Solution Overview

Problem

Current coring tools face inefficiencies in cutting core samples due to the lack of real-time feedback and adjustment based on formation properties, leading to increased power usage and longer operation times, especially when dealing with varying rock types and consolidation levels.

Innovation Solution

A coring tool equipped with sensors for bit rotating speed, torque, weight on bit, and rate of penetration, which transmit data to the surface and are processed by a downhole controller to automatically adjust the coring parameters, such as rotating speed and weight, to optimize core extraction based on formation characteristics.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional coring tools operate with fixed parameters, then the device structure remains simple, but power consumption increases and operation time extends when dealing with varying rock types

Engineering Contradiction:
Improvecoring operation efficiencyVSAvoidpower consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The coring tool dynamically adjusts its operating parameters (rotational speed, weight on bit, feed rate) in real-time based on formation characteristics detected by sensors. The controller modifies these parameters automatically as the tool encounters different rock types and consolidation levels, optimizing cutting efficiency while minimizing power consumption for each specific formation condition.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system incorporates sensors that continuously monitor formation properties during coring operations and feed this information back to the controller. The controller processes this feedback and automatically adjusts coring parameters to maintain optimal efficiency, resolving the contradiction between productivity and power consumption by adapting to actual downhole conditions.

Inventive Principle:
Principle #23Feedback

If coring tools use automated adjustment based on real-time feedback, then productivity and core quality improve, but device complexity increases

Engineering Contradiction:
Improvecoring operation efficiencyVSAvoiddevice complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The controller serves multiple functions: it processes sensor data, determines formation characteristics, adjusts coring parameters, and optimizes cutting performance. By making the controller multi-functional, the patent reduces the need for separate dedicated components for each function, thereby managing device complexity while achieving automated real-time optimization of coring operations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The coring tool automatically monitors its own performance and the formation conditions through integrated sensors, and self-adjusts its operating parameters without external intervention. This self-service capability eliminates the need for complex external control systems and manual operations, improving productivity while keeping the overall system architecture manageable.

Inventive Principle:
