Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a continuous mixing truck is used, then continuous mixing capability is achieved, but operational cost increases and pipeline connection becomes complex
Solution Approach 1:
The system is divided into separate functional modules: a drag reducer concentrate storage tank, a water storage tank, a mixing device, and a sand mixing device. Each module can be independently configured and connected, simplifying the overall pipeline connection complexity while maintaining continuous mixing capability through modular design
Solution Approach 2:
A pneumatic delivery system acts as an intermediary between the drag reducer concentrate storage tank and the mixing device, enabling automatic and continuous delivery of drag reducer concentrate without complex manual intervention or intricate pipeline configurations
2Ease of operation
If drag reducer concentrate is formulated before hydraulic fracturing operations, then on-site operation requirements are not met, but pre-formulation workload increases and dissolution performance deteriorates
Solution Approach 1:
The system performs preliminary concentration formulation in a controlled environment before on-site use, creating a stable drag reducer concentrate that can be stored and then continuously mixed with water and sand at the job site. This separates the formulation process from the application process, maintaining both dissolution performance and on-site flexibility
Solution Approach 2:
The system transitions from static pre-formulated concentrate to a dynamic continuous mixing process at the job site. The mixing device continuously combines drag reducer concentrate with water and sand, adjusting the mixture in real-time to meet on-site operational requirements while maintaining consistent dissolution performance
3Productivity
If traditional fluid formulation methods are used, then simple equipment is required, but continuous mixing capability is not achieved
Solution Approach 1:
The mixing device operates continuously to maintain consistent drag reducer concentration in the fracturing fluid. The pneumatic delivery system continuously supplies drag reducer concentrate from the storage tank to the mixing device, ensuring uninterrupted mixing action throughout the hydraulic fracturing operation
Solution Approach 2:
The system incorporates automatic control mechanisms where the pneumatic delivery system automatically regulates drag reducer concentrate flow based on operational requirements, and the mixing device self-regulates the mixing process. This reduces the need for complex manual intervention while maintaining continuous mixing capability
