Two, background technology
One of difficult problem that the oil well Operating Pressure need solve is to realize the inside shutoff of sucker-rod pumping completion tubular column.Because the restriction of standing valve, can't suppress the formation feed pathway after the whole oil well pump shutoff, the pumping pipe string method for blocking is to be provided with in the tubing string lower end to suppress sliding sleeve at present, the shortcoming of this method for blocking has: but 1. oil well pump must be with the whole tube pump of insert pump or standing valve pulling, and can not be effective with oil pumping, widely used common whole tube pump has dwindled the oil well pump range of choice, has reduced the oil pumping effect.2. need sliding sleeve is opened before the lower sucker rod post, be lowered to rod string then, also be with when making the lower sucker rod post and press construction, increased the job execution difficulty.
Three, summary of the invention
The objective of the invention is to overcome above technical deficiency, provide a kind of employing that the plugging device of the common whole tube pump pumping pipe string of bar is arranged, be implemented under the band pressure condition and be lowered to the sucker-rod pumping completion tubular column, and reduce the construction complexity, improve the reliability and the oil pumping effect of pumping pipe string.
Oil well Operating Pressure sucker-rod pumping completion tubular column plugging device of the present invention, comprise the adjusting mandrel, box cupling, top connection, upper piston, locking nut, the bump rod, oil pipe, lower contact, lower piston, screen casing, plug and oil well pump, it is characterized in that described oil well pump lower end and box cupling, top connection, box cupling, oil pipe, box cupling, lower contact, box cupling, screen casing is connected in turn with plug, described upper piston is fixed in the top connection by last shear pin, lower piston is fixed in the lower contact by following shear pin, described adjusting mandrel is installed in the upper piston, the oil well pump fixed valve ball is backed down in this adjusting mandrel upper end, this adjusting mandrel lower end is connected with the bump rod by locking nut, and described bump rod is in the oil pipe.
Wherein, described upper piston is a hollow-core construction, which is provided with internal thread, and excircle is provided with an outer step, and last shear pin is positioned under this outer step.Be provided with step in the described top connection, the outer step of described upper piston matches with step in this.Described adjusting mandrel upper end be interior concave spherical surface, regulates that the mandrel lower end is connected by screw thread or bearing pin with the bump rod or direct and clash into rod and make one.Described adjusting mandrel is provided with external screw thread, is meshed with the internal thread of upper piston.Described lower contact upper end is a back taper targeting port structure, and its targeting port bottom is provided with interior step, and the lower piston top places under this interior step.
The present invention has following advantage compared with prior art:
1, plugging device directly is connected the lower end of the whole tube pump pump housing, and is easy for installation.
2, upward pressure is born by the step on the upper and lower joint, the sealing load height, and downward pressure is born by upper and lower shear pin, suppresses the success rate height that forms oil inlet passage.
3, suppress the formation oil inlet passage after having descended rod string, be not with during the lower sucker rod post depress into, reduced difficulty of construction.
4, this method for blocking must improve oil well pump oil pumping effect with the shortcoming of insert pump or standing valve pulling pump but overcome prior art.
Four, description of drawings
Accompanying drawing is a kind of structural representation of the present invention.
Five, the specific embodiment
Consult accompanying drawing, a kind of oil well Operating Pressure sucker-rod pumping completion tubular column plugging device comprises and regulates mandrel 1, box cupling 2, top connection 4, upper piston 6, locking nut 7, bump rod 8, oil pipe 9, lower contact 10, lower piston 12, screen casing 13, plug 14 and oil well pump 18.Oil well pump 18 lower ends are connected in turn with box cupling 2, top connection 4, box cupling 2, oil pipe 9, box cupling 2, lower contact 10, box cupling 2, screen casing 13 and plug 14, upper piston 6 is fixed in the top connection by last shear pin 5, regulating mandrel 1 is installed in the upper piston 6, oil well pump fixed valve ball 19 is backed down in this adjusting mandrel 1 upper end, this adjusting mandrel 1 lower end is connected with bump rod 8 by locking nut 7, this bump rod is in the oil pipe 9, and lower piston 12 is fixed in the lower contact 10 by following shear pin 11.
Upper piston 6 is a hollow-core construction, which is provided with internal thread, and excircle is provided with an outer step 16, and last shear pin 5 is positioned under this step.Be provided with step 17 in the top connection 4, the outer step of upper piston matches with step in this.Regulating mandrel 1 upper end is interior concave spherical surface, and this adjustings mandrel 1 lower end is connected by screw thread or bearing pin with bump rod 8 or is direct and clash into rod and make one.Regulate mandrel 1 and be provided with external screw thread, be meshed with the internal thread of upper piston 6.Lower contact 10 upper ends are back taper targeting port structure, and its targeting port bottom is provided with interior step 15, and the lower piston top places under this interior step.On upper piston 6 and the lower piston 12 sealing ring 3 is installed.
