Abstract
The utility model relates to a pipe string scrubber for water injection well in oilfields, which can remove scale deposits on wall of water injection pipe. Previously, the methods for removing scale deposits on wall of water injection pipe are time consuming and tiresome. The utility model comprises a sleeve (1) and steel brushes (2) arranged inside the sleeve, wherein every two steel brushes (2) positioned side by side make up a group, a spring (6) is arranged between two steel brushes (2) below a shaft (4), a cam (3) arranged inside the sleeve is positioned above the steel brushes (2), and on the cam (3), a cam opening baffle (3-1) and a steel brush opening baffle (3-2) positioned in a right angle with the cam opening baffle (3-1) are arranged. This utility model has the advantages of simple structure and convinence in operation. By using the scrubber to remove scale deposits of water injection wells, time, manpower and material are saved and hence the operation cost is saved and the working efficiency is greatly enhanced, so the scubeer is in favor of being popularized and applied.
Description
Technical field: the utility model relates to the device of cleaning with water that can remove water filling tube wall incrustation scale that uses on a kind of oil field.
Background technology: the fouling of the water injection well borehole wall, influence the separate water injection well test, because the borehole wall has incrustation scale, when going into the well, tester is easy to dirt is bumped, cause water nozzle to stop up, water injection well pressure is risen, the water yield descends, so can't test allotment work normally, therefore, need cleaning tube wall incrustation scale.The method of in the past removing incrustation scale is oil pipe all to be tripped out more renew tubing string, do like this take a lot of work, effort, time-consuming, need pay a large amount of operating costs simultaneously.
The utility model content: the purpose of this utility model is to provide a kind of device of cleaning with water that tubing string just can scale removal that need not move, it comprises sleeve 1, be arranged on the steel brush 2 in the sleeve 1, per two steel brushes that are set up in parallel 2 are one group, each steel brush 2 all is connected with sleeve 1 by axle 4, be provided with spring 6 between two steel brushes 2 below the axle 4, on the sidewall of sleeve 1, be provided with the hole 1-1 that adapts with steel brush 2 structures, in sleeve 1, also be provided with cam 3, cam 3 is arranged on the top of steel brush 2 and is connected with sleeve 1 by axle 5, described cam 3 is provided with cam and opens baffle plate 3-1 and open the baffle plate 3-1 steel brush that is provided with that meets at right angles with cam and open baffle plate 3-2, described cam is opened the outside that sleeve 1 is stretched out in the termination of baffle plate 3-1, the lower end that steel brush is opened baffle plate 3-2 is arranged on the place, centre position of two steel brush 2 upper ends, on cam 3, also be provided with return spring 3-3, the end of return spring 3-3 is fixed on cam and opens on the baffle plate 3-1, and the other end of return spring 3-3 is fixed on the other end of opening the relative cam of baffle plate 3-1 3 with cam.The utility model is simple in structure, and is easy to operate, removes the water injection well incrustation scale by it and saves time and manpower and materials, saves operating cost, improved operating efficiency greatly, helps applying.
Description of drawings: Fig. 1 is a structural representation of the present utility model, Fig. 2 be the G of Fig. 1 to view,
Fig. 3 is the structural representation of cam 3, and Fig. 4 is the left view of Fig. 3, and Fig. 5 is the right view of Fig. 3,
Fig. 6 is the structural representation of steel brush 2, and Fig. 7 is the left view of Fig. 6, and Fig. 8 is the right view of Fig. 6.
The specific embodiment: present embodiment comprises sleeve 1, be arranged on the steel brush 2 in the sleeve 1, described steel brush 2 is by brush body 2-1, bristle 2-2 and gland 2-3 form, porose 2-1-1 on brush body 2-1, bristle 2-2 is arranged in the 2-1-1 of hole, gland 2-3 pushes down behind the bristle 2-2 by screw on brush body 2-1, per two steel brushes that are set up in parallel 2 are one group, each steel brush 2 all is connected with sleeve 1 by axle 4, be provided with spring 6 between two steel brushes 2 below the axle 4, on the sidewall of sleeve 1, be provided with the hole 1-1 that adapts with steel brush 2 structures, in sleeve 1, also be provided with cam 3, cam 3 is arranged on the top of steel brush 2 and is connected with sleeve 1 by axle 5, described cam 3 is provided with cam and opens baffle plate 3-1 and open the baffle plate 3-1 steel brush that is provided with that meets at right angles with cam and open baffle plate 3-2, described cam is opened the outside that sleeve 1 is stretched out in the termination of baffle plate 3-1, the lower end that steel brush is opened baffle plate 3-2 is arranged on the place, centre position of two steel brush 2 upper ends, on cam 3, also be provided with return spring 3-3, the end of return spring 3-3 is fixed on cam and opens on the baffle plate 3-1, and the other end of return spring 3-3 is fixed on the other end of opening the relative cam of baffle plate 3-1 3 with cam.
Operating principle of the present utility model is as follows: when needs to the scale removal of water injection well tube wall the time, at first will clean with water under the device in well, on cleaning device with water, carry in the process, cam on the cam 3 opens baffle plate 3-1 and the well wall collisions rotates, the drive steel brush is opened baffle plate 3-2 and is done equidirectional rotation when rotating, because steel brush is opened the place, centre position that the lower end of baffle plate 3-2 is arranged on two steel brush 2 upper ends, after opening baffle plate 3-2 rotation, will separate steel brush with the upper end of two steel brushes, the upper end of steel brush will be drawn close around axle 4 rotations under the effect of spring 6 owing to losing support like this, the lower end of steel brush can rotate to another direction simultaneously, bristle 2-2 on the steel brush after the rotation will promptly clean with water tube wall in steel brush travels longitudinally process with sleeve producing under the drive of brush body 2-1 outside the sleeve 1.
