Description

Technical Field

[0001] This disclosure relates to the field of oil and gas field cementing technology, specifically to a drive control method and device for cementing equipment. Background Technology

[0002] Cementing equipment is typically driven by diesel, hydraulic, or electric motors. Diesel-driven cementing equipment requires a high-power engine, which leads to power waste and higher operating costs in low-power operation conditions, as well as pollution and noise. Hydraulic-driven cementing equipment has low transmission efficiency, high fuel consumption for the same power, and is prone to hydraulic oil leakage, which can easily cause environmental pollution. Electric-driven cementing equipment is low-cost, has high transmission efficiency, and is less polluting and more environmentally friendly. However, the high power consumption of electric-driven cementing equipment can cause power anxiety during operation, affecting the working effect and efficiency of the cementing equipment. Summary of the Invention

[0003] The purpose of this disclosure is to provide a drive control method and apparatus for cementing equipment, so as to at least solve the technical problems existing in the prior art, such as power anxiety in electric cementing equipment, which affects the operation effect and efficiency of cementing equipment, as well as the high operation cost, low transmission efficiency, high pollution and high noise of existing cementing equipment.

[0004] To solve the above-mentioned technical problems, the embodiments of this disclosure adopt the following technical solutions:

[0005] In a first aspect, embodiments of this disclosure provide a drive control method for a cementing device, the cementing device including a drive unit, a load unit, and a control unit, the drive unit including a power generation system and an energy storage system, the method being applied to the control unit, including:

[0006] Determine whether the energy storage system meets the operating power consumption of the load unit;

[0007] If the conditions are met, the energy storage system is controlled to supply power to the load unit; if the conditions are not met, the power generation system is controlled to supply power to the load unit according to the total load power of the load unit, or the energy storage system and the power generation system are controlled to supply power to the load unit.

[0008] In some embodiments, if the energy storage system does not meet the operating power consumption of the load unit, the power generation system is controlled to supply power to the load unit according to the total load power of the load unit, or the energy storage system and the power generation system are controlled to supply power to the load unit, including:

[0010] If yes, control the energy storage system and the power generation system to supply power to the load unit; if no, control the power generation system to supply power to the load unit.

[0011] In some embodiments, if the total load power is greater than the total power of the power generation system, the method further includes:

[0013] If not needed, control the energy storage system and the power generation system to supply power to the load unit; if needed, control the power generation system to charge the energy storage system.

[0014] In some embodiments, after controlling the power generation system to charge the energy storage system, the method further includes:

[0016] If fully charged, control the energy storage system and the power generation system to supply power to the load unit.

[0017] In some embodiments, if the total power of the load is less than the total power of the power generation system, when supplying power to the load unit through the power generation system, the method further includes:

[0018] Detect whether the discharge depth of the energy storage system has reached a preset depth threshold;

[0019] If yes, control the power generation system to supply power to the load unit and control the power generation system to charge the energy storage system; if no, control the energy storage system to supply power to the load unit, and when the discharge depth of the energy storage system reaches the preset depth threshold, control the power generation system to supply power to the load unit and control the power generation system to charge the energy storage system.

[0020] In some embodiments, the method further includes:

[0021] The power generation system is controlled to start or stop discharging based on the charging status of the energy storage system.

[0022] In some embodiments, the method further includes:

[0023] Determine whether an external power source can be used at the well site;

[0024] If an external power source is available, determine whether it is an external power source based on its power rating; if an external power source is not available, control the energy storage system to supply power to the load unit.

[0025] In some embodiments, determining whether an external power source is connected based on its power characteristics includes:

[0026] Determine whether the power of the external power supply meets the total load power of the load unit;

[0027] If the power of the external power supply meets the total load power of the load unit, the external power supply is controlled to supply power to the load unit; if the power of the external power supply does not meet the total load power of the load unit, the external power supply and the energy storage system are controlled to supply power to the load unit.

[0028] Secondly, embodiments of this disclosure provide a drive control device for cementing equipment. The cementing equipment includes a drive unit, a load unit, and the drive control device. The drive unit includes a power generation system and an energy storage system. The drive control device includes:

[0029] The judgment module is configured to: determine whether the energy storage system meets the operating power consumption of the load unit;

[0030] The control module is configured to: if the energy storage system meets the operating power consumption of the load unit, control the energy storage system to supply power to the load unit; if the energy storage system does not meet the operating power consumption of the load unit, control the power generation system to supply power to the load unit according to the total load power of the load unit, or control the energy storage system and the power generation system to supply power to the load unit.

[0033] This disclosure provides a drive control method and apparatus for cementing equipment. The control unit first determines whether the energy storage system in the drive unit meets the power consumption of the load unit. If it does, the control unit controls the energy storage system to supply power to the load unit. If not, the control unit controls the power generation system to supply power to the load unit based on the total load power of the load unit, or controls both the energy storage system and the power generation system to supply power to the load unit. This allows for selection of the appropriate power supply mode based on the load unit's power consumption, ensuring timely and effective startup of the load unit, avoiding power anxiety during electric cementing equipment operation, improving the reliability of the load unit, ensuring the cementing equipment's operational effectiveness, and effectively reducing power consumption and the cost of electric drive for the cementing equipment. In this embodiment, priority is given to determining whether the energy storage system can supply power independently, allowing for priority use of the stored energy to improve the startup efficiency of the load unit and the operational efficiency of the cementing equipment. Furthermore, the selective power supply from the energy storage system and the power generation system enables electric drive of the cementing equipment even in well sites without a power grid, and the diverse electric drive methods effectively broaden the applicability of the cementing equipment. Cementing equipment using the above-mentioned drive control method effectively reduces operating costs, improves operational transmission efficiency, and is less polluting, less noisy, and more environmentally friendly.

[0047] This specification may use the phrases “in one embodiment,” “in another embodiment,” “in yet another embodiment,” or “in other embodiments,” all of which may refer to one or more of the same or different embodiments according to this disclosure.

[0048] Figures 1 to 4 A flowchart illustrating the drive control method for cementing equipment according to an embodiment of this disclosure is shown. Figures 1 to 4 As shown in the embodiments of this disclosure, a drive control method for a cementing device is provided. The cementing device includes a drive unit, a load unit, and a control unit. The drive unit includes a power generation system and an energy storage system. The method is applied to the control unit and includes:

[0049] S101: Determine whether the energy storage system meets the operating power consumption of the load unit;

[0050] S1021: If satisfied, control the energy storage system to supply power to the load unit; S1022: If not satisfied, control the power generation system to supply power to the load unit according to the total load power of the load unit, or control the energy storage system and the power generation system to supply power to the load unit.

[0051] Specifically, the drive unit is a power supply unit, including a power generation system and an energy storage system, used to supply power to the load unit, thereby driving the load unit to operate and achieve cementing. The load unit mainly includes a pumping system and a mixing system. The pumping system mainly includes an electric motor and a plunger pump. The electric motor is connected to both the drive unit and the plunger pump. The drive unit supplies power to the electric motor, driving it to operate, which in turn drives the plunger pump to perform pumping operations. The mixing system is connected to the pumping system through a manifold. The mixing system mainly includes an electric motor, a centrifugal pump (including a water centrifugal pump and a mud centrifugal pump), a mixing tank, and an agitator. The electric motor is connected to both the drive unit and the centrifugal pump. The drive unit supplies power to the electric motor, driving it to operate, which in turn drives the centrifugal pump to operate, providing the mixed cement slurry to the pumping system. The agitator can be driven by an electric motor or a hydraulic motor. When the agitator is driven by a hydraulic motor, an electric motor can drive a hydraulic pump, which in turn drives a hydraulic motor, which in turn drives the agitator. The drive unit supplies power to the electric motor, thus achieving electric drive of the agitator.

[0052] The control unit is connected to the drive unit via a cable and is used to control the drive unit's power supply. The drive unit includes three power supply modes: energy storage system power supply mode, power generation system power supply mode, and a combined energy storage and power generation system power supply mode. The control unit can selectively switch the power supply mode according to the load unit's operating power consumption to provide precise power to the load unit.

[0053] An energy storage system is a unit capable of storing electrical energy and releasing it when needed. An energy storage system includes a battery pack. The battery pack adopts a modular design, consisting of several batteries connected in series and parallel, used to power load units. The control unit includes a battery management system, which measures basic parameters of the battery pack such as voltage, current, and temperature, prevents overcharging and over-discharging, calculates and analyzes the remaining battery capacity and battery health status, and promptly reports abnormal information to extend battery life.

[0054] In addition to battery packs as described above, energy storage systems can also be configured with supercapacitors. Supercapacitors, replacing battery packs, possess the characteristics of high-current, rapid charging and discharging, enabling power surge compensation for load units such as pumping systems and improving the stability of these load units.

[0055] The power generation system includes an engine and a generator, with the engine connected to the generator and the generator connected to a load unit. The engine provides mechanical power to the generator, which converts the mechanical energy into electrical energy and supplies the electrical energy to the load unit, enabling the load unit to operate electrically.

[0056] The engine is a diesel engine or other power source. When the engine is a diesel engine, it converts the energy from the combustion of diesel fuel into mechanical energy, which is then transferred to the generator and converted into electrical energy. There must be at least one engine and one generator. Multiple generators can be connected to a parallel power supply cabinet to supply power to the load unit. The control unit includes a generator control system, which is connected to both the engine and the generator. The generator control system can control the engine to perform functions such as start-up, shutdown, data measurement, data display, and fault protection. It can also control the generator to perform functions such as power measurement, power display, and power protection.

[0057] In this embodiment, when selecting the power supply mode, the control unit first determines in step S101 whether the discharge capacity of the energy storage system meets the operating power consumption of the load unit. If the discharge capacity of the energy storage system is greater than the operating power consumption of the load unit, it is determined that the discharge capacity of the energy storage system meets the operating power consumption of the load unit. Power is then supplied to the load unit directly through the discharge of the battery pack and / or supercapacitor of the energy storage system, driving the load unit to perform cementing operations. After supplying power to the load unit through the discharge of the energy storage system, the energy storage system can be recharged after the load unit's operation is completed for subsequent use.

[0058] The energy storage system includes a charging module, which mainly comprises a current-limiting module and a rectifier module. The AC power entering from the charging module's input is converted into DC power by the current-limiting and rectifier modules to supply power to the battery pack. In practice, the energy storage system can be charged by a generator system or by an external power source such as an external charging pile.

[0059] If the discharge of the energy storage system is less than or equal to the operating power consumption of the load unit, it is determined that the discharge of the energy storage system does not meet the operating power consumption of the load unit and may not be able to effectively drive the load unit to operate. In this case, it can be determined based on the total load power of the load unit whether to use the power generation system to supply power to the load unit alone or to use the energy storage system and the power generation system to supply power to the load unit together.

[0060] The drive control method for cementing equipment provided in this embodiment first determines whether the energy storage system in the drive unit meets the power consumption of the load unit. If it does, the control unit controls the energy storage system to supply power to the load unit. If not, the control unit controls the power generation system to supply power to the load unit based on the total load power of the load unit, or controls both the energy storage system and the power generation system to supply power to the load unit. This method can select the corresponding power supply mode based on the power consumption of the load unit, ensuring timely and effective start-up of the load unit, avoiding power anxiety during the operation of the electrically driven cementing equipment, improving the reliability of the load unit, ensuring the operational effect of the cementing equipment, and effectively reducing power consumption and the cost of electric drive for the cementing equipment. In this embodiment, priority is given to determining whether the energy storage system can supply power independently, and the stored energy can be used to supply power, improving the start-up efficiency of the load unit and the operational efficiency of the cementing equipment. In addition, through the selective power supply of the energy storage system and the power generation system, the cementing equipment can be electrically driven even in well sites without power grids, and the electric drive mode is diverse, effectively improving the applicability of the cementing equipment. Cementing equipment using the above-mentioned drive control method effectively reduces operating costs, improves operational transmission efficiency, and is less polluting, less noisy, and more environmentally friendly.

[0061] In some embodiments, such as Figure 2 and Figure 4 As shown, in step S1022, if the energy storage system does not meet the operating power consumption of the load unit, the power generation system is controlled to supply power to the load unit according to the total load power of the load unit, or the energy storage system and the power generation system are controlled to supply power to the load unit, including:

[0062] S201: Determine whether the total power of the load is greater than the total power of the power generation system;

[0063] S2021: If yes, control the energy storage system and the power generation system to supply power to the load unit; S2022: If no, control the power generation system to supply power to the load unit.

[0064] When the discharge capacity of the energy storage system is less than or equal to the operating power consumption of the load unit, relying solely on the energy storage system for power supply may not be sufficient to control the start-up and operation of the load unit. In this case, the power supply method can be selected based on the relationship between the total load power of the load unit and the total power of the power generation system.

[0065] If the total load power exceeds the total power of the power generation system, relying solely on the power generation system may not be sufficient to effectively start and operate the load unit. In this case, the control unit can select a combined power supply mode for the energy storage system and the power generation system, controlling both systems to supply power to the load unit. If the total load power is less than or equal to the total power of the power generation system, the power generation system alone can provide sufficient electrical energy to the load unit. In this case, the control unit selects the power generation system as the sole power supply mode, using only the power generation system to supply power to the load unit.

[0066] In some embodiments, such as Figure 2 and Figure 4 As shown, if it is determined through step S301 that the total load power is greater than the total power of the power generation system, the method further includes:

[0067] S301: Detect whether the energy storage system needs charging;

[0068] S3021: If not needed, control the energy storage system and the power generation system to supply power to the load unit; S3022: If needed, control the power generation system to charge the energy storage system.

[0069] When the total power of the load unit is greater than the total power of the power generation system, in order to ensure the reliable operation of the energy storage system and the power generation system in the common power supply mode (when the energy stored in the energy storage system is insufficient, even the common power supply mode of the energy storage system and the power generation system cannot provide sufficient power), before adopting the common power supply mode of the energy storage system and the power generation system, step S401 is used to detect whether the energy storage system needs to be charged (whether the discharge capacity of the energy storage system is sufficient). If the sum of the discharge capacity of the energy storage system and the power generation capacity of the power generation system is greater than the operating power consumption of the load unit, it is determined that the discharge capacity of the energy storage system is sufficient. At this time, there is no need to charge, and step S3021 is executed to provide power to the load unit by discharging the energy storage system and the power generation system simultaneously. If the sum of the discharge of the energy storage system and the power generation of the power generation system is less than or equal to the operating power consumption of the load unit, it is determined that the discharge of the energy storage system may be insufficient and needs to be charged. At this time, the control unit can execute step S3022 to control the power generation system to generate electricity, first charging the energy storage system unit. Then, when the sum of the discharge of the energy storage system and the power generation of the power generation system is at least greater than the operating power consumption of the load unit, step S3021 is executed to supply power to the load unit by discharging the energy storage system and the power generation system simultaneously.

[0070] In some embodiments, such as Figure 2 and Figure 4 As shown, after controlling the power generation system to charge the energy storage system, the method further includes:

[0071] S401: Detect whether the energy storage system is fully charged;

[0072] S4021: If fully charged, control the energy storage system and the power generation system to supply power to the load unit.

[0073] Since the energy storage system's electrical capacity is predetermined, in this embodiment, the sum of the energy storage system's discharge and the power generation of the generator system can be directly determined by detecting whether the energy storage system is fully charged. This detection is convenient and quick. If fully charged, it is determined that the sum of the energy storage system's discharge and the generator system's power generation meets the load unit's operating power consumption, and the load unit can be powered using a combined power supply mode of the energy storage system and the generator system. After power supply is completed, there may be residual energy in the energy storage system for reuse.

[0074] In other embodiments, if the energy storage system has a large power capacity, the required charging amount of the energy storage system can be calculated in real time based on the power generation of the power generation system and the power consumption of the load unit, thereby providing a more accurate discharge amount of the energy storage system.

[0075] In some embodiments, such as Figure 2 and Figure 4 As shown, if the total power of the load is less than the total power of the power generation system, when supplying power to the load unit through the power generation system, the method further includes:

[0076] S501: Detect whether the discharge depth of the energy storage system has reached a preset depth threshold;

[0077] S5021: If yes, control the power generation system to supply power to the load unit and control the power generation system to charge the energy storage system; S5022: If no, control the energy storage system to supply power to the load unit, and when the discharge depth of the energy storage system reaches the preset depth threshold, control the power generation system to supply power to the load unit and control the power generation system to charge the energy storage system.

[0078] When the power generation system is used for power supply, the control unit can detect whether the discharge depth of the energy storage system has reached a set value. If it has, it is determined that the energy storage system does not store enough electrical energy. At this time, in step S5021, while the power generation system supplies power to the load unit, the excess electrical energy generated by the power generation system can be used to charge the energy storage system. If the discharge depth has not reached the set value, it is determined that the energy storage system stores enough electrical energy. At this time, the energy storage system can discharge to supply power to the load unit. When the discharge depth of the energy storage system reaches the preset depth threshold, the power generation system is started to supply power to the load unit. While the power generation system supplies power to the load unit, the excess electrical energy is used to charge the energy storage system.

[0079] Furthermore, when controlling the power generation system to charge the energy storage system through step S5021 or S5022, the method further includes:

[0080] The power generation system is controlled to start or stop discharging based on the charging status of the energy storage system.

[0081] Specifically, such as Figure 2 and Figure 4 As shown, when the power generation system charges the energy storage system through step S5021, the control unit can monitor the charging status of the energy storage system in real time. After the energy storage system is fully charged, the control unit can control the power generation system to shut down, and the energy storage system will discharge to supply power to the load unit. When the energy storage system discharges to supply power to the load unit, the control unit can monitor the discharge depth of the energy storage system in real time. When the discharge depth of the energy storage system reaches the preset depth threshold, the power generation system is started to supply power to the load unit. At the same time, the excess electricity generated by the power generation system charges the energy storage system. In this way, the energy storage system and the power generation system can be cyclically supplied, realizing the effective utilization of electrical energy, improving power supply efficiency, ensuring the continuous and stable operation of the load unit, and improving the cementing effect.

[0082] Similarly, when the power generation system charges the energy storage system through step S5022, the control unit can monitor the charging status of the energy storage system in real time. After the energy storage system is fully charged, the control unit can control the power generation system to shut down, and the energy storage system will discharge to supply power to the load unit. In this way, the energy storage system and the power generation system can be used for cyclical power supply.

[0083] In some embodiments, such as Figure 3 and Figure 4 As shown, the method further includes:

[0084] S601: Determine whether an external power supply can be used at the well site;

[0085] S6021: If an external power supply can be used, determine whether to use the external power supply based on its power rating; S6022: If an external power supply cannot be used, control the energy storage system to supply power to the load unit.

[0086] If a power grid is installed at the well site, it is determined whether an external power source can be used. If an external power source is available, its power capacity can be assessed to determine whether it should be used, thus fully utilizing the well site's power grid. If an external power source is not available, the energy storage system is controlled to discharge and supply power to the load unit. After the energy storage system supplies power to the load unit, the energy storage unit is charged via the external power source or a generator system. The well site power supply converts AC to DC power through a transformer and rectifier module to power the load unit and the energy storage unit. This embodiment provides an external power supply mode to offer diverse power supply options for the load unit, improving power supply efficiency and effectiveness.

[0087] like Figure 4 As shown, step S601 above determines whether an external power source can be used at the well site. This can be performed after determining whether the energy storage system meets the operating power consumption of the load unit in step S101. When the operating power consumption of the load unit is less than the discharge capacity of the energy storage system, i.e., the operating power of the load is relatively low, the energy storage system can be directly used to discharge and supply power to the load unit. After the operation, the energy storage system can be recharged. When the operating power consumption of the load unit is greater than or equal to the discharge capacity of the energy storage system, step S601 determines whether an external power source can be used at the well site. If an external power source can be used, the decision to use the external power source is based on its power rating.

[0088] like Figure 4 As shown, when the operating power consumption of the load unit is less than the discharge capacity of the energy storage system, that is, when the energy storage system power supply mode is selected and the external power supply is available, it can be determined whether to use the external power supply through step S6021.

[0089] Furthermore, such as Figure 3 and Figure 4 As shown, in step S6021, determining whether to use the external power supply based on its power rating includes:

[0090] S701: Determine whether the power of the external power supply meets the total load power (operating power) of the load unit;

[0091] S7021: If the power of the external power supply meets the total load power of the load unit, control the external power supply to supply power to the load unit; if the power of the external power supply does not meet the total load power of the load unit, control the external power supply and the energy storage system to supply power to the load unit.

[0092] If the external power supply power is greater than the total load power of the load unit, then the external power supply power meets the total load power of the load unit, and the load unit can be powered by the external power supply alone. If the external power supply power is less than or equal to the total load power of the load unit, then the external power supply power does not meet the total load power of the load unit, and the load unit cannot be powered by the external power supply alone. In this case, the control unit can provide a power supply mode of external power supply and energy storage system, so as to improve the power supply effect and power supply efficiency by supplying power to the load unit together through the external power supply and the energy storage system.

[0093] In the above embodiments, the power supply parameters such as the number of generators in the power generation system and the capacity of the battery pack in the energy storage system can be pre-evaluated and matched according to the displacement (e.g., the pumping flow rate of the plunger pump) and pressure conditions of each load element in the load unit. The control unit dynamically adjusts the power supply mode according to the load power and power consumption of each load element in the load unit to achieve dynamic and stable power supply for cementing operations and to achieve optimal economy for cementing operations.

[0094] Figure 5 A schematic diagram of the drive control device for a cementing apparatus according to an embodiment of this disclosure is shown. Figure 5 As shown, based on the above-described drive control method for cementing equipment, this disclosure provides a drive control device for cementing equipment. The cementing equipment includes a drive unit, a load unit, and the drive control device. The drive unit includes a power generation system and an energy storage system. The drive control device includes:

[0095] The judgment module 10 is configured to determine whether the energy storage system meets the operating power consumption of the load unit;
