Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional drilling technologies struggle to effectively gather and process downhole sensor data in a timely manner, leading to drilling errors that increase costs and reduce well output, particularly in complex directional drilling scenarios.
Innovation Solution
A drilling system incorporating a steering control system that processes data from downhole sensors, provides real-time feedback, and enables manual, semi-automatic, or automatic control of drilling operations to optimize well trajectory and reduce errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional drilling technologies are used, then drilling operations can be performed, but drilling errors occur that increase costs and reduce well output
Solution Approach 1:
The system incorporates real-time feedback loops where downhole sensor data is continuously transmitted to surface control systems, processed, and used to adjust drilling parameters dynamically. This closed-loop control enables correction of trajectory deviations before they become errors, improving both drilling accuracy and preventing productivity loss from mistakes
Solution Approach 2:
The patent replaces manual mechanical drilling control with automated electronic control systems. Computer algorithms process sensor data and automatically adjust drilling parameters, substituting human operator mechanical control with precision electronic actuation systems that reduce errors and improve reliability
2Measurement precision
If real-time data processing is implemented, then drilling accuracy improves, but system complexity increases
Solution Approach 1:
The data processing system is segmented into modular functional units: sensor data acquisition modules, telemetry transmission modules, calculation algorithms for trajectory determination, and control output modules. Each segment handles specific processing tasks independently, improving measurement precision while managing system complexity through functional decomposition
Solution Approach 2:
The control system integrates multiple functions into unified processing units that simultaneously handle trajectory calculation, sensor data fusion, and control parameter generation. This multi-functionality reduces the number of separate components needed, achieving high measurement precision without proportionally increasing device complexity

AI summary
Downhole display systems and methods. A display of one or more portions of a well log of a well during drilling may be displayed together with a display of one or more portions of one or more reference well logs, which may be presented as projected onto one or more planes, respectively. The logs may be segmented and correlated, with the segments or correlated portions displayed in different colors. A user may manipulate the display of the logs or log segments to assist in correlating them. The user may also manipulate the display so that the view provided of the wellbore and the projected logs changes in any one or all of three dimensions. In addition, the user may manipulate the display by navigating along the length of the borehole to view the projected logs at any point along the well path.
