Description

Technical Field

[0001] This invention relates to the field of drilling engineering technology and is a power supply device for oil drilling campsites. Background Technology

[0002] Oil drilling camps are essential living facilities for drilling team employees during field operations. They are equipped with a full range of facilities, including an operating room, washroom, canteen, and dormitory. They are assembled from iron camps and are equipped with electrical facilities such as television, lighting, heating, and air conditioning. They are fully equipped to meet the needs of eating, lodging, meetings, and entertainment.

[0003] A standard drilling apartment typically consists of more than ten iron-framed barracks, equipped with a full set of electric kitchen appliances and electrical facilities such as television, lighting, and communication, with a total power of 200-300KW. Its daily electricity consumption is about 3,000 kWh, which is an important component of drilling electricity costs.

[0004] Drilling site conditions are harsh, with cold winters and hot summers, requiring the continuous use of air conditioning and electric heating. A single drilling apartment consumes approximately 100,000 kilowatt-hours of electricity per month, or about 1,000,000 kilowatt-hours per year. If diesel generators were used for power supply, the cost of generating electricity could reach approximately 2 million yuan. Furthermore, because the power supply comes from the drilling rig's power grid, it fluctuates with the grid fluctuations caused by drilling operations, significantly reducing the lifespan of electrical equipment.

[0005] Therefore, there is an urgent need for a power supply device for oil drilling campsites to solve the aforementioned technical problems. Summary of the Invention

[0006] This invention provides a power supply device for oil drilling campsites, which overcomes the shortcomings of the prior art and can effectively solve the problems of high electricity costs and large impacts on the drilling power grid at drilling sites.

[0007] The technical solution of the present invention is achieved through the following measures: a power supply device for oil drilling campsites, comprising a main power supply system and a solar power generation system, wherein the main power supply system and the solar power generation system are electrically connected by an automatic switching switch; The main power supply system includes diesel generator sets; The solar power generation system includes solar panels, a solar inverter / controller unit, and batteries. The solar panels and batteries are electrically connected to the solar inverter / controller unit.

[0008] The following are further optimizations and / or improvements to the above-mentioned technical solution: The aforementioned main power supply system may also include gas generator sets and municipal power grids, with the gas generator sets, municipal power grids, and diesel generator sets serving as backups for each other.

[0009] It may also include an intelligent control system, which is electrically connected to the main power supply system and the solar power generation system, and is used to intelligently control the power supply to the oil drilling camp.

[0010] It may also include a barracks power control unit, which is installed in the control box of each barracks and is used to control the power consumption of that barracks individually.

[0011] The aforementioned solar inverter control unit can be equipped with a built-in MPPT controller, which can be used to quickly and accurately find the maximum power point of the photovoltaic cell using the maximum power point tracking algorithm.

[0012] This invention, used in a drilling company's drilling team, saves energy and avoids grid disruptions. Furthermore, because the solar photovoltaic panels are installed on the roof of the drilling camp, no additional hoisting or transportation costs are incurred during rig relocation. This invention leverages the significant advantages of clean, continuous, and safe solar photovoltaic power generation, reducing environmental pollution from fossil fuel combustion and lowering the drilling team's electricity costs. It also reduces drilling electricity costs, prevents damage to camp equipment caused by grid disruptions, and extends the lifespan of equipment within the drilling camp. By designing and installing solar photovoltaic panels on the drilling camp roof, and utilizing intelligent control inverters in conjunction with the drilling team's power grid, this invention maximizes the use of clean energy.

[0014] Appendix Figure 2 This is a functional block diagram of an embodiment of the present invention.

[0015] Appendix Figure 3 This is a schematic diagram showing the connection of the solar panel, the solar inverter, and the battery in an embodiment of the present invention.

[0016] The codes in the attached diagram are as follows: 1 represents the solar panel, 2 represents the integrated solar inverter, and 3 represents the battery. Detailed Implementation

[0017] The present invention is not limited to the following embodiments, and the specific implementation can be determined according to the technical solution of the present invention and the actual situation.

[0018] The present invention will be further described below with reference to embodiments: Example 1: As shown in the attached document Figure 1 , 2 As shown in Figure 3, the power supply device for the oil drilling camp includes a main power supply system and a solar power generation system, which are electrically connected by an automatic switching switch. The main power supply system includes diesel generator sets; The solar power generation system includes solar panels, a solar inverter / controller unit, and batteries. The solar panels and batteries are electrically connected to the solar inverter / controller unit.

[0019] In this embodiment, the main power supply system also includes a gas generator set and a municipal power grid, with the gas generator set, municipal power grid and diesel generator set serving as backups for each other.

[0020] This embodiment also includes an intelligent control system, which is electrically connected to the main power supply system and the solar power generation system, and is used to intelligently control the power supply of the oil drilling camp. Specifically, during the day, the camp uses the electricity stored in the main battery, and automatically switches to mains power when the main battery voltage is detected to be low; at night, the camp uses the electricity stored in the main battery, and automatically switches to the backup battery when the main battery voltage is detected to be low, and automatically switches to mains power when the backup battery voltage is low.

[0021] In this embodiment, a barracks power control unit is also included. This unit is located in the control box of each barracks and is used to individually control the power consumption of that barracks. Specifically, the power consumption detection program can be set with a maximum power load. When the power load reaches the maximum, the power is automatically cut off; when it falls below the maximum, the power is automatically restored. In this embodiment, the incoming and outgoing line plugs are plug-in connectors for quick plugging and unplugging during power use and disconnection.

[0022] In this embodiment, the integrated solar inverter controller incorporates an MPPT controller, which uses a maximum power point tracking algorithm to quickly and accurately locate the maximum power point of the photovoltaic cells. This allows for the acquisition of more photovoltaic energy, improving efficiency and reducing system costs. In this embodiment, the integrated solar inverter controller is based on multi-phase synchronous rectification technology and is suitable for off-grid photovoltaic systems.

[0023] In this embodiment, during the day when there is sufficient sunlight, the solar panels generate enough electricity to power the barracks' electrical equipment and charge the batteries. At night when there is insufficient sunlight, the solar panels generate insufficient electricity, and the batteries supply power to the household electrical equipment via the integrated inverter.

[0024] When in use, the drilling campsite primarily uses the main power supply system. During the day, it shares power with the solar power system, with priority given to solar energy. At night, it uses the main power supply system, and the battery provides short-term emergency power. The integrated solar inverter and battery can compensate for and absorb voltage surges, ensuring a stable power supply to the campsite.

[0025] This invention, used in a drilling company's drilling team, saves energy and avoids grid disruptions. Furthermore, because the solar photovoltaic panels are installed on the roof of the drilling camp, no additional hoisting or transportation costs are incurred during rig relocation. Utilizing the significant advantages of clean, continuous, and safe solar photovoltaic power generation, it not only reduces environmental pollution caused by fossil fuel combustion, protecting the environment, but also lowers the drilling team's electricity costs. It reduces drilling electricity costs, avoids grid disruptions that could damage equipment in the camp, and extends the lifespan of equipment within the drilling camp. This invention, through the design and installation of solar photovoltaic panels on the drilling camp roof, utilizes intelligent control inverters and the drilling team's power grid to provide power to the drilling camp, maximizing the use of clean energy.

[0026] In this embodiment, the solar power system provides a stable, clean, and high-quality power source for the barracks' electrical equipment. Its design must consider its advanced nature to ensure the system maintains technological leadership for a certain period, thereby guaranteeing its long lifespan. Wind load, temperature stress, and seismic effects are considered based on the engineering characteristics. The safety factor design should meet the engineering requirements.

[0027] In this embodiment, the power consumption and duration of electrical equipment in a single barracks each night are shown in Table 1.

[0028] In this embodiment, each solar panel has a power of 625W. Based on an average of 7 hours of sunshine per day, the solar power generation of the barracks is estimated as shown in Table 2.

[0029] In this embodiment, there are a total of 18 barracks, each with a solar panel power of 5KW. For 18 barracks, the total solar panel power is 18 * 5 = 90KW, resulting in a total solar panel power of 90KW. The hourly power generation is 90 kWh. Assuming 7 hours of sunshine per day, the daily power generation of the 18 barracks is 90 * 7 = 630 kWh. Each residential barracks consumes approximately 38 kWh per day, so for a total of 9 residential barracks, the daily power consumption is 9 * 38 = 342 kWh.

[0030] In this embodiment, 288 12V 200AH batteries can be configured in the battery room, storing a total of 691.2 kWh of electricity. Of these, 144 are primary batteries, used for charging the solar panels in the barracks, storing a total of 345.6 kWh, sufficient for the drilling team's power needs for one night. The other 144 batteries serve as backup batteries, charged by both solar and mains power. The backup batteries begin charging once the primary batteries are fully charged by the solar panels.

[0031] In this embodiment, the solar panel and battery are connected as a whole as follows: Figure 3 As shown, the solar panel is connected to 8 panels, with 2 panels connected in series to form 1 group, and 4 groups connected in parallel to 8 batteries connected in series.

[0032] In this embodiment, the configuration list for a single station is shown in Table 3.

[0033] In this embodiment, there are two operating modes: reverse priority mode and power supply priority mode. In reverse priority mode, when the battery voltage is normal, the inverter operates in reverse mode, and the load power is supplied by the battery in reverse. If the battery is fully charged by solar or wind power via the controller, the system will automatically switch to battery power supply mode. When the inverter operates in power supply mode, the battery can also be charged, which is determined by the charging current mode setting. If charging is not required, the charging current can be 0A. In power supply priority mode, when the load is powered by the power supply, the power supply must pass through the input protection device and be filtered before supplying power to the load to ensure power stability. The battery can also be charged (determined by the charging mode). When the power supply is interrupted or abnormal, the system automatically switches to battery power supply mode; when the power supply is normal, the system automatically switches to power supply mode to supply power to the load.

[0034] In this embodiment, the specifications of the solar inverter integrated machine are shown in Table 4.

[0035] In this embodiment, the battery specifications are shown in Table 5.

[0036] In this embodiment, the specifications of the solar panel are shown in Table 6.

[0037] In this embodiment, the distribution box includes an indoor cabinet and an outdoor cabinet. The indoor cabinet is a system integrating AC power distribution and auxiliary equipment, specifically designed for placing the entire solar power generation system directly outdoors. The outdoor cabinet features flexible relocation, convenient transportation, and rapid construction, reducing building and maintenance costs and shortening the construction cycle. It can adopt a modular design, flexibly combine, and expand side-by-side or back-to-back. Its large casing capacity ensures a neat and aesthetically pleasing site, supporting both overall and component transport. The specifications of the distribution box are shown in Table 7.

[0038] In this embodiment, when maintaining the solar panels and brackets, keep the surface of the solar panels clean. In areas with little rain and high winds, clean the solar panels monthly. Rinse with clean water and then wipe with a clean, soft cloth. Do not use corrosive solvents or abrasive materials. Cleaning should be done in the morning or evening, away from direct sunlight. Do not wash the solar panels with cold water when they are heated by the sun during the day. Check if the bolts on the side clips and center clips of the solar panels are loose. If so, tighten them immediately. After a strong wind, check if the solar panels are loose. Check if the connecting wires between the solar panels are secure and if the connecting wires of the photovoltaic junction box are secure as required. If so, tighten them. Check the solar panels for damage or abnormalities, such as damage or hot spots. If the solar panels malfunction, replace them promptly. Record the installation location of the solar panels in detail. Check if the solar panel bracket connections are secure and if the bolts are loose. If so, tighten them immediately. Check the metal brackets of the solar array for corrosion and scratches on the galvanized layer. If so, repaint and apply anti-corrosion treatment promptly. Check the grounding wire of the solar array for any loose connections and ensure proper grounding. If the grounding wire is aged, replace it promptly. Check if the surge arrester in the junction box is malfunctioning. If so, replace it. Check if the surge arrester in the junction box is reliably grounded.

[0039] In this embodiment, when maintaining the battery, check if the battery surface is clean and free from corrosion or leakage. If there is more dirt on the casing, wipe the battery with a damp cloth, taking care not to touch the battery terminals to avoid electric shock. Check if the battery is dented or swollen. If so, replace the battery as soon as possible. Tighten the battery connection screws at least every six months to ensure a good connection. When repairing or replacing the battery, tools must be covered with an insulated cover to prevent short circuits. Charge the battery immediately after discharging. If continuous rain causes insufficient battery charging, reduce the load power and control the power supply time to avoid over-discharging the battery. If the battery has been stored for more than 3 months, charge it before operation. If the system is not used for a long time, disconnect the circuit breaker between the battery and the control inverter to prevent the control inverter from over-discharging the battery due to prolonged standby power consumption. The battery must be maintained once or twice a year, mainly by measuring and recording the battery voltage and internal resistance, and comparing the measured data with the original data. If an increase in the difference between batteries in some units is found, the battery must be replaced in time.

[0040] In this embodiment, when maintaining the integrated control inverter, check whether the connections between the controller, inverter, and other equipment are secure, and whether the grounding cable connection is secure. Check whether the controller's operating parameters are consistent with the design values; if not, adjust the parameters as needed. Check whether the controller's displayed values ​​are consistent with the actual measured values ​​to verify whether the controller is functioning properly.

[0041] The above technical features constitute the embodiments of the present invention, which have strong adaptability and implementation effect. Unnecessary technical features can be added or removed according to actual needs to meet the needs of different situations.
