one hand and turns clockwise, and rod string is rotated counterclockwise between sucker rod anti-dropping device 2 that drive simultaneously can be pivoted and the rod rotor 6.Like this, in the upper and lower stroke reciprocating motion of oil pumper process, the rod string between sucker rod anti-dropping device 2 and the rod rotor 6 just produces the batch (-type) rotation.The rod string whirligig is mainly by oil pumping polish rod 1, sucker rod anti-dropping device 2, sucker rod 3, oil pipe 4, sleeve pipe 5, rod rotor 6, oil well pump pump barrel 7, oil pump plunger piston 8, travelling valve ball 9, standing valve ball 10, sucker rod eccentrically worn preventor 12, rod collar 13 is formed.It is following or from nearest place, oil pump plunger piston top that the circulator 6 of this device is installed in the neutral point of rod string, and the top that sucker rod anti-dropping device 2 is installed in circulator 6 is promptly at the top of L1 (the rod string section that will rotate).The cyclic track that has closed type in the cam body of circulator, the transfer axle of circulator moves in the track of circulator cam body, is installed with pin on the axle of transfer axle, and pin makes transfer be drawn into the row rotation in reciprocating motion.The rotation component are driving links in conventional convex body, and the component in the linear reciprocating motion are Passive part, otherwise but in this device.
The present invention is compared with prior art: because it is simple in structure to have adopted circulator, anti-dropping device to have among the present invention, and dependable performance, wear-resisting, high temperature resistant; Owing to adopted eccentrically worn preventor to make oil pump plunger piston rotation change uniform wear, can improve sucker rod, box cupling and oil pump plunger piston application life, remarkable in economical benefits.

Below in conjunction with accompanying drawing several embodiment are described:
Embodiment 1
The present invention as shown in Figure 1 and Figure 2, by oil pumping polish rod 1 and sucker rod 3 screwed connections, sucker rod anti-dropping device 2 and sucker rod 3, sucker rod 3 respectively with rod rotor 6, oil pump plunger piston 8,12 screwed connections of sucker rod deflection preventer, rod collar 13 respectively with sucker rod anti-dropping device 2, sucker rod eccentrically worn preventor 12, rod rotor 6 screwed connections, be connected with oil pump plunger piston 8 in the bottom, then pack into oil pipe 4 and oil well pump pump barrel 7 reinstalls in the sleeve pipe 5, then forms the rod string whirligig.
Embodiment 2:
Feature of the present invention also is to use the technology of rod string whirligig: the ground oil pumper offers on the rod string whirligig, down stroke moves back and forth: when upstroke, oil pumping polish rod 1 moves upward, travelling valve ball 9 is closed, standing valve ball 10 is opened, fluid column weight acts on the oil pump plunger piston 8, be subjected to pulling force at the two ends of fluid column action of gravity lower sucker rod circulator 6 and on producing, two connectors elongate motion relatively down, wherein the end component that make transfer axle move in the other end makes the cyclic track of cam body component closed type, be installed with pin on the transfer axle of shift fork or tooth cassette circulator 6, because the restriction of track, its shift fork angle of in axially-movable, pivoting, this revolving force turns clockwise apart from driving oil pump plunger piston 8 on the one hand, and rod string is rotated counterclockwise between sucker rod anti-dropping device 2 that drive simultaneously can be pivoted and the rod rotor 6; When down stroke, oil pumping polish rod 1 moves downward, travelling valve ball 9 is opened, standing valve ball 10 is closed, act on fluid column weight disappearance on the oil pump plunger piston 8, oil pump plunger piston 8 is subjected to resistance when moving downward, then rod string gravity is to pressing down the two ends pressurized that makes circulator 6, and on producing, the two connectors motion of shortening relatively down, wherein an end makes the component of transfer axle, in making the cyclic track of cam body component closed type, the other end moves, because the restriction of track, its shift fork angle of pivoting in axially-movable, this turning moment drives oil pump plunger piston 8 and turns clockwise, and drives the sucker rod anti-dropping device 2 that can pivot and the rod string between the rod rotor 6 simultaneously and is rotated counterclockwise.Like this, in the upper and lower stroke reciprocating motion of oil pumper process, the rod string between sucker rod anti-dropping device 2 and the rod rotor 6 just produces step continuous rotation;
Embodiment 3:
Feature of the present invention also is: rod rotor 6 is installed in below the rod string neutral point or from nearest place, oil pump plunger piston 8 tops, and the use of the cam body in this circulator is that normal protruding turning down used.In normal cam body, the rotation component are driving link, and the component in the linear reciprocating motion are Passive part; In cam body of the present invention, driving link is the component of linear reciprocating motion, i.e. the transfer of circulator is taken out, and Passive part is the rotation component, and promptly the protruding of circulator turned.
