Description

Technical Field

[0001] The embodiments of the present disclosure relate to the technical field of oil drilling tools, and in particular, to a continuous tubing integrated window opening device. Background Art

[0002] In the integrated window opening device of coiled tubing, the connection methods of the bevel body and the window milling cone are usually threaded connection, welding connection, bayonet connection and key connection. Threaded connection is to process matching threads at the connection part of the bevel body and the window milling cone. Tight connection is achieved by screwing the threads. This connection method has the characteristics of easy disassembly and assembly and stable connection, but it requires high thread processing accuracy. Welding connection is to connect the connection ends of the bevel body and the window milling cone through welding process. Welding can provide a very strong connection, but once a problem occurs, it is difficult to repair and replace. Bayonet connection is to set mutually matching bayonet structures on the bevel body and the window milling cone, and achieve connection through the bayonet engagement. This method has a faster connection speed, but the connection strength may be relatively weak. Key connection is to set keyways and keys at the connection part, and use keys to transmit torque and prevent relative rotation. Key connection can better withstand large torque, but the processing is relatively complicated. Interference fit connection is to achieve a tight fit connection by making the connection part of the bevel body and the window milling cone have a certain interference. Different connection methods have their own advantages and disadvantages. The specific method to be selected depends on factors such as the working conditions, manufacturing process and maintenance requirements of the device.

[0003] In the prior art, various connection methods between the bevel guide and the window milling cone need to meet two requirements. The first requirement is that when the window opening device is sent from the ground to the sealing position, the bevel guide and the window milling cone need to maintain a stable connection and the connection cannot be disconnected to avoid the sealing body from being sealed prematurely. The second requirement is that when the window opening device is sent to the sealing position, the bevel guide and the window milling cone can be disconnected more easily to facilitate the sealing. However, there is a certain contradiction between these two points. If the connection strength is too high, it will be difficult to disconnect, so that it is difficult to separate when sealing; if the connection strength is insufficient, there will be a risk of premature sealing during the process of going down to the well. As a result, the connection between the bevel guide and the window milling cone still has the problem of premature sealing when the sealing body is lowered into the well, and the bevel guide and the window milling cone are difficult to disconnect when the sealing body is sealed. Summary of the invention

[0004] To overcome the above defects, the embodiments of the present disclosure provide an integrated deflector diverter structure, which solves the problems in the related art of premature sealing of the sealing body when it is lowered into the well and difficulty in disconnecting the deflector and the window milling cone when the sealing body is sealed.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1~Figure 5 As shown, it shows a continuous oil pipe integrated window opening device in one embodiment of the present disclosure, including a seat sealing body 1; a guide bevel body 2 is arranged on the seat sealing body 1, and has a guide bevel surface 201; a window opening milling cone 3 is located on one side of the guide bevel surface 201; a screw 4 connects the guide bevel body 2 and the window opening milling cone 3; the window opening milling cone 3 has a first thread segment 301 and a second thread segment 302 arranged at intervals, the guide bevel body 2 has a first thread portion 202 and a second thread portion 203, the first thread portion 201 is connected to the first thread segment 301, and the second thread portion 202 is connected to the second thread segment 302.

[0025] In the present coiled tubing integrated window opening device: the seat sealing body 1 is used as a basic component, carrying the guide bevel body 2 and the window opening milling cone 3, the guide bevel body 2 is arranged on the seat sealing body 1, and its guide bevel surface 201 plays a guiding role, and the window opening milling cone 3 is located on one side of the guide bevel surface 201. In particular, the guide bevel body 2 and the window opening milling cone 3 are connected by screws 4, the window opening milling cone 3 has a first thread segment 301 and a second thread segment 302 arranged at intervals, and the guide bevel body 2 has a corresponding first thread portion 201 and a second thread portion 202, which are connected to each other.

[0026] In practical applications, such as when transporting the window opening device from the ground to the sealing position, this double threaded connection method can provide sufficient connection stability to ensure that the guide bevel 2 and the window opening milling cone 3 will not be accidentally disconnected, thereby avoiding premature sealing of the sealing body.

[0027] When the window opening device reaches the sealing position and needs to perform the sealing operation: due to the threaded connection arranged at intervals, through a specific operation sequence or tool, the disconnection between the guide bevel 2 and the window opening milling cone 3 can be relatively easily achieved, thereby facilitating the sealing.

[0028] The advantages of this design are: first, the spaced double-thread connection ensures a stable connection during the downhole process and can be easily disconnected when needed. Second, it effectively solves the problems of premature sealing when the sealing body is downhole and difficulty in disconnecting when sealing in the existing connection method.

[0029] For example, in a complex underground environment, this connection method can better adapt to the needs of different stages and improve the reliability and operational convenience of the window opening device.

[0030] In terms of technical effects, the stability and detachability of the connection between the guide angle body 2 and the window milling cone 3 are significantly improved. Overall working principle: The double-threaded connection structure set at intervals is used to achieve a stable connection when going down the well and a convenient disconnection when setting the seal. Overall technical effect: The connection performance of the guide angle body and the window milling cone in the integrated window opening device of the continuous tubing is optimized, and the working efficiency and reliability of the device are improved.

[0031] In some examples, the first threaded portion 201 and the second threaded portion 202 are both C-shaped, and the circumferential angle is less than 180°.

[0032] In actual use, such as when connecting or disassembling the bevel guide 2 and the window milling cone 3: this C-shaped design with a circumferential angle less than 180° has unique advantages. Since it is not a complete circumferential thread, when the connection needs to be disconnected, the contact area and friction between the threads can be reduced, making disassembly easier. At the same time, in the connected state, the C-shaped design can still provide sufficient thread engagement length and contact area to ensure the stability and reliability of the connection.

[0033] The advantages of this design are: first, under the premise of ensuring the connection strength, the difficulty of disassembly is reduced and the convenience of operation is improved. Second, it can better adapt to the complex working conditions underground and reduce the delay of operation caused by connection or disassembly difficulties. Third, the first threaded part 201 and the second threaded part 202 are designed to be in relative positions, which can ensure convenient installation while the staggered connection on both sides makes the connection more stable.

[0034] For example, when the window milling cone 3 needs to be quickly replaced in an emergency, the C-type thread portion can save operation time and improve work efficiency.

[0035] In terms of technical effects, the detachable performance of the connection between the guide bevel 2 and the window milling cone 3 is significantly optimized without affecting the stability of the connection. Overall working principle: Through the C-shaped first threaded portion 201 and the second threaded portion 202 with a circumferential angle less than 180°, a balance between stable connection and convenient disassembly is achieved. Overall technical effect: The structure of the threaded portion is improved, and the flexibility of use and maintenance efficiency of the continuous tubing integrated window opening device are enhanced.

[0036] In some examples, the window milling cone 3 includes a milling cone body 303, which has a front milling cone portion 304, a first guide portion 305, a second guide portion 306 and a rear milling cone portion 307 arranged in sequence; a first sliding member 308 is slidably and rotatably arranged on the first guide portion 305, and a first thread segment 301 is formed on the first sliding member 308; a second sliding member 309 is slidably and rotatably arranged on the second guide portion 306, and a second thread segment 302 is formed on the second sliding member 309.

[0037] In the present coiled tubing integrated window opening device, the window opening milling cone 3 comprises a milling cone body 303, a first sliding member 308 and a second sliding member 309. The milling cone body 303 has a front milling cone portion 304, a first guide portion 305, a second guide portion 306 and a rear milling cone portion 307 arranged in sequence.

[0038] In actual work, for example, when performing window opening operations: the front milling cone 304 first contacts the working surface to perform preliminary milling and window opening operations. The first sliding member 308 on the first guide portion 305 can slide and rotate. During the working process, the first sliding member 308 can adaptively adjust the position and angle according to the actual force and working conditions, so as to better cooperate with the guide bevel 2 to achieve stable connection and effective milling. Similarly, the second sliding member 309 on the second guide portion 306 can also play a similar role.

[0039] The advantages of this design are: first, through the sliding and rotating design, the first sliding member 308 and the second sliding member 309 can flexibly adapt to different working conditions and stress conditions, thereby improving the working efficiency and stability of the window milling cone 3. Second, the adaptability and reliability of the connection between the window milling cone 3 and the guide bevel 2 are enhanced, which has a certain buffering effect and reduces the stress concentration and damage risk caused by the fixed connection.

[0040] For example, when encountering complex underground geological structures or uneven forces, the sliding member can automatically adjust to avoid local excessive wear or damage, thereby extending the service life of the window milling cone 3.

[0041] In terms of technical effects, the adaptive ability and connection reliability of the window milling cone 3 are significantly improved. Overall working principle: The first sliding member 308 and the second sliding member 309 that can slide and rotate on the milling cone body 303 are used to achieve flexible adaptation to working conditions and stable connection. Overall technical effect: The structure and performance of the window milling cone 3 are optimized, and the working effect and reliability of the continuous tubing integrated window opening device are improved.

[0042] In some examples, the window milling cone 3 also includes a first elastic member 310, one end of the first elastic member 509310 acts on the first sliding member 308, and the other end acts on the milling cone body 303, providing a force for the first sliding member 308 to approach the second sliding member 309; one end of the second elastic member 509311 acts on the second sliding member 309, and the other end acts on the milling cone body 303, providing a force for the second sliding member 309 to approach the first sliding member 308.

[0043] In the present continuous tubing integrated window opening device, the window opening milling cone 3 also includes a first elastic member 310 and a second elastic member 311. In an actual working scenario, for example, when the window opening milling cone 3 is operating: one end of the first elastic member 310 acts on the first sliding member 308, and the other end acts on the milling cone body 303, always providing a force for the first sliding member 308 to approach the second sliding member 309. This enables the first elastic member 310 to play a role of buffering and resetting when the first sliding member 308 is subjected to an outward force during operation, ensuring that the first sliding member 308 works stably in an appropriate position. Similarly, one end of the second elastic member 311 acts on the second sliding member 309, and the other end acts on the milling cone body 303, providing a force for the second sliding member 309 to approach the first sliding member 308. When the second sliding member 309 is affected by an external force, the second elastic member 311 can play a similar role of buffering and resetting.

[0044] The advantages of this design are: first, through the action of the elastic member, the position of the sliding member can be automatically adjusted to better adapt to different working conditions and force changes, thereby improving the working stability and adaptability of the window milling cone 3. Second, the elastic member can absorb part of the impact force, reduce the rigid collision between the sliding member and the milling cone body, reduce the risk of wear and damage of the components, and extend the service life.

[0045] For example, when encountering sudden large resistance or impact, the elastic parts can effectively buffer and prevent damage to the components, ensuring the continuous window opening operation.

[0046] In terms of technical effects, the stability and reliability of the window milling cone 3 in operation are significantly improved, and the maintenance cost is reduced. Overall working principle: With the elastic force of the first elastic member 310 and the second elastic member 311, the relative position of the first sliding member 308 and the second sliding member 309 is maintained stable, and buffer protection is provided. Overall technical effect: By adding elastic members, the working performance and durability of the window milling cone 3 are optimized.

[0047] In some examples, the milling cone body 303 also has an annular stop edge 312, which is located between the first guide portion 305 and the second guide portion 306, and has a diameter larger than the diameters of the first guide portion 305 and the second guide portion 306, and a diameter smaller than the diameters of the first sliding member 308 and the second sliding member 309; the first elastic member 509310 provides a force for the first sliding member 308 to approach the annular stop edge 312, and the second elastic member 509311 provides a force for the second sliding member 309 to approach the annular stop edge 312.

[0048] This design has the following advantages: First, the annular retaining edge 312 plays a role of limiting, limiting the movement range of the first sliding member 308 and the second sliding member 309 under the action of the elastic member, avoiding position deviation or instability caused by excessive movement. Second, the elastic member makes the sliding member close to the annular retaining edge 312, which can provide a certain pre-tightening force during operation, enhance the connection stability between the sliding member and the milling cone body 303, and also help to better transmit cutting force and torque.

[0049] For example, when encountering complex cutting conditions, the cooperation between the annular retaining edge 312 and the elastic member can ensure that the sliding member is always in a suitable working position, thereby improving the cutting accuracy and efficiency of the window milling cone 3 .

[0050] In terms of technical effects, the position stability and working reliability of the sliding member are significantly improved, thereby optimizing the overall performance of the window milling cone 3. Overall working principle: The position of the first sliding member 308 and the second sliding member 309 are limited and pre-tightened by utilizing the combined effect of the annular retaining edge 312 and the elastic member. Overall technical effect: Through the ingenious structural design, the working stability and performance of the window milling cone 3 under complex working conditions are improved.

[0051] In some examples, the first guide portion 305 and the second guide portion 306 both have an accommodating cavity 313 , and the accommodating cavity 313 is used to accommodate the annular retaining edge 312 .

[0052] In the present coiled tubing integrated window opening device, the first guide portion 305 and the second guide portion 306 both have a receiving cavity 313. In actual operation, for example, when the window opening milling cone 3 is in operation: when the first sliding member 308 and the second sliding member 309 slide on their respective guide portions, the receiving cavity 313 provides a receiving space for the annular retaining edge 312.

[0053] The advantages of this design are: on the one hand, the accommodating cavity 313 enables the annular retaining edge 312 to better play the role of limiting and pre-tightening without affecting the sliding of the sliding member, ensuring that the movement of the sliding member is more stable and accurate. On the other hand, the existence of the accommodating cavity 313 optimizes the structural layout of the milling cone body 303, making the overall structure more compact and reducing unnecessary space occupation.

[0054] For example, in a complex working environment, the compact structure can improve the adaptability and flexibility of the window milling cone 3 .

[0055] In terms of technical effects, the rationality and compactness of the structure are significantly improved, and the working stability and reliability of the window milling cone 3 are further enhanced. Overall working principle: By setting the accommodating cavity 313 in the first guide part 305 and the second guide part 306, a suitable space is provided for the annular retaining edge 312 to ensure the normal sliding of the sliding part and the stability of the structure. Overall technical effect: The structure of the milling cone body 303 is optimized, and the performance of the window milling cone 3 under various working conditions is improved.

[0056] In some examples, the first sliding member 308 slides and unidirectionally rotates on the first guide portion 305, and the second sliding member 309 slides and unidirectionally rotates on the second guide portion 306, and the direction of the unidirectional rotation of the first sliding member 308 is opposite to the direction of the unidirectional rotation of the second sliding member 309.

[0057] In the actual working process, for example, when performing window opening operation: when the window opening milling cone 3 is subjected to cutting forces or torques in different directions, the first sliding member 308 and the second sliding member 309 can slide and rotate unidirectionally accordingly according to the force conditions. Since their unidirectional rotation directions are opposite, they can better adapt to complex and changeable working conditions and balance and disperse the force.

[0058] The advantages of this design are: first, the one-way rotation setting increases the freedom of movement of the sliding part, so that it can more flexibly cope with various complex cutting conditions, and improve the adaptability and work efficiency of the window milling cone 3. Second, the opposite one-way rotation direction can effectively balance and offset part of the torque and impact force, reduce the adverse effects on the milling cone body 303, and extend the service life of the window milling cone 3.

[0059] For example, when encountering uneven rock texture or abnormal cutting resistance, the special movement mode of the first sliding member 308 and the second sliding member 309 can avoid local stress concentration and ensure the smooth progress of the window opening operation.

[0060] In terms of technical effects, the stability and reliability of the window milling cone 3 under complex working conditions are significantly improved, and the cutting performance is optimized. Overall working principle: The first sliding member 308 and the second sliding member 309 are used to slide on their respective guide parts and rotate unidirectionally in opposite directions to adapt to and balance the forces during work. Overall technical effect: The working performance and durability of the window milling cone 3 are enhanced through the unique motion design.

[0061] In some examples, the window milling cone 3 also includes a first ratchet pawl assembly 314, which is disposed between the first guide portion 305 and the first sliding member 308; the second ratchet pawl assembly is disposed between the second guide portion 306 and the second sliding member 309; wherein the first ratchet pawl assembly 314 is configured so that the pawl can slide axially along the ratchet wheel, and the second ratchet pawl assembly 315 is also configured so that the pawl can slide axially along the ratchet wheel.

[0062] This design has the following significant advantages: on the one hand, through the setting of the ratchet pawl assembly, the unidirectional rotation direction of the first sliding member 308 and the second sliding member 309 can be accurately controlled to ensure that they move according to the design requirements, thereby effectively realizing the stable and precise operation of the window milling cone 3 under complex working conditions. On the other hand, the special configuration that the pawl can slide along the axial direction of the ratchet wheel enables the ratchet pawl assembly to adaptively adjust its position during the sliding process of the sliding member, so that the first thread segment 301 can be separated from the first thread portion 202, and the second thread portion 203 can be separated from the second thread segment 302 after the window milling cone 3 rotates in the forward and reverse directions, while the effective restriction on the rotation direction can always be maintained. The technical effect brought about is: the reverse double-thread connection structure set at intervals is used to achieve a stable connection when going down the well, and when sealing, the first thread segment 301 can be conveniently disconnected from the first thread portion 202, and the second thread portion 203 can be conveniently disconnected from the second thread segment 302 by operating the window milling cone 3 to cleverly rotate forward and reverse.

[0063] Specifically, when the guide bevel 2 is sent to the sealing position and needs to be sealed, the window milling cone 3 is controlled to rotate forward, and the screw 4 will be cut off first, and the window milling cone 3 continues to rotate forward. Since the first ratchet pawl assembly 314 and the second ratchet pawl assembly 315 have opposite directions of unidirectional rotation, the window milling cone 3 rotates forward, which will cause the first sliding member 308 and the second sliding member 309 to rotate forward while the other remains fixed. The window milling cone 3 rotates in the opposite direction again, which will cause the first sliding member 308 and the second sliding member 309 to rotate while the other remains fixed. The first sliding member 308 and the second sliding member 309 rotate forward and reverse respectively, so that the first thread segment 301 can be separated from the first thread portion 202, and the second thread portion 203 can be separated from the second thread segment 302.

[0064] It should be noted that when the first sliding member 308 rotates forward, the first thread segment 301 and the first thread portion 202 gradually separate, and the second thread portion 203 and the second thread segment 302 remain relatively stationary, which will cause the second sliding member 309 to move relative to the first thread portion 202. Therefore, it is necessary to design the pawl of the second ratchet pawl assembly 315 to be able to slide axially along the ratchet. Similarly, the first ratchet pawl assembly 314 also needs to be designed so that the pawl can slide axially along the ratchet.

[0065] like Figure 6~Figure 9 As shown, in a continuous tubing integrated window opening device, a flow diversion structure 5 is also included. The flow diversion structure 5 is used to provide drilling fluid for the sealing body 1 for sealing, and is also used to provide drilling fluid to rotate the window opening milling cone 3. The flow diversion structure 5 includes a pipe body 501, and the pipe body 501 has a pipe cavity 502. The pipe cavity 502 has a drilling fluid inlet 503 at one end, a drilling fluid straight outlet 504 at the other end, and a drilling fluid bypass port 505 on the side; the sliding pipe 506 has a first guide cavity 507, and the drilling fluid inlet 503 leads to the first guide cavity 507. The sliding pipe 506 also has a bypass blocking portion 508. After the sliding pipe 506 slides, it blocks or cancels the drilling fluid bypass port. 505, so that the first flow guide cavity 507 is connected to or cancels the connection to the drilling fluid bypass port 505; the elastic member 509 acts on the sliding tube 506, providing the sliding tube 506 with a force to slide so that the bypass blocking portion 508 cancels blocking the drilling fluid bypass port 505; the rotating tube 510 is arranged in the tube body 501, and has a second flow guide cavity 511, and the first flow guide cavity 507 is connected to the second flow guide cavity 511; the rotating tube 510 also has a straight-through blocking portion 512, after the rotating tube 510 rotates, the straight-through blocking portion 512 blocks or cancels blocking the drilling fluid straight outlet 504; the sliding tube 506 and the rotating tube 510 are configured so that the sliding tube 506 drives the rotating tube 510 to rotate after sliding.

[0066] In the integrated deflector diversion structure: the pipe body 501 is used as the main structure, the drilling fluid inlet 503 at one end of the pipe cavity 502 receives the drilling fluid, the drilling fluid direct outlet 504 at the other end is used for the direct circulation of the drilling fluid, thereby driving the motor, and the drilling fluid bypass port 505 on the side is used for bypass circulation. The first diversion cavity 507 of the sliding pipe 506 receives the drilling fluid from the drilling fluid inlet 503. When the sliding pipe 506 slides, the bypass stopper 508 blocks or cancels the blocking of the drilling fluid bypass port 505 accordingly, thereby controlling the communication state between the first diversion cavity 507 and the drilling fluid bypass port 505. The elastic member 509 provides a force to make the bypass stopper 508 cancel the blocking of the drilling fluid bypass port 505. The rotating tube 510 is arranged in the pipe body 501, and its second diversion cavity 511 is connected with the first diversion cavity 507. The straight-through blocking portion 512 of the rotating tube 510 blocks or cancels the blocking of the drilling fluid straight outlet 504 by rotating. The sliding tube 506 and the rotating tube 510 cooperate with each other, and the sliding of the sliding tube 506 drives the rotating tube 510 to rotate.

[0067] In practical applications, for example, in oil drilling operations, when bypass circulation of drilling fluid is required, under the action of the elastic member 509 on the sliding tube 506, the bypass stopper 508 stops blocking the drilling fluid bypass port 505, and the straight-through stopper 512 blocks the drilling fluid straight outlet 504, maintaining complete bypass of the drilling fluid. When straight-through circulation is required, the sliding tube 506 is pushed to slide against the force of the elastic member 509 by increasing the pressure of the drilling fluid, so that the bypass stopper 508 blocks the drilling fluid bypass port 505, and at the same time, the sliding tube 506 drives the rotating tube 510 to rotate, so that the straight-through stopper 512 stops blocking the drilling fluid straight outlet 504, achieving complete straight-through of the drilling fluid.

[0068] The advantages of this design are: first, it can accurately control the flow path of the drilling fluid, avoiding the drilling fluid from entering the direct circulation during the bypass circulation, thus improving the accuracy and stability of the drilling operation. Second, the integrated structure reduces the connection and sealing problems between components, reducing the risk of leakage and failure.

[0069] For example, under complex drilling conditions, it can effectively avoid problems such as abnormal rotation of the motor, premature separation of the drill bit and the deflector, and premature sealing of the deflector due to uncontrolled drilling fluid flow, thereby ensuring the smooth progress of drilling operations.

[0070] In terms of technical effects, the control accuracy and reliability of the diverter diversion structure are significantly improved. Overall working principle: Through the sliding of the sliding tube 506 and the rotation of the rotating tube 510, the drilling fluid bypass circulation and the straight-through circulation are accurately switched. Overall technical effect: The diversion control of the drilling fluid is optimized, and the efficiency and safety of oil drilling operations are improved.

[0071] In some examples, one end of the sliding tube 506 close to the drilling fluid inlet 503 has an annular action surface 513 , and the annular action surface 513 is located in the tube cavity 502 .

[0072] In the flow-dividing structure, an annular action surface 513 is provided at one end of the sliding tube 506 close to the drilling fluid inlet 503, and the annular action surface 513 is located in the tube cavity 502. In actual operation, for example, when the drilling fluid enters from the drilling fluid inlet 503, the annular action surface 513 can evenly withstand the pressure of the drilling fluid, thereby pushing the sliding tube 506 to slide more stably.

[0073] The advantages of this design are: first, it ensures that the sliding tube 506 can move smoothly when subjected to drilling fluid pressure, thereby improving the stability and reliability of the diversion structure; second, the annular action surface 513 increases the contact area with the drilling fluid, making the force more uniform and reducing component damage caused by excessive local force.

[0074] For example, in a high-pressure drilling fluid environment, the annular action surface 513 can effectively bear the force to ensure the normal operation of the sliding tube 506 and avoid jamming or failure.

[0075] In terms of technical effects, the response accuracy and stability of the sliding tube 506 to the drilling fluid pressure are significantly improved. Overall working principle: The annular action surface 513 is used to evenly bear the drilling fluid pressure to achieve stable sliding of the sliding tube 506. Overall technical effect: By optimizing the force structure of the sliding tube 506, the performance and reliability of the diverter diversion structure are improved.

[0076] In some examples, the annular active surface 513 is conical, and its diameter gradually decreases from close to the drilling fluid inlet 503 to far away from the drilling fluid inlet 503 .

[0077] In the flow splitting structure, the annular action surface 513 is conical, and its diameter gradually decreases from close to the drilling fluid inlet 503 to far away from the drilling fluid inlet 503. In actual operation, for example, when drilling fluid enters, this conical annular action surface 513 has unique advantages.

[0078] The advantages of this design are: first, the conical shape can play a certain role in guiding the drilling fluid, so that the pressure of the drilling fluid can be more effectively converted into the power to push the sliding tube 506 to slide, thereby improving the energy conversion efficiency. Second, as the diameter gradually decreases, the backflow and turbulence of the drilling fluid on the annular action surface 513 can be reduced, the pressure loss can be reduced, and the movement of the sliding tube 506 can be ensured to be more sensitive and accurate.

[0079] For example, under complex drilling conditions, the pressure and flow of the drilling fluid may change, and the conical annular action surface 513 can better adapt to these changes and ensure the stable and reliable operation of the sliding tube 506.

[0080] In terms of technical effects, the response sensitivity and energy utilization efficiency of the sliding tube 506 to the drilling fluid pressure are improved. Overall working principle: Through the flow diversion and pressure optimization of the conical annular action surface 513, the sliding tube 506 can slide efficiently and sensitively. Overall technical effect: The structure of the annular action surface 513 is optimized, and the performance and working reliability of the diverter diversion structure are further improved.

[0081] In some examples, the rotating tube 510 has a sliding portion 514, and the tube wall of the rotating tube 510 has a guide groove 515. The sliding portion 514 is slidably arranged in the guide groove 515. The sliding portion 514 and the guide groove 515 are used to drive the rotating tube 510 to rotate after the sliding tube 506 slides.

[0082] In the integrated deflector flow diversion structure, the rotating tube 510 has a sliding portion 514 , a tube wall of which is provided with a guide groove 515 , and the sliding portion 514 is slidably disposed in the guide groove 515 .

[0083] In actual operation, when the sliding tube 506 slides, for example, when performing a drilling fluid diversion switching operation, the sliding tube 506 contacts the sliding portion 514 and interacts with each other.

[0084] The advantages of this design are: first, through the cooperation of the sliding part 514 and the guide groove 515, the linear sliding of the sliding tube 506 can be accurately converted into the rotation of the rotating tube 510, ensuring the accuracy and reliability of the action. Second, the guide groove 515 has a limiting and guiding effect on the movement of the sliding part 514, avoiding deviation or jamming of the rotating tube 510 during the rotation process, and can better ensure that the straight-through loop is well disconnected. Compared with the simple sliding method to disconnect the straight-through loop, the sliding and rotating form improves the isolation effect of the straight-through loop being closed.

[0085] For example, in a working scenario where diversion switching is frequently performed, this reliable transmission structure can ensure that the rotating tube 510 can be accurately rotated in each operation, thereby achieving accurate control of the flow direction of the drilling fluid.

[0086] In terms of technical effects, the accuracy and stability of the sliding tube 506 driving the rotating tube 510 to rotate are significantly improved. Overall working principle: The sliding of the sliding part 514 in the guide groove 515 is used to realize the transmission from the sliding of the sliding tube 506 to the rotation of the rotating tube 510. Overall technical effect: Through the ingenious transmission structure design, the motion control performance of the diagonal guide diversion structure is optimized.

[0087] In some examples, the guide groove 515 has a vertical sliding section 516 and a torsion section 517 , the vertical sliding section 516 and the torsion section 517 are connected, and the torsion section 517 is spiral.

[0088] In the diversion structure, the guide groove 515 has a vertical sliding section 516 and a torsion section 517 , and the torsion section 517 is spiral-shaped, and the vertical sliding section 516 and the torsion section 517 are connected.

[0089] In the actual working process, for example, when the sliding tube 506 slides: at first, the sliding part 514 slides in the vertical sliding section 516 to achieve linear motion. When the sliding part 514 enters the torsion section 517 from the vertical sliding section 516, the linear motion of the sliding part 514 is converted into the torsion motion of the rotating tube 510 because the torsion section 517 is spiral.

[0090] The advantages of this design are: first, the vertical sliding section 516 can provide an initial linear guide to ensure the stable sliding of the sliding tube 506 in the initial stage, preparing for the subsequent rotation. Second, the spiral torsion section 517 can achieve a smooth and continuous rotation conversion, avoiding sudden rotation shock, and improving the stability and reliability of the structure.

[0091] For example, in frequent drilling fluid diversion and switching operations, the segmented and specially shaped guide groove 515 can ensure that the rotating tube 510 rotates accurately and smoothly, reducing the wear and failure risks of components.

[0092] In terms of technical effects, the process of the sliding tube 506 driving the rotating tube 510 to rotate is significantly optimized, and the stability and accuracy of the action are improved. Overall working principle: Through the sequential action of the vertical sliding section 516 and the spiral torsion section 517, the conversion from the sliding of the sliding tube 506 to the smooth rotation of the rotating tube 510 is realized. Overall technical effect: Through the unique structural design of the guide groove 515, the working performance and reliability of the diverter diversion structure are improved.

[0093] In some examples, the drilling fluid straight outlet 504 is circular, and its axis is offset from the axis of the rotating tube 510 .

[0094] In the diversion structure, the drilling fluid direct outlet 504 is circular, and its axis is misaligned with the axis of the rotating tube 510. In actual operation, for example, in the process of controlling the direct outflow of drilling fluid: this axis misalignment design has certain advantages. When the rotating tube 510 rotates to make the direct blocking portion 512 block or cancel the blocking of the drilling fluid direct outlet 504, due to the axis misalignment, the outflow timing and flow rate of the drilling fluid can be more accurately controlled.

[0095] The advantages of this design are: first, through the axis misalignment, more precise flow regulation can be achieved to meet the needs of different drilling conditions. Second, the wear between the straight-through baffle 512 and the drilling fluid straight outlet 504 is reduced, extending the service life of the components. For example, when it is necessary to accurately control the drilling fluid straight flow rate, the axis misalignment design can provide more accurate control to avoid excessive or insufficient flow from adversely affecting the drilling operation.

[0096] In terms of technical effects, the control accuracy of the drilling fluid direct flow rate and the durability of the components are significantly improved. Overall working principle: The misalignment of the drilling fluid direct outlet 504 and the axis of the rotating tube 510 is used to achieve precise control of the drilling fluid direct outflow. Overall technical effect: Through the clever axis layout, the regulation performance of the diverter diversion structure on the drilling fluid direct flow rate is optimized.

[0097] In some examples, the drilling fluid straight outlet 504 further has a flared portion 518 , which is located at the lower end of the drilling fluid straight outlet 504 .

[0098] In the diversion structure, the drilling fluid straight outlet 504 also has a flared portion 518, and the flared portion 518 is located at the lower end of the drilling fluid straight outlet 504. In actual working conditions, for example, when the drilling fluid flows out of the drilling fluid straight outlet 504: the existence of the flared portion 518 has a significant effect. It can increase the cross-sectional area of ​​the drilling fluid outflow, thereby reducing the resistance during outflow, so that the drilling fluid can be discharged more smoothly.

[0099] The advantages of this design are: first, it reduces the pressure loss of drilling fluid at the outlet and improves the discharge efficiency of drilling fluid. Second, it reduces the backflow and turbulence that may be caused by excessive outlet resistance, ensuring the stability of drilling fluid flow. For example, in high-flow drilling operations, the expansion portion 518 can effectively avoid the accumulation and blockage of drilling fluid at the straight outlet, ensuring the smooth progress of the drilling process.

[0100] In terms of technical effects, the fluidity and stability of the drilling fluid flowing out of the straight outlet are significantly improved. Overall working principle: The expansion portion 518 increases the outflow cross-sectional area, reduces resistance, and realizes smooth discharge of the drilling fluid from the drilling fluid straight outlet 504. Overall technical effect: By setting the expansion portion 518 at the drilling fluid straight outlet 504, the discharge performance of the drilling fluid is optimized, and the efficiency and reliability of the drilling operation are improved.

[0101] In some examples, the sliding tube 506 further has a communication port 519 , which is located at one side of the bypass stopper 508 . The communication port 519 is used to connect or cancel the drilling fluid bypass port 505 .

[0102] In actual work, for example, when performing a drilling fluid diversion operation: when the sliding tube 506 slides and the bypass baffle 508 stops blocking the drilling fluid bypass port 505, the connecting port 519 is connected to the drilling fluid bypass port 505, and the drilling fluid is able to flow out through the bypass port 505; and when the sliding tube 506 slides so that the bypass baffle 508 blocks the drilling fluid bypass port 505, the connecting port 519 also correspondingly stops being connected to the drilling fluid bypass port 505.

[0103] The advantages of this design are: first, the flow rate and timing of the drilling fluid bypass can be more accurately controlled by setting the connecting port 519. Second, the sliding tube 506 can more effectively open and close the drilling fluid bypass during the sliding process, thereby improving the accuracy and reliability of the diversion operation.

[0104] For example, under working conditions with high requirements for drilling fluid diversion, the connecting port 519 can ensure the stability and controllability of the bypass flow, avoiding unnecessary fluctuations and errors. In terms of technical effects, the control accuracy and stability of the drilling fluid bypass operation are significantly improved. Overall working principle: By sliding the sliding tube 506, the connecting port 519 is connected or disconnected with the drilling fluid bypass port 505, thereby controlling the bypass of the drilling fluid. Overall technical effect: Through the design of the connecting port 519, the control performance of the diverter diversion structure on the drilling fluid bypass is optimized.

[0105] In some examples, the communication port 519 and the drilling fluid bypass port 505 are arranged in a plurality of circles.

[0106] In the actual working process, for example, when performing drilling fluid bypass operation: a plurality of circumferentially arranged communication ports 519 and drilling fluid bypass ports 505 can work simultaneously to evenly distribute the flow of drilling fluid and reduce the phenomenon of local pressure concentration and uneven flow.

[0107] The advantages of this design are: first, it increases the number of drilling fluid bypass channels, improves bypass efficiency and flow control accuracy. Second, the circular arrangement makes the force more uniform, reducing the wear and deformation of components caused by uneven local force.

[0108] For example, in high-flow, long-duration drilling operations, multiple circumferentially arranged ports can effectively share the flow, reduce the operating pressure of each port, and extend the service life of the components.

[0109] In terms of technical effects, the flow uniformity of the drilling fluid bypass and the durability of the structure are significantly improved. Overall working principle: through the coordinated work of multiple circumferentially arranged connecting ports 519 and the drilling fluid bypass ports 505, uniform and efficient drilling fluid bypass is achieved. Overall technical effect: The bypass performance and reliability of the diverter diversion structure are optimized by utilizing the design of multiple circumferentially arranged ports.
