Detailed Implementation

[0020] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of methods consistent with some aspects of this application as detailed in the appended claims.

[0021] The method provided in this application can be executed by a computer device, which refers to an electronic device with data computing, processing, and storage capabilities. This computer device can be a terminal such as a PC (Personal Computer), tablet computer, smartphone, wearable device, or intelligent robot; or it can be a server. The server can be an independent physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services.

[0022] The technical solution of this application will be described and illustrated below through several embodiments.

[0023] Please refer to Figure 1 The diagram illustrates a flowchart of an angle adjustment method according to an embodiment of this application. In this embodiment, the method is primarily illustrated by its application to the computer device described above. The method may include at least one of the following steps (110-140).

[0024] Step 110: Receive an instruction for the angle adjustment device, the instruction being used to adjust the rotation angle of the rotary joint assembly.

[0025] In some embodiments, the angle adjustment device includes a hydraulic linkage, a rotary assembly, a rotary joint assembly, a gear ring, and a push rod unit. In some embodiments, such as... Figure 2 As shown, the angle adjustment device includes a pulse control unit 100, a rotation assembly 200, a translation unit 300, a housing assembly 400, and a rotary joint assembly 500.

[0026] In some embodiments, the pulse control unit 100 is configured to receive or generate instructions for the angle adjustment device, and control the angle adjustment device to adjust the bending angle according to the instructions. In some embodiments, the instructions are transmitted via pulse control signals.

[0027] Step 120: According to the instruction, control the hydraulic connecting rod to move in the first direction. The hydraulic connecting rod drives the rotating assembly and the rotary joint assembly to move a first distance in the first direction, so that the toothed ring disengages from the tooth surface of the rotary joint assembly.

[0028] In some embodiments, the first direction is the direction in which the rotary joint is located. In some embodiments, such as Figure 3 As shown, the rotating assembly 200 includes: a hydraulic unit 201, a hydraulic connecting rod 202, a screw locking cap 203, and a screw 204. In some embodiments, such as Figure 4 As shown, the lead of the sliding sleeve 303 and the screw rod 204 can be set as P, with the unit being mm (millimeter).

[0029] In some embodiments, such as Figure 2 As shown, the rotation angle of the rotary joint assembly 500 relative to the axis 510 of the angle adjustment device is variable and adjustable. This angle is called the bend angle, which can be represented as γ. If γ is 0°, it means that the bend angle of the rotary joint assembly 500 is 0°, that is, the angle adjustment device is straight and no bend angle is formed.

[0030] Step 130: Control the push rod unit to move a second distance in the second direction, and the push rod unit drives the rotary joint assembly to rotate a first angle.

[0031] In some embodiments, such as Figure 3 , Figure 5 , Figure 6 , Figure 10 As shown, the angle adjustment device also includes a sliding sleeve connecting rod 302, a sliding sleeve 303, a spiral rod 204, and a toothed ball seat 502. The push rod unit is controlled to move a second distance in a second direction, and the push rod unit drives the rotary joint assembly to rotate a first angle. This includes: the push rod unit driving the sliding sleeve connecting rod and the sliding sleeve to move in a second direction; the sliding sleeve pushing the spiral rod to rotate; and the teeth of the spiral rod meshing with the toothed ball seat, driving the rotary joint to rotate a first angle.

[0032] In some embodiments, such as Figure 5 , Figure 6 As shown, the translation unit 300 includes: a push rod unit 301, a sliding sleeve connecting rod 302, and a sliding sleeve 303. In some embodiments, the push rod unit is an electric push rod unit, and the electric push rod unit is connected to a cable. In some embodiments, the sliding sleeve 303 is sleeved on the sliding sleeve connecting rod 302, and when the sliding sleeve connecting rod rotates, it will drive the sliding sleeve to move along the axial direction of the sliding sleeve connecting rod.

[0033] In some embodiments, such as Figure 7 , Figure 8 As shown, the housing assembly 400 includes: a housing 401, a bolt 402, a fixing key 403, and a toothed ring 404. In some embodiments, the toothed ring 404 and the rotary joint 503 have n teeth, and the central angle corresponding to each tooth is 360° / n. In some embodiments, the number of teeth can be 20 (i.e., n=20), then the central angle corresponding to each tooth is 18°. Of course, the number of teeth n and the central angle corresponding to each tooth can have other values, which can be set by those skilled in the art, and this application embodiment does not specifically limit them.

[0034] In some embodiments, such as Figure 9 , Figure 10 , Figure 11 As shown, the rotary joint assembly 500 includes: a joint locking cap 501, a toothed ball seat 502, and a rotary joint 503. In some embodiments, such as Figure 11As shown, the rotary joint 503 has a guide sealing step and a drilling fluid circulation channel. In some embodiments, the teeth of the helical rod are spherical teeth, and the toothed ball seat 502 is a spherical tooth seat, also referred to as a toothed ball seat.

[0035] In some embodiments, the mating end faces of the housing 401 and the rotary joint 503 are inclined planes, and the angle between them and the cross-section perpendicular to the centerline is called the inclined plane angle β. In some embodiments, the inclined plane angle β can be 2°. Of course, the inclined plane angle β can also have other values, which can be set by relevant technicians. This application embodiment does not specifically limit this.

[0036] Step 140: Control the hydraulic connecting rod to move in a third direction, which is opposite to the first direction. The hydraulic connecting rod drives the rotating assembly and the rotary joint assembly to move a first distance in the second direction, so that the toothed ring meshes with the tooth surface of the rotary joint assembly.

[0037] In some implementations, after rotating the rotary assembly and rotary joint to the desired bend angle, the hydraulic linkage can be controlled to move in a third direction, so that the toothed ring meshes with the tooth surface of the rotary joint assembly, thereby locking the bend angle and making the adjusted bend angle difficult to change.

[0038] In summary, the technical solution provided in this application, by controlling the hydraulic connecting rod and push rod unit to drive other components based on ground commands when the drill string has been lowered into the well, enables downhole adjustment of the bend angle of the rotary joint of the angle adjustment device. This allows for control and adjustment of the drilling angle and direction without tripping the drill string, reducing the frequency of tripping the drill string and thus improving drilling efficiency.

[0039] In some possible implementations, the first direction is the direction in which the rotary joint is located; when adjusting from a small angle to a large angle, the second direction is the direction in which the rotary joint is located; when adjusting from a large angle to a small angle, the second direction is the direction in which the hydraulic unit is located.

[0040] In some embodiments, if the structural bend angle is 0°, it is straight. When the structural bend angle needs to be adjusted to an angle γ, the rotary joint rotates by an angle θ, and the sliding sleeve moves a distance L. Then, the structural bend angle γ, the bevel angle β, the number of teeth n, the lead P, and the rotation angle θ satisfy the following relationship: Corner:

[0041] Maximum bending angle:

[0042] Slipper travel distance:

[0043] Rotation angle:

[0044] In some embodiments, the structural bend angle needs to be adjusted to γ, which requires the following process: (1) Disengagement of meshing tooth surfaces: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the hydraulic connecting rod 202 to move to the left, causing the rotating assembly 200 and the rotary joint 503 to move to the left by a distance S (S is the minimum safe distance for tooth surface disengagement, which is greater than the tooth height), and the tooth ring 404 disengages from the tooth surface of the rotary joint 503.

[0045] (2) Rotary joint: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the electric push rod unit 301 to move to the left by L, causing the sliding sleeve connecting rod 302 and the sliding sleeve 303 to move to the left. Due to the interaction between the helical teeth of the sliding sleeve 303 and the helical groove of the helical rod 204, the helical rod 204 is pushed to rotate. The spherical teeth of the helical rod 204 mesh with the toothed ball seat 502, which drives the rotary joint 503 to rotate by an angle θ.

[0046] (3) Locking angle: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the hydraulic linkage 202 to move to the right, causing the rotating assembly 200 and the rotary joint assembly 500 to move to the right by a distance S, causing the toothed ring 404 to mesh with the tooth surface of the rotary joint 503, thus locking the angle.

[0047] In some embodiments, if β = 2° and lead P = 500 mm, then the following can be calculated according to the formula: Maximum structural bending angle: The bending angle corresponding to each tooth adjustment is calculated as shown in Table 1 below.

[0048] Table 1

[0049] In some embodiments, adjusting the bend angle from a small angle to a large angle is called positive angle adjustment. For example... Figure 12 As shown, if the initial bend angle is 0°, the structure is straight; when the bend angle needs to be adjusted to γ ​​= 3.24°, the rotation angle of the rotary joint is θ, and the sliding sleeve travels a distance L. Then, the following can be calculated: Rotation angle:

[0050] Slipper travel distance:

[0051] Therefore, the process of adjusting the positive angle is as follows: (1) Disengagement of meshing tooth surfaces: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the hydraulic connecting rod 202 to move towards the rotary joint 503, causing the rotary assembly 200 and the rotary joint 503 to move together towards the rotary joint 503 by a distance S (S is the minimum safe distance for tooth surface disengagement, which is greater than the tooth height), and the tooth ring 404 disengages from the tooth surface of the rotary joint 503.

[0052] (2) Rotary joint: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the electric push rod unit 301 to move 300mm toward the rotary joint 503, causing the sliding sleeve connecting rod 302 and the sliding sleeve 303 to move toward the rotary joint 503. Due to the interaction between the helical teeth of the sliding sleeve 303 and the helical groove of the helical rod 204, the helical rod 204 is pushed to rotate. The spherical teeth of the helical rod 204 mesh with the toothed ball seat 502, causing the rotary joint 503 to rotate 108° (i.e. 3π / 5).

[0053] (3) Locking angle: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the hydraulic connecting rod 202 to move towards the hydraulic unit 201, causing the rotating assembly 200 and the rotary joint assembly 500 to move a distance S towards the hydraulic unit 201, causing the toothed ring 404 to mesh with the tooth surface of the rotary joint 503, locking the angle.

[0054] In some embodiments, adjusting the bend angle from a large angle to a small angle is called reverse angle adjustment. If the bend angle γ needs to be adjusted from 3.24° to 1.82°, the rotary joint 503 needs to rotate in the reverse direction. At this time: Rotation angle:

[0055] Slipper travel distance: mm Therefore, the process of adjusting the reverse angle is as follows: (1) Disengagement of meshing tooth surfaces: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the hydraulic connecting rod 202 to move towards the rotary joint 503, causing the rotary assembly 200 and the rotary joint 503 to move together towards the rotary joint 503 by a distance S (S is the minimum safe distance for tooth surface disengagement, which is greater than the tooth height), and the tooth ring 404 disengages from the tooth surface of the rotary joint 503.

[0056] (2) Rotary joint: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the electric push rod unit 301 to move 150mm toward the hydraulic unit 201, causing the sliding sleeve connecting rod 302 and the sliding sleeve 303 to move toward the hydraulic unit 201. Due to the interaction between the helical teeth of the sliding sleeve 303 and the helical groove of the helical rod 204, the helical rod 204 is pushed to rotate. The spherical teeth of the helical rod 204 mesh with the toothed ball seat 502, causing the rotary joint 503 to rotate 54° (i.e. 3π / 10).

[0057] (3) Locking angle: The ground sends a command signal, the pulse control unit 100 interprets the command and controls the hydraulic connecting rod 202 to move towards the hydraulic unit 201, causing the rotating assembly 200 and the rotary joint assembly 500 to move a distance S towards the hydraulic unit 201, causing the toothed ring 404 to mesh with the tooth surface of the rotary joint 503, locking the angle.

[0058] In some embodiments, the drive housing can be a hydraulic cylinder. A hydraulic cylinder, in conjunction with a check valve, is used to lock the hydraulic cylinder, preventing excessive external force from causing the rotary joint to rotate or its angle to change.

[0059] In the above implementation method, a spherical tooth meshing method is adopted, which eliminates the eccentricity and achieves the purpose of driving the rotary joint to rotate.

[0060] In this embodiment, the control signal pulse can be a mud pulse or a cabled electromagnetic pulse signal. When the downhole tool string is a conventional drilling tool, cableless signal transmission is used, requiring a mud circulation system for signal transmission, which can accurately control the wellbore trajectory. When the downhole tool string is a power tool, cabled signal transmission is used, enabling closed-loop operation both above and below ground. Using cabled electromagnetic pulse signals allows the downhole adjustable device of this application to better perform its functions, achieve real-time adjustment, and more accurately control the wellbore trajectory.

[0061] In this embodiment, the push rod unit is hollow and works in conjunction with the helical rod. It can precisely control the rotation angle of the rotary joint by accurately moving the sliding sleeve, and can achieve step-by-step rotation of the rotary joint angle by moving the sliding sleeve distance.

[0062] The angle adjustment device provided in this application has a simple structural design, simple application principle, reliable performance, and convenient operation. It is of great significance for efficient and rapid drilling of complex well structures such as extended reach wells and long horizontal wells, precise control of well quality, reduction of overall costs, shortening of downhole operation cycle, and improvement of economic benefits.

[0067] The control module 1320 is also used to control the push rod unit to move a second distance in a second direction, and the push rod unit drives the rotary joint assembly to rotate a first angle.

[0068] The control module 1320 is also used to control the hydraulic connecting rod to move in a third direction, which is opposite to the first direction.

[0070] In some embodiments, the teeth of the helical rod are spherical teeth, and the toothed ball seat is a spherical tooth seat.
