The utility model has simple structure and convenient operation with strong impact force and good descaling effects, which can conduct one-time descaling during construction with obvious effects, thereby lowering the operating cost, saving the working time, and improving the work efficiency.
Description
Technical field: the utility model relates to a kind of device that water injection well on the oil field is carried out scale removal.
Background technology: at present, oil-field flooding tubing string scale formation is more and more serious, bring very big inconvenience to injection well testing, make under the tester less than the layer position that will test, even can't test, can only take operation now for scale removal and handle, but operating cost height, time are long, have reduced operating efficiency.
Utility model content: at water injection well tubing string fouling serious situation on the oil field, the utility model provides a kind of spiral water injection well side-pocket mandrel descaler that can make the quick de-sludging of water injection well tubing string, it comprises overcoat 1, the cylindrical shell that overcoat 1 communicates for two ends, also comprise the knife bar 2 that is arranged in the overcoat 1, knife bar 2 is cylindrical, the external surface of cylinder shape knife rod 2 is provided with helicla flute 2-1, have through hole 1-1 on the sidewall of described overcoat 1, the front end that has pin 5 to pass through hole 1-1 and pin 5 is arranged in the helicla flute 2-1 of knife bar 2, it also comprises cutter head 3, spring 4, cutter head 3 fixedly connected with the front end of knife bar 2 and the cross-sectional area of junction cutter head 3 greater than the cross-sectional area of overcoat 1, spring 4 is arranged on the rear end of knife bar 2 in the overcoat 1, is provided with connecting rod 6 in the rear end of spring 4.The utility model is simple in structure, be convenient to operation, and its impact force is strong, and features high scale-removing effect can disposable scale removal when construction, and effect is obvious, has reduced operating cost, has saved labour hour, has improved operating efficiency.
Description of drawings: Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the structural representation of overcoat 1, and Fig. 3 is the structural representation of cutter head and knife bar, and Fig. 4 is the structural representation of the specific embodiment two, and Fig. 5 is the A-A sectional drawing of Fig. 4.
The specific embodiment one: with reference to Fig. 1, Fig. 2, Fig. 3, present embodiment comprises overcoat 1, the cylindrical shell that overcoat 1 communicates for two ends, also comprise the knife bar 2 that is arranged in the overcoat 1, knife bar 2 is cylindrical, the external surface of cylinder shape knife rod 2 is provided with helicla flute 2-1, have through hole 1-1 on the sidewall of overcoat 1, the front end that has pin 5 to pass through hole 1-1 and pin 5 is arranged in the helicla flute 2-1 of knife bar 2, present embodiment helicla flute 2-1 is two groups that are crisscross arranged, be arranged on through hole 1-1 on overcoat 1 sidewall and be two and position over against, two pins 5 that pass through hole 1-1 are separately positioned in the groove of two helicla flute 2-1, pin 5 and overcoat 1 are by being threaded, it also comprises cutter head 3, spring 4, cutter head 3 is for having the cylinder of vertical blade, cutter head 3 fixedly connected with the front end of knife bar 2 and the cross-sectional area of junction cutter head 3 greater than the cross-sectional area of overcoat 1, spring 4 is arranged on the rear end of knife bar 2 in the overcoat 1, be provided with connecting rod 6 in the rear end of spring 4, described connecting rod 6 is by jackscrew 7 and overcoat 1 relative fixed, through hole 1-1 on overcoat 1 sidewall is at least two, through hole 1-1 in the present embodiment is two, when installing, to be inserted in the overcoat 1 with the affixed knife bar of cutter head, because the cross-sectional area of cutter head and knife bar junction is greater than the cross-sectional area of overcoat 1, so cutter head is stuck in the external end head place of overcoat 1, by pin 5 knife bar is fixed on and plays the effect of avoiding knife bar to deviate from overcoat in the overcoat 1, the spring of packing in the rear end of knife bar, withstand with connecting rod 6, connecting rod and overcoat 1 relative fixed had both been finished installation by jackscrew; When using, cutter head 3 is extend in the body that needs scale removal by connecting rod 6, meet dirty sheet when cutter head and produce resistance when being obstructed, pressuring spring, the reaction force that spring produces forward promotes knife bar forward, because two pins are separately positioned in two conveyor screws of knife bar, thereby, conveyor screw makes 3 rotations of knife bar rotation advancing drive cutter head so moving along pin, the position of two pins over against, promptly two pins are in the same cross section of knife bar, and they can make knife bar stressed evenly, steadily advance, cutter head 3 is provided with blade longitudinally, the dirty sheet that vertical blade cuts is in contact with it, thus reach the scale removal purpose.
The specific embodiment two: with reference to Fig. 4, Fig. 5, what present embodiment and the specific embodiment one were different is, cutter head 3 is for having the Rotary-table of vertical blade, Rotary-table be set to the microcephaly preceding, major part is connected with knife bar 2 in the back, and when dirty sheet was thicker, the microcephaly can enter in the chamber that thicker dirty sheet surrounds, make the blade at major part place can cut to more large-area dirty sheet, thereby improve scale removal efficient.
