Description

Technical Field

[0001] The present application belongs to the field of mine safety management technology, and specifically relates to a complete set of fracturing equipment equipped with continuous tubing. Background Art

[0002] During the mechanized, comprehensive mining process in coal mines, rock bursts pose a significant threat to mining safety. Therefore, directional hydraulic fracturing is currently being used to mitigate or even address the negative impacts of rock bursts. In current real-time directional hydraulic fracturing, a drill rig is typically used to complete directional drilling. Afterwards, individual fracturing strings are connected and pushed into the wellbore using the directional drill. Finally, a water injection pump is used to pressurize and expand the fractures, completing the fracturing operation within the entire hole.

[0003] However, in the current fracturing process, a drilling rig is needed to deliver a single fracturing string into the hole. During the operation, on-site workers need to lift each string onto the drilling rig one by one and install it to the tail of the previous string through threaded connections. The fracturing strings are then delivered into the hole one by one. One operation may require repeated lifting and installation dozens or even hundreds of times, which is a huge workload. In addition, a 3-meter-long, 89-mm-diameter string weighs about 50 kg, which places high physical demands on workers and also poses certain safety hazards. Utility Model Content

[0004] The purpose of the embodiments of the present application is to provide a complete set of fracturing equipment equipped with continuous tubing to solve the problem that currently a manual assisted drilling rig is required to press multiple independent fracturing strings into the hole one by one, and the operation method has relatively large workload and safety hazards.

[0005] An embodiment of the present application discloses a complete fracturing equipment set equipped with coiled tubing, comprising a pumping mechanism, a coiled tubing storage and conveying mechanism, a control mechanism, and an energy supply mechanism. The pumping mechanism and the coiled tubing storage and conveying mechanism are both communicatively connected to the control mechanism, and the pumping mechanism is configured to communicate with a liquid supply mechanism. The coiled tubing storage and conveying mechanism comprises a winding rack and a drive assembly, both of which are connected to the energy supply mechanism. The winding rack is used to wind and retract the coiled tubing, and the drive assembly is used to drive the coiled tubing forward and / or backward.

[0006] The embodiment of the present application discloses a complete set of fracturing equipment equipped with a continuous tubing, which includes a pumping mechanism, a continuous tubing storage and conveying mechanism, and a control mechanism and an energy supply mechanism connected to both. The energy supply mechanism can provide energy to the pumping mechanism and the continuous tubing storage mechanism to enable the pumping mechanism and the continuous tubing storage and conveying mechanism to operate normally. At the same time, the pumping mechanism can be connected to the liquid supply mechanism so that the pumping mechanism can convey the corresponding liquid to the corresponding position in the hole through the continuous tubing. The continuous tubing storage and conveying mechanism includes a winding rack and a drive assembly. The winding rack can wind and retract the continuous tubing, and the drive assembly is connected to the energy supply mechanism so that the drive assembly can drive the continuous tubing to advance in the hole, so that the continuous tubing can be conveyed to a position at a preset depth in the hole. Correspondingly, the drive assembly can also drive the continuous tubing backward.

[0007] Obviously, since the fracturing equipment disclosed in the embodiment of the present application uses coiled tubing, and the coiled tubing can be pre-placed on a winding rack, there is no need for manual replacement and transportation of the coiled tubing during the fracturing process; and in the embodiment of the present application, the pumping mechanism and the coiled tubing storage and conveying mechanism are both communicatively connected to the control mechanism, so that the control mechanism can be used to control the operating status and operating parameters of the pumping mechanism and the coiled tubing storage and conveying mechanism, so that the staff does not need to perform corresponding control work on site, thereby significantly reducing the workload of workers and reducing the safety hazards in the fracturing process.

DETAILED DESCRIPTION

[0014] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0015] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0016] The embodiment of the present application discloses a complete set of fracturing equipment equipped with a continuous tubing, which can be used to transport the continuous tubing 7 into the hole and transport liquid into the hole through the continuous tubing 7. Figure 1 and Figure 3 As shown, the complete fracturing equipment equipped with coiled tubing disclosed in the embodiment of the present application includes a pumping mechanism 2 , a coiled tubing storage and transportation mechanism 6 , a control mechanism 4 and an energy supply mechanism 3 .

[0017] Among them, the pumping mechanism 2 can transport the corresponding liquid into the hole through the continuous pipe 7. To this end, the pumping mechanism 2 can be configured to be connected to the liquid supply mechanism 1. Optionally, the liquid supply mechanism 1 is set independently, or the liquid supply mechanism 1 can be a collection of storage or transportation mechanisms for different types of liquids. Of course, in other embodiments of the present application, the liquid supply mechanism 1 can be included in the fracturing equipment equipped with a continuous pipe disclosed in the embodiment of the present application. The liquid supply mechanism 1 can specifically be used to supply water, as well as other fluid media such as sand mixing liquid, filling slurry, pre-fluid and temporary plugging agent. At the same time, the pumping mechanism 2 is also connected to the energy supply mechanism 3 to use the energy supply mechanism 3 to provide driving energy for the pumping mechanism 2, so that the pumping mechanism 2 can pump liquid normally through the continuous pipe 7.

[0018] Specifically, the energy supply mechanism 3 is an electric power transmission mechanism. More specifically, the energy supply mechanism 3 is connected to an external power supply, and the pumping mechanism 2 and other mechanisms or devices that need to be powered can be connected to the energy supply mechanism 3. In a specific embodiment of the present application, the energy supply mechanism 3 includes a frequency converter, and the power supply is connected to the frequency converter to utilize the frequency converter to provide frequency modulation and other functions. In this case, the pumping mechanism 2 and other mechanisms or devices that need to be powered can be connected to the frequency converter. In addition, the frequency converter can also provide other functions such as variable frequency starting, speed regulation, and pumping pressure loss protection during operation for electrical devices such as the pumping mechanism 2 to ensure the smooth operation of each electrical device.

[0019] The coiled tubing storage and conveying mechanism 6 is used to store and convey the coiled tubing 7. Furthermore, in the coiled tubing-equipped fracturing equipment disclosed in the embodiments of the present application, the coiled tubing storage and conveying mechanism 6 is capable of storing the coiled tubing 7, or coiled oil tubing. The coiled tubing storage and conveying mechanism 6 includes a reel 64 and a drive assembly 65. The reel 64 is used to retract the coiled tubing 7. Specifically, the reel 64 can be a generally circular structure that allows it to reel in and retract the coiled tubing 7. In other words, the coiled tubing 7 can be stored on the reel 64 by being reeled in. The drive assembly 65 is connected to the energy supply mechanism 3, enabling the drive assembly 65 to propel the coiled tubing 7 within the wellbore, thereby continuously delivering it deeper into the hole.

[0020] Furthermore, a high-pressure rotary joint is mounted on the mandrel of the winding frame 64. One end of the rotary joint is internally connected to the coiled tubing 7, while the other end is externally connected to the discharge pipe of the pumping mechanism. This rotary joint eliminates the need to remove the discharge pipe of the pumping mechanism when advancing or rewinding the coiled tubing 7. Furthermore, the tubing can be advanced or retracted while water is being injected, preventing the in-hole tool string from becoming stuck.

[0021] Specifically, the drive assembly 65 can clamp the coiled tubing 7 by squeezing it. In this case, the friction between the clamping device and the coiled tubing 7 forces the tubing into the hole. The component squeezing the coiled tubing 7 generates a continuous rotational motion, thereby driving the coiled tubing 7 to advance and / or retract. Similarly, the drive assembly 65 can be connected to a power supply or inverter in the energy supply mechanism 3.

[0022] In a specific embodiment of the present application, the driving assembly 65 may include multiple pairs of clamping mechanisms, which may be clamping cylinders. Multiple groups of clamping cylinders are used to clamp and drive the coiled tubing 7 to advance in the hole.

[0023] In some other embodiments, the drive assembly may include a pair of clamping wheels and a drive device, such as a rotary motor, respectively connected to the two clamping wheels, specifically a first drive unit and a second drive unit, wherein the first drive unit is connected to the first clamping wheel, and the second drive unit is connected to the second clamping wheel. Based on this, under the combined action of the first drive unit and the second drive unit, both the first clamping wheel and the second clamping wheel can provide a driving function, thereby enabling the coiled tubing 7 to be clamped between the first and second clamping wheels. Under the action of the first and second drive units, the first and second clamping wheels can clamp and drive the coiled tubing 7 to advance within the hole.

[0024] With the above-described technical solution, since the clamping wheels on opposite sides of the coiled tubing 7 both have an active driving function, slippage of the coiled tubing 7 is virtually eliminated. Furthermore, with both the first and second clamping wheels providing driving functions, the driven efficiency and effectiveness of the coiled tubing 7 can be improved. Of course, to further enhance the driven efficiency of the coiled tubing 7, the drive assembly 65 can also include a driven clamping wheel assembly, specifically, a pair of clamping wheels disposed on either side of the first and second clamping wheels. Of course, the driven clamping wheel assembly need not be equipped with a driving device. The driven clamping wheel assembly can further enhance the clamping efficiency of the coiled tubing 7, thereby improving its driven efficiency. Furthermore, guide structures can be disposed on either side of the first and second clamping wheels to guide the portion of the coiled tubing 7 that will be clamped between the first and second clamping wheels, further enhancing the driven efficiency of the coiled tubing 7.

[0025] Furthermore, because the directions and elevations of the holes drilled in the coal mine are different, the driving assembly 65 can use tracks to adjust the direction and use a cylinder to adjust the elevation to achieve alignment of the continuous pipe entry direction with the hole.

[0026] At the same time, in the embodiment of the present application, as described above, the fracturing equipment equipped with coiled tubing includes a control mechanism 4, which can also be connected to the energy supply mechanism 3, so that the energy supply mechanism 3 supplies energy to the control mechanism 4. Of course, the control mechanism 4 can also be equipped with a separate power supply, etc., which is not limited in this article. When the fracturing equipment equipped with coiled tubing includes the control mechanism 4, the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 can both be communicatively connected to the control mechanism 4, so that the control mechanism 4 can control the operating status and operating parameters of the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 by sending control signals. Accordingly, the operating status and parameters of the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 can also be transmitted to the control mechanism 4 via communication, so that the control mechanism 4 can issue corresponding control commands based on the specific operating conditions of the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6. It should be noted that during the operation of the fracturing equipment equipped with coiled tubing disclosed in the embodiment of the present application, the control mechanism 4 can automatically control the operation of mechanisms such as the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 based on preset control logic and relevant operating condition information and other parameters. Alternatively, the operator can remotely control the operation of the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 through the control mechanism 4 based on relevant operating condition information and work experience.

[0027] The present application discloses a complete set of fracturing equipment equipped with a coiled tubing, which includes a pumping mechanism 2, a coiled tubing storage and conveying mechanism 6, and a control mechanism 4 and an energy supply mechanism 3 connected to both. The energy supply mechanism 3 can provide energy to the pumping mechanism 2 and the coiled tubing storage mechanism to enable the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 to operate normally. At the same time, the pumping mechanism 2 can be connected to the liquid supply mechanism 1 so that the pumping mechanism 2 can convey the corresponding liquid to the corresponding position in the hole through the coiled tubing. The coiled tubing storage and conveying mechanism 6 includes a winding rack 64 and a drive assembly 65. The winding rack 64 can wind and unwind the coiled tubing 7, and the drive assembly 65 is connected to the energy supply mechanism 3 so that the drive assembly 65 can drive the coiled tubing 7 forward in the hole, thereby allowing the coiled tubing 7 to be conveyed to a position at a preset depth in the hole. Correspondingly, the drive assembly 65 can also drive the coiled tubing 7 backward.

[0028] Obviously, since the fracturing equipment equipped with coiled tubing disclosed in the embodiment of the present application uses coiled tubing 7, and the coiled tubing 7 can be pre-placed on the winding rack 64, there is no need for manual replacement and transportation of the coiled tubing during the fracturing process. Moreover, in the embodiment of the present application, the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6 are both communicatively connected to the control mechanism 4, so that the control mechanism 4 can be used to control the operating status and operating parameters of the pumping mechanism 2 and the coiled tubing storage and conveying mechanism 6, so that workers do not need to perform corresponding control work on site, thereby significantly reducing the workload of workers and reducing safety hazards in the fracturing process.

[0029] Furthermore, the coiled tubing-equipped fracturing equipment disclosed in the embodiments of the present application may also include a data acquisition mechanism 5, which includes multiple sensors. One or more of the multiple sensors are mounted on the coiled tubing 7, so that as the coiled tubing 7 is advanced into the borehole, the sensors can also be advanced into corresponding positions within the borehole to collect borehole data during the operation. One or more of the multiple sensors may also be mounted on the pumping mechanism 2 to collect the pumping mechanism's operating conditions. Of course, corresponding sensors may also be mounted on other components of the fracturing equipment whose operating conditions need to be monitored. Simultaneously, by enabling each sensor to communicate with the control mechanism 4, the control mechanism 4 can also obtain corresponding data within the borehole, as well as data from the pumping mechanism 2, through the sensors. Specifically, the number of sensors may be multiple, and the multiple sensors may include pressure sensors, temperature sensors, vibration detection sensors, and the like. Of course, the sensors may also be devices for detecting other types of data, but for the sake of brevity, they are not listed here.

[0030] Among them, each sensor and the control mechanism 4 can be connected to each other by wireless communication. Considering that the communication conditions in the hole are usually relatively general, in order to ensure relatively high reliability of information transmission, in a specific embodiment of the present application, the data acquisition mechanism 5 also includes a data transmission line such as an optical fiber, and by arranging the optical fiber in the coiled tubing 7, the optical fiber and other data transmission lines will not be damaged during the advancement of the coiled tubing 7 in the well. Of course, in this embodiment, each sensor is communicatively connected to the control mechanism 4 via a data transmission line such as an optical fiber.

[0031] Furthermore, during the operation of the coiled tubing fracturing equipment disclosed in the embodiment of the present application, a tool string 8 is typically provided at the end of the coiled tubing 7 of the coiled tubing fracturing equipment, i.e., the end located at the deepest part of the hole. Furthermore, when the coiled tubing fracturing equipment utilizes the tool string 8 to perform isolation and pressurization operations, the data acquisition mechanism 5 can also be used to feed back corresponding detection data to the control mechanism 4 in real time, so that the control mechanism 4 can accurately evaluate the pressure effect.

[0032] As described above, the fracturing equipment equipped with coiled tubing disclosed in the embodiment of the present application includes a pumping mechanism 2. Optionally, there is only one pumping mechanism 2. In this case, the pumping mechanism 2 can be used to pump the liquid in the liquid supply mechanism 1. In order to improve parameters such as pumping efficiency and pumping power, in another embodiment of the present application, Figure 1 and Figure 3 As shown, there can be multiple pumping mechanisms 2, which are arranged in parallel and connected to the liquid supply mechanism 1, so that the liquid in the liquid supply mechanism 1 can be transported to corresponding positions in the well through the same continuous pipe 7 by the multiple pumping mechanisms 2. The multiple pumping mechanisms 2 can be connected to the liquid supply mechanism 1 through corresponding pipes, so that the liquid in the liquid supply mechanism 1 can be pumped by the pumping mechanisms 2. At the same time, the liquid supply ends of the multiple pumping mechanisms 2 can be connected to one end of the continuous pipe 7 located above the well through corresponding pipes, so that the multiple pumping mechanisms 2 can be arranged in parallel.

[0033] To facilitate the operation of the coiled tubing-equipped fracturing equipment disclosed in the embodiments of this application, the coiled tubing-equipped fracturing equipment disclosed in the embodiments of this application optionally includes a liquid supply mechanism 1, thereby enabling the coiled tubing-equipped fracturing equipment to store a certain amount of water or other fracturing fluids. More specifically, the liquid supply mechanism 1 includes a liquid supply tank having a certain liquid storage capacity. Thus, during the operation of the coiled tubing-equipped fracturing equipment, even if external liquid supply lines and other mechanisms are unable to continuously supply liquid, the liquid supply tank can be used to pre-store a certain amount of liquid to ensure that the pumping mechanism 2 can continue to operate. This can enhance the emergency operation capabilities of the coiled tubing-equipped fracturing equipment. Of course, parameters such as the shape and size of the liquid supply tank can be flexibly selected according to actual needs. In addition, it should be noted that during the transfer of the fracturing equipment equipped with a continuous tubing disclosed in the embodiment of the present application, it does not mean that the liquid supply mechanism 1 (including the liquid supply tank) must be carried along for the transfer. Instead, another liquid supply mechanism 1 can be re-provisioned at the next work site, thereby utilizing the liquid supply mechanism 1 at that site to provide the pumping mechanism 2 with the function of storing liquid again. This does not conflict with the fact that the fracturing equipment equipped with a continuous tubing disclosed in the embodiment of the present application includes the liquid supply mechanism 1.

[0034] In order to further extend the service life of the pumping mechanism 2 and improve the fracturing effect, in a specific embodiment of the present application, the fracturing equipment equipped with a continuous tubing also includes a filtering mechanism. The filtering mechanism is arranged at the liquid inlet end of the pumping mechanism 2, so that the filtering mechanism can filter the water or other liquids that are generally free of particulate matter and impurities transported by the pumping mechanism 2, thereby ensuring that the reliability of the pumping mechanism 2 is relatively high. More specifically, when the fracturing equipment equipped with a continuous tubing disclosed in the embodiment of the present application includes a liquid supply mechanism 1, the liquid supply tank of the liquid supply mechanism 1 can be connected to an external drain pipe, and the drain pipe can be used as a water source, as the source of the liquid required by the pumping mechanism 2. In this case, the filtering mechanism can be arranged at the discharge end of the liquid supply tank to filter the liquid output by the drain pipe, thereby ensuring that large particles of impurities do not enter the pumping mechanism 2, thereby extending the service life of the pumping mechanism 2. Of course, when it is necessary to pump other fluids such as sand mixing liquid, the water output from the drainage pipe can also be used to mix with other materials such as sand to form the required sand mixing liquid. This can also make the cleanliness of the formed sand mixing liquid relatively high, and make its particle size more uniform, ensuring smoother operation.

[0035] As described above, in the fracturing equipment equipped with coiled tubing disclosed in an embodiment of the present application, the coiled tubing storage and conveying mechanism 6 includes a drive assembly 65. The drive assembly 65 is capable of driving the coiled tubing 7 to advance within the well, that is, the drive assembly 65 is capable of actively extending the coiled tubing 7. Based on this, in a specific embodiment of the present application, the drive assembly 65 can also be enabled to have the ability to rotate in the opposite direction, so that the drive assembly 65 can also have the ability to recover the coiled tubing 7.

[0036] In another embodiment of the present application, Figure 2 As shown, the coiled tubing storage and conveying mechanism 6 further includes a winding rack power mechanism 62, which is connected to a winding rack 64 and can be used to drive the winding rack 64 to reel in the coiled tubing 7. Specifically, the winding rack power mechanism 62 provides power for the rotation of the winding rack 64 and can be a chain, belt, gear, or hydraulic structure.

[0037] That is, in the embodiment of the present application, a separate winding rack power mechanism 62 for recovering the coiled tubing 7 can be provided. The winding rack power mechanism 62 can drive the winding rack 64 to rotate, so that the coiled tubing 7 in the well can be continuously recovered and rewound onto the winding rack 64.

[0038] Furthermore, in the embodiment of the present application, the winding frame 64 and the winding frame power mechanism 62 can be mounted together on a device or structure that can serve as a mounting base, such as a frame, to ensure that the winding frame power mechanism 62 can properly drive the winding frame 64 to rotate relative to a reference object, such as the ground. Furthermore, the coiled tubing storage and conveying mechanism 6 can also be provided with a control box 63, with the drive assembly 65 and the winding frame power mechanism 62 both connected to the control box 63. The control box 63 can also be connected to the control mechanism 4, allowing the control mechanism 4 to directly control the operation of the drive assembly 65 and the winding frame power mechanism 62 via the control box 63.

[0039] Of course, while the drive assembly 65 is driving the coiled tubing 7 forward, the winding frame power mechanism 62 can be driven in reverse to cooperate with the drive assembly 65 in driving the coiled tubing 7 forward. Alternatively, while the drive assembly 65 is driving the coiled tubing 7 forward, the driving relationship between the winding frame power mechanism 62 and the winding frame 64 can be disconnected to prevent the winding frame power mechanism 62 from interfering with the normal operation of the drive assembly 65. Similarly, while the winding frame power mechanism 62 is rewinding the coiled tubing 7, the drive assembly 65 can be configured to operate in a similar manner to the winding frame power mechanism 62.

[0040] Based on the above embodiment, in a staged fracturing scenario, the reel-up mechanism 62 can be used to reel in the coiled tubing 7, thereby pulling a certain length of coiled tubing 7 out of the hole, thereby allowing the tool string 8 and other devices to be transferred to a new fracturing area. After the fracturing work in that area is completed, the reel-up mechanism 62 can be used to retract the coiled tubing 7 and drag the tool string 8 and other devices to another new fracturing area until the hydraulic fracturing work of the entire fracturing section is completed. During this process, there is no need for manual on-site replacement and removal of the coiled tubing, which can greatly improve operational efficiency and reduce worker workload and safety hazards.

[0041] As described above, the coiled tubing-carrying fracturing equipment disclosed in the embodiments of this application requires relocation. To this end, the pumping mechanism 2, coiled tubing storage and conveying mechanism 6, energy supply mechanism 3, and control mechanism 4 can all be mounted on a transportable device, such as a frame or skid, to facilitate the relocation of the coiled tubing-carrying fracturing equipment. Alternatively, the pumping mechanism 2, coiled tubing storage and conveying mechanism 6, energy supply mechanism 3, and control mechanism 4 can each be individually equipped with a transportable device, which can also ensure that the entire coiled tubing-carrying fracturing equipment has relocation capabilities.

[0042] Based on this, in a specific embodiment of the present application, Figure 2As shown, the coiled tubing storage and conveying mechanism 6 can include a traveling assembly 61. Specifically, the traveling assembly 61 can include a device with mobility, such as traveling wheels or traveling tracks. In addition, the winding rack 64 and the driving assembly 65 can be mounted on the same traveling assembly 61, thereby enabling the entire coiled tubing storage and conveying mechanism 6 to be capable of being transferred.

[0043] Of course, considering the growing demand for long-hole fracturing, a large-capacity winding rack 64 can be separately provided for the drive assembly 65. For example, a large-capacity winch can be used to provide the function of winding and releasing the coiled tubing 7, and the winch can be equipped with a high-power drive assembly to drive the coiled tubing 7. In this case, in another embodiment of the present application, Figure 3 As shown, the winding rack 64 and the driving assembly 65 can be separately provided, and the coiled tubing storage and conveying mechanism 6 can include a first traveling assembly and a second traveling assembly, wherein the winding rack 64 can be installed on the first traveling assembly, and the driving assembly 65 can be installed on the second traveling assembly. Thus, the entire coiled tubing storage and conveying mechanism 6 is structurally arranged in a separate state, but the driving assembly 65 and the winding rack 64 still cooperate with each other as a whole.

[0044] Based on the fracturing equipment equipped with continuous tubing disclosed in the above-mentioned embodiment of the present application, it can provide power for the drill bit of the drilling rig to carry out directional hole drilling. After the drilling is completed, the continuous tubing with the tool string can be carried to the fracturing section by the continuous tubing storage and transportation mechanism, and the pumping mechanism is used to perform clean water pressure pumping. During the process, with the help of the data acquisition mechanism and the control mechanism, long-distance real-time data monitoring can be carried out. Therefore, the fracturing equipment equipped with continuous tubing disclosed in the embodiment of the present application has the effect of one machine with multiple functions and a high degree of intelligence. It can greatly improve the efficiency of hydraulic fracturing, reduce the negative impact of rock burst, and improve the safety of mining operations.

[0045] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved.

In addition, the features described with reference to certain examples may be combined in other examples.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
