Rotary Steerable Tool Testing Bench for Horizontal Drilling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of a mature apparatus for testing the function and performance of push-the-bit rotary steerable tools in a horizontal or inclined state, as existing testing apparatuses are limited to vertical or fully-rotary configurations, failing to simulate horizontal or directional drilling states effectively.
Innovation Solution
An apparatus comprising a rotary steerable tool testing bench that simulates horizontal or inclined states, equipped with a testing assembly for high-precision measurement of pushing force and real-time force signal feedback, and a low-speed rotation driving control assembly to test the performance of push-the-bit rotary steerable tools, including a servo motor, worm and gear reducer, and toothed pulley system for accurate speed control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing testing apparatuses are used for vertical or fully-rotary configurations, then testing can be performed in those specific states, but the apparatus cannot simulate horizontal or directional drilling states
Solution Approach 1:
The testing apparatus employs a movable testing bench that can be adjusted between vertical and horizontal positions, allowing the system to dynamically adapt to different drilling states. This dynamic positioning capability enables testing of rotary steerable tools in both vertical and horizontal/inclined states without requiring multiple fixed apparatuses.
Solution Approach 2:
The testing apparatus is designed with universal functionality to test both push-the-bit and fully-rotary steerable tools in multiple drilling states (vertical, horizontal, and inclined). The system integrates multiple testing capabilities including pushing force measurement, rotation speed control, and directional drilling simulation into a single multi-functional platform.
2Reliability
If push-the-bit steerable tools are tested in horizontal or inclined states, then realistic drilling performance can be evaluated, but existing apparatuses lack the capability to simulate these states
Solution Approach 1:
The testing bench is designed with movable and adjustable components that can be positioned at various angles to simulate different drilling states. The bench can be tilted to create inclined states and positioned horizontally, enabling accurate simulation of real drilling conditions for reliable performance evaluation.
Solution Approach 2:
The testing apparatus introduces an intermediary testing bench structure that mediates between the tool being tested and the measurement systems. This bench serves as a platform that can be configured in different states (vertical, horizontal, inclined) to accurately represent actual drilling conditions while allowing instrumentation to measure tool performance.
3Measurement precision
If high-precision measurement of pushing force is implemented, then accurate performance data is obtained, but the measurement system becomes more complex
Solution Approach 1:
The measurement system extracts and isolates the pushing force measurement function using dedicated force sensors positioned at specific locations. By separating the measurement function from the structural components, the system achieves high measurement precision while maintaining clear functional boundaries that simplify overall system understanding.
Solution Approach 2:
The system implements real-time feedback of force measurement data through signal acquisition and processing systems. The force sensors continuously monitor pushing forces on the ribs, and the data is fed back to the control system for analysis, enabling accurate performance evaluation with automated monitoring and recording capabilities.
4Manufacturing precision
If low-speed rotation control is implemented for non-rotary steering sleeve testing, then precise force vector following can be tested, but the control system becomes more complex
Solution Approach 1:
The control system introduces an intermediary low-speed rotation driving assembly that mediates between the power source and the non-rotary steering sleeve. This intermediate mechanism provides precise speed control and torque management, enabling accurate testing of force vector following at low rotation speeds while isolating the complexity of control from the basic rotation function.
