In the second embodiment, the first embodiment of the method,
the spring 23 is made of 60Si2MnA steel;
the gap between the spring 23 and the sieve tube 11 can be adjusted;
the spring 23 is made of 60Si2MnA steel, the content of 60Si2MnA alloy elements is low, the hardenability is higher than that of 60Si2Mn, the toughness and the plasticity are also higher, the decarburization tendency is small, the tempering stability is good, the hot workability is good, and the cost is low; the strength, hardness, elasticity and hardenability of 60Si2MnA are all higher than those of No. 65 steel, so that when the spring 23 is applied to a process pipe column, the elastic property of the spring 23 is good, and further when the rotating shaft 21 drives the spring 23 to vibrate through the lantern ring 24, the efficiency of crushing impurities in the oil field around the sieve tube 11 by the spring 23 is improved, and the impurities in the oil field can be better prevented from being accumulated on the sieve tube 11;
furthermore, by adjusting the gap between the spring 23 and the screen pipe 11, when the gap between the spring 23 and the screen pipe 11 is small and the spring 23 contracts and extends up and down, the spring 23 is attached to the outer wall of the screen pipe 11, so that the inner ring steel wires of the spring 23 can scrape impurities inside the oil field adhered on the screen pipe 11, and when the spring 23 contracts, the gap between the steel wires on the spring 23 is gradually reduced, so that the spring 23 can crush the impurities positioned between the steel wires; and when the spring 23 contracts and extends, the spring 23 and the sieve pores on the sieve tube 11 move in a mutually staggered manner, so that the steel wires on the spring 23 can shear impurities on the sieve pores of the sieve tube 11, and the normal use of the sieve tube 11 is further ensured.
In the third embodiment, the first step is that,
the difference between the third embodiment and the second embodiment is that,
when the gap between the spring 23 and the sieve tube 11 is large, when the rotating shaft 21 rotates, the rotating shaft 21 pushes the lantern ring 24 to move up and down through the guide block 25, and because the gap between the spring 23 and the sieve tube 11 is large, when the spring 23 contracts and vibrates, the constraint effect of the sieve tube 11 on the inner diameter of the spring 23 is small, so that the stability of the spring 23 on the outer ring of the sieve tube 11 is reduced, when the spring 23 vibrates, the spring 23 can also swing in the horizontal direction on the basis of the up-and-down movement of the spring 23, and further when the spring 23 vibrates, solid impurity particles in oil fields around the sieve tube 11 are stirred, so that the sieve tube 11 is prevented from being blocked by the solid impurities in the oil fields;

through evenly having linked firmly arc 27 at lantern ring 24 up end, make the through-hole 28 seted up on the arc pole board, when axis of rotation 21 rotated, axis of rotation 21 promoted lantern ring 24 through guide block 25 and carried out the up-and-down motion, during lantern ring 24 up-and-down motion, lantern ring 24 promoted arc 27 and slides from top to bottom at the outer wall of screen pipe 11, when arc 27 slided from top to bottom, through-hole 28 on the arc 27 and the sieve mesh staggered movement on the screen pipe 11, if the impurity adhesion in the oil field appears when the outer lane wall of screen pipe 11, scrape from top to bottom through arc 27, can effectually make the solid-state impurity separation of screen pipe 11 outer lane wall adhesion, and then can improve the permeability of screen pipe 11, avoid screen pipe 11 to appear blockking up.
The lower side wall of the through hole 28 is fixedly connected with a projection 29, and the projection 29 extends into the through hole 28;
the convex blocks 29 are arranged in an arc shape, and the convex blocks 29 are inclined towards the inside of the sieve holes;
the convex block 29 is fixedly connected to the lower side wall of the through hole 28, so that the convex block 29 extends into the through hole 28, when the rotating shaft 21 rotates, the arc-shaped groove 22 above the rotating shaft 21 moves along with the rotating shaft 21, when the rotating shaft 21 rotates, the guide block 25 slides in the arc-shaped groove 22, and rotates along with the rotating shaft 21, the guide block 25 pushes the lantern ring 24 to move up and down, the lantern ring 24 drives the arc-shaped block to move up and down, when the arc-shaped block moves up and down, the convex block 29 on the inner wall of the through hole 28 moves up and down along with the arc-shaped block, and because the convex block 29 extends into the sieve hole on the sieve tube 11, when the arc-shaped plate 27 moves up and down, the convex block 29 stretches out and draws back in the sieve hole of the sieve tube 11, thereby avoiding the sieve hole on the sieve tube 11 from being blocked by solid impurities in the oil field, and further improving the permeability of the sieve tube 11; and through making the lug 29 for the arc setting, and make the lug 29 slope towards in the through-hole 28, make the lug 29 along with arc 27 up-and-down motion, the lug 29 can dredge the sieve mesh on the screen pipe 11, and then has further improved the permeability of screen pipe 11, improves the filter effect of screen pipe 11.
The specific working process is as follows:
the pipe body 1, the screw rod 12, the sieve pipe 11, the divider 3 and the pneumatic actuator which are related in the application are made of the same materials as those used in the prior art, and when the application is used in different environments, the structural units related in the application are the same as those of the process pipe column in the prior art, and the specifications of the process pipe column can be adjusted and produced according to the change of the environments; the screw 12 of the present application is different from the screw of the prior art in that the lower end of the screw 12 of the present application is made of a magnetic material;
furthermore, the pipe body 1 is installed in an oil well, the sieve pipe 11 at the lower end of the pipe body 1 extends into an oil layer in the oil well, then the pneumatic actuator is started, when the pneumatic actuator operates, the pneumatic actuator controls the screw rod 12 to rotate, when the screw rod 12 rotates, the spiral groove on the outer ring of the screw rod 12 conveys oil in the oil layer, the oil in the oil layer is conveyed to the ground surface through the pipe body 1, when the oil in the oil layer enters the pipe body 1, the oil can firstly pass through the sieve pipe 11 and then be filtered through the sieve pipe 11, so that the impurity particles contained in the oil layer are blocked outside the pipe body 1, however, in the process of conveying oil upwards, the force generated by the sieve tube 11 is a suction force, and when the sieve tube 11 sucks substances in the oil layer, impurities are inevitably adsorbed on the outer ring of the sieve tube 11, so that the sieve tube 11 is blocked;
when the screw 12 is rotated, the lower end of the screw 12 is made of magnetic material, the rotating shaft 21 is also made of magnetic material, so that when the screw 12 is rotated, the screw 12 and the rotary shaft 21 are attracted to each other, thereby rotating the rotary shaft 21, and when the rotary shaft 21 rotates, the guide block 25 moves in the arc-shaped groove 22 on the rotary shaft 21, so that the guide block 25 pushes the collar 24 to move up and down on the outer ring of the screen pipe 11, the collar 24 pushes the spring 23 to contract and extend up and down on the outer ring of the screen pipe 11, when the springs 23 are contracted and extended, the steel wires between the springs 23 crush the oil layer impurities around the lantern ring 24, and the spring 23 generates vibration when contracting and extending, which can make the impurities around the sieve tube 11 open, thereby reducing the probability of accumulation of oil layer impurities on the sieve tube 11 to a certain extent and further improving the service efficiency of the process pipe column.
