Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional wireline surface equipment (winch, cable, pulley system) is used to convey tool strings, then reliable conveyance is achieved, but deployment time and equipment complexity increase
Solution Approach 1:
The patent extracts and eliminates the wireline surface equipment (winch, cable, pulley system) from the conveyance process. Instead, it uses the drilling rig's existing mud pump and drill pipe to convey the apparatus, thereby removing the time-consuming setup and deployment of separate wireline equipment while maintaining conveyance functionality through the drill pipe medium
Solution Approach 2:
The patent makes the drilling rig's mud pump system multi-functional by using it not only for drilling operations but also for conveying the apparatus and tool strings into the wellbore. This eliminates the need for dedicated wireline conveyance equipment and reduces overall equipment complexity and deployment time
2Reliability
If multiple pieces of surface equipment are used for conveyance, then conveyance capability is ensured, but device complexity increases
Solution Approach 1:
The patent merges the conveyance function with the existing drilling rig system by integrating the apparatus into the drill pipe and using the mud pump for conveyance. This combines multiple functions (drilling fluid circulation and tool string conveyance) into a single unified system, eliminating the need for separate wireline equipment and reducing overall device complexity
Solution Approach 2:
The drilling rig's mud pump and drill pipe are made multi-functional to perform both drilling operations and apparatus conveyance, thereby eliminating dedicated wireline equipment and reducing the total number of components required in the system
3Loss of information
If mud pulser is added for selective outlet control, then data transmission capability is improved, but apparatus complexity increases
Solution Approach 1:
The mud pulser is designed to serve multiple functions: it controls the mud outlet for pressure management during conveyance and simultaneously enables data transmission to the surface by modulating the mud flow. This dual functionality allows data communication without requiring separate dedicated telemetry equipment, offsetting the added complexity with functional consolidation
