Fig. 2 is the partial enlarged drawing of the push-pull device at fixed 5 of the electrodynamic type centralizer among Fig. 1.
The specific embodiment
For making the contents such as the above-mentioned purpose of the utility model, feature and advantage can be more obviously understandable, the hereinafter spy enumerates preferred embodiment, and cooperates appended graphicly, elaborates as follows.
As shown in Figure 1, Fig. 1 is the structure chart of the electrodynamic type centralizer of the utility model.This electrodynamic type centralizer comprises control circuit 1, high temperature direct current generator 2, ball-screw screw assembly 3, travel control system 4, push-pull device at fixed 5, adapter sleeve 6 and mechanical type centralizer 7 compositions.High temperature direct current generator 2 connects ball-screw screw assembly 3, and ball-screw screw assembly 3 connects push-pull device at fixed 5, and push-pull device at fixed 5 is connected with mechanical type centralizer 7 through adapter sleeve 6; High temperature direct current generator 2 links to each other with travel control system 4 again.
Control circuit 1 starts high temperature direct current generator 2 and rotates under the enabled instruction of ground system, and the ball-screw that drives ball-screw screw assembly 3 rotates; And make ball-screw screw assembly 3 drive push-pull device at fixed 5 moving linearlies, when arriving certain stroke, travel control system 4 signals to control circuit 1; Control high temperature direct current generator 2 stops operating; Ground system sends the counter-rotating instruction for control circuit 1, and high-temperature electric machine 2 counter-rotatings realize the counter motion of push-pull device at fixed 5.Control circuit 1 is used to receive surface instruction and control motor positive and inverse; High temperature direct current generator 2 is used to drive leading screw and rotates; Ball-screw screw assembly 3 is used for rotatablely moving of leading screw become rectilinear motion; Travel control system 4 is used for the signal control motor rotating to circuit 1 being provided, and push-pull device at fixed 5 is used for push-and-pull adapter sleeve 6, makes the support arm of mechanical type centralizer 7 shrink or open.
As shown in Figure 2, Fig. 2 is the partial enlarged drawing of the push-pull device at fixed 5 of the electrodynamic type centralizer among Fig. 1.Push-pull device at fixed 5 is made up of pull bar 8, push-and-pull piece fixed cover 9, push-and-pull piece 10, push-and-pull cover 11, interstage sleeve nut 12 and combined cover 13.Fixing push-and-pull fixed cover 9 on the pull bar 8 of push-pull device at fixed 5, this push-and-pull fixed cover 9 is that a cylindrical has cannelure, and the fixedly screw of push-and-pull piece 10 is arranged at the bottom of cannelure.Push-pull device at fixed 5 is to realize through the push-and-pull piece 10 that is fixed on the push-and-pull fixed cover 9, and push-and-pull piece 10 is that an internal diameter is consistent with push-and-pull fixed cover 9 bottom lands, and external diameter overlaps the structure that the consistent annulus of 11 cylindricals is cut into push-and-pull.Push-and-pull cover 11 is on the basis of the spring housing of former mechanical centralizer, to improve to form, and the one of which end is a spring housing, and the other end is connected with push-and-pull piece 10, and its this end has the slotted eye that matches with push-and-pull piece 10.
When this electrodynamic type centralizer through internal diameter diminish oil well pipe the time; Rotate through the leading screw that control circuit 1 control high temperature direct current generator 2 drives in the ball-screw screw assembly 3 by ground; Screw in the ball-screw screw assembly 3 then drives pull bar 8 and does upwards axially-movable; Spur push-and-pulls cover 11 by push-and-pull fixed cover 9 and push-and-pull piece 10 again, and then pulling interstage sleeve nut 12 and combined cover 13, pressure support arm 15 compresses springs 14 and shrinks; After being retracted to corresponding size, can be smoothly through the tubing string after diminishing.When the tubing string internal diameter becomes big; 2 reverse rotations of control high temperature direct current generator, the screw in the ball-screw screw assembly 3 drives pull bar 8 and does downward axially-movable, promotes push-and-pull cover 11 by push-and-pull fixed cover 9 and push-and-pull piece 10 again; And then promotion interstage sleeve nut 12 and combined cover 13; Spring 14 is loosened and support arm 15 is released, it is big to the tubing string internal diameter size to rise, and satisfies the requirement of setting upright.
