Description

Technical Field

[0001] This invention relates to the field of drilling technology, and more specifically to an anti-deviation device, an anti-deviation device control method, an electronic device, and a readable storage medium. Background Technology

[0002] Current vertical drilling tools primarily work by monitoring downhole inclination data using sensors, and then using a data processing program embedded in a circuit board to perform closed-loop control of the push-action components to push against the well wall to prevent and correct inclination.

[0003] With the development of deep and ultra-deep well drilling technology, the combined effects of increased vibration caused by hard formations and increased flexibility due to smaller drill string sizes have led to premature tool damage and drill bit failure during downhole drilling with existing static push-and-pull vertical drilling tools, severely impacting drilling efficiency. Because vertical drilling tools are electromechanical-hydraulic integrated, high-frequency impacts with the rigid support of the wellbore during high-speed rotation cause rapid tool wear, hindering long-term downhole operation. Simultaneously, the internal electronic components are severely affected by strong vibrations, leading to serious circuit failures due to component damage, solder joint detachment, and other issues. Furthermore, ineffective drilling due to tool failure increases drilling costs and severely impacts drilling efficiency. On the other hand, the existing problems of stick-slip and drill jumping, which exist when the drill bit is under pressure cutting the formation and is affected by the increased flexibility of the drill string, are further aggravated by the increased reverse push and correction force. The rock-breaking efficiency of the drill bit is affected, and the problem of preventing deviation in deep and difficult formations but not significantly increasing drilling speed has become an urgent problem to be solved. Moreover, the problem of premature drill bit damage is aggravated, and the lifespan does not reach the expected level, which limits further reduction in drilling costs. Summary of the Invention

[0004] The purpose of this invention is to provide an anti-deviation device, an anti-deviation device control method, an electronic device, and a readable storage medium to solve the problems mentioned above, such as premature tool damage, premature drill bit failure, rapid tool wear, short working life, and high drilling costs caused by strong vibrations during drilling.

[0005] To achieve the above objectives, in a first aspect, embodiments of the present invention provide an anti-deviation device for reducing the tilting and vibration of the drill string during drilling, the device comprising:

[0006] A center rod is connected to the drill bit and rotates with the drill bit. An outer shell is rotatably fitted over the center rod.

[0007] A vibration measuring mechanism is installed on the outer casing and is used to measure the vibration value of the central rod;

[0008] An inclination measuring mechanism, mounted on the outer casing, is used to measure the inclination parameters of the central rod;

[0009] Multiple pushing mechanisms are spaced apart on the outer casing along the radial direction of the central rod, and are used to generate pushing force when in the extended state by contacting the well wall, so as to reduce the tilting and vibration of the drill string.

[0010] Optionally, the pushing mechanism includes:

[0011] A push plate, wherein the rotating end of the push plate is rotatably mounted on the outer casing;

[0012] A pushing mechanism is mounted on the outer casing and located between the outer casing and the push plate. The driving end of the pushing mechanism is connected to the movable end of the push plate. Multiple push mechanisms, when extended, can contact the well wall to generate a pushing force, thereby reducing the tilting and vibration of the drill string.

[0013] Optionally, the outer casing is provided with a limiting protrusion;

[0014] The movable end of the push plate is provided with a limiting part, which is used to contact the limiting protrusion when the movable end of the push plate extends to a preset position, so as to limit the extension amount of the movable end of the push plate.

[0015] Optionally, the actuation mechanism includes a hydraulic cylinder or an electric cylinder.

[0016] Optionally, the anti-tilt device further includes:

[0017] The controller, mounted on the outer casing, is connected to the vibration measurement mechanism, the tilt measurement mechanism, and each pushing mechanism, and is used to control the operation of the corresponding pushing mechanism based on the vibration value and tilt parameters.

[0018] Optionally, the anti-tilt device further includes:

[0019] A short section is connected to the central rod. The short section is hollow inside and is equipped with a power supply and communication module.

[0020] The power supply is used to supply power to the vibration measurement mechanism, the tilt measurement mechanism, the controller, and the pushing mechanism;

[0021] The communication module is connected to the controller and is used to send vibration values ​​and tilt parameters to a remote server.

[0022] Secondly, embodiments of the present invention also provide a method for controlling an anti-tilt device, applied to the aforementioned anti-tilt device, the method comprising:

[0023] The vibration value and tilt parameters of the center rod during drilling are obtained, and the tilt parameters include tilt direction and tilt degree;

[0024] If the tilt angle is determined to be less than or equal to the preset tilt threshold, then based on the current vibration value, control all pushing mechanisms to output the corresponding pushing force.

[0025] If the tilt angle is determined to be greater than the preset tilt threshold, then based on the current tilt direction, all the pushing mechanisms are divided into the first target pushing mechanism and the second target pushing mechanism. Based on the current vibration value, the first target pushing mechanism and the second target pushing mechanism are controlled to output the corresponding pushing force. Among them, the resultant force direction of the pushing mechanism in the first target pushing mechanism is opposite to the tilt direction of the central rod.

[0026] Optionally, based on the current vibration value, control all pushing mechanisms to output a corresponding pushing force, including:

[0027] If the vibration value is less than the first vibration threshold, then the pushing force output by all pushing mechanisms will be the first preset pushing force.

[0028] If the vibration value is greater than or equal to the first vibration threshold and less than or equal to the second vibration threshold, then the pushing force output by all pushing mechanisms is the second preset pushing force.

[0029] If the vibration value is greater than the second vibration threshold, then control all pushing mechanisms to stop outputting pushing force;

[0030] Among them, the first vibration threshold is less than the second vibration threshold; the first preset pushing force is less than the second preset pushing force.

[0031] Optionally, based on the current vibration value, control the first target pushing mechanism and the second target pushing mechanism to output a corresponding pushing force, including:

[0032] If the vibration value is less than the first vibration threshold, the resultant force of the pushing force output by the pushing mechanism in the first target pushing mechanism is controlled to be the third preset pushing force, and the pushing force output by each pushing mechanism in the second target pushing mechanism is controlled to be the first preset pushing force.

[0033] If the vibration value is greater than or equal to the first vibration threshold and less than or equal to the second vibration threshold, then the resultant force of the pushing force output by the pushing mechanism in the first target pushing mechanism is controlled to be the fourth preset pushing force, and the pushing force output by each pushing mechanism in the second target pushing mechanism is controlled to be the second preset pushing force.

[0034] If the vibration value is greater than the second vibration threshold, the resultant force of the pushing force output by the pushing mechanism in the first target pushing mechanism is controlled to be the fifth preset pushing force, and the pushing force output by each pushing mechanism in the second target pushing mechanism is controlled to be the second preset pushing force.

[0035] Among them, the first vibration threshold is less than the second vibration threshold; the first preset pushing force, the second preset pushing force, the third preset pushing force, the fourth preset pushing force and the fifth preset pushing force increase sequentially.

[0036] Optionally, the method further includes:

[0037] From the moment when the resultant force of the pushing force output by the first target pushing mechanism reaches the fifth preset pushing force, if it is determined that the vibration value is always greater than the second vibration threshold within a preset time period, the drilling pressure of the drill bit is reduced to the preset drilling pressure according to the preset amplitude.

[0038] Thirdly, embodiments of the present invention also provide an anti-tilt device control device, the device comprising:

[0039] The parameter acquisition module is used to acquire the vibration value and tilt parameters of the center rod during the drilling process, wherein the tilt parameters include the tilt direction and the tilt angle.

[0040] The judgment and control module is used to, based on the current vibration value, control all pushing mechanisms to output a corresponding pushing force when the tilt angle is less than or equal to a preset tilt threshold; and

[0041] When the tilt angle is greater than a preset tilt threshold, based on the tilt direction, all the pushing mechanisms are divided into a first target pushing mechanism and a second target pushing mechanism. Based on the current corresponding vibration value, the first target pushing mechanism and the second target pushing mechanism are controlled to output a corresponding pushing force. Among them, the resultant force direction of the pushing mechanism in the first target pushing mechanism is opposite to the tilt direction of the central rod.

[0042] Fourthly, embodiments of the present invention also provide an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the above-described anti-tilt device control method.

[0043] Fifthly, embodiments of the present invention also provide a readable storage medium storing instructions that cause a machine to execute the above-described anti-tilt device control method.

[0044] This technical solution has a simple structure, is easy to use, and has a wide range of applications. By using multiple pushing mechanisms to generate pushing force, it can effectively reduce the tilting and vibration of the drill string during the drilling process, effectively avoid rapid damage to the drill string during the drilling process, improve the life of the drill string, ensure stable drilling pressure at the drill bit, and reduce drilling costs.

[0058] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0059] In the embodiments of the present invention, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product of the invention is usually placed when in use.

[0060] The terms “first,” “second,” “third,” etc., are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0061] The terms "parallel" and "perpendicular" do not mean that the components must be absolutely parallel or perpendicular, but rather that they can be slightly tilted. For example, "parallel" simply means that its direction is more parallel than "perpendicular," not that the structure must be completely parallel, but that it can be slightly tilted.

[0062] The terms "horizontal," "vertical," and "sag" do not imply that a component must be absolutely horizontal, vertical, or sagging, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0063] Furthermore, terms like "roughly" and "basically" are used to indicate that the content does not require absolute precision, but rather allows for a certain degree of deviation. For example, "roughly equal" does not simply mean absolute equality; in actual production and operation, achieving absolute "equality" is difficult, and a certain degree of deviation is generally present. Therefore, besides absolute equality, "roughly equal to" also includes the aforementioned situation where a certain degree of deviation exists. Using this as an example, in other cases, unless otherwise specified, terms like "roughly" and "basically" have similar meanings.

[0064] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0065] Limitations of the embodiments are as follows. In the accompanying drawings:

[0066] Figure 1 This is a cross-sectional structural diagram of the anti-tilt device provided by the present invention; Figure 2 This is a top view of the anti-tilt device provided by the present invention; Figure 3 This is a flowchart of the anti-tilt device control method provided by the present invention; Figure 4 This is a schematic diagram of the structure of the anti-tilt device control device provided by the present invention; Figure 5 This is a schematic diagram of the anti-tilt device structure and the direction of the pushing force in Embodiments 1 and 2 provided by the present invention.

[0067] like Figure 1-2 As shown, this embodiment provides an anti-deviation device for reducing drill string tilting and vibration during drilling. The device includes:

[0068] A center rod 1 is connected to the drill bit and rotates with the drill bit. An outer shell 2 is rotatably sleeved on the outside of the center rod 1.

[0069] Vibration measuring mechanism 3 is installed on the outer shell 2 and is used to measure the vibration value of the central rod 1;

[0070] Inclination measuring mechanism 4 is installed on the outer casing 2 and is used to measure the inclination parameters of the center rod 1;

[0071] Multiple pushing mechanisms 5 are arranged at intervals on the outer casing 2 along the radial direction of the central rod 1. When extended, the multiple pushing mechanisms 5 contact the well wall and generate pushing force to reduce the tilting and vibration of the drill string.

[0072] Specifically, in this embodiment, a bearing can be used to achieve a rotatable connection between the center rod 1 and the outer shell 2, which can both limit the movement and reduce the transmission of vibration. Meanwhile, to achieve better drilling, the outer surface of the outer shell 2 is designed to be without structural protrusions. Therefore, the vibration measuring mechanism 3 and the tilt measuring mechanism 4 need to be placed on the inner surface of the outer shell 2, and the pushing mechanism 5 needs to be placed inside the shell wall of the outer shell 2. Correspondingly, to provide sufficient installation space, a groove can be provided at the corresponding position of the center rod 1 to accommodate the vibration measuring mechanism 3, the tilt measuring mechanism 4, and the pushing mechanism 5. Mechanism 3 can be configured as a vibration sensor with a vibration monitoring range of 0-20g (three-axis mean square value). Inclination measuring mechanism 4 is configured as an acceleration sensor with three orthogonal axes, where the x-axis and y-axis are tool faces and the z-axis is vertical. When the well inclination changes, the ratio of the x-axis to the y-axis will be pushed out of the tool face, thereby accurately determining the inclination parameters, including inclination degree and inclination direction, with an inclination monitoring range of 0-5°. When installing inclination measuring mechanism 4, one of its axes is aligned with the thrust output direction of any of the pushing mechanisms 5, thereby specifying the inclination direction and enabling targeted control of the pushing force of the pushing mechanism 5.

[0073] Preferably, the pushing mechanism 5 can be configured as three, arranged in an equilateral triangle structure; or it can be configured as four, arranged in a square structure. Among these, the control method corresponding to three pushing mechanisms 5 is the simplest and has the lowest cost.

[0074] Furthermore, the pushing mechanism 5 includes:

[0075] Push plate 51, the rotating end of which is rotatably mounted on the outer shell 2;

[0076] A pushing mechanism 52 is disposed on the outer shell 2, located between the outer shell 2 and the push plate 51. The driving end of the pushing mechanism 52 is connected to the movable end of the push plate 51, and is used to push the movable end of the push plate 51 to extend and contact the well wall, and to push the push plate 51 to reset.

[0077] Specifically, in this embodiment, the pushing mechanism 5 is configured to include a pushing plate 51 and a pushing mechanism 52. The rotating end of the pushing plate 51 is rotatably mounted on the outer casing 2, allowing it to rotate around an axis and define its position. The pushing mechanism 52 provides the pushing force, pushing the movable end of the pushing plate 51 to extend, thereby achieving contact with the well wall. This method results in a simple structure, high contact strength, and long service life. The maximum output thrust of the pushing mechanism 52 is 50kN.

[0078] Preferably, the driving mechanism 52 is a hydraulic cylinder or an electric cylinder. Using a hydraulic cylinder or electric cylinder for driving has the advantages of simple structure, high control precision, and good thrust stability.

[0079] Furthermore, the outer shell 2 is provided with a limiting protrusion 21;

[0080] The movable end of the push plate 51 is provided with a limiting part 511. The limiting part 511 is used to contact the limiting protrusion 21 when the movable end of the push plate 51 extends to a preset position, so as to limit the extension amount of the movable end of the push plate 51.

[0081] Specifically, in this embodiment, by providing a limiting protrusion 21 on the outer shell 2, when the pushing mechanism 52 pushes the push plate 51 to extend to the predetermined position, the limiting part 511 at the movable end of the push plate 51 will abut against the limiting protrusion 21, thereby restricting the push plate 51 from continuing to extend outward, protecting the push plate 51, avoiding equipment damage due to control failure of the pushing mechanism 52, and ensuring operational safety.

[0082] Furthermore, the anti-tilt device also includes:

[0083] The controller 6 is mounted on the outer casing 2 and connected to the vibration measuring mechanism 3, the tilt measuring mechanism 4, and each push mechanism 5. It is used to control the operation of the corresponding push mechanism 5 based on the vibration value and tilt parameters.

[0084] Specifically, in this embodiment, a controller 6 is provided inside the outer casing 2. The controller 6 controls the corresponding pushing mechanism 5 to work based on the vibration value and tilt parameters, thereby automatically adjusting and controlling according to the actual operating parameters, which can ensure control accuracy and effectively reduce the tilt and vibration of the drill bit.

[0085] Furthermore, the anti-tilt device also includes:

[0086] The short section 7 is connected to the central rod 1. The short section 7 is hollow inside and is equipped with a power supply 71 and a communication module 72.

[0087] The power supply 71 is used to supply power to the vibration measuring mechanism 3, the tilt measuring mechanism 4, the controller 6, and the pushing mechanism 5;

[0088] The communication module 72 is connected to the controller 6 and is used to send vibration values ​​and tilt parameters to a remote server.

[0089] Specifically, in order to ensure the normal operation of the anti-tilt device, a short section is installed on the central rod 1, and a power supply is set in the short section to supply power to the anti-tilt device; in addition, in order to ensure data traceability, a communication module 72 is set in the short section 7. The communication module 72 is connected to the controller 6 and can send the vibration value measured by the vibration measuring mechanism 3 and the tilt parameter measured by the tilt measuring mechanism 4 to a remote server for storage.

[0090] like Figure 3 As shown, this embodiment provides a method for controlling an anti-tilt device, applied to the aforementioned anti-tilt device. The method includes:

[0091] The vibration value and tilt parameters of the center rod during drilling are obtained, and the tilt parameters include tilt direction and tilt degree;

[0092] If the tilt angle is determined to be less than or equal to the preset tilt threshold, then based on the current vibration value, control all pushing mechanisms to output the corresponding pushing force.

[0093] If the tilt angle is determined to be greater than the preset tilt threshold, then based on the current tilt direction, all the pushing mechanisms are divided into the first target pushing mechanism and the second target pushing mechanism. Based on the current vibration value, the first target pushing mechanism and the second target pushing mechanism are controlled to output the corresponding pushing force. Among them, the resultant force direction of the pushing mechanism in the first target pushing mechanism is opposite to the tilt direction of the central rod.

[0094] Specifically, after acquiring the data, the magnitude of the inclination is first determined. Different control methods are adopted for different inclinations to ensure the accuracy of control, effectively reduce the inclination and vibration of the drill string, avoid rapid damage to the drill string during the drilling process, and improve the life of the drill string.

[0095] In the first scenario, if the inclination is less than or equal to a preset inclination threshold, then based on the vibration value, all pushing mechanisms are controlled to output a corresponding pushing force. In this scheme, since the inclination is less than the preset inclination threshold, the inclination angle is small, and the drill string is considered to be centered during drilling. Therefore, all pushing mechanisms output the same pushing force. Furthermore, the pushing force output by the pushing mechanisms differs for different vibration values, specifically including:

[0096] If the vibration value is less than the first vibration threshold, then the pushing force output by all pushing mechanisms will be the first preset pushing force.

[0097] If the vibration value is greater than or equal to the first vibration threshold and less than or equal to the second vibration threshold, then the pushing force output by all pushing mechanisms is the second preset pushing force.

[0098] If the vibration value is greater than the second vibration threshold, then control all pushing mechanisms to stop outputting pushing force;

[0099] Among them, the first vibration threshold is less than the second vibration threshold; the first preset pushing force is less than the second preset pushing force.

[0100] In the second case, if the tilt angle is greater than the preset tilt threshold, then based on the tilt direction, all the pushing mechanisms are divided into a first target pushing mechanism and a second target pushing mechanism. Based on the vibration value, the first target pushing mechanism and the second target pushing mechanism are controlled to output a corresponding pushing force. Among them, the resultant force direction of the pushing mechanism in the first target pushing mechanism is opposite to the tilt direction of the central rod. In this scheme, since the inclination is greater than the preset inclination threshold, the inclination angle is relatively large, which is considered as drilling with the drill string tilted. Therefore, it is necessary to output different pushing forces for different pushing mechanisms according to the inclination direction of the drill string (center rod). Thus, based on the inclination direction, all pushing mechanisms are divided into two categories: one is the first target pushing mechanism, in which the resultant force direction of the pushing mechanisms is opposite to the inclination direction of the center rod. Therefore, when there are two or more pushing mechanisms, the pushing force between the two pushing mechanisms needs to be determined based on the inclination angle and the angle between the two pushing mechanisms. For the other category, the second target pushing mechanism, the same pushing force is output for all of them. Furthermore, the pushing force output by the pushing mechanism is different for different vibration values, specifically including:

[0101] If the vibration value is less than the first vibration threshold, the resultant force of the pushing force output by the pushing mechanism in the first target pushing mechanism is controlled to be the third preset pushing force, and the pushing force output by each pushing mechanism in the second target pushing mechanism is controlled to be the first preset pushing force.

[0102] If the vibration value is greater than or equal to the first vibration threshold and less than or equal to the second vibration threshold, then the resultant force of the pushing force output by the pushing mechanism in the first target pushing mechanism is controlled to be the fourth preset pushing force, and the pushing force output by each pushing mechanism in the second target pushing mechanism is controlled to be the second preset pushing force.

[0103] If the vibration value is greater than the second vibration threshold, the resultant force of the pushing force output by the pushing mechanism in the first target pushing mechanism is controlled to be the fifth preset pushing force, and the pushing force output by each pushing mechanism in the second target pushing mechanism is controlled to be the second preset pushing force.

[0104] Among them, the first vibration threshold is less than the second vibration threshold; the first preset pushing force is less than the second preset pushing force, the second preset pushing force is less than the third preset pushing force, the third preset pushing force is less than the fourth preset pushing force, and the fourth preset pushing force is less than the fifth preset pushing force.

[0105] More specifically, since the relative positions of each pushing mechanism are fixed and also relative to the position of the tilt measuring mechanism, the tilt angle of the central rod can be accurately determined by measuring the tilt angle of the tilt measuring mechanism, thus accurately dividing the first target pushing mechanism into the second target pushing mechanism. Therefore, the resultant pushing force output by the pushing mechanisms in the first target pushing mechanism can be calculated. Calculating the pushing force of each pushing mechanism given the resultant force between the pushing mechanisms and the angle between the pushing mechanisms and the resultant force is prior art known to those skilled in the art and will not be elaborated here.

[0106] Furthermore, the method also includes:

[0107] From the moment when the resultant force of the pushing force output by the first target pushing mechanism reaches the fifth preset pushing force, if the vibration value is always greater than the second vibration threshold within a preset time period, the drilling pressure of the drill bit is reduced to the preset drilling pressure according to the preset amplitude.

[0108] Specifically, in this embodiment, for the second case, if the inclination is greater than a preset inclination threshold, all the pushing mechanisms are divided into a first target pushing mechanism and a second target pushing mechanism based on the inclination direction. Based on the vibration value, the first target pushing mechanism and the second target pushing mechanism are controlled to output a corresponding pushing force. Through the above control method, the inclination angle and vibration of the drill bit can be reduced. However, from the moment when the combined pushing force output by the pushing mechanism in the first target pushing mechanism reaches the fifth preset pushing force, if the vibration value is always greater than the second vibration threshold within a preset time period, it indicates that the vibration and inclination have not been effectively reduced after the pushing force is applied, and there is a certain safety risk in continuing to operate. Therefore, it is necessary to control the drilling pressure of the drill bit to be reduced to the preset drilling pressure according to the preset range.

[0109] In summary, this solution utilizes real-time collected vibration and wellbore deviation data for integrated processing, combining the control of the force exerted by the three push mechanisms with drilling parameter adjustments to achieve closed-loop anti-deviation drilling. This departs from the previous closed-loop control mode relying solely on wellbore deviation measurement, improving the adaptability of vertical drilling tools to strong vibrations and highly inclined formations. It enables the tool to automatically and in real-time adjust its operating parameters based on working conditions downhole, providing a superior operational control method for long-life downhole tools, thereby increasing tool life and reducing tool failure rates. Simultaneously, by changing the control mode and mitigating vibration, it ensures stable drilling pressure at the drill bit, alleviating the problem of rapid drill bit damage during deep well drilling, increasing drill bit life, and improving overall efficiency. This effectively solves the problem of insufficient speed increase in anti-deviation measures in deep, difficult-to-drill formations, contributing to improved drilling quality and efficiency.

[0110] like Figure 4 As shown, this embodiment provides an anti-tilt device control device, the device comprising:

[0111] The parameter acquisition module is used to acquire the vibration value and tilt parameters of the center rod during the drilling process, wherein the tilt parameters include the tilt direction and the tilt angle.

[0112] The judgment and control module is used to, based on the current vibration value, control all pushing mechanisms to output a corresponding pushing force when the tilt angle is less than or equal to a preset tilt threshold; and

[0113] When the tilt angle is greater than a preset tilt threshold, based on the tilt direction, all the pushing mechanisms are divided into a first target pushing mechanism and a second target pushing mechanism. Based on the current corresponding vibration value, the first target pushing mechanism and the second target pushing mechanism are controlled to output a corresponding pushing force. Among them, the resultant force direction of the pushing mechanism in the first target pushing mechanism is opposite to the tilt direction of the central rod.

[0114] Example 1

[0115] like Figure 5 As shown, in this embodiment, the anti-tilt device is equipped with three pushing mechanisms 5, arranged in an equilateral triangle structure, including a first pushing mechanism, a second pushing mechanism, and a third pushing mechanism, respectively. The preset tilt threshold is set to 0.5 degrees. The tilt measuring mechanism 4 measures a tilt of 0.3 degrees, and the tilt direction coincides with the direction of the first pushing mechanism. Since the tilt is less than the preset tilt threshold, and the vibration value is measured in real time by the vibration measuring mechanism 3, it includes the following three cases:

[0116] (1) When the downhole vibration is within 5g, the pushing force (F1, F2 and F3) output by the three pushing mechanisms is 5kN;

[0117] (2) When the downhole vibration is between 5-10g, the pushing force (F1, F2 and F3) output by the three pushing mechanisms is 10kN;

[0118] (3) When the downhole vibration is greater than 10g, stop the push mechanism and carry out drilling parameter reduction operation.

[0119] Example 2

[0120] like Figure 5 As shown, in this embodiment, the anti-tilt device is equipped with three pushing mechanisms 5, arranged in an equilateral triangle structure, including a first pushing mechanism, a second pushing mechanism, and a third pushing mechanism, respectively. The preset tilt threshold is set to 0.5 degrees. The tilt measuring mechanism 4 measures a tilt of 0.7 degrees, and the tilt direction coincides with the direction of the first pushing mechanism. Since the tilt is greater than the preset tilt threshold, the second and third pushing mechanisms are designated as the first target pushing mechanisms, and the first pushing mechanism is designated as the second target pushing mechanism.
