[0002] At present, in the water injection string, the feeder is generally used for the delivery operation. When the plug to be delivered is long and the slope of the injection well is large, the delivery operation cannot be successful, because there is no delivery device at present. The support device at the bottom end of the plug, when using a feeder to put a long plug into the eccentric hole of the working cylinder downhole, the bottom end of the plug will shrink radially inward under the action of gravity, and cannot be aligned with the eccentric hole. The main channel of the working cylinder passes through, and finally cannot be put into the partial hole of the working cylinder

Embodiment Construction
[0017] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0018] refer to figure 1 , figure 2 , image 3 and Figure 4 , the support structure for the dispenser according to the present invention includes an upper body 2, a lower body 13, a first cam 3, a first shaft 9, a second shaft 21, a support block 22, a third spring 23, a fishing arm 6. The throwing claw 10, the second spring 8, the long plug 20 and the rope cap 1; the side surface of the upper body 2 is provided with a first opening slot 24 and a first through hole, and the first cam 3 is located in the first opening slot 24. In the through hole, and the first cam 3 can rotate in the first through hole, the side of the first cam 3 is provided with a blocking claw 4, the blocking claw 4 extends out of the first through hole, and one end of the fishing arm 6 is in contact with the first through hole. The two inner walls of the first opening slot 24 are connected b...

The invention discloses a supporting structure for a delivery device. The supporting structure comprises an upper body, a lower body, a first cam, a first shaft, a second shaft, a supporting block, athird spring, a delivery and catch arm, a delivery and catch claw, a second spring, a long blanking plug and a rope socket. The supporting structure is installed on the delivery device, and the long blanking plug can be supported out of a notch of a first opening groove, so that the delivery device meets the demand of putting the long blanking plug into a partial hole of a work cylinder under thecondition of a highly-deviated well. After accidentally falling off a delivery head, the long blanking plug cannot be clamped in a gap between an oil pipe and a delivery and catch device and can fallinto a pocket of the delivery device, and the accident that the delivery device is clamped is avoided. Therefore, by means of the supporting structure, the delivery device can smoothly deliver the long blanking plug into the partial hole of the work cylinder under the condition of the highly-deviated well.
Description
technical field [0001] The invention relates to a support device, in particular to a support structure for a dispenser. Background technique [0002] At present, in the water injection pipe string, the injector is generally used for the delivery operation. When the delivered plug is long and the inclination of the water injection well is large, the delivery operation cannot be successful. The reason is that the current injector does not have The bottom end support device of the plug, when the long plug is put into the eccentric hole of the working cylinder with the feeder, the bottom end of the plug will shrink inward in the radial direction due to the action of gravity, and cannot be aligned with the eccentric hole, instead of The main passage of the working cylinder passes through, and finally cannot be put into the partial hole of the working cylinder. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings...
