Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current drilling operations rely heavily on human intervention and experience, which can lead to inefficiencies and inconsistencies in adhering to best practices, particularly in managing various hole conditions and drilling challenges on a drilling rig.
Innovation Solution
An automated control system is implemented on the drilling rig, comprising a computer system, sensor engine, and operational equipment engine, which identifies and enforces operational guidelines with specific control limits for different hole sections, allowing for automatic adjustments to operational parameters to maintain optimal drilling conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If automated control system is implemented, then productivity and reliability are improved, but device complexity increases
Solution Approach 1:
The control system is segmented into distinct functional modules: a sensor engine for detecting operational parameters, a computer system for processing data and determining compliance, and an operational equipment engine for executing adjustments. This modular architecture improves productivity while managing complexity through organized functional separation.
Solution Approach 2:
The system pre-establishes control limits for operational parameters before drilling operations begin. These limits are determined based on hole section type and drilling conditions, allowing the automated system to immediately enforce best practices without requiring real-time human analysis, thereby improving productivity.
2Manufacturing precision
If automated control system is implemented, then manufacturing precision is improved, but device complexity increases
Solution Approach 1:
The sensor engine continuously monitors operational parameters and provides real-time feedback to the computer system. The computer system compares current parameter values against pre-established control limits and automatically triggers adjustments when deviations are detected, ensuring precise adherence to operational guidelines through closed-loop control.
Solution Approach 2:
The operational equipment engine automatically adjusts drilling parameters when deviations from control limits are detected, without requiring human intervention. The system serves itself by autonomously identifying non-compliance conditions and executing corrective actions, thereby maintaining manufacturing precision while the complexity is managed through automation.
3Loss of time
If real-time monitoring and automatic adjustment are implemented, then loss of time is reduced, but device complexity increases
Solution Approach 1:
The sensor engine operates continuously throughout drilling operations, providing uninterrupted monitoring of operational parameters. The computer system and operational equipment engine maintain continuous readiness to detect deviations and execute adjustments, ensuring that drilling operations proceed without unnecessary interruptions or downtime.
