Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing oil-gas field fracturing operations face inefficiencies due to the reliance on single power supply systems, which lead to low electricity usage efficiency, high energy consumption during idle periods, and inability to handle fluctuating high-power loads.
Innovation Solution
Implementing a pumping system powered by multiple power supply systems, including a main power supply and an auxiliary power supply, to ensure continuous and efficient electricity delivery during fracturing operations, even during intervals and in case of main power supply failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a single power supply system is used to supply electric power to the electric fracturing device, then the system structure is simple, but the reliability of continuous operation is insufficient and electricity usage efficiency is low
Solution Approach 1:
The power supply system is segmented into multiple independent power supply systems (first power supply system and second power supply system), each capable of independently supplying power to the electric fracturing device. This segmentation allows one system to take over when another fails, improving reliability without requiring a single complex integrated system.
Solution Approach 2:
The patent changes the parameter of power supply configuration from a single system to multiple systems, transforming the operational parameters to enable flexible switching and redundant operation, thereby improving reliability while maintaining manageable system complexity through modular architecture.
2Productivity
If a power generator with large power is operated during idle intervals, then the maximum power demand can be satisfied, but energy consumption increases and electricity usage efficiency decreases
Solution Approach 1:
The power supply capacity is segmented into different tiers: a first power supply system with large power capacity for maximum demand during fracturing operations, and a second power supply system with smaller power capacity for idle intervals. This segmentation allows the system to match power consumption with appropriate power supply capacity, reducing energy waste during idle periods while maintaining the ability to satisfy maximum power demands when needed.
3Adaptability or versatility
If multiple power supply systems are adopted without unified control, then power supply flexibility improves, but operational difficulty and control complexity increase
Solution Approach 1:
The control system continuously monitors the operational status of both power supply systems and automatically adjusts power distribution based on real-time feedback. When one system fails or when power demand changes, the control system receives feedback and switches between systems accordingly, providing power supply flexibility while simplifying operation through automated control rather than manual intervention.
