Description

Technical Field

[0001] The present invention relates to the technical field of centralizers, and more specifically, to a rigid ball casing centralizer and its processing and forming device. Background Art

[0002] A centralizer, also known as a stabilizer, is a tool for stabilizing downhole drill strings and preventing deviation. It is connected to a section of drill pipe string near the large-diameter drill tool and is used to stabilize the drilling direction. It is an important tool for preventing well deviation in oil, natural gas, and geological exploration drilling projects. The centralizer can straighten the sucker rod, reduce the contact between the pipe and the rod, and avoid the mutual wear between the production tubing and the tubing. The uniform wear of the centralizer replaces the eccentric wear of the pipe and rod, and avoids pitting corrosion that causes tubing leakage. The centralizer can reduce the vibration load of the sucker rod in the wellbore, weaken the bending of the sucker rod, improve eccentric wear, and extend the service life of the pipe and rod. To increase the service life of the centralizer, reduce the number of well repairs, and extend the production cycle of the oil well, the selection of the centralizer material is particularly important.

[0003] The ball-type centralizer adopts a ball structure, which can reduce friction and torque during use and avoid the risks of downhole fracture and jamming. The current structural design of the ball-type centralizer is single. Most of them are installed with balls after casting and milling. Currently, the general ball installation method is by knocking, which is likely to damage the outer shape structure of the ball, resulting in a decline in the guiding effect. Moreover, after the ball wears, it is generally impossible to replace it, and only the entire centralizer can be replaced, resulting in a high use cost. Summary of the Invention

On the upper end face of the fifth bracket 61, there is an installation frame 611 fixedly connected. Above the fifth bracket 61, there is a third air cylinder 62.

[0055] Please refer to Figures 11 to 14 As shown, Embodiment 2 of the present invention provides a rigid ball sleeve centralizer. The centralizer 7 includes an annular outer shell 71. On the outer side of the annular outer shell 71, there is an axially arranged mounting groove 72. At the bottom end of the mounting groove 72, there is a sliding positioning groove 721. At the top end of the mounting groove 72, there is a threaded mounting hole 722.

[0056] Inside the installation grooves 72, detachable ball frames 73 are provided. On the ball frames 73, guiding balls 731 are arranged in an array. At the lower end of the ball frame 73, there is an insertion strip 732. At the top end of the ball frame 73, there is a pre-threaded groove 733. Inside the pre-threaded groove 733, there is a fastener 734 that is in threaded fit. The ball frame 73 is horizontally inserted into the installation groove 72. The insertion strip 732 is in sliding fit with the sliding positioning groove 721. After the ball frame 73 is completely pushed into the installation groove 72, the pre-threaded groove 733 is concentric with the threaded installation hole 722. By rotating the fastener 734 and inserting it into the threaded installation hole 722, the ball frame 73 and the annular housing 71 are fixedly connected.

[0057] Working principle:

[0058] During use, according to the diameter of the annular housing 71, the position of the installation head 69 is adjusted. The lead screw 67 is started to drive the threaded slider 672 to move up and down, thereby pushing the adjusting block 68 and the installation head 69 to move. After the installation head 69 reaches the specified position, the lead screw 67 stops rotating;

[0059] The first air cylinder 13 pulls the second bracket 12 to the lowest point. The second motor 55 is started 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 be inclined outward at an angle between 45° and 60°, which is convenient for the worker to place the annular housing 71. The bottom end of the annular housing 71 contacts the positioning block 545. The third motor 542 is started to drive the gear 544 and the driving disc 543 to rotate, thereby pulling the positioning block 545 to expand the diameter. After the auxiliary ball at the front end of the movable block 547 contacts the inner wall of the bottom ring of the annular housing 71, it starts to retreat and squeezes the elastic telescopic rod 546 to contract. When the elastic telescopic rod 546 contracts to the shortest value, the third motor 542 stops. At this time, the annular housing 71 can only rotate horizontally;

[0060] Then the bottom plate 51 rotates in reverse and returns to its original position. When the bottom plate 51 is horizontal with the second bracket 12, it stops. The second bracket 12 rises to the highest point. Then the third air cylinder 62 pulls the first electric slide 34 and the driving wheel 35 to the highest point. At this time, the driving wheel 35 is at the same height as the bottom ring of the annular housing 71. The first electric slide 34 drives the driving wheel 35 to contact the outer side of the bottom ring of the annular housing 71. The second electric slide 4 drives the linear displacement sensor 41 to move forward. The measuring ball 42 moves forward to contact and squeeze the outer side of the middle ring of the annular housing 71. The linear displacement sensor 41 records the displacement. The driving wheel 35 drives the annular housing 71 to rotate. When the measuring ball 42 enters the first group of installation grooves 72, the measuring ball 42 pops out and moves forward. The linear displacement sensor 41 sends an electrical signal to the PLC control system. The positioning of the annular housing 71 is completed. The driving wheel 35 stops. The second electric slide 4 drives the linear displacement sensor 41 to retreat and leave;

[0061] The manipulator 2 grabs the ball bearing housing 73 and inserts the ball bearing housing 73 into the second set of mounting grooves 72. Then, the driving wheel 35 drives the annular housing 71 to rotate 90° in sequence. The manipulator 2 inserts the ball bearing housing 73 into the third set of mounting grooves 72, the fourth set of mounting grooves 72, and the first set of mounting grooves 72 in sequence. Then, the third cylinder 62 pushes the fifth bracket 61 downward, and the mounting head 69 fastens 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, so as to rotate and insert the fastener 734 into the threaded mounting hole 722, thereby fixedly connecting the ball bearing housing 73 and the annular housing 71. The aligner 7 is assembled. Then, the driving wheel 35 retreats and leaves. The second bracket 12, the clamping assembly 5, and the aligner 7 descend to the lowest point. The bottom plate 51 and the positioning module 54 rotate and tilt, and the positioning block 545 retracts. An operator takes away the aligner 7;

[0062] Repeat the above operations to perform the subsequent assembly work of the aligner 7.
