Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and in particular to a pipe column anti-tilt device and an anti-tilt method. Background Art

[0002] In the field of drilling, well repair and related fields on the ground, in order to drill wells of different depths, it is usually necessary to set a corresponding number of pipe strings on the drill pipe, and drill wells of corresponding depths by adjusting their lengths. The verticality of the drill pipe and the pipe string is one of the key factors to ensure safe and efficient operations. If the pipe string tilts during the lifting, lowering or moving process, it may not only cause equipment damage, but also cause serious safety accidents, such as pipe string breakage, derrick collapse, etc. The invention patent with publication number CN110469264B discloses a drill pipe guiding device, which has the effect of adapting drill pipes of different sizes by adjusting the spacing between two sets of guide wheels and adjusting the inclination amplitude of the guide wheels, and clamping and positioning them to reduce the swing amount during drilling and excavation, so as to ensure that the drill pipe remains in a vertical state. However, since the drill pipe or tubing does not rotate at the same level while drilling, but descends or rises while rotating, the descent is for drilling, and the ascent is for improving the smoothness of the drill pipe and tubing leaving the well, and the guide wheel of the above-mentioned patent cannot stably support the rising or falling tubing, and a large friction force will be generated at the connection, which will affect the support safety and is not conducive to preventing the tubing from tilting. Therefore, a tubing anti-tilt device and anti-tilt method are proposed to solve the above-mentioned problem. Summary of the invention

[0010] Furthermore, the impurity handling component includes a ring-shaped shielding ring arranged on a support platform, the air outlet is opened on the shielding ring, and an elastic scraping ring is arranged on the shielding ring. The impurity scraping side of the scraping ring is in contact with the corresponding ball, and the scraping ring can scrape impurities on the rotating ball.

[0014] Furthermore, a one-way valve is provided on the support assembly, and an output end of the one-way valve is connected to an input end of the oil injection chamber.

[0015] A method for preventing a pipe column from tilting is as follows:

[0016] S1. Place the bracket outside the pipe column body, with the pipe column body located at the axis of the bracket, and drive each hydraulic rod to start, so that the support assembly moves synchronously until each ball contacts the surface of the pipe column body;

[0017] S2, control the one-way valve to the start state, connect the external lubricating oil to the one-way valve and deliver it to the oil filling chamber until the lubricating oil lubricates all the balls;

[0018] S3, based on steps S1 and S2, driving the pipe string body to rotate and move downward, or driving the pipe string body to rotate and move upward, when the pipe string body descends, it is in the drilling state, and when the pipe string body ascends, it is in the recovery state;

[0019] S4. On the basis of step S3, the blowing device is connected to the air inlet, so that the airflow passes through the guide cavity, the connecting cavity and the air outlet in sequence, and finally is discharged from the air outlet end of the air outlet.

[0021] In the present invention, the bracket is set at the corresponding pipe column body, and the support assembly is driven by each hydraulic rod to move to the side close to the pipe column body until each ball contacts the pipe column body, thereby completing the anti-tilt clamping of the pipe column body. In this process, the universally rotatable ball can be adapted to the pipe column body that moves upward or downward and rotates at the same time, and the lubricating oil is applied to each ball, which can effectively reduce the friction between the pipe column body and the positioning structure when being positioned, thereby ensuring that the wear on the pipe column body is also effectively reduced, so as to prevent damage to the pipe column body and ensure drilling safety.

[0022] In the present invention, through the setting of the impurity handling component, the impurity handling component can prevent impurities from entering the gap where the support component and the ball are connected. When the side of the ball exposed outside the support component is stuck with impurities splashed during drilling, it can scrape off the impurities on the ball, and the blowing equipment guides the airflow to blow out from the air outlet, which can form a positive pressure at the impurity handling component corresponding to the scraped ball. This design can effectively prevent impurities outside the impurity handling component from entering the gap where the support component and the ball are connected, so that the impurities will not cause significant interference to the ball.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figure 1-6The present invention discloses a pipe column anti-tilt device, comprising a bracket 1 and a pipe column body 10. The pipe column body 10 is installed on a drill pipe, and is rotated and moved downward for drilling deeper. It can be detached from the well by rotating and moving upward. The bracket 1 is placed on the ground, and the pipe column body 10 is located at the axis of the bracket 1. A plurality of hydraulic rods 3 are horizontally installed on the bracket 1, and each hydraulic rod 3 is distributed in a ring shape with the axis of the bracket 1 as the center. A support assembly 4 is provided at the telescopic end of each hydraulic rod 3, and the support assembly 4 can cooperate with the hydraulic rod 3 to support and limit the pipe column body 10 located at the axis of the bracket 1.

[0033] In one embodiment, the support assembly 4 includes a strip-shaped and vertically arranged support platform 41, each support platform 41 is connected to the telescopic end of the corresponding hydraulic rod 3, and a plurality of balls 5 are embedded on the support platform 41 from top to bottom. The ball 5 can rotate universally in the support platform 41, and one side of the ball 5 is located outside the support platform 41 and in contact with the column body 10. An oil filling cavity 42 is opened on the support platform 41, and the corresponding oil filling cavity 42 of the support platform 41 can be filled with lubricating oil, and the lubricating oil is guided to be coated on each ball 5. An annular impurity treatment component 7 is arranged at each ball 5 of the support platform 41, and the impurity treatment component 7 can scrape off impurities on the rotating ball 5; the impurity treatment component 7 includes an inclined air outlet 73, and the air outlet end of the air outlet 73 faces the side of the ball 5 away from the support platform 41. The corresponding air outlet 73 of the impurity treatment component 7 can cooperate with a blowing device to guide the airflow to blow out from the air outlet 73, and prevent impurities outside the impurity treatment component 7 from entering it.

[0034] In a specific implementation, the bracket 1 is arranged at the corresponding pipe column body 10, and the support assembly 4 is driven by each hydraulic rod 3 to move to the side close to the pipe column body 10 until each ball 5 contacts the pipe column body 10, thereby completing the anti-tilt clamping of the pipe column body 10. In this process, the universally rotatable ball 5 can be adapted to the pipe column body 10 that moves upward or downward and rotates at the same time, and the lubricating oil is applied to each ball 5, which can effectively reduce the friction between the pipe column body 10 and the positioning structure when being positioned, thereby ensuring that the wear on the pipe column body 10 is also effectively reduced, so as to prevent damage to the pipe column body 10 and ensure drilling safety.

[0035] In addition, through the setting of the impurity handling component 7, the impurity handling component 7 can prevent impurities from entering the gap where the support component 4 and the ball 5 are connected. When the side of the ball 5 exposed outside the support component 4 is stuck with impurities splashed during drilling, it can scrape off the impurities on the ball 5, and the blowing equipment guides the airflow to blow out from the air outlet 73, which can form a positive pressure at the impurity handling component 7 corresponding to the scraped ball 5. This design can effectively prevent impurities outside the impurity handling component 7 from entering the gap where the support component 4 and the ball 5 are connected, so that the impurities will not cause significant interference to the ball 5.

[0036] In one embodiment, the support component 4 also includes an air inlet 43 opened on the support platform 41, and the air inlet 43 is connected to the air outlet end of the blowing device. The blowing device is common knowledge in the field, so the specific structure and working principle are not described in detail herein; the interior of the support platform 41 is provided with a plurality of vertically distributed guide cavities 44 corresponding to each impurity treatment component 7, and the interior of the support platform 41 is also provided with a plurality of connecting cavities 45, each connecting cavity 45 is connected to two adjacent guide cavities 44, and the top guide cavity 44 is connected to the air inlet 43, and each guide cavity 44 is connected to the corresponding air outlet hole 73.

[0037] In a specific implementation, air is blown toward the air inlet 43 through an air blowing device, and the wind passes through each guide cavity 44 and the connecting cavity 45 into each air outlet 73, and is finally blown out from the air outlet end of the air outlet 73, and the impurities attached to the ball 5 and partially entered into the impurity treatment component 7 are blown to the outside of the impurity treatment component 7.

[0038] In one embodiment, the impurity handling component 7 includes a ring-shaped shielding ring 71 installed on the support platform 41. The support platform 41 shields the gap at the connection between the ball 5 and the support platform 41 to prevent impurities from directly entering from there. The air outlet 73 is opened on the shielding ring 71, and an elastic scraper ring 72 is installed on the shielding ring 71. The scraper ring 72 can scrape off impurities on the rotating ball 5.

[0039] In a specific implementation, the outlet end of the air outlet hole 73 faces between the scraper ring 72 and the ball 5, and there is an oil film formed by lubricating oil on the ball 5. When the ball 5 is located on one side outside the impurity treatment component 7 and impurities are stuck to it, and the ball 5 is rotating, the outer wall of the scraper ring 72 will blow away most of the impurities on the ball 5. Combined with the airflow blown out from the air outlet hole 73, an airflow that continuously blows toward the outside of the impurity treatment component 7 can be formed, thereby blowing the impurities entering the shielding ring 71 and the impurities scraped off the ball 5 to the outside of the impurity treatment component 7 for practical use.

[0040] In one embodiment, a soft sealing ring 8 is disposed on the support platform 41 , and the sealing ring 8 may be a soft silicone ring.

[0041] With such a design, the sealing ring 8 can seal the installation gap between the support platform 41 and the ball 5, thereby further preventing impurities from entering the gap.

[0042] In one embodiment, a lifting assembly 2 is installed on the bracket 1, and the lifting assembly 2 can be a linear module, and a scraping assembly 9 is provided at the moving end of the lifting assembly 2. The scraping assembly 9 is staggered with the supporting assembly 4. The lifting assembly 2 can drive the scraping assembly 9 to move to the top or bottom of the supporting assembly 4, and enable the scraping assembly 9 to scrape impurities attached to the pipe column body 10 when it rises or falls.

[0043] In a specific implementation, when the tubular body 10 rotates and descends, the scraper assembly 9 needs to be controlled to move to the top of the support assembly 4; when the tubular body 10 rotates and ascends, the scraper assembly 9 needs to be controlled to move to the bottom of the support assembly 4. With this design, the impurities on the surface of the tubular body 10 can be treated first, and then the tubular body 10 can be brought into contact with the ball 5 after the treatment, so as to prevent the impurities on the surface of the tubular body 10 before use or after drilling from contacting the ball 5, thereby improving the safety of the use of the ball 5.

[0044] In one embodiment, the scraping assembly 9 includes a mounting frame 91 installed at the moving end of the lifting assembly 2, and a telescopic rod 92 is horizontally arranged on the mounting frame 91, wherein the telescopic rod 92 includes a sleeve and a rod body telescopically arranged on the sleeve, and the side of the rod body away from the sleeve is installed on the inner wall of the mounting frame 91, and a plurality of guide plates 95 corresponding to the corresponding sleeves are installed on the inner wall of the mounting frame 91, and each sleeve can be slidably inserted on the corresponding guide plate 95, and the telescopic rod 92 is staggered with the hydraulic rod 3 and the support assembly 4, and a spring 93 is installed on the inner wall of the mounting frame 91, the spring 93 is surrounded by the rod body, and the side of the spring 93 away from the mounting frame 91 abuts against the sleeve in the telescopic rod 92, and the spring 93 can push the sleeve to move toward the side close to the pipe column body 10, and a scraper 94 is arranged on the corresponding sleeve of the telescopic rod 92, and the scraper 94 is in contact with the pipe column body 10.

[0045] In a specific implementation, the spring 93 can extend the telescopic rod 92 and enable the scraper 94 to closely contact the pipe column body 10. When the pipe column body 10 rotates and moves up and down, the scraper 94 can effectively scrape off impurities thereon. Moreover, since both the hydraulic rod 3 and the telescopic rod 92 can be extended and retracted, they can adapt to pipe column bodies 10 of different sizes, thereby improving their applicability.

[0046] In one embodiment, a one-way valve 6 is installed on the supporting assembly 4 , and the output end of the one-way valve 6 is communicated with the input end of the oil injection chamber 42 .

[0047] With such a design, the lubricating oil is injected into the oil filling chamber 42 through the one-way valve 6 , so that the lubricating oil can lubricate each ball 5 .

[0048] Also included is a pipe string anti-tilt method, which is as follows:

[0049] S1, place the bracket 1 outside the pipe column body 10, and the pipe column body 10 is located at the axis of the bracket 1, drive each hydraulic rod 3 to start, and make the support assembly 4 move synchronously until each ball 5 contacts the surface of the pipe column body 10;

[0050] S2, control the one-way valve 6 to the start state, connect the external lubricating oil to the one-way valve 6 and deliver it to the oil filling chamber 42 until the lubricating oil lubricates each ball 5;

[0051] S3, based on steps S1 and S2, driving the pipe string body 10 to rotate and move downward, or driving the pipe string body 10 to rotate and move upward, the pipe string body 10 is in a drilling state when it descends, and is in a recovery state when it ascends;

[0052] S4. On the basis of step S3, the blowing device is connected to the air inlet 43, so that the airflow passes through the guide cavity 44, the connecting cavity 45 and the air outlet 73 in sequence, and finally is discharged from the air outlet end of the air outlet 73. The airflow will form a positive pressure at the contact point between the ball 5 and the column body 10 to prevent impurities from entering the impurity treatment component 7, and the scraper ring 72 will scrape the impurities on the rotating ball 5;

[0053] S5. On the basis of step S4, the corresponding sleeves of each telescopic rod 92 are squeezed by the spring 93, so that the telescopic rod 92 is stretched, and the scraper 94 moves to the side close to the pipe column body 10 due to the stretching until it contacts with it. The scraper 94 scrapes away impurities on the rotating pipe column body 10, and at the same time drives the mounting frame 91 to move up and down through the lifting assembly 2. When the pipe column body 10 is in the drilling state, the scraper 94 is located on the lower side of the support assembly 4; when the pipe column body 10 is in the recovery state, the scraper 94 is located on the upper side of the support assembly 4.
