Description

Technical Field

[0001] The present invention relates to the technical field of hydraulic generators, and in particular to an intelligent hydraulic power generation device and system for deep-sea oil drilling. Background Art

[0002] The application prospects of hydraulic generators in deep-sea oil drilling are relatively broad. In deep-sea environments, traditional power supply methods, such as relying on sea-surface platforms to transmit electricity or using independent power generation equipment, may be affected by various factors, resulting in unstable power supply. Hydraulic generators, as backup or auxiliary power sources, can provide timely power support when problems occur in the main power supply to ensure the operation of key equipment. From a long-term operation perspective, hydraulic generators can significantly reduce mining costs by recycling energy and reducing external energy consumption. The power of hydraulic generators comes from the flow of drilling mud. In the actual drilling process, the mud flow rate will fluctuate frequently due to factors such as formation characteristics and drill bit conditions, affecting the normal operation of electrical equipment on board and may even damage precision instruments. In addition, in the complex deep-sea environment, the energy conversion efficiency of hydraulic generators is difficult to maintain constant. Changes in environmental factors such as temperature and pressure, as well as wear and aging of the equipment itself, will lead to changes in turbine efficiency, hydraulic transmission efficiency and generator power generation efficiency, further exacerbating the instability of power output and increasing the difficulty of maintaining a stable power supply.

[0003] Chinese patent publication number: CN105736216B discloses a device for generating electricity by utilizing formation pressure energy during oil drilling and transmitting residual pressure energy, including: a device for generating electricity by utilizing formation pressure energy, including a single-inlet and double-outlet speed tuning valve and a speed control linkage actuator, a filtering and separating buffer, a multi-head spiral plate centrifugal impeller rotor type gas-liquid phase turbine, a high back pressure natural gas turbine and two generators; and a device for generating electricity by utilizing residual pressure energy, including a piston-type single-stroke natural gas engine unit and a piston-type two-stroke natural gas engine unit connected in parallel to the high-pressure gas outlet from the upper station. This scheme only discusses how to generate electricity by utilizing the power source generated during oil drilling, and does not take into account the situation of unstable power output, and cannot be applied to situations such as deep-sea oil drilling that have high requirements for power stability and harsh operating environments. Summary of the invention

[0004] To this end, the present invention provides an intelligent hydraulic power generation device and system for deep-sea oil drilling, so as to overcome the problem of low power stability caused by the difficulty in maintaining constant energy conversion efficiency of hydraulic generators in deep-sea oil drilling environments in the prior art.
