DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5As shown, a novel oilfield physical plugging removal and injection and oil displacement device comprises a main body 1 and an active adaptation device 2; the active adaptation device 2 is installed with a servo motor 21, a ball screw 22 is fixedly installed at the output end of the servo motor 21, a ball nut 23 is passed through and threadedly connected to one side of the ball screw 22, a first gear 24 is fixedly installed on one side of the ball screw 22, a second gear 25 is transmission-connected to one side of the first gear 24, a linkage rod 26 is fixedly installed at the bottom of the second gear 25, a third gear 35 is fixedly installed at the other end of the linkage rod 26, a fourth gear 36 is transmission-connected to one side of the third gear 35, and another ball screw 22 is fixedly installed on one side of the fourth gear 36;

[0024] During operation, the ball screw 22 is rotated by driving the servo motor 21. The ball screw 22 cooperates with the ball nut 23 to realize the linear displacement of the ball nut 23. At the same time, the first gear 24 transmits the second gear 25, the linkage rod 26 and the third gear 35 in sequence. The cooperation between the third gear 35 and the fourth gear 36 is conducive to the synchronous rotation of the two ball screws 22.

[0025] Furthermore, the main body 1 is equipped with a support rod 11, the support rod 11 penetrates and is fixedly equipped with two fixing plates 34, the support rod 11 penetrates and is movably equipped with two ball nuts 23, the support rod 11 is fixedly equipped with two connecting plates 12, and the bottom of the connecting plate 12 is fixedly equipped with a super vibration unblocking and oil-increasing device 13;

[0026] When working, the whole is fixedly supported by installing the support rod 11. When the super vibration unblocking and oil-increasing device 13 is working, the vibration uses the downhole vibration source to convert the continuous water flow into a fluctuating water flow, thereby eliminating the Jamin effect and the bridge blockage effect in the formation, and loosens and falls off the blocked particles on the surface of the pore, so as to reduce the injection pressure and extend the injection cycle. It can not only make the reservoir skeleton produce vertical and horizontal elastic displacement vibrations, but also make the fluid in the reservoir pores produce pressure waves. Under the joint action of strong longitudinal waves and transverse waves, the purpose of increasing injection is achieved.

[0027] Furthermore, a servo motor 21 is fixedly installed between the two fixing plates 34, and a linkage rod 26 is movably installed on one side of the two fixing plates 34;

[0028] During operation, the servo motor 21 is fixed by two fixing plates 34 , which is beneficial to better load-bearing of the servo motor 21 and ensures stable transmission of the linkage rod 26 .

[0029] Furthermore, the two fixed plates 34 are movably mounted with ball screws 22, and the other ends of the two ball screws 22 are movably mounted with connecting plates 12, and three movable arms 27 are hinged around the fixed plates 34;

[0030] During operation, the ball screw 22 is limited by the fixing plate 34 and the connecting plate 12 so that the ball screw 22 always keeps the same position for rotation, which is beneficial to the stability during operation.

[0031] Furthermore, one side of the three movable arms 27 is hinged with a linkage arm 28 respectively, and the other end of the three linkage arms 28 is hinged with a ball nut 23;

[0032] During operation, the ball nut 23 performs linear movement on the ball screw 22, and the linkage arm 28 generates linkage with the movable arm 27. Driven by the force, the movable arm 27 performs circular movement with the hinge of the fixed plate 34 as the axis.

[0033] Further, a stepper motor 29 is fixedly mounted on one side of the movable arm 27, a first bevel gear 31 is fixedly mounted on the output end of the stepper motor 29, a second bevel gear 32 is transmission-connected to one side of the first bevel gear 31, a movable wheel 33 is fixedly mounted on one side of the second bevel gear 32, and the movable wheel 33 and the movable arm 27 are movably mounted;

[0034] During operation, the first bevel gear 31 is rotated by driving the stepping motor 29, and the direction of the rotational motion is converted by the cooperation of the first bevel gear 31 and the second bevel gear 32, which is conducive to the rotation of the movable wheel 33 at one end of the movable arm 27 to ensure the overall movement in the oil well.

[0035] Working principle: The ball screw 22 is driven by the servo motor 21 to rotate. The ball screw 22 is threaded with the ball nut 23 during operation, and the rotational movement of the ball screw 22 is converted into the linear movement of the ball nut 23. When the ball nut 23 moves, the linkage arm 28 is used to link one side of the movable arm 27, so that the movable arm 27 moves relative to the movement, and moves in a circle with the hinge of one end with the fixed plate 34 as the axis. At this time, the movable wheel 33 at one end of the movable arm 27 is extended outward or inward to move the oil well wall relative to the oil well wall. At the same time, the ball screw 22 drives the first gear 24 to transmit the second gear 25, and the linkage rod 26 generates linkage with the third gear 35, so that the third gear 35 transmits rotational power to the fourth gear 36 on one side, and another ball screw 22 is fixedly installed on one side of the fourth gear 36 to realize the synchronous rotation of the two ball screws 22, so that the six movable wheels 33 are closely fitted to the oil well wall, and the stepper motor 29 is driven to make the first bevel gear 31 transmit the second bevel gear 32 and the movable wheel 33, so that the whole moves inside the oil well during work.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
