[0023] like Figure 1 As shown, this embodiment illustrates the skid-mounted modular logging winch system based on an ultra-deep well (10,000 meters). The system comprises four independent and detachable modules: a generator module 1, a hydraulic power module 2, an operation control module 3, and a logging winch module 4. Each module is quickly connected and disconnected via standardized interfaces, thus meeting the high efficiency and high reliability requirements of logging operations in ultra-deep wells (10,000 meters). The specific structure, connection methods, operation steps, and multi-scenario applications of each module will be described in detail below.
[0024] Each module has the same width and height, while its length is adjusted according to the layout. Electrical control signals between modules are connected via signal cables with quick-connect connectors. Adjacent modules are connected via standard corner brackets and bridge brackets (including the top and bottom). Each module is designed as a skid-mounted structure, with lifting lugs on each skid for easy lifting and transportation, suitable for rapid deployment in oil and gas fields. The external structure of the module uses a steel frame, providing resistance to pressure, shock, and corrosion.
[0025] The generator set module 1 includes a skid, a diesel tank 7, a diesel generator 5, a generator 5 voltmeter, a power control box 6, and connecting wiring harnesses, etc.
[0026] The hydraulic power module 2 is equivalent to a high-power power unit, which includes a skid, radiator 12, electric motor 9, hydraulic oil pump 11, hydraulic oil tank 10, connecting wiring harness, etc.
[0027] The operation control module 3 is the centralized control console 15 for the entire set of equipment, including the skid, the centralized control console 15, the electrical monitoring room, and the connecting harness.
[0028] The logging winch module 4 is the actuator, which includes a skid, logging winch 17, hydraulic motor 16 and connecting harness, etc. The 10,000-meter logging winch 17 adopts an integral hoisting structure.
[0029] All components of the above four main modules have standard connection interfaces, and the electrical wiring harnesses and hydraulic and gas pipelines are all standard quick-connect connectors, allowing for quick replacement of any faulty component.
[0030] Generator module 1 provides power to the entire equipment; hydraulic power module 2 converts electrical energy into hydraulic energy to provide hydraulic power to logging winch module 4; operation control module 3 is the centralized control area for logging operations and provides a workspace for operators; logging winch module 4 is the logging operation execution module, which drives hydraulic motor 16 to rotate via electric motor 9, and hydraulic motor 16 drives logging winch 17 to work; the connections between modules are all standardized interfaces, and any module failure can be quickly replaced as a whole to ensure continuous operation of the equipment.
[0031] Generator module 1 is the core of the power supply for the entire logging winch system. The diesel generators in generator module 1 generate electricity to provide power for the entire equipment. The power output harness quick-connect connector is reserved on the power socket box 8. When the grid power is available at the well site, the grid power provides power to the other modules. Generator module 1 can be used as a backup or for other well sites.
[0032] The diesel generator 5 in generator module 1 is a high-power generator, and its output power can be dynamically adjusted according to the load requirements of the logging operation. The electrical energy output by generator 5 is regulated by power control box 6 to ensure a stable 380V three-phase AC power supply for hydraulic power module 2 and operation control module 3.
[0033] To improve on-site wiring efficiency, generator module 1 is equipped with a quick-plug power connector. The power output harness connects to the power junction box 8, allowing on-site operators to connect the power supply simply by plugging and unplugging the connector. Simultaneously, when the well site grid power is available, generator module 1 can switch to standby mode, achieving a seamless transition through an internal switch to avoid operational interruptions.
[0034] The electric motor 9 in the hydraulic power module 2 converts electrical energy into mechanical energy, driving the hydraulic oil pump 11 to generate hydraulic energy. The electric motor 9 uses a control harness and is pre-installed on the signal control box 13 via a quick plug. The oil output port of the hydraulic oil pump 11 is connected to the combination valve plate 14 via a hydraulic quick plug. The power input harness quick-connect connector is connected to the power socket box 8.
[0035] The electric motor 9 is connected to the centralized control console 15 of the operation control module 3 via a control harness, enabling precise regulation of the hydraulic output flow and pressure. All hydraulic lines within the module utilize quick-connect couplings, allowing connection or disconnection to be completed within seconds, reducing on-site wiring time.
[0036] The oil output ports of the hydraulic oil pump 11 and the hydraulic motor 16 are connected to the inside of the hydraulic oil tank 10. The hydraulic oil tank 10 has a built-in liquid level monitoring device and a temperature sensor, which can provide real-time feedback on the oil status to the operation control module 3. When the liquid level is insufficient or the temperature is abnormal, a warning signal is issued to facilitate timely maintenance.
[0037] Both generator module 1 and hydraulic power module 2 are equipped with power socket boxes 8. The output end of generator 5 and the input end of motor 9 are connected to the power socket boxes 8 in the corresponding modules using quick-plug power connectors. The power socket boxes 8 are connected to each other using shielded cables.
[0038] The operation control module 3 is the command center of the entire system, and its main function is to centrally control various operations of the logging operation. The operation control module 3 is equipped with a winch control console, and the module is equipped with a complete set of control components. The control wiring harness is reserved on the signal control box 13 via a quick connector.
[0039] The centralized control console 15 integrates operating interfaces for power monitoring, hydraulic control, and winch control, and uses an industrial-grade PLC (Programmable Logic Controller) for signal processing and feedback monitoring. Operators can use the centralized control console 15 to monitor key parameters in real time, such as the operating status of the logging winch 17, hydraulic pressure, and the power output of the five generator sets.
[0040] In terms of module design, shielded cables and quick connectors are used for the transmission of control signals to reduce electromagnetic interference and improve connection efficiency. The control wiring harness is pre-installed on the signal control box 13, and connection is simply a matter of inserting the corresponding connector.
[0041] The hydraulic motor 16 in the logging winch module 4 can convert hydraulic energy into mechanical energy and drive the logging winch 17 to rotate forward and backward through the transmission mechanism. The control harness of the hydraulic motor 16 is reserved on the signal control box 13 through a quick plug, and the oil input port of the hydraulic motor 16 is reserved on the combination valve plate 14 through a quick plug.
[0042] The logging winch 17 uses high-strength steel wire rope, which is wear-resistant and corrosion-resistant, and can withstand the operational requirements of long-distance downhole exploration.
[0043] Both the hydraulic power module 2 and the logging winch module 4 are equipped with a combined valve plate 14. The oil output ports of the hydraulic oil tank 10, the hydraulic oil pump 11, and the hydraulic motor 16 are all connected to the combined valve plate 14 by hydraulic quick plugs. The combined valve plates 14 are connected to each other by hydraulic hoses.
[0044] The hydraulic power module 2, operation control module 3, and logging winch module 4 are all equipped with signal control boxes 13. The control harnesses of the central control console 15, electric motor 9, hydraulic motor 16, and logging winch 17 are all connected to the corresponding signal control boxes 13 in the module using quick connectors. The signal control boxes 13 are connected to each other using shielded cables.
[0045] The modules are fixedly connected using standard corner brackets and bridge brackets, with reinforcement at both the top and bottom to ensure mechanical strength and stability. Electrical control signals are connected via quick-connect signal cables, and hydraulic lines also use quick-connect couplings, reducing the complexity of traditional threaded connections.
[0046] During on-site installation, the generator module 1, hydraulic power module 2, operation control module 3, and logging winch module 4 are connected sequentially, with power harnesses, control harnesses, and hydraulic lines connected using standardized interfaces. The modular design allows for rapid replacement of any faulty module without disassembling other modules. This significantly reduces downtime, improves operational efficiency, and adapts to rapid recovery needs in various environments.
[0047] Before logging operations, reliably connect the hydraulic power module 2, operation control module 3, logging winch module 4, and generator module 1 using the corner fittings on each module skid; connect the power harness between generator module 1 and hydraulic power module 2; connect the control harness between hydraulic power module 2 and operation control module 3; connect the control harness between logging winch module 4 and operation control module 3; connect the hydraulic pipeline between hydraulic power module 2 and logging winch module 4; once the entire set of equipment is connected, logging operations can begin.
[0048] The modular design allows for separate hoisting and transportation of the equipment, which better meets the hoisting and transportation requirements of onshore oil and gas fields and offshore platforms. In addition, the weight limitations of the logging winch module 4 are partially alleviated, making it easier to implement the skid-mounted design of the 17 logging winch for ultra-deep wells at depths of 10,000 meters.
[0049] The modular design, coupled with standardized quick-swap connections between modules, allows for rapid replacement of any faulty module, ensuring uninterrupted logging operations and thus guaranteeing the stability and reliability of critical projects such as 10,000-meter wells.
[0050] The modular design allows for the creation of complete solutions for various application scenarios. For example, the 10,000-meter logging winch module 4 (with the 10,000-meter logging winch 17 installed) is matched with the hydraulic power module 2, operation control module 3, and generator set module 1 to form a system for 10,000-meter logging; the perforation double-drum logging winch module 4 (with the coaxial double-drum logging winch 17 installed) is matched with the hydraulic power module 2, operation control module 3, and generator set module 1 to form a system for perforation operations. The logging winch module 4 is flexible in configuration, not only widely applicable but also reducing equipment idle time and lowering equipment costs.
[0051] When the grid power at the well site is available, only the hydraulic power module 2, operation control module 3, and logging winch module 4 are needed to complete the logging operation, while generator module 1 can be kept on standby, which meets the requirements of green oil and gas fields.
