The present invention relates to the special instrument in down-hole that a kind of oil field machinery oil uses, is the underwell energy reservation and saving device for beam-pumping unit that is used for the energy-conservation usefulness of oil pumping machine oil pumping process.
Two, background technology
At present, the oil pump energy-saving device all is mounted on the oil pumper on ground, and energy-saving effect is not too obvious.Also there is not at present to find to be arranged on the interior energy saver of pit shaft.
Three, summary of the invention
The purpose of this invention is to provide a kind of underwell energy reservation and saving device for beam-pumping unit, the descending gravitional force of sucker rod is transformed into the potential energy of the built-in spring of down-hole energy reservation and saving device, when upstroke, again the potential energy of spring is discharged and be converted into the up kinetic energy of sucker rod, thereby solve the power consumption problem that reduces oil pumping motor.
Technical scheme of the present invention realizes in the following manner:
The present invention is by becoming the snapping head, the boll-weevil hanger joint, adaptor, spring strut, last energy-stored spring, connecting ring, following energy-stored spring, spring retainer and oil connection are formed, it is characterized in that rod-pumped well down-hole accumulator is made as cylindrical shape, its upper end is provided with the boll-weevil hanger joint, its lower end is provided with oil connection, be threaded with spring strut, be provided with by preface from top to bottom in it and become the snapping head, adaptor, last energy-stored spring, connecting ring, following energy-stored spring and spring retainer, becoming the snapping head is pressed on the adaptor, adaptor is pressed on the energy-stored spring, last energy-stored spring is pressed on the connecting ring, connecting ring is pressed in down on the energy-stored spring, following energy-stored spring is sitting on the spring retainer, and spring retainer is sitting on the oil connection; The boll-weevil hanger joint is threaded with the well head boll-weevil hanger, and oil connection is connected with tubing round thread; Become snapping head top and be threaded with polished rod, the bottom is threaded with sucker rod.
Change snapping head is made as cylindrical, and top is provided with the polished rod nipple, and the bottom is provided with the sucker rod nipple, and the middle part is provided with sleeve, and is welded with support between the change snapping head, and sleeve diameter is greater than the adaptor internal diameter.
Connecting ring is made as T shape ring, and is vertical with spring strut, between be made as movingly.
Spring retainer is made as cylindrical, and its external diameter is less than the spring strut internal diameter.
The internal diameter of oil connection is less than the external diameter of spring retainer.
The present invention and prior art are through having the following advantages:
1, energy storage capacity is big, according to the concrete condition of rod-pumped well several accumulators of can connecting.
2, accumulator is installed near well head, and spring releases energy directly to discharge and gives polished rod, can not cause rod sag, and the energy storage loss is little.
3, power savings is remarkable, and a bite well can be saved 80KW in one day.
