Detailed Implementation

[0018] 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.

[0019] 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.

[0020] To improve cementing quality and simplify the construction process, this invention proposes an embodiment of a wirelessly triggered electromagnetic vibration cementing tool, such as... Figure 1 As shown, its structure includes: a housing 5, which comprises a vibrating housing 5-1 disposed on the outer layer and a protective housing 5-2 disposed on the inner layer. The protective housing 5-2 and the vibrating housing 5-1 are rigidly connected by a vibration transmission part 5-3, and a mud channel 5-4 is formed between the vibrating housing 5-1 and the protective housing 5-2; an identification control module 9, an electromagnetic vibration module 10, and a power supply module 11 disposed inside the protective housing. The identification control module 9 is used to receive wireless signals, identify and obtain configuration information to generate control signals; the electromagnetic vibration module 10 is used to trigger the start based on the control signals, and generate vibrations with controllable frequency and amplitude according to the control signals, which resonate with the vibrating housing 5-1 through the vibration transmission part 5-3; the power supply module 11 is electrically connected to the identification control module 9 and the electromagnetic vibration module 10 respectively.

[0021] In an optional embodiment, both the vibrating housing 5-1 and the protective housing 5-2 are cylindrical. The outer diameter of the protective housing 5-2 is smaller than the inner diameter of the vibrating housing 5-1, and it is disposed inside the vibrating housing 5-1. The protective housing 5-2 is also provided with a support part 5-2-1, which is annular and has a guide hole for abutting against the inner wall of the vibrating housing 5-1 to ensure that there is a gap between the vibrating housing 5-1 and the protective housing 5-2, which serves as a mud channel to facilitate the injection of cement slurry into the well bottom. In addition, the vibration transmission part 5-3 can be a part of the protective housing 5-2 and is disposed at the bottom of the electromagnetic vibration module 10 to achieve rigid contact with the vibrating housing 5-1, so that the vibration can be transmitted from the vibration transmission part 5-3 to the vibrating housing 5-1.

[0022] In this embodiment, the present invention utilizes an electromagnetic vibration module to generate vibrations with controllable frequency and amplitude to resonate with the vibration housing 5-1, thereby making the vibration propagate a longer distance along the vibration housing 5-1 and the vibration more obvious, thus ensuring the cementing effect. Furthermore, the cementing tool of the present invention is self-powered and uses wireless signal triggering, eliminating the need to run cables into the well, which can greatly simplify the construction process and improve construction efficiency.

[0023] In one embodiment, the protective housing includes three separable sections: upper, middle, and lower. The three sections are connected by a plug-in connection. The identification and control module 9 is located inside the upper section, the power supply module 11 is located inside the middle section, and the electromagnetic vibration module 10 is located inside the lower section.

[0024] In this embodiment, the segmented design is intended to facilitate the installation of corresponding hardware modules inside the protective housing 5-2; the power supply module 11 located in the middle section of the protective housing 5-2 facilitates the supply of power to the identification control module 9 and the electromagnetic vibration module 10 at its upper and lower ends to reduce wiring length.

[0025] In an optional embodiment, to facilitate vibration transmission, the lower housing with the electromagnetic vibration module 10 is fitted over the middle housing with the power supply module 11, and a ring block 5-4 is provided between them. The outer surface of the lower housing is provided with the aforementioned vibration transmission part 5-3 for rigid contact with the vibration housing 5-1. Thus, when the electromagnetic vibration module vibrates, the lower housing will act as a vibration chamber to transmit vibration to the vibration housing 5-1, and the impact on other segments can be minimized.

[0026] In one embodiment, the housing of the wirelessly triggered electromagnetic vibration cementing tool of the present invention further includes: an upper connector 3, connected to the upper part of the upper housing, for connecting to an external mud pipe; a flow guide cap 7, disposed below the upper connector 3, for sealing the top of the protective housing 5-2, and having flow guide holes 7-1 on both sides, the flow guide holes 7-1 for guiding mud to the mud channel between the vibration housing 5-1 and the protective housing 5-2; and a lower connector 13, connected to the lower part of the lower housing, for sealing the bottom of the protective housing 5-2 and guiding mud to the bottom of the well so that the mud flows back from the inside of the vibration housing 5-1 to the well wall and between the vibration housing 5-1.

[0027] Specifically, during the construction process, a well needs to be drilled first, and then the cementing tool of the present invention is lowered into the well. Then, cement slurry is injected into the cementing tool through a mud pipe connected to the cementing tool of the present invention. The cement slurry will reach the bottom of the well through the mud channel between the vibrating shell 5-1 and the protective shell 5-2, and then flow back from the bottom of the well to the well outside the vibrating shell 5-1, filling the space between the well wall and the vibrating shell 5-1. This bottom-to-top backflow method helps to ensure that the cement slurry evenly covers the well wall and reduces the generation of air bubbles.

[0028] In one embodiment, the power supply module 11 includes: a battery fixing bracket 11-1, a battery 11-2, and an adjustment shim 11-3. The top of the battery 11-2 is fixed to the bottom of the current guide cap 7 by the battery fixing bracket 11-1. The bottom of the battery 11-2 is provided with an adjustment shim 11-3, which abuts against the top of the electromagnetic vibration module 10 to support and dampen vibration.

[0029] In one embodiment, the identification control module 9 includes: a signal receiving antenna 9-1, a signal reader 9-2, and a first controller 9-3. The signal reader 9-2 is electrically connected to both the signal receiving antenna 9-1 and the first controller 9-3. The signal reader 9-2 identifies the wireless signal captured by the signal receiving antenna, modulates and demodulates the identified wireless signal into configuration information, and forwards it to the first controller 9-3. The first controller 9-3 has multiple preset trigger modes for acquiring the configuration information and selecting and configuring the corresponding trigger mode according to the configuration information to generate a control signal. The cementing tool of this invention also includes a chip holder 8, which is fixed inside the upper section of the protective housing. The signal reader 9-2 and the first controller 9-3 are fixed to the surface of the chip holder 8.

[0030] In an optional embodiment, the signal reader 9-2 is a radio frequency identification (RFID) unit, used to receive radio frequency signals and identify the user. When the radio frequency signal identification is successful, the configuration information in the radio frequency signal is obtained, and the vibration initiation mode is selected and parameters are configured according to the configuration information. In some embodiments, the first controller 9-3 has multiple preset trigger modes, including: (1) The controller is set to a timed trigger mode, and the trigger time (year, month, day, hour, minute, second) can be set. When the time arrives, the first controller 9-3 is triggered and starts working according to the set time. (2) The controller is set to a delay trigger mode, and the delay time for triggering can be set. When the countdown time is reached, the first controller 9-3 is triggered and starts to work according to the settings; (3) Configure a pressure sensor for the first controller 9-3. Set the pressure trigger mode of the controller and set the trigger pressure. When the specified pressure is reached, the first controller 9-3 is triggered and starts to work according to the setting.

[0031] In one embodiment, see Figure 2 The electromagnetic vibration module 10 includes: a thyristor voltage regulator 10-1, electrically connected to the power supply module 11, used to transform the DC output of the power supply module 11; an inverter 10-2, electrically connected to the thyristor voltage regulator 10-1, used to convert the transformed DC power into AC power; and an electromagnetic vibration assembly, electrically connected to the inverter 10-2, used to generate vibration driven by AC power and resonate with the vibration housing 5-1 through the vibration transmission part 5-3. The electromagnetic vibration assembly includes: a base 10-3, an electromagnet 10-4, a spring 10-5, and a vibrating mass block 10-6. The base 10-1 is fixedly connected to the side wall of the vibration chamber (i.e., the lower protective housing). The electromagnet 10-4 is fixed on the base 10-1 and electrically connected to the inverter 10-2. The vibrating mass block 10-6 is located directly above the electromagnet 10-4 and connected to the base by the spring 10-5. It should be noted that, since the electromagnetic vibration assembly is fixedly mounted on the side wall of the protective housing 5-2 in this embodiment, when describing the structural composition of the electromagnetic vibration assembly, as shown below... Figure 2 As shown, the direction with the base on the left is downward, and the direction away from the base on the right is upward.

[0032] Specifically, the main body of the electromagnetic vibration component in this embodiment is a mechanical vibration system. Its natural frequency is only related to the shape, mass, and material properties of the vibrating mass block 10-6, and is independent of the frequency of the magnetic field direction change generated by the electromagnet 10-4. When the frequency of the magnetic field direction change generated by the electromagnet 10-4 is the same as the natural frequency of the vibrating mass block 10-6, the two will resonate. At this time, the electromagnet 10-4 can make the vibrating mass block 10-6 generate the maximum amplitude with minimal power loss, thereby improving the vibration effect. In addition, since this invention also requires the electromagnetic vibration component to resonate with the vibrating shell 5-1, it is necessary to calculate its resonance frequency in advance based on the length of the vibrating shell 5-1, thereby determining the natural frequency of the electromagnetic vibration component and selecting a suitable vibrating mass block 10-6.

[0033] In one embodiment, the electromagnetic vibration assembly of the present invention further includes: an adjustment mass block 10-7, which is detachably and fixedly connected to the vibration mass block 1-6, for adjusting the natural frequency of the electromagnetic vibration assembly. In this embodiment, the adjustment mass block 10-7 can adapt to changes in the length of the vibration housing 5-1, thereby ensuring optimal resonance with the vibration housing.

[0034] In this embodiment, the formula for calculating the natural frequency of the electromagnetic vibration component is:

[0035] Where m = m1 + m2, m1 is the mass of vibrating mass block 1-6, and m2 is the mass of adjusting mass block 1-7. By increasing the mass or number of adjusting mass blocks 1-7, the natural frequency of the electromagnetic vibration component can be changed and adjusted until the vibration frequency reaches the resonance band of the vibration module, thus achieving amplitude amplification with relatively low power. The formula for calculating the excitation force of electromagnetic vibration is:

[0036] in, The number of turns of the DC coil. The number of turns of the AC coil. It is direct current. For alternating current, The permeability of free space, The cross-sectional area of ​​the iron core end face is... The total magnetic reluctance is shown. It can be seen that changing the voltage value can change the excitation force of the electromagnetic vibration module. The voltage value can be adjusted by the thyristor voltage regulator 10-1 to adjust the amplitude of the cementing tool, while the excitation frequency can be controlled by the frequency converter 10-9.

[0037] In one embodiment, the electromagnetic vibration assembly of the present invention further includes a servo motor 10-8, the main body of which is fixedly connected to the vibrating mass block 10-6, connected to the rotating shaft of the adjusting mass block 10-7, and electrically connected to the first controller 9-3, for adjusting the rotation angle of the adjusting mass block 10-7 according to the control signal to change the natural frequency of the electromagnetic vibration assembly.

[0038] Specifically, in this embodiment, the rotation angle of the adjustment mass 10-7 is controlled by the servo motor 10-8 to change the overall shape and center of gravity of the vibrating mass 10-6 and the adjustment mass 10-7, thereby changing the natural frequency jointly determined by them. This embodiment can achieve fine-tuning of the natural frequency of the electromagnetic vibration component through control signals, thereby achieving the best resonance effect.

[0039] In an optional embodiment, a vibration sensor (not shown) is configured for the first controller 9-3. The vibration sensor is fixed on the vibrating mass block 10-6 or built into the servo motor 10-8 and electrically connected to the first controller 9-3. The first controller 9-3 can control the rotation and adjustment of the mass block 10-7 according to a preset program, thereby determining the angle of the mass block 10-7 when the vibration is at its maximum and maintaining this angle to achieve the best resonance effect. This embodiment can adaptively adjust the natural frequency of the electromagnetic vibration component and resonate with the vibration housing 5-1, thereby allowing for certain errors in the length and wall thickness of the vibration housing 5-1.

[0040] In one embodiment, the electromagnetic vibration module of the present invention further includes a frequency converter 10-9, which is electrically connected to the inverter 10-2 and the first controller 9-3, respectively, and is used to convert the AC power according to the control signal to make the electromagnetic vibration component resonate. The purpose of adding the frequency converter 10-9 in this embodiment is to adapt to changes in the natural frequency of the electromagnetic vibration component, thereby achieving maximum amplitude of the vibrating mass block 10-6 and the adjusting mass block 10-7 with minimal power loss, thus improving the vibration effect.

[0041] In one embodiment, since the cementing tool of the present invention operates deep underground, considering the interference from metal and liquid downhole, a second aspect of the present invention also proposes a cementing plug for use after the cementing tool is lowered into the well. This plug communicates wirelessly with the cementing tool via a low-frequency radio frequency identification (RFI) signal to trigger its operation. See also... Figure 3 The structure of the cementing plug in this embodiment includes: a main body 1, which is cylindrical and hollow inside, with multiple segmented annular scrapers 1-1 arranged along the axial direction on the outside; and a signal transmitting module 2, which is located inside the main body 1 and transmits a wireless signal with identification information according to a preset configuration after startup to communicate with the corresponding identification control module 9 and trigger the start of the wireless trigger electromagnetic vibration cementing tool.

[0042] In this embodiment, the annular scraper 1-1 of the cementing plug is inclined and faces the top of the plug. This design can assist in scraping mud from the mud delivery pipeline during the falling process and, after falling, it can be embedded with the upper connector 3 at the top of the cementing tool to form a multi-layer seal, ensuring the stable operation of the subsequent cementing tool.

[0043] In one embodiment, to achieve better fitting with the cementing plug, a plug seat 4 is provided between the upper connector 3 and the vibrating housing 5-1. The plug seat 4 has a groove design that conforms to the shape of the cementing plug 1. Furthermore, to mitigate the impact of the cementing plug falling and to achieve better sealing, a washer 6 is provided between the plug seat 4 and the vibrating housing 5-1; similarly, an O-ring 12 is also provided between the connector 13 and the vibrating housing 5-1.

[0044] In one implementation, please refer to Figure 4 The signal transmitting module 2 further includes: a signal transmitting module housing 2-1, a battery 2-2, a second controller 2-3, a fixing bracket 2-4, a signal transmitting antenna 2-5, and a lower end cover 2-6. The signal transmitting antenna 2-5 is electrically connected to the second controller 2-3, and the battery 2-2 is also electrically connected to the second controller 2-3. The second controller 2-3 may optionally be a radio frequency identification (RFID) module.
