Description

Technical Field

[0001] This invention relates to the field of oil and gas extraction technology, specifically to intelligent extended modular units used in oil and gas extraction. Background Technology

[0002] Given the current booming development of "smart oil and gas fields" in China, the oil and gas industry is inevitably moving towards intelligentization. As a key component of oil and gas fields, modular control units serve as the command center for oil and gas field development and storage equipment at various stages, including exploration, drilling, repair, fracturing, oil (gas) production, gathering and transportation, and storage.

[0003] With continuous technological advancements and expanding operational scale, the demands on command and control systems for oil and gas field development and storage are becoming increasingly stringent. The command center must accommodate a large number of specialized equipment and technical personnel, ensuring efficient and stable operation in complex and ever-changing environments. The center houses instruments for controlling and manipulating the oil and gas field development and storage processes, as well as data servers, industrial control computers, network switches, and other equipment for data processing. It also includes conference tables, office chairs, and displays to provide central command for oil and gas field development and storage, and heating and ventilation equipment to provide a suitable working environment for the various instruments. Therefore, sufficient office space must be provided inside the command center.

[0004] Traditional fixed command modules only consider the spatial layout under operational conditions, and are assembled on-site from disassembled components. For oil and gas extraction command, it may be necessary to move according to changes in the extraction location, searching for suitable extraction points in different areas. To facilitate direct control of extraction equipment, the command center module also frequently moves. However, fixed command modules can only be disassembled and reassembled for use. This method not only increases the transportation, installation, and subsequent maintenance costs of fixed modules, but also makes it difficult to meet the needs of rapid deployment and flexible adjustment in remote oil and gas field areas with inconvenient transportation.

[0005] To overcome these challenges, modular cabins with unfolding and folding functions have emerged. These cabins fold compactly during transport, reducing space occupation; during operation, they unfold to provide a spacious and comfortable working space. For example, the pull-out, interconnected extendable cabin described in patent "CN2786025Y" consists of two extendable cabins on either side and a fixed-width fixed cabin. The extendable cabins are unfolded and folded via a telescopic mechanism at the bottom of the fixed cabin. Because the extendable cabins need to move relative to the fixed cabin, the air conditioning vents in typical modular cabins are located on the top of the fixed cabin. This means that when the cabin is folded, the top surface of the extendable cabin completely blocks the air vents, rendering the cabin's air conditioning system ineffective until the extendable cabins are fully extended.

[0006] If the oil and gas extraction operation environment is located in a high-altitude area, the temperature in the high-altitude area is around -30℃ all year round, which makes it impossible for electrical equipment that is not resistant to low temperatures to start. In addition, the accuracy of conventional position sensors used to provide feedback on the expansion distance of the extended cabin is reduced or no signal can be fed back due to the low temperature. Therefore, the traditional method of using position sensors to provide feedback on the expansion of the cabin cannot solve the problem of intelligent expansion of the cabin under low temperature conditions. Summary of the Invention

[0007] The present invention aims to provide an intelligent expandable container for oil and gas extraction, so as to enable the container to be intelligently expanded under low temperature conditions.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent extended container for oil and gas extraction, comprising a fixed container and two extended containers, the two extended containers being movably connected to both sides of the fixed container, the inner side of the extended containers communicating with the fixed container, a sealing wall extending circumferentially from the outer side of the extended containers, a sealing strip being provided on the inner side of the sealing wall, a fixed container floor being laid on the bottom surface of the fixed container, an extended container floor being fixedly connected to the inner side of the bottom surface of the extended containers, a folding floor being hinged between the extended container floor and the fixed container floor, low-temperature resistant electrical components being installed on the inner wall of the outer side of the extended containers and above the extended container floor, and electric heating plates covering the surfaces of the fixed container floor, the folding floor, and the extended container floor.

[0009] The working principle and advantages of this modular shelter are as follows: When smart oil and gas field operations are conducted in high-altitude, low-temperature regions, this extended shelter mounts electrical components that are not resistant to low temperatures on the inner wall of the outer exterior of the shelter. When not in use, the extended shelter is in a retracted state. When expansion is required, the electric heating plate circuit is first activated manually, heating the fixed floor, folding floor, and extended floor. The heated surfaces of the folding and extended floors face the electrical component installation locations. This preheats the electrical components until the ambient temperature of all components meets their operating temperature. Once all components are within their normal operating temperature range, the expansion system is activated to deploy the extended shelter.

[0010] Once fully deployed, this modular unit can connect to relevant equipment at each stage of the smart oil and gas field via the Internet of Things (IoT), enabling intelligent command, monitoring, safety protection, and inspection of the equipment. This intelligent expandable modular unit can be used in various stages, allowing it to be rotated across multiple operational phases and reducing hardware costs in all aspects of oil and gas extraction, storage, and transportation.

[0011] In addition, when the extended compartment is folded, a sealing wall extends circumferentially from the outer side of the extended compartment. A sealing strip is provided on the inner side of the sealing wall, and the extended compartment is completely sealed to the fixed compartment. This also prevents internal heat loss and preheating failure during the preheating process of electrical components that are not resistant to low temperatures.

[0012] Furthermore, the electric heating plate structure includes a floor frame, on which two layers of moisture-proof boards are laid, and graphene heating wires are laid between the two layers of moisture-proof boards. The upper moisture-proof board is covered with a surface plate for people to walk on.

[0013] Graphene heating wires heat up six times faster than traditional underfloor heating, reaching a comfortable temperature in a short time. Graphene heating wires can achieve uniform heating across the entire heating surface, avoiding the problem of uneven heating in traditional heating materials.

[0014] Furthermore, a heat-reflective layer is laid on the inner wall of the bottom of the extended cabin. This allows heat radiated onto the bottom surface of the extended cabin to be reflected and utilized when the cabin is folded up.

[0015] Furthermore, the bottom of the fixed cabin is provided with a cabin beam frame, and a folding space is left between the fixed cabin and the cabin beam frame. An extension mechanism is installed on the cabin beam frame to drive the expansion cabins on both sides to unfold and fold. The extension mechanism includes a stroke mechanism to drive the expansion cabins to move. The stroke mechanism includes a slide groove fixedly installed on the cabin beam frame, a power gear installed in the slide groove, and a rack fixed to the bottom of the expansion cabin, the rack meshing with the power gear.

[0016] This modular container uses a rack and pinion system with a drive gear to determine the travel distance. Since the tooth spacing of the rack is a fixed value, the amount of movement of the extended container can be obtained by judging the amount of gear rotation. This eliminates the need for sensors as position feedback components and accurately determines the extension travel distance of the extended container, reducing the use of sensing components and avoiding low-temperature failure.

[0017] Furthermore, the expansion mechanism also includes a transmission mechanism that provides power to the travel mechanism. The transmission mechanism includes a servo motor, a reducer, and a drive shaft. The output end of the servo motor is connected to the reducer and the drive shaft in sequence. The drive shaft is coaxially connected to the power gear. An absolute encoder is coaxially mounted on the servo motor. The absolute encoder is communicatively connected to a controller. The absolute encoder has at least three encoder disks, and the number of tracks on a single encoder disk is at least 2^24. The absolute encoder acquires the rotation amount of the servo motor. The controller calculates the movement amount of the expansion compartment based on the rotation amount of the servo motor and controls the rotation amount of the servo motor to determine the movement position of the expansion compartment.

[0018] This application uses a servo motor as the power source and is equipped with a high-precision absolute encoder. The absolute encoder converts the motor's rotation angle into an electrical signal, which is then fed back to the controller. The servo motor obtains precise position information from the encoder with an extremely small error range, and eliminates the need for temperature-sensitive sensors, thus avoiding sensor failure at low temperatures. Furthermore, the combination of multiple encoder disks and multiple tracks enables finer and more precise control of the floor movement.

[0019] Furthermore, a rectangular conference table is fixedly installed at the axis of symmetry of the fixed cabin floor. The conference table includes a fixed tabletop fixed at the axis of symmetry of the fixed cabin floor, and two movable tabletops are hinged to both sides of the fixed tabletop. A lifting rod is hinged to the bottom surface of the movable tabletops.

[0020] Using a folded conference table allows the extended cabin to have more space to fold inwards, bringing low-temperature-sensitive electrical components closer to the heating plate and reducing preheating time.

[0021] Furthermore, a photovoltaic panel is laid on the top of the fixed cabin, and a top heating plate with the same power supply circuit as the electric heating plate is provided below the photovoltaic panel. The photovoltaic panel is slightly tilted.

[0022] In low-temperature environments, the top of the shelter often accumulates ice or snow. Since the power supply circuit of the top heating plate and the electric heating plate is the same, the heat generated by the top heating plate melts the snow or ice on the photovoltaic panel before it can be used, allowing the photovoltaic panel to be used in low-temperature environments with sunlight.

[0023] Furthermore, a lifting mechanism is provided between the folding floor and the inner side of the extended cabin. The lifting mechanism includes a first lifting ridge fixed below the folding floor and a second lifting ridge fixed to the inner wall of the bottom of the extended cabin. The top of the first lifting ridge faces down and the top of the second lifting ridge faces up. When the extended cabin is fully extended, the two inclined surfaces of the first and second lifting ridges are in contact with each other.

[0024] After the extended cabin is fully deployed, the folding floor becomes flat and coplanar. To avoid dead spots at the folding point of the floor during the initial folding of the extended cabin, which would prevent the floor from folding properly, when folding is required, with the extended cabin fully deployed, the first and second lifting edges are in contact. As the extended cabin begins to fold, the lifting mechanism applies an upward thrust to one section of the folding floor, causing the folding point to bypass the dead spot and completing the normal folding of the floor.

[0025] Furthermore, the extended compartment floor is hinged to a C-shaped telescopic groove, and one end of the folding floor is slidably connected within the C-shaped telescopic groove. The C-shaped telescopic groove is reserved with a telescopic allowance for the movement of the folding floor.

[0026] By using the telescopic groove design, the expansion compartment is first moved by the telescopic allowance. This telescopic allowance ensures that the tilting mechanism can successfully make the folding point of the folding floor avoid the dead point, thus avoiding the problem of the folding floor failing to fold.

[0027] Furthermore, it also includes a centralized control system deployed inside the container. The centralized control system includes an industrial computer and a controller. The PLC controller communicates with the oil and gas field equipment and sensors through a serial port server for process control of the oil and gas field equipment and data acquisition of the oil and gas field. The industrial computer includes multiple industrial computers, which are connected to the PLC controller via a data switch. The industrial computer is also connected to a video display via a video processor.

[0028] In low-temperature environments, heating plates are used to preheat the industrial control computers and PLC controllers, ensuring the normal operation of the core electrical equipment of the control system within the shelter. A serial port server filters data transmissions between the external and internal networks, while a video monitor displays the currently viewed industrial control computer interface. The monitor can switch between any industrial control computer interface based on the signal channel, providing a comprehensive view of all aspects of the current operation.

[0029] The centralized control system controls the internal systems of the command cabin on one hand, and connects to peripheral equipment at various stages of the oil and gas field via signal lines on the other. This peripheral equipment includes exploration equipment, drilling equipment, maintenance equipment, fracturing equipment, oil and gas production equipment, gathering and transportation equipment, and storage and transportation equipment. Based on the operational location of the command cabin, the equipment requiring control at that location is selected and connected to the centralized control system. The centralized control system then calls the control software for the corresponding stage to control all peripheral equipment at that location. When the operational location changes, the same operating method is used to connect the corresponding equipment requiring centralized control at that location back to the centralized control system. In this way, a single command cabin can control all operational modes of the oil and gas field.

[0030] Furthermore, it also includes an intelligent power distribution system, which includes a three-phase power supply circuit and a single-phase power supply circuit. The three-phase power supply circuit includes three live wires for drawing three-phase power and a neutral wire connected to the neutral wire. The three live wires and the neutral wire form three independent power circuits. A first contactor for controlling the conduction of the three live wires is connected to the three live wires. The single-phase power supply circuit includes a single-phase live wire and a common neutral wire with the three-phase power supply circuit. The single-phase live wire branches into three parallel single-phase live wires. The three single-phase live wires are first connected to a second contactor and then to the incoming side of the three power circuits respectively. An uninterruptible power supply is connected in parallel to one of the three power circuits.

[0031] When using three-phase power, the three-phase power supply circuit is connected to the three-phase power supply. The normally open contact of the first contactor closes, and the three live wires of the three-phase power supply become the power circuits for the intelligent expansion container for oil and gas extraction. Any equipment within the intelligent expansion container can be connected to one of these power circuits. When using single-phase power, the single-phase power supply circuit is connected to the single-phase power supply. The single live wire in the single-phase power supply circuit is divided into three paths, and each path is connected to one of the three power circuits. When the second contactor closes, all three power circuits are energized simultaneously to power the equipment within the intelligent expansion container for oil and gas extraction. An uninterruptible power supply (UPS) is connected in parallel to one of the three power circuits. When either the three-phase or single-phase power supply circuit is providing power, it charges the UPS. Control signals from equipment inside the container and equipment outside the work area are connected to this power circuit.

[0032] The power circuits for the intelligent expansion modular shelter for oil and gas extraction include: power circuits for server racks, servers, transmission mechanisms, tilting mechanisms / lifting masts, lighting, unmanned aerial vehicle (UAV) systems, public display areas, conference multimedia systems, air conditioning, graphene heated floors, mains power outlets, UPS power outlets, communication systems, ventilation systems, and intelligent control systems. These circuits are connected to the appropriate power supply circuits as needed to power the equipment on those circuits.

[0033] Furthermore, it also includes an intelligent inspection system, which includes an unmanned aerial vehicle (UAV) airport located in a fixed cabin. The top of the fixed cabin has a bay that can accommodate multiple UAVs. The UAV airport is equipped with a lifting platform, through which UAVs are sent into the UAV airport. The lifting platform is equipped with a positioning pole and a wireless charger. The UAVs have a lightweight photovoltaic film on their surface, and they are equipped with multispectral cameras and LiDAR. The UAV software is equipped with the RANSAC-SLAM algorithm to generate centimeter-level accuracy maps. The multispectral camera, LiDAR, and centimeter-level accuracy maps together constitute the UAV's navigation environment for accurately planning the UAV's navigation path.

[0045] The following detailed description illustrates the specific implementation method:

[0046] The reference numerals in the accompanying drawings include: fixed cabin 1; extended cabin 2; sealing wall 21; sealing strip 22; fixed cabin floor 3; extended cabin floor 31; C-shaped telescopic groove 32; folding floor 4; first warping ridge 41; second warping ridge 42; rack 5; conference table 6; cabin beam frame 7; servo motor 71; absolute encoder 72; reducer 73; drive shaft 74; slide 75; electrical components not resistant to low temperatures 8; power gear 10; photovoltaic panel 11; functional cabin 12; warm air cabin 13; air outlet 14; unmanned airport 15; air conditioner outdoor unit 16; ladder 17.

[0047] Example 1

[0048] The basics are as follows: Figure 1 , Figure 2 , Figure 4 and Figure 10As shown, the intelligent expandable container for oil and gas extraction includes a fixed container 1 and two expandable containers 2. The two expandable containers 2 are movably connected to both sides of the fixed container 1. The inner side of the expandable containers 2 is connected to the fixed container 1. A sealing wall 21 extends circumferentially from the outer side of the expandable containers 2. A sealing strip 22 is provided on the inner side of the sealing wall 21. The bottom surface of the fixed container 1 is covered with a fixed container floor 3. The inner side of the bottom surface of the expandable containers 2 is fixedly connected to the expandable container floor 31. A folding floor 4 is hinged between the expandable container floor 31 and the fixed container floor 3.

[0049] Electrical components 8 that are not resistant to low temperatures are installed above the floor 31 of the expansion compartment and on the inner wall of the outer side of the expansion compartment. The upper surfaces of the fixed compartment floor 3, the folding floor 4, and the expansion compartment floor 31 are all covered with electric heating plates. The electric heating plate structure includes a floor frame, two layers of moisture-proof boards are laid on the floor frame, graphene heating wires are laid between the two layers of moisture-proof boards, and a surface plate for people to walk on is covered by the upper moisture-proof board.

[0050] Graphene heating wires heat up six times faster than traditional underfloor heating, reaching a comfortable temperature in a short time. The graphene heating wires also ensure uniform heating across the entire heating surface, avoiding the uneven heating problems of traditional heating materials. A heat-reflective layer is installed on the inner wall of the bottom of the extended chamber to prevent heat loss from the bottom.

[0051] In the power supply of the extended cabin, a separate power supply circuit is arranged for the electric heating plate. This power supply circuit is equipped with a manually operated mechanical switch. The operation position of the mechanical switch is outside the extended cabin, so that only the power supply circuit for the electric heating plate can be activated before other equipment is powered on.

[0052] When operating in high-altitude, low-temperature regions, this extended modular unit installs the low-temperature-resistant electrical components 8 on the inner wall of the outer side of the extended modular unit 2. When not in use, the extended modular unit 2 is in a retracted state. When expansion is required, the electric heating plate circuit is manually activated, heating the fixed floor 3, the folding floor 4, and the extended floor 31. The heating surfaces of the folding floor 4 and the extended floor 31 are directly opposite the installation locations of the low-temperature-resistant electrical components 8. This preheating ensures that all low-temperature-resistant electrical components 8 are within their normal operating temperature range. At this point, the expansion system is activated, causing the extended modular unit to unfold.

[0053] like Figure 1 and Figure 3 As shown, the inner edge of the extended cabin 2 is provided with an inner sealing wall, and a sealing strip 22 is provided on the inner sealing wall. When the extended cabin is fully extended, the sealing strip 22 on the inner sealing wall is tightly fitted with the fixed cabin 1 to prevent heat loss after the extended cabin 2 is fully extended.

[0054] Example 2

[0055] like Figure 1 , Figure 4 and Figure 9 As shown, the bottom of the fixed cabin 1 is provided with a cabin beam 7, and a folding space is left between the fixed cabin 1 and the cabin beam 7. An extension mechanism is installed on the cabin beam 7 to drive the expansion cabins on both sides to unfold and fold. The extension mechanism includes a stroke mechanism to drive the expansion cabins to move. The stroke mechanism includes a slide groove 75 fixedly installed on the cabin beam, a power gear 10 installed in the slide groove 75, and a rack 5 fixed to the bottom of the expansion cabin. The rack 5 meshes with the power gear 10.

[0056] The extension mechanism also includes a transmission mechanism that provides power to the travel mechanism. The transmission mechanism includes a servo motor 71, a reducer 73, and a drive shaft 74. The output end of the servo motor 71 is connected to the reducer 73 and the drive shaft 74 in sequence. The drive shaft 74 is coaxially connected to the power gear 10. An absolute encoder 72 is coaxially mounted on the servo motor 71. The absolute encoder 72 is communicatively connected to a controller. The absolute encoder 72 has at least three encoder disks, and the number of tracks on a single encoder disk is at least 2^24. The absolute encoder obtains the rotation amount of the servo motor 71. The controller calculates the movement amount of the extension compartment 2 based on the rotation amount of the servo motor 71 and controls the rotation amount of the servo motor to determine the movement position of the extension compartment 2.

[0057] It employs a servo motor as the power source and is equipped with a high-precision absolute encoder. The absolute encoder converts the motor's rotation angle into an electrical signal, which is then fed back to the controller. The servo motor utilizes the precise position information fed back by the encoder with an extremely small error range, eliminating the need for temperature-sensitive sensors and avoiding sensor failure in low-temperature conditions. Furthermore, the combination of multiple encoder disks and multiple tracks enables finer and more precise control of the floor movement. The servo motor is driven by a dedicated driver.

[0058] Because the high-altitude, low-temperature environment prevents the use of temperature-sensitive sensors, a servo motor with a stall stop function and self-protection is selected. In this embodiment, an NSD8381 / NSD8389 stepper motor can be used. This motor has a temperature range of -40℃ to +85℃ and its driver supports sensorless stall detection, effectively detecting motor stall conditions. If gears or racks jam during the extension compartment traction process, the servo motor itself detects the stall, stops traction, and issues an alarm.

[0059] This solution eliminates the traditional gearbox and directly connects the output shaft of the servo motor to the reducer. Sufficient traction force is required to achieve expansion. In this embodiment, the reducer selected is the NMRV130 worm gear reducer with a reduction ratio of 100:1.

[0060] Example 3

[0061] like Figure 1 and Figure 5 As shown, a lifting mechanism is provided between the folding floor 4 and the inner side of the extended compartment 2. The lifting mechanism includes a first lifting ridge 41 fixed below the folding floor and a second lifting ridge 42 fixed to the inner wall of the bottom of the extended compartment 2. The top of the first lifting ridge 41 faces down and the top of the second lifting ridge 42 faces up. When the extended compartment 2 is fully unfolded, the two inclined surfaces of the first lifting ridge 41 and the second lifting ridge 42 are in contact.

[0062] After the extended compartment 2 is fully extended, the folding floor 4 becomes flat and coplanar. To avoid a dead point at the folding point of the folding floor during the initial folding of the extended compartment 2, which would prevent the folding floor from folding properly, when folding is required, with the extended compartment fully extended, the two inclined surfaces of the first and second lifting edges 41 and 42 are in contact. When the extended compartment 2 begins to fold, the lifting mechanism applies an upward thrust to one of the folding floor sections, causing the folding point of the folding floor to bypass the dead point, thus completing the normal folding of the folding floor.

[0063] like Figure 6 and Figure 7 As shown, the extension compartment floor 31 is hinged to a C-shaped telescopic groove 32. One end of the folding floor 4 is slidably connected within the C-shaped telescopic groove 32, which provides a telescopic allowance for the movement of the folding floor 4. Through the design of the telescopic groove, the extension compartment 2 moves by the telescopic allowance first. This allowance ensures that the tilting mechanism can successfully guide the folding point of the folding floor away from the dead point, avoiding the problem of the folding floor failing to fold.

[0064] A rectangular conference table 6 is fixedly installed at the axis of symmetry of the fixed cabin floor 3. The conference table 6 includes a fixed tabletop fixed at the axis of symmetry of the fixed cabin floor 3, and two movable tabletops are hinged to each side of the fixed tabletop. A lifting rod is hinged to the bottom of the movable tabletop.

[0065] like Figure 8 As shown, the two ends of the fixed cabin 1 are independent functional cabins 12 and heating cabins 13. The functional cabin 12 is equipped with a lifting car. The top of the functional cabin 12 is provided with an opening to allow the lifting car to rise to the top of the functional cabin. The top of the lifting car is provided with a sealing plate to seal with the opening at the top of the functional cabin when the lifting car is stored in the functional cabin.

[0066] The functional compartment and the heated compartment are part of the fixed cabin. A lift car is installed in the functional compartment, which allows personnel inside the compartment to access the top surface of the functional compartment. When the lift car is not in use, it is used as a storage room. The top of the lift car is equipped with a sealing plate to prevent heat loss from the functional compartment.

[0067] like Figure 6 As shown, a photovoltaic panel is installed on the top of the fixed cabin. The photovoltaic panel is connected to the top of the fixed cabin through an automatic tracking system. The automatic tracking system includes a rotating shaft for controlling the adjustment angle of the photovoltaic panel, a photosensitive sensor for determining the position of the sun, and a gyroscope angle sensor for determining the adjustment direction of the rotating shaft.

[0068] The photovoltaic panels provide electricity for the extended cabin. When there is sufficient sunlight, the automatic tracking system adjusts the posture of the photovoltaic panels so that they are tilted and directly exposed to sunlight. During the power generation process, the solar heat and the waste heat generated by the photovoltaic panels can melt the snow or ice on the panels, allowing them to be used in low-temperature environments with sunlight.

[0069] like Figure 10 As shown, the heating chamber 13 is equipped with a ladder 17, which allows staff to access the top of the cabin for work.

[0070] An air conditioning unit is installed inside the warm air chamber 13, and an air outlet 14 extending to the functional chamber is installed on the top of the fixed chamber 1. After the expanded cabin is preheated and successfully expanded, the air conditioning unit 16 is turned on, and the warm air from the air conditioner is introduced into the entire expanded cabin and functional chamber through the air outlet to ensure that the temperature in the entire cabin is maintained in a comfortable environment.

[0071] Example 4

[0072] like Figure 8 As shown, a retractable drone airfield 15 is also provided on top of the fixed cabin, protected by a cover. Drones are normally placed inside the airfield 15. When drone operations are required, the cover on top of the airfield 15 is opened to release the drone. The airfield is equipped with a lifting platform, through which the drone is sent into the airfield. The lifting platform is equipped with a positioning rod and a wireless charger. The drone has a lightweight photovoltaic film on its surface, and is equipped with a multispectral camera and LiDAR. The drone software uses the RANSAC-SLAM algorithm to generate centimeter-level accuracy maps. The multispectral camera and LiDAR, together with the centimeter-level accuracy maps, constitute the drone's navigation environment for accurately planning its navigation path. The lightweight photovoltaic film extends the drone's flight time to 120 minutes.

[0073] Example 5:

[0074] like Figure 11As shown, the intelligent power distribution system of the intelligent expansion container for oil and gas extraction includes a three-phase power supply circuit and a single-phase power supply circuit. The three-phase power supply circuit includes three live wires L1 / L2 / L3 for three-phase power supply and a neutral wire N connected to the neutral line. The three live wires L1 / L2 / L3 and the neutral wire N form three independent power circuits. A first contactor KM1 for controlling the conduction of the three live wires is connected to the three live wires L1 / L2 / L3. The single-phase power supply circuit includes a single-phase live wire L and a common neutral wire N with the three-phase power supply circuit. The single-phase live wire branches into three parallel single-phase live wires L. The three single-phase live wires L are first connected to the second contactor KM2 and then connected to the incoming line side of the three power circuits respectively. An uninterruptible power supply (UPS) is connected in parallel to one of the three power circuits.

[0075] When using three-phase power, the three-phase power supply circuit is connected to the three-phase power supply. The normally open contact of the first contactor closes, and the three live wires of the three-phase power supply become the power circuits for the intelligent expansion container for oil and gas extraction. Any electrical equipment within the intelligent expansion container can be connected to one of these power circuits. When using single-phase power, the single-phase power supply circuit is connected to the single-phase power supply. The single live wire in the single-phase power supply circuit is divided into three paths, and each path is connected to one of the three power circuits. When the second contactor closes, all three power circuits are energized simultaneously to power the equipment within the intelligent expansion container for oil and gas extraction. An uninterruptible power supply (UPS) is connected in parallel to one of the three power circuits. When either the three-phase or single-phase power supply circuit is providing power, it charges the UPS. Control equipment within the intelligent expansion container used for data transmission and signal processing is connected to this power circuit.

[0076] The power circuits for the intelligent expansion modular shelter for oil and gas extraction include: power circuits for server racks, servers, transmission mechanisms, tilting mechanisms / lifting masts, lighting, unmanned aerial vehicle (UAV) systems, public display areas, conference multimedia systems, air conditioning, graphene heated floors, mains power outlets, UPS power outlets, communication systems, ventilation systems, and intelligent control systems. These circuits are connected to the appropriate power supply circuits as needed to power the equipment on those circuits.

[0077] The work site is also independently equipped with high-efficiency monocrystalline silicon photovoltaic modules, which are also connected to the intelligent power distribution system of the intelligent expansion container for oil and gas extraction, and photovoltaic power supply is given priority.

[0078] Example 6

[0079] The intelligent extended container for oil and gas extraction adopts a centralized control method. A centralized control system is deployed in the container, which includes industrial control computers and controllers. The PLC controller communicates with oil and gas field equipment and sensors through a serial port server for process control of oil and gas field equipment and data acquisition. There are multiple industrial control computers, which are sequentially connected to the serial port server and the switch. The switch then connects to the data server, which in turn connects to the video processor. The video processor is also connected to each monitor in the container.

[0080] In low-temperature environments, heating plates are used to preheat the industrial control computer and PLC controller, ensuring that the core electrical equipment of the control system in the shelter can operate normally. The video display uses a splicing screen to form a central large screen, which can be switched to any industrial control computer's working interface according to the signal channel, providing a comprehensive display of all aspects of the current operation.

[0081] The centralized control system controls the internal systems of the command cabin on one hand, and connects to peripheral equipment at various stages of the oil and gas field via signal lines on the other. This peripheral equipment includes exploration equipment, drilling equipment, maintenance equipment, fracturing equipment, oil and gas production equipment, gathering and transportation equipment, and storage and transportation equipment. Based on the operational location of the command cabin, the equipment requiring control at that location is selected and connected to the centralized control system. The centralized control system then calls the control software for the corresponding stage to control all peripheral equipment at that location. When the operational location changes, the same operating method is used to connect the corresponding equipment requiring centralized control at that location back to the centralized control system. In this way, a single command cabin can control all operational modes of the oil and gas field.
