Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fracturing well sites using fuel oil as power fuel face environmental and noise pollution issues, and the reliance on gas or oil-powered electric generators reduces efficiency and increases the risk of well site paralysis if power generation fails.
Innovation Solution
A fracturing and power generation switchable apparatus that includes a power device, speed transmission device, and bearing base, allowing the apparatus to switch between fracturing and power generation modes, reducing the number of well site apparatuses and saving space, with a control method to manage the switching based on displacement and power demands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fuel oil is used as power fuel in conventional fracturing well sites, then power supply is ensured, but environmental pollution and noise pollution are serious
Solution Approach 1:
The patent applies multi-functionality by enabling the well site apparatus to switch between two distinct operational modes: fracturing mode (using fuel oil to drive plunger pumps for hydraulic fracturing) and power generation mode (using the same fuel oil to drive electric generators for power supply). This dual-function design allows the system to address both fracturing operations and power supply needs while reducing environmental impact by replacing dedicated fuel-powered generators with switchable apparatus that can operate in cleaner fracturing mode when applicable.
2Adaptability or versatility
If multiple turbine fracturing apparatuses are arranged with both gas turbine engines and fuel oil engines, then power supply and fracturing capability are provided, but the layout is complex and inconvenient for environmental protection and control
Solution Approach 1:
The patent implements universality by designing a single apparatus that can perform both fracturing operations and power generation functions. The apparatus includes a power device (fuel oil engine or gas turbine), a speed transmission device, and a bearing base that can accommodate either plunger pumps or electric generators. This eliminates the need for separate dedicated engines for each function, simplifying the well site layout and control systems while maintaining full operational versatility.
Solution Approach 2:
The patent merges previously separate functions (fracturing and power generation) into a single integrated apparatus. By combining the power device, speed transmission device, and interchangeable working components (plunger pumps or electric generators) on a common bearing base, the system reduces the number of independent units required at the well site, thereby simplifying layout, installation, and control while improving environmental compliance.
3Productivity
If conventional fracturing apparatuses use dedicated fuel oil engines, then fracturing operations are maintained, but space is wasted and operational flexibility is reduced
Solution Approach 1:
The patent applies universality by designing an apparatus that can serve dual purposes: performing fracturing operations when plunger pumps are installed on the bearing base, and providing power generation when electric generators are installed instead. This eliminates the need for dedicated fuel oil engines that only perform fracturing, optimizing space utilization at the well site while maintaining full fracturing operational capability when needed.
