Description

Technical Field

[0001] The invention relates to the technical field of centralizers, in particular to a rigid ball sleeve centralizer and a processing and forming device thereof. Background Art

[0002] A centralizer, also known as a stabilizer, is a tool that stabilizes downhole drilling tools and prevents deviation. It is connected to a section of the drill pipe column near the thick-diameter drill tool and is used to stabilize the drilling direction. It is an important tool for preventing well deviation changes in oil, natural gas and geological exploration drilling projects. The centralizer can centralize the sucker rod, reduce the contact between the pipe and the rod, and avoid mutual wear between the pumping pipe and the oil pipe. The uniform wear of the centralizer replaces the eccentric wear of the pipe and the rod, avoiding pitting corrosion that causes oil pipe leakage. The centralizer can reduce the vibration load of the sucker rod in the wellbore, reduce the bending of the sucker rod, improve eccentric wear, and extend the service life of the pipe and the rod. In order to increase the service life of the centralizer, reduce the number of oil well overhauls, and extend the production cycle of oil wells, the material selection of the centralizer is particularly important.

[0003] The ball-type centralizer adopts a ball structure, which can reduce friction and torque when in use, and avoid the risk of breakage and jamming underground. The current ball-type centralizer has a single structural design, and most of them are installed with balls after casting and milling. The current general ball installation method adopts a knocking method, which easily damages the external structure of the ball and causes a decrease in the guiding effect. In addition, the ball cannot be replaced after being worn, and the entire stabilizer can only be replaced, which has a high cost. Summary of the invention

[0057] Working principle:

[0058] When in use, the position of the mounting head 69 is adjusted according to the diameter of the annular housing 71, and the screw rod 67 is started to drive the threaded slider 672 to rise and fall, thereby pushing the adjustment block 68 and the mounting head 69 to move. When the mounting head 69 reaches the specified position, the screw rod 67 stops rotating;

[0059] The first cylinder 13 pulls the second bracket 12 down to the lowest point, the second motor 55 starts to drive the worm 52, the turbine 53, the bottom plate 51, and the positioning module 54 to rotate, and the positioning module 54 is rotated to tilt between 45° and 60° toward the outside, so that the workers can put in the annular shell 71 conveniently. The bottom end of the annular shell 71 contacts the positioning block 545, and the third motor 542 starts to drive the gear 544 and the drive disk 543 to rotate, thereby pulling the positioning block 545 to expand the diameter. The auxiliary ball at the front end of the movable block 547 contacts the inner wall of the circular ring at the bottom end of the annular shell 71 and then begins to retreat and squeeze the elastic telescopic rod 546 to contract. When the elastic telescopic rod 546 contracts to the shortest value, the third motor 542 stops, and the annular shell 71 can only rotate horizontally at this time.

[0060] Then the bottom plate 51 reverses and returns to its original position, the bottom plate 51 stops after being level with the second bracket 12, the second bracket 12 rises to the highest point, and then the third cylinder 62 pulls the first electric slide 34 and the driving wheel 35 to rise to the highest point. At this time, the driving wheel 35 is at the same height as the bottom ring of the annular shell 71, and the first electric slide 34 drives the driving wheel 35 to contact the outer side of the bottom ring of the annular shell 71, and the second electric slide 4 drives the linear displacement sensor 41 forward, and the measuring ball 42 moves forward to contact and squeeze the outer side of the middle ring of the annular shell 71, and the linear displacement sensor 41 records the displacement, and the driving wheel 35 drives the annular shell 71 to rotate, and when the measuring ball 42 enters the first group of mounting grooves 72, the measuring ball 42 pops up and moves forward, and the linear displacement sensor 41 sends an electrical signal to the PLC control system, and the positioning of the annular shell 71 is completed, the driving wheel 35 stops, and the second electric slide 4 drives the linear displacement sensor 41 to retreat and leave;

[0061] The manipulator 2 grabs the ball rack 73 and inserts the ball rack 73 into the second group of mounting grooves 72. Then the driving wheel 35 drives the annular shell 71 to rotate 90 degrees in sequence. The manipulator 2 inserts the ball rack 73 into the third group of mounting grooves 72, the fourth group of mounting grooves 72 and the first group of mounting grooves 72 in sequence. Then the third cylinder 62 pushes the fifth bracket 61 to descend. The mounting head 69 buckles the fastener 734. The fifth motor 63 starts to drive the large gear 64, the small gear 65, the telescopic universal joint 66 and the mounting head 69 to rotate, thereby rotating the fastener 734 and inserting it into the threaded mounting hole 722, thereby fixing the ball rack 73 and the annular shell 71. The centralizer 7 is assembled. Then the driving wheel 35 retreats and leaves. The second bracket 12, the clamping assembly 5 and the centralizer 7 descend to the lowest point. The bottom plate 51 and the positioning module 54 rotate and tilt, and the positioning block 545 retracts. The centralizer 7 is manually taken away.

[0062] Repeat the above operation to assemble the subsequent centralizer 7.
