Description

Technical Field

[0001] This application belongs to the field of oil and gas extraction technology, specifically relating to a control device and extraction equipment. Background Technology

[0002] Manifolds are commonly used equipment in production and daily life. Taking the oil and gas extraction process as an example, manifolds are usually used to transport fluids such as fracturing fluid. Of course, in order to achieve the purpose of controlling the transport of fracturing fluid, valves are usually installed on the manifold. In order to achieve automatic opening and closing of valves, hydraulic valves are usually used to open and close the valves through hydraulic drive. Typically, fracturing equipment includes high and low pressure manifolds, diversion manifolds, and wellhead tree manifolds. The diversion manifolds and wellhead tree manifolds are installed near the wellhead and usually have multiple hydraulic valves. However, the hydraulic pumps that drive these valves are usually installed far from the wellhead. This means that the multiple hydraulic valves and pumps on the diversion manifolds and wellhead tree manifolds need to be connected one-to-one through multiple hydraulic lines. This results in multiple long hydraulic lines running between the wellhead and the area where the hydraulic pumps are located, making the hydraulic lines messy, difficult to assemble and manage, and difficult to troubleshoot in case of a malfunction, and posing a relatively high safety hazard. Utility Model Content

[0003] The purpose of this application is to provide a control device and mining equipment to solve the problem that in current mining equipment, the hydraulic valves usually installed on the diversion manifold and the wellhead tree manifold near the wellhead need to be connected to the hydraulic pump far away from the wellhead through multiple hydraulic lines. This results in multiple long hydraulic lines being laid between the wellhead and the area where the hydraulic pump is located, causing messy hydraulic line connections, relatively high assembly and management difficulty, difficulty in troubleshooting after a failure, and relatively high safety hazards.

[0004] In a first aspect, embodiments of this application disclose a control device applied to mining equipment. The mining equipment includes a drive mechanism and a delivery manifold. The delivery manifold is equipped with hydraulic valves. The control device includes an actuator and a controller. The actuator is equipped with an inlet and an outlet that are interconnected. The inlet is connected to the drive mechanism via an inlet pipeline. Each hydraulic valve on the delivery manifold is connected to a delivery pipeline, and each delivery pipeline is connected to the outlet. Each delivery pipeline is equipped with a control valve, and each control valve is connected to the controller. The controller is used to control the opening and closing state of each control valve to change the on / off state between the drive mechanism and the corresponding hydraulic valve.

[0005] Secondly, this application discloses a mining device, which includes a drive mechanism, a delivery manifold and the aforementioned control device. The drive mechanism is connected to the actuator, and the controller is used to control the opening and closing states of each of the control valves to change the on / off state between the drive mechanism and the corresponding hydraulic valve.

[0006] This application discloses a control device comprising an actuator and a controller. The actuator has an inlet and an outlet that are interconnected. The inlet can be connected to a drive mechanism via an inlet pipeline, and any hydraulic valve on the delivery manifold can be connected to a delivery pipeline in a corresponding manner. Each delivery pipeline is connected to an outlet. Simultaneously, each delivery pipeline is equipped with a control valve, allowing the on / off state of each delivery pipeline to be controlled by the corresponding control valve. In this case, by connecting each control valve to the controller, when it is necessary to open the corresponding hydraulic valve on the delivery manifold, only the controller needs to be used to open the corresponding control valve. This allows the drive fluid delivered by the drive mechanism to be delivered to the actuator via the inlet pipeline, and then flows from the corresponding delivery pipeline through the inlet and outlet to the corresponding hydraulic valve on the delivery manifold, completing the opening of the hydraulic valve.

[0007] As described above, the control device disclosed in this application can be applied to mining equipment. In this case, when assembling the mining equipment, the actuator of the control device can be installed only near the wellhead. In this case, the hydraulic valves usually installed on the diversion manifold and the wellhead tree manifold near the wellhead can be connected to the fluid delivery pipeline one by one, ensuring that the fluid delivery pipeline between each hydraulic valve and the drive mechanism can be individually controlled by the corresponding control valve. As for the fluid inlet of the actuator, it can be connected to the drive mechanism located far from the wellhead through only one fluid inlet pipeline. This can reduce the number of fluid inlet pipelines set between the actuator located at the wellhead and the drive mechanism located far from the wellhead, thereby preventing the pipelines around the wellhead from being messy, reducing the difficulty of assembly and management, and reducing safety hazards.

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0020] like Figures 1-3 As shown in the illustration, this application discloses a control device that can be applied to mining equipment, specifically fracturing equipment and cementing equipment, etc. For the sake of brevity, they will not be listed here. The mining equipment includes a drive mechanism and a delivery manifold, and the delivery manifold is equipped with a hydraulic valve 910. When the control device disclosed in this application is applied to mining equipment, the control device is used to control the on / off state of the control valve 350 on the fluid delivery line 320 connected to the corresponding hydraulic valve 910, thereby controlling the on / off state between the drive mechanism and the corresponding hydraulic valve 910 on the delivery manifold.

[0021] More specifically, the drive mechanism can be a hydraulically driven pump, and a valve is provided on the delivery manifold. This valve is a hydraulically actuated valve 910, meaning that the valve can be driven by hydraulic force to open and close. Of course, the specific form of the hydraulically actuated valve 910 can be flexibly selected according to the actual situation. For example, the hydraulically actuated valve 910 can be a hydraulically actuated plug valve or a hydraulically actuated gate valve, etc., which is not limited here.

[0022] Among them, such as Figure 1 As shown, the control device includes an actuator 100 and a controller. The controller controls the operating state of the control valve 350 to achieve the purpose of controlling the corresponding hydraulic valve 910 in the delivery manifold. The actuator 100 has an inlet and an outlet that are interconnected. It should be noted that the number of inlets is less than or equal to the number of outlets. Typically, there may be only one inlet, and there may be one or more outlets. Each outlet can be connected to the inlet through a cavity or other structure of the actuator 100. Of course, in other embodiments of this application, the actuator 100 may also be a structure similar to a tee or multi-way valve, with one opening as an inlet and the remaining one or more openings as outlets. This is not limited herein.

[0023] During the installation of the control device, the inlet can be connected to the drive mechanism through the inlet line 310. Specifically, the hydraulic line can be used to connect the actuator 100 to the hydraulic pump that serves as the drive mechanism, so that when the hydraulic pump is working, hydraulic oil can be delivered to the inlet of the actuator 100 through the hydraulic line.

[0024] Meanwhile, the drain port is also connected to the hydraulic valve 910 through a corresponding pipeline, specifically the infusion pipeline 320. Each hydraulic valve 910 on the infusion manifold is connected to the infusion pipeline in a corresponding manner. That is, when there are multiple hydraulic valves on the infusion manifold, there are also multiple infusion pipelines 320 to ensure that each hydraulic valve can correspond to one infusion pipeline 320. Furthermore, each infusion pipeline 320 is connected to the drain port, so that the hydraulic oil delivered by the drive mechanism to the actuator 100 through the infusion port can be delivered to multiple infusion pipelines 320 through the drain port to achieve the purpose of driving the corresponding hydraulic valve 910 to open and close.

[0025] Of course, to ensure that the opening and closing of each hydraulic valve 910 is controllable, in the control device disclosed in this application embodiment, each fluid delivery line 320 is equipped with a control valve 350. This allows the on / off state of each fluid delivery line 320 to be controlled by the corresponding control valve 350. That is, when the corresponding control valve 350 is open, the hydraulic oil delivered to the actuator 100 through the inlet can flow through the corresponding fluid delivery line 320 and the aforementioned control valve 350 to the corresponding hydraulic valve 910, thereby achieving the purpose of driving the hydraulic valve 910 to open and close.

[0026] In layman's terms, in the control device disclosed in this application embodiment, the actuator 100 and the infusion pipeline 320 are used to provide a "one-to-many" function. The path where the inlet is located is the main path, and the path where each infusion pipeline 320 is located is a branch path, and each branch path can be controlled by a corresponding control valve 350. Of course, the number of infusion pipelines 320 can be equal to the number of hydraulic valves 910 on the delivery manifold. In another embodiment of this application, the number of infusion pipelines 320 can also be greater than the total number of hydraulic valves 910 on the delivery manifold. After each hydraulic valve 910 on the delivery manifold is connected to a corresponding infusion pipeline 320, some infusion pipelines 320 can still be left unused. This gives the actuator 100 the ability to be modularly expanded to correspond and cooperate with hydraulic valves 910 further added in the mining equipment.

[0027] As described above, each infusion line 320 can be controlled by a corresponding control valve 350. Therefore, in the control device disclosed in this application embodiment, each control valve 350 is connected to a controller, so that the controller can control one or more corresponding control valves 350 to open or close as needed. That is, in this application embodiment, the controller is used to control the opening and closing state of each control valve 350 to change the on / off state between the drive mechanism and the corresponding hydraulic valve 910.

[0028] In one specific embodiment of this application, the control valve 350 is an electrically controlled valve to reduce the difficulty of controlling the control valve 350. More specifically, the control valve 350 can be a solenoid valve to improve the control accuracy of the control valve 350. Furthermore, each control valve 350 can be directly connected to the controller individually via a cable. In another embodiment of this application, the control device can also include a sub-control box, which can be set up near the wellhead along with the actuator. In this case, multiple control valves 350 are first connected to the sub-control box via a second cable 340, and the sub-control box is connected to the controller located away from the wellhead via a first cable 330, thereby reducing the number of power cables (i.e., the first cable 330 used for power supply and transmission of control commands) between the actuator 100 located near the wellhead and the controller located away from the wellhead.

[0029] This application discloses a control device, which includes an actuator 100 and a controller. The actuator 100 has an inlet and an outlet that are interconnected. The inlet can be connected to a drive mechanism through an inlet pipeline 310, and any hydraulic valve 910 on the delivery manifold can be connected to a delivery pipeline 320 in a corresponding manner. Each delivery pipeline is connected to an outlet. At the same time, each delivery pipeline 320 is equipped with a control valve 350, so that the on / off state of each delivery pipeline can be controlled by a corresponding valve. Controlled by valve 350, in this case, by connecting each control valve 350 to the controller, when it is necessary to open the corresponding hydraulic valve 910 on the delivery manifold, it is only necessary to use the controller to open the corresponding control valve 350, so that the driving fluid delivered by the drive mechanism can be delivered to the actuator 100 through the inlet line 310, and flow from the corresponding delivery line 320 through the inlet and outlet to the corresponding hydraulic valve 910 on the delivery manifold, thus completing the opening of the hydraulic valve 910.

[0030] As described above, the control device disclosed in this application embodiment can be applied to mining equipment. In this case, when assembling the mining equipment, the actuator 100 of the control device can be installed only at a location near the wellhead. In this case, the hydraulic valves 910 usually installed on the diversion manifold 810 and the wellhead tree manifold 820 near the wellhead can be connected to the fluid delivery line 320 one by one, ensuring that the fluid delivery line 320 between each hydraulic valve 910 and the drive mechanism can be individually controlled by the corresponding control valve 350. As for the fluid inlet of the actuator 100, it can be connected to the drive mechanism located far from the wellhead area through only one fluid inlet line 310. This can reduce the number of fluid inlet lines 310 set between the actuator 100 located at the wellhead and the drive mechanism located far from the wellhead, thereby preventing the existence of messy pipelines around the wellhead, reducing the difficulty of assembly and management, and reducing safety hazards.

[0031] As described above, when the corresponding control valve 350 is open, the drive mechanism can deliver hydraulic oil to the corresponding hydraulic valve 910 in the delivery manifold to drive the hydraulic valve 910 to open and close. Based on this, to determine whether the hydraulic valve 910 is in the correct position, in one specific embodiment of this application, the control device may further include a valve position detection sensor 360, and at least one hydraulic valve 910 in the delivery manifold may be equipped with a valve position detection sensor 360 to detect the position of the corresponding hydraulic valve 910. Of course, the valve position detection sensor 360 may also be connected to a controller via a cable, etc., to transmit the detected parameter information to the controller, allowing the controller to determine whether the corresponding hydraulic valve 910 is in the correct position based on the received valve position detection signal, and to control the drive mechanism to stop delivering hydraulic oil after the hydraulic valve 910 is in the correct position.

[0032] Specifically, the valve position detection sensor 360 may include one of the following sensors: proximity switch, electromagnetic sensor, micro switch, limit switch, and ultrasonic sensor, to detect the position of the hydraulic valve 910.

[0033] As described above, the delivery manifold is equipped with multiple hydraulic valves 910. Therefore, in one specific embodiment of this application, each hydraulic valve 910 on the delivery manifold can be equipped with a valve position detection sensor 360 to ensure that the opening degree of each hydraulic valve 910 can be detected by the corresponding valve position detection sensor 360. Of course, similar to the control valve 350, the multiple valve position detection sensors 360 can be independently connected to the controller directly via cables. In another embodiment of this application, the control device may further include a sub-control box, and each valve position detection sensor 360 is connected to a second cable 340 in a one-to-one correspondence. The other end of each second cable 340 can be connected to the sub-control box set in the actuator 100. The sub-control box can be connected to the controller via a first cable 330, thereby further reducing the number of control cables laid in the area between the actuator 100 located near the wellhead and the controller located far from the wellhead, further reducing the difficulty of assembly and maintenance, and reducing safety hazards.

[0034] As described above, the conveying manifold in the mining equipment is equipped with a hydraulic valve 910. Typically, the mining equipment also includes valves for providing other functions. The aforementioned valves can be collectively referred to as functional valves 920, and functional valves 920 can include at least one of a blowout preventer, a ball valve, and a pumping valve. When the control mechanism disclosed in the embodiments of this application is applied to the mining equipment, functional valves 920 can also be modified into hydraulic valves 910. That is, functional valves 920 include at least one of a hydraulic blowout preventer, a hydraulic ball valve, and a hydraulic pumping valve.

[0035] Based on this, in this embodiment of the application, each functional valve 920 in the mining equipment can be connected to a corresponding fluid delivery line 320, and the other end of each fluid delivery line 320 can be connected to a drain port. Of course, any fluid delivery line 320 can be connected to either a hydraulic valve 910 or a functional valve 920. Furthermore, it should be noted that the number of actuators 100 can be one or more. For example, one actuator 100 can simultaneously drive some of the hydraulic valves 910, while other hydraulic valves 910 and functional valves 920 can be driven by another actuator 100. Alternatively, there can be only one actuator 100, which drives all the hydraulic valves 910 and functional valves 920.

[0036] In this embodiment, several of the multiple infusion lines 320 are connected one-to-one with the hydraulic valves 910 on the delivery manifold, while one or more others are connected one-to-one with the functional valves 920. This allows the corresponding control valves 350 to respectively open and close the hydraulic valves 910 and the functional valves 920. That is, in this embodiment, the controller is also used to change the on / off state between the drive mechanism and the corresponding functional valve 920 by controlling the opening and closing state of the corresponding control valves 350, thereby changing the opening and closing state of the corresponding functional valves 920.

[0037] Similarly, in order to determine the opening and closing state of the functional valve 920, a valve position detection sensor 360 can be installed on the functional valve 920 to detect parameters such as the position of the corresponding functional valve 920. At the same time, the valve position detection sensors 360 that cooperate with the functional valve 920 are also connected to the controller to transmit the detection information to the controller. After the functional valve 920 is opened or closed, the controller controls the corresponding control valve 350 to close, thereby stopping the drive mechanism from supplying hydraulic oil to the corresponding functional valve 920.

[0038] As described above, the control device includes a controller. Optionally, in one specific embodiment of this application, the controller includes a local control mechanism, which can be arranged adjacent to the drive mechanism. As mentioned above, the drive mechanism is typically installed in an area relatively far from the wellhead in the well site. That is, an area can be set up around the well site at a location relatively far from the wellhead, serving as the installation space for mechanisms such as the drive mechanism located far from the wellhead. In this case, the local control mechanism can also be installed in the aforementioned area. "Adjacent" means that the distance between the local control mechanism and the drive mechanism is relatively smaller compared to other devices in the control device, such as the actuator 100; correspondingly, the distance between the local control mechanism and the actuator 100 is relatively larger. Optionally, the actuator 100 and the local control mechanism can be combined and arranged together as a power control unit 210 (i.e., a local control box) at a location far from the wellhead.

[0039] Of course, in order to ensure that the local control mechanism has interactive capabilities, the local control mechanism can usually include a display screen, which can be a touch screen. Alternatively, the local control mechanism can also include input devices such as control buttons, so that users can achieve the purpose of controlling the execution entity through the local control mechanism.

[0040] To further enhance the ease of control of the control device disclosed in this application embodiment, the controller may further include a remote control mechanism 220, which is communicatively connected to the local control mechanism. In this case, the user can use the remote control mechanism 220 to remotely control the actuator 100, thereby further enhancing the intelligence of the control device. Specifically, the remote control mechanism 220 may be a laptop computer or a control center, and the remote control mechanism 220 and the local control mechanism may be connected via wired connections such as network cables or buses (Modbus, Profinet, etc.) or wireless connections such as wireless signals (5G, 6G, WIFI, LoRa, etc.).

[0041] Based on the control device disclosed in the embodiments of this application, this application also discloses a mining equipment, which includes a drive mechanism, a delivery manifold and any of the above-mentioned control devices. The drive mechanism is connected to the actuator 100 in the control device. Each hydraulic valve 910 on the delivery manifold is connected to a corresponding fluid delivery line 320. Each fluid delivery line 320 is provided with a control valve 350, and each fluid delivery line 320 is connected to the actuator 100. Therefore, the controller in the control device can change the on / off state between the drive mechanism and the corresponding hydraulic valve 910 on the delivery manifold by controlling the opening and closing state of each control valve 350.

[0042] In detail, the delivery manifold may include a diversion manifold 810 and a wellhead tree manifold 820, both of which are typically located near the wellhead in the well site. In this case, by positioning the actuator 100 near the diversion manifold 810 and the wellhead tree manifold 820, any hydraulic valve 910 on the diversion manifold 810 and the wellhead tree manifold 820 can be connected to a delivery line 320 in a one-to-one correspondence. This allows the controller to change the on / off state between the corresponding hydraulic valve 910 on the diversion manifold 810 and the wellhead tree manifold 820 and the drive mechanism by controlling the control valve 350 on the corresponding delivery line 320.

[0043] In mining equipment, a high-low pressure manifold 830 is typically also included. Currently, the high-low pressure manifold 830 and any fracturing pump are interconnected using manual valves. To improve the level of automation control between the high-low pressure manifold 830 and the fracturing pump, the delivery manifold disclosed in this application also includes a high-low pressure manifold 830 in the mining equipment. That is, in this application embodiment, the high-low pressure manifold 830 is also equipped with hydraulic valves 910, and each hydraulic valve 910 is connected to a corresponding delivery pipeline 320. As mentioned above, in actual production, the number of actuators 100 can be one or more. Therefore, in this application embodiment, such as Figure 1 As shown, the hydraulic valves 910 of both the diversion manifold 810 and the wellhead tree manifold 820 can be connected to a certain actuator 100 via corresponding fluid delivery lines 320. The hydraulic valves 910 on the high-low pressure manifold 830 can be connected to another actuator 100. Of course, the hydraulic valves 910 on the diversion manifold 810, the wellhead tree manifold 820, and the high-low pressure manifold 830 can also be connected to the same actuator 100 via corresponding fluid delivery lines 320; this is not a limitation in this document.

[0044] Of course, in order to ensure that the degree of automation control of the hydraulic valves 910 on the diversion manifold 810, the wellhead tree manifold 820 and the high and low pressure manifold 830 is relatively high, in this embodiment of the application, each hydraulic valve 910 on the diversion manifold 810, the wellhead tree manifold 820 and the high and low pressure manifold 830 is connected to a fluid delivery line 320. Correspondingly, each fluid delivery line 320 is connected to the actuator 100, and each fluid delivery line 320 is equipped with a control valve 350, and each control valve 350 is connected to the controller.

[0045] In addition, when multiple high- and low-pressure manifolds 830 need to operate in series, the hydraulic valves 910 on each high- and low-pressure manifold 830 skid can be connected to the actuator 100 one-to-one via infusion lines 320. The control valves 350 on each infusion line 320 can be connected to the sub-control box in the actuator 100 via second cables 340, and the sub-control box can be connected to the controller via a first cable 330. Alternatively, wiring terminals can be provided on the control valves 350 of the infusion lines 320 of a high- and low-pressure manifold 830 skid adjacent to the actuator 100, and the control valves 350 of the infusion lines 320 of other high- and low-pressure manifolds 830 skids relatively far from the actuator 100 can be connected to the sub-control box via wiring terminals. Similarly, the wiring method between the valve position detection sensor 360 of the hydraulic valve 910 on each high- and low-pressure manifold 830 skid and the controller is similar to the wiring method between the control valve 350 and the controller. In general, different high and low pressure manifolds are connected in parallel on the 830 skid.

[0046] As described above, the mining equipment includes a high-low pressure manifold 830. To improve the control accuracy and closing reliability of the hydraulic valves 910 on the high-low pressure manifold 830, in one specific embodiment of this application, the hydraulic valves 910 on the high-low pressure manifold 830 can be hydraulic plug valves. However, the hydraulic valves 910 on the diversion manifold 810 and the wellhead tree manifold 820 can be gate valves; this is not a limitation herein.

[0047] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, it should be noted that the scope of the methods and apparatuses in the embodiments of this application is not limited to performing functions in the order shown or discussed, but may also include performing functions substantially simultaneously or in the reverse order, depending on the functions involved. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Additionally, features described with reference to certain examples may be combined in other examples.

[0048] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
