Drilling Power Supply System with Centralized and Distributed Units
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional exploration drilling systems require multiple independent power supply devices to meet different power intensity needs for well drilling and fracturing, leading to low utilization rates and high extraction costs due to the need for separate devices for each process.
Innovation Solution
A centralized power supply system coupled with distributed power supply systems to provide power to both drilling and fracturing operations, with the centralized system supplying stable high power for fracturing and additional power from distributed systems during peak loads for drilling, optimizing resource use and reducing the number of required devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple independent power supply devices are used to separately supply power to drilling and fracturing systems, then the power requirements of both processes can be satisfied, but the number of devices increases and utilization rate decreases
Solution Approach 1:
The patent implements a shared power supply system where a single power supply device can serve both drilling and fracturing operations. The power supply system is designed with modular components that can be dynamically allocated to different drive systems based on real-time power demands, enabling one device to perform multiple functions that previously required separate dedicated devices.
Solution Approach 2:
The patent combines previously separate power supply systems for drilling and fracturing into a unified shared power supply infrastructure. By merging the power supply functions and implementing a common electrical grid with intelligent load management, the system reduces the total number of power supply devices while maintaining the ability to meet the high power demands of both operations simultaneously or sequentially.
2Adaptability or versatility
If multiple independent power supply devices are used for drilling and fracturing, then different power intensities can be supplied, but the utilization rate of power supply devices is low and extraction costs are high
Solution Approach 1:
The patent implements a dynamic power allocation system that continuously monitors and adjusts power distribution based on real-time operational demands. The system can dynamically switch between drilling and fracturing loads, adjust power intensity levels, and optimize the utilization of available power supply capacity. This dynamic management ensures that power supply devices operate at optimal utilization rates while adapting to varying power intensity requirements of different operations.
Solution Approach 2:
The shared power supply system is designed to maintain continuous useful action by seamlessly transitioning between different operational modes and loads. Rather than having idle periods where power supply devices are underutilized, the system continuously optimizes power distribution to match actual demand, ensuring high utilization rates while maintaining the flexibility to adapt to different power intensity requirements for drilling and fracturing operations.
3Power
If separate power supply devices are used for drilling and fracturing, then specific power needs can be met, but the purchase cost increases due to needing more devices
Solution Approach 1:
The patent designs power supply devices with universal capabilities that can deliver the specific power levels required for both drilling and fracturing operations. By creating multi-functional power supply units that can be dynamically configured and allocated, the system maintains the necessary power delivery capability for each operation while reducing the total quantity of power supply devices needed compared to having separate dedicated devices for each function.
