Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If sensors are placed downhole close to the flow of fluids to monitor treatment and production operations, then real-time monitoring capability is improved, but the space between the outer string and the casing is encroached upon

Engineering Contradiction:
Improvereal-time monitoring capabilityVSAvoidspace between outer string and casing
Core Design Contradiction:
Measurement precisionVSVolume of moving object

Solution Approach 1:

The sensor assembly is nested within the inner string, which itself is contained within the outer string. This nested configuration allows sensors to be positioned close to the fluid flow for effective monitoring while maintaining the structural integrity and space requirements of the outer assembly and casing annulus.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The completion assembly is divided into distinct segments: an outer assembly containing packers and flow control devices, and an inner assembly containing the sensor and additional flow control devices. This segmentation allows the sensor to be isolated in the inner string without interfering with the outer string's function or encroaching on the casing annulus space.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If wireless signal transmission is used to convey sensor data to the surface, then real-time data communication is improved, but device complexity increases

Engineering Contradiction:
Improvereal-time data communicationVSAvoidwireless signal transmission system
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent replaces complex wired data transmission systems with wireless signal transmission. This substitution eliminates the need for physical connections between the downhole sensor and surface equipment, simplifying the overall system architecture while enabling real-time data communication through electromagnetic waves.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
