Solution Overview
Problem
Current methods for inspecting the operating state of high-pressure manifolds in the oil and gas fracturing industry are ineffective due to high costs and poor accuracy, particularly with manual recording and sensor-based solutions, which often fail to timely identify manifold failures leading to accidents.
Innovation Solution
A method involving the creation of a connection diagram of high-pressure manifolds using device nodes, with data collection from start to end nodes to determine the operating state, including flow parameters, health state, and remaining life, utilizing RFID tags and computational formulas to assess cumulative service time, flow rate, pressure, and sand quantity scores.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual recording and inspection methods are used for high-pressure manifolds, then inspection cost is low, but inspection accuracy and timeliness are poor leading to safety accidents
Solution Approach 1:
The patent introduces an intermediary system consisting of a manifold management system, connection diagram generation module, and data processing center that mediates between the physical manifolds and inspection personnel. This intermediary automatically collects manifold data, generates connection diagrams, and provides inspection recommendations, thereby improving inspection accuracy without requiring complex manual intervention while keeping the overall system relatively simple
Solution Approach 2:
The patent creates a virtual copy of the manifold system through connection diagrams that represent the physical manifold network. This digital copy allows for automated data collection, analysis, and inspection planning without directly complicating the physical manifold structure, thus improving measurement precision while maintaining device simplicity
2Reliability
If sensors are added to all manifolds for data collection, then inspection accuracy improves, but implementation cost and complexity become tremendous
Solution Approach 1:
The patent creates a universal manifold management system that can handle multiple types of manifolds (common high-pressure manifolds, confluence skids, diversion skids) through a single integrated platform. The system uses standardized data collection methods and connection diagram representations that work across different manifold types, improving reliability without requiring specialized sensor installations for each specific manifold type
Solution Approach 2:
The manifold management system acts as an intermediary that collects and processes manifold data without requiring direct sensor integration into every manifold component. The system manages the complexity of data collection and analysis centrally, thereby improving reliability while avoiding the tremendous complexity of mounting and managing sensors on all manifolds individually
3Ease of manufacture
If sensors are mainly added on large manifolds, then cost is reduced, but accidents often occur on small manifolds showing this solution produces little effect on preventing system breakdown
Solution Approach 1:
The patent segments the manifold inspection system into hierarchical levels, with the manifold management system providing overarching monitoring and connection diagram generation, while allowing for focused data collection on specific manifold segments (including small manifolds) based on risk assessment and operational importance. This segmentation enables cost-effective implementation that doesn't require sensors on every single manifold while still maintaining system-wide safety through the centralized management system
Solution Approach 2:
The patent applies local quality by enabling the manifold management system to provide differentiated inspection and monitoring levels for different manifold locations and types. The system can prioritize data collection and inspection resources for small manifolds that are prone to failures while maintaining overall system reliability, thereby achieving both cost effectiveness and comprehensive safety coverage
