Description

Technical Field

[0001] This invention relates to the fields of geothermal and oil and gas drilling, and in particular to an intelligent crawlable centralizer and drilling tool. Background Technology

[0002] Against the backdrop of economic downturn, accelerating and improving drilling efficiency has become a crucial means for efficient oil and gas exploration and development. Drill string assemblies that can be flexibly adjusted to meet the drilling needs of different formations are key to achieving this. Among these, the centralizer, as the most commonly used drilling tool in the assembly, is primarily used to adjust the assembly's deflection or directional build-up capabilities. This adjustment is typically achieved by changing the distance between the centralizer and the drill bit. However, current technology only allows this adjustment to be accomplished by tripping the drill string and changing the assembly, which is not only time-consuming and labor-intensive but also reduces production efficiency.

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0025] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0026] Based on the above objectives, a first aspect of the present invention provides an intelligent crawlable uprighting device. For example... Figure 1 and Figure 2 As shown, the intelligent crawlable straightener includes: a body 1, with an axially extending crawling track 11 on the outer surface of the body 1; a straightening block 2, which is sleeved around the outer surface of the body 1 and can crawl along the crawling track 11; a power module 3, which is fixed to the straightening block 2 and is used to drive the straightening block 2 to crawl along the crawling track 11; a braking module 4, which is fixed to the straightening block 2 and can be movably engaged with the crawling track 11 to lock the straightening block 2 to the body 1; and a controller 32, which is communicatively connected to the power module 3 and the braking module 4 and is used to control the crawling of the straightening block 2.

[0027] In some embodiments, the crawling track 11 is configured as crawling teeth, the power module 3 includes a first screw 31 that meshes with the crawling teeth and a first motor 33 for driving the first screw 31 to rotate, and the controller 32 is communicatively connected to the first motor 33 for controlling the rotation of the first motor 33 to drive the first screw 31 to rotate, thereby driving the straightening block 2 to crawl along the crawling teeth.

[0028] In some embodiments, the braking module 4 includes: a locking plate 41 having a locked position and an unlocked position; in the locked position, the locking plate 41 engages with the crawling teeth to prevent the straightening block 2 from crawling along the crawling teeth; in the unlocked position, the locking plate 41 disengages from the crawling teeth, allowing the straightening block 2 to crawl along the crawling teeth; a drive mechanism connected to the locking plate 41 for driving the locking plate 41 to move between the locked position and the unlocked position; and a controller 32 communicatively connected to the drive mechanism for controlling the movement of the locking plate 41.

[0029] In some embodiments, the locking plate 41 is provided with crawling teeth, and the driving mechanism includes a second screw 43 that meshes with the crawling teeth and a second motor 42 for driving the second screw 43 to rotate. The controller 32 is communicatively connected to the second motor 42 and is used to control the rotation of the second motor 42 to drive the second screw 43 to rotate, thereby driving the locking plate 41 to move.

[0030] In some implementations, the controller 32 is configured to: acquire a voltage signal within the body 1, determine displacement data based on the voltage signal, and control the crawling of the straightening block 2 based on the displacement data.

[0031] In some implementations, controlling the crawling of the straightening block 2 based on displacement data includes: controlling the first motor 33 to rotate forward or reverse based on displacement data to drive the straightening block 2 to crawl upward or downward along the crawling teeth.

[0032] In some embodiments, a battery is also included to power the power module 3, the braking module 4, and the controller 32.

[0033] In some embodiments, the bottom of the locking plate 41 is provided with a locking plate engaging part 49 and a square hole 45 is provided on the inner side, and crawling teeth are provided on one side of the square hole 45.

[0034] In some embodiments, a locking plate fixing block 46 is also included, which is fixed to the straightening block 2 to restrict the movement of the locking plate 41.

[0035] In some embodiments, a spring 47 is also included, one end of which is engaged with the locking plate 41 and the other end of which is engaged with the locking plate fixing block 46, for controlling the locking plate 41 and the second screw 43 to be in a locked state under the action of elastic force.

[0036] In some embodiments, the body 1 further includes a first ball groove 12 for mounting balls to reduce resistance when the straightening block 2 moves back and forth.

[0037] In some embodiments, the straightening block 2 further includes a second ball groove 21 connected to the first ball groove 12 via ball bearings.

[0038] In some embodiments, a protective shell 5 is also included, which is fixed to the straightening block 2 and is used to protect the power module 3 and the braking module 4.

[0039] In some embodiments, a voltage monitoring plate and a detection magnetic plate 6 are also included. The voltage monitoring plate and the detection magnetic plate 6 are installed inside the body 1. The detection magnetic plate is used to generate a magnetic field to change the voltage signal under the influence of displacement. The voltage monitoring plate is used to monitor the voltage signal. The controller 32 is communicatively connected to the voltage monitoring plate to receive the voltage signal from it.

[0040] In some embodiments, the intelligent crawlable centralizer includes a body 1, a centralizing block 2, a power module 3, a braking module 4, a protective shell 5, a voltage monitoring plate, and a detection magnetic plate, which are connected together by pins or threads to form a centralizer that can arbitrarily adjust the distance between the centralizer and the drill bit by changing the displacement. This avoids the problem of tripping the drill bit due to the distance between the centralizer and the drill bit not meeting the requirements, and can also greatly increase the length of the composite drilling section, improve trajectory control efficiency, and production timeliness.

[0041] In some implementations, such as Figure 2 and Figure 3As shown, the top and bottom of the main body 1 are respectively provided with threads for connecting the drill bit. Specifically, the top of the main body 1 has threads on its inner surface for connecting with the upper drill bit, and the bottom of the main body 1 has threads on its outer surface for connecting with the bottom drill bit. The outer side of the main body 1 is axially spaced with a first ball groove 12 and a crawling track 11. Specifically, the outer surface of the main body 1 is provided with a toothed crawling track 11 for cooperating with the power module 3 to push the centralizing block 2 to move axially. The outer surface of the main body 1 is also provided with a first ball groove 12 for installing balls to reduce the resistance of the centralizing block 2's forward and backward movement. Figure 4 As shown, the main body 1 has a voltage monitoring chip mounting slot 13 and a magnetic detection chip mounting slot 14 spaced apart inside for mounting the voltage monitoring chip and the magnetic detection chip. During installation, the line connecting the two voltage monitoring chips is perpendicular to the line connecting the two magnetic detection chips.

[0042] In some implementations, such as Figure 1 , Figure 2 and Figure 5 As shown, the straightening block 2 is fitted onto the main body 1, with a straightening rib 26 on its outer side. The left and right sides have a first mounting groove 22, a second mounting groove 23, a third mounting groove 24, and a fourth mounting groove 25 for mounting the power module 3 and the braking module 4, respectively. Inside the straightening block 2, a second ball groove 21 is formed that engages with the first ball groove 12 via ball bearings. Two first pin holes 27 are formed on each of the left and right sides of the straightening block 2 for connecting to the protective shell 5 via pins.

[0043] In some implementations, such as Figure 6 As shown, the power module 3 is cylindrical in shape. The upper part has a first fixing pin groove 34, which engages with the fourth mounting groove 25 of the straightening block 2 via a pin to fix the power module 3 to the straightening block 2. The middle part houses the controller 32, battery, and first motor 33, while the bottom has a first screw 31. The first motor 33 is a stepper motor used to drive the first screw 31 to rotate. The first screw 31 engages with the first crawling teeth 11 on the body 1, and under the drive of the first motor 33, pushes the straightening block 2 to crawl upwards or downwards along the axis of the body 1. Specifically, the external thread of the first screw 31 forms a helical engagement with the teeth of the crawling track 11. Each rotation of the first screw 31 moves a corresponding distance along the crawling track 11 according to the screw pitch, converting the rotational motion of the first screw 31 into linear motion along the axis of the body 1, thus causing the straightening block 2 to crawl along the axis of the body 1.

[0044] In some implementations, such as Figure 7-9As shown, the braking module 4 includes a drive mechanism, a locking plate 41, a locking plate fixing block 46, and a spring 47. Locking plate limiting keys 48 are provided on both sides of the locking plate 41, which cooperate with the second mounting groove 23 on the straightening block 2, allowing the locking plate 41 to move only back and forth relative to the body 1, i.e., between the locked and unlocked positions. A square hole 44 is provided on the inner side of the locking plate 41, and crawling teeth are provided on one side of the square hole 44. A locking plate engaging part 49 is provided at the bottom of the locking plate 41 for engaging with the crawling track 11, which can stably lock the position of the straightening block 2 on the body 1. The drive mechanism is cylindrical in shape, with a second fixing pin groove 410 at the bottom, which cooperates with the first mounting groove 22 of the straightening block 2 to fix the braking module 4 onto the straightening block 2. The drive mechanism has a second motor 42 in the middle and a second screw 43 at the top. The second motor 42 is a stepper motor used to drive the second screw 43 to rotate. The second screw 43 is used to engage with the crawling teeth on the locking plate 41, pushing the locking plate 41 between the locked and unlocked positions under the drive of the second motor 42. The locking plate fixing block 46 has third pin holes 411 on both sides, which are used to fix the locking plate fixing block 46 to the straightening block 2 by engaging with the second pin holes 28 on the straightening block 2. The locking plate fixing block 46 has a spring limit key 412 on its inner side, which is used to limit the movement of the spring 47. One end of the spring 47 is embedded in the spring limit key 412, and the other end is embedded in the locking plate spring mounting groove 45, which is used to keep the locking plate 41 and the second screw 43 in a stable locked state under the action of elastic force. Specifically, when the locking plate 41 moves to the locking plate engaging part 49 and is firmly engaged with the teeth of the crawling track 11, the locking plate 41 is in the locked position. When the locking plate 41 moves to the locking plate engaging part 49 and is not engaged with the teeth of the crawling track 11, the locking plate 41 is in the unlocked position.

[0045] In some implementations, such as Figure 10 As shown, the protective shell 5 is semi-cylindrical, with third pin holes 51 on both sides, which are used to fix the protective shell 5 to the straightening block 2 by means of pin engagement with the first pin hole 27 on the straightening block 2, so as to protect the power module 3 and the braking module 4.

[0046] In some implementations, such as Figure 11As shown, the voltage monitoring plate and the magnetic detection plate are arc-shaped. Two magnetic detection plates are used to generate a magnetic field to change the voltage signal when affected by displacement. Two voltage monitoring plates are used to monitor the voltage, and the voltage monitoring plates are installed at intervals. The controller 32 is communicatively connected to the voltage monitoring plates to receive voltage signals from them. The controller 32 can determine the displacement data by filtering and calculating the received voltage signals, and then determine the displacement change. Based on the displacement change, the controller controls the rotation direction of the first motor 33 and the second motor 42. For example, when the displacement changes to be greater than a first threshold, the controller controls the first motor 33 and the second motor 42 to rotate forward to drive the straightening block 2 to crawl upward along the axis of the body 1. When the displacement changes to be greater than a second threshold, the controller controls the first motor 33 and the second motor 42 to rotate in reverse to drive the straightening block 2 to crawl downward along the axis of the body 1. The first threshold and the second threshold can be set according to the actual application situation, and are not specifically limited here.

[0047] In some embodiments, the installation steps of the intelligent crawlable uprighting device of the present invention are as follows: 1. Install the voltage monitoring chip and the detection magnetic chip into the voltage monitoring chip mounting slot 13 and the detection magnetic chip mounting slot 14 using screws; 2. Install the straightening block 2 onto the main body 1; 3. Write the program into controller 32; 4. Install the power module 3 and the braking module 4 into the designated mounting slots in the straightening block 2, and fix them with the locking plate, the pressure block 46 and the pins. 5. Install the protective shell 5 onto the straightening block 2.

[0048] In one example, the above procedure is as follows: Figure 12-15 As shown, the circuit diagram of the intelligent crawlable straightener is as follows: Figure 16 As shown. The intelligent crawlable centralizer of the present invention can monitor changes in displacement data in real time by monitoring changes in voltage within the body 1. These changes in displacement data are used to input signals to the controller 32, which then controls the first motor 33 and the second motor 42 to rotate forward or backward, driving the centralizer 2 to crawl on the body 1 to adjust the distance between the centralizer and the drill bit. The actions between the first motor 33 and the second motor 42 can be controlled by a delay time (DelayMs) to ensure that the next motor operates only after the previous motor has completed its action, avoiding conflict or damage to mechanical components caused by simultaneous operation of the two motors. The delay time can be set according to the actual application.

[0049] The present invention also proposes a drilling tool, including the above-mentioned intelligent crawlable centralizer.

[0050] The present invention has at least the following beneficial technical effects: (1) By setting the power module 3 and the braking module 4, the crawling position of the straightening block 2 on the body 1 can be precisely controlled, thereby flexibly adjusting the distance between the straightening block 2 and the drill bit to meet the drilling needs of different formations, improve the trajectory control accuracy, and optimize the trajectory control efficiency. (2) The combined design of power module 3 and braking module 4 enables the adjustment and locking process of centering block 2 to be operated in one piece, simplifying operation, improving efficiency, avoiding the cumbersome process of adjusting distance by changing drill string combination during tripping in traditional technology, reducing non-productive time, and greatly improving drilling operation efficiency. (3) The locking plate 41 in the braking module 4 and the interlocking design of the crawling teeth can stably lock the position of the centering block 2, ensuring that the centering block 2 will not slide unexpectedly during the drilling process, thus improving the safety and reliability of the equipment and helping to achieve efficient drilling operations.
