Accompanying drawing explanation
The structural representation of the sleeve scale remover that Fig. 1 provides for the utility model embodiment.
The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
Please refer to Fig. 1, the utility model embodiment provides a kind of sleeve scale remover, for the fouling except in Decanning (not shown).This sleeve scale remover comprises upper body tubing string 1, lower body tubing string 2 and at least three cutting pinions 3.Lower body tubing string 2 is provided with sliding tray 21 along axis, and upper body tubing string 1 is slidably mounted in sliding tray 21 and can drives lower body tubing string 2 to move together.The outer peripheral face that lower body tubing string 2 closes on sliding tray 21 is provided with the groove 22 of an annular.Cutting pinion 3 is arranged on lower body tubing string 2 evenly distributedly along the axis of lower body tubing string 2, and is contained in groove 22.The axis of each cutting pinion 3 is vertical with the axis of lower body tubing string 2, and these are cut gear 3 and are greater than the external diameter of lower body tubing string 2 and are not more than the internal diameter of sleeve pipe at the circumscribed diameter of the axis projection of lower body tubing string 2.
Under sleeve scale remover of the present utility model to after the fouling section of sleeve pipe, handling sleeve pipe repeatedly, after sleeve scale remover of the present utility model is hampered, namely sleeve structure herein causes internal diameter too small.Now need to raise and decentralize repeatedly fast upper body tubing string 1, lower body tubing string 2 is along with 1 motion of upper body tubing string, cutting pinion 3 rotates around axis separately because the resistance with internal surface of sleeve pipe makes cutting pinion 3, internal surface of sleeve pipe is cut repeatedly, to reach the object of removing the fouling on internal surface of sleeve pipe.The utility model is by raising and decentralizing repeatedly fast upper body tubing string 1, cutting pinion 3 is rotated under the effect of the resistance with internal surface of sleeve pipe, thereby 3 pairs of internal surface of sleeve pipe of cutting pinion cut repeatedly, can reach the object of removing the fouling on internal surface of sleeve pipe, simple in structure, cost is low.
Particularly, in the present embodiment, lower body tubing string 2 is fixed on by an alignment pin 31 in the axis place of each cutting pinion 3, and the periphery of each cutting pinion 3 is evenly provided with a plurality of teeth 33.Each cutting pinion 3 rotates around alignment pin 31, thereby drives 33 pairs of internal surface of sleeve pipe of tooth repeatedly to cut, to reach the object of removing the fouling on internal surface of sleeve pipe.
Particularly, in the present embodiment, sliding tray 21 is step trough, and it comprises that one runs through lower body tubing string 2 towards the through hole section (not label) of the first end of upper body tubing string 1 and the set section 211 being communicated with through hole section.Wherein, the size of set section 211 is greater than the size of through hole section, and set section 211 is formed with a stop surface 213 with the junction of through hole section.Upper body tubing string 1 comprises and connects shell of column 11 and the fixing backstop 13 with connecting shell of column 11.Connect shell of column 11 and slide through through hole section and along through hole section, backstop 13 is placed in set section 211 and in set section 211, slides into backstop in the diapire of stop surface 213 or set section 211.Like this, while raising and decentralizing repeatedly upper body tubing string 1 fast, connect shell of column 11 and slide along through hole section, and drive backstop 13 in set section 211, to slide into backstop in the diapire of stop surface 213 or set section 211.By backstop 13 and the interaction of the diapire of stop surface 213 or set section 211, drive lower body tubing string 2 with 1 motion of upper body tubing string, final drive cuts that gear 3 rotates and the fouling of removing internal surface of sleeve pipe.Preferably, in the present embodiment, upper body tubing string 1 also comprises the joint 15 that connects shell of column 11, and this joint 15 is for being fixedly connected with the handling device (not shown) for handling upper body tubing string 1.
Particularly, in the present embodiment, on lower body tubing string 2, be also provided with the pod apertures 25 being communicated with set section 211.
Particularly, in the present embodiment, lower body tubing string 2 comprises a tapered guiding point 27 away from the end tail of one end of sliding tray 21.By this guiding point 27 so that guide this sleeve scale remover of the present utility model and move up and down in sleeve pipe.
Concrete, as preferred embodiment, on the upper body tubing string 1 of sleeve scale remover of the present utility model, jar (not shown) is also installed.When on carry or transfer upper body tubing string 1 while running into jam, can utilize jar unfreezing, what make that sleeve scale remover of the present utility model uses is more smooth and easy.
The utility model also provides a kind of well repairing device, and this well repairing device comprises above-mentioned sleeve scale remover.Apparently, the well repairing device that has an above-mentioned sleeve scale remover also has advantage and the effect of above-mentioned sleeve scale remover certainly.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
