Fracturing Manifold Trailer Layout for Simplified Power Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional fracturing units in oil and gas fields face issues with complex electricity distribution, large space occupation, and hindrances in moving trailers due to the need for numerous cables and complicated connections, especially when using electrically-driven fracturing units.
Innovation Solution
A high and low pressure manifold liquid supply system that integrates a trailer with a platform, a high and low pressure manifold, a support frame, and a distribution switch cabinet to simplify electricity distribution, reducing the number of cables needed and facilitating the connection of electrically-driven fracturing units by locating all necessary interfaces at the rear portions of the trailers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If electric motors replace diesel engines with direct drive, then power efficiency and environmental performance are improved, but electricity distribution complexity and cable requirements increase
Solution Approach 1:
The patent combines the generator set and distribution switch cabinet into a single integrated power supply unit. The generator set directly drives the distribution switch cabinet, merging power generation and distribution functions into one compact system that eliminates complex cable networks while maintaining efficient power delivery to multiple fracturing units
2Reliability
If multiple separate cable connections are made to each fracturing unit, then reliable power supply is ensured, but well site space occupation and connection time increase
Solution Approach 1:
The distribution switch cabinet is pre-configured with multiple output circuits that can simultaneously supply power to multiple fracturing units. This preliminary setup eliminates the need for sequential cable connections, allowing all units to be powered simultaneously and significantly reducing total connection time while maintaining reliable power delivery
3Ease of manufacture
If electrical interfaces are placed at head portions and fluid interfaces at rear portions, then functional separation is achieved, but trailer movement is hindered
Solution Approach 1:
The fracturing trailer is designed with universal connection capabilities at both head and rear portions, allowing the same type of connections (both electrical and fluid) to be made at either end. This multi-functional design enables flexible trailer positioning and movement while maintaining all necessary connection functions, eliminating the constraint of fixed interface locations
