Modular Electric Pumping Unit for Fast Pump Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pumping units, such as those used for wellbore operations, are not modularized, leading to time-consuming pump replacements and transportation challenges due to their weight and non-modular design.
Innovation Solution
A modularized electric pumping unit with removable pump modules, comprising a base structure and detachable pump modules that include a pump, driveline, and auxiliary systems, allowing for efficient assembly and disassembly for transportation and maintenance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional non-modular pumping units are used, then complete pumping units must be maintained as back-ups, but replacing a pump becomes time-consuming and transportation becomes challenging due to weight restrictions
Solution Approach 1:
The pumping unit is divided into a base structure and detachable pump modules. The pump module can be independently removed and replaced without replacing the entire pumping unit, enabling faster pump replacement while maintaining a simpler backup system configuration.
2Ease of operation
If conventional non-modular pumping units are used, then complete pumping units must be transported as single units, but transportation becomes difficult due to weight restrictions
Solution Approach 1:
The pumping unit is segmented into a base structure and removable pump modules. Only the necessary components are transported to the well site, and the pump module can be detached for transportation, significantly reducing the weight and complexity of logistics compared to moving complete pumping units.
Solution Approach 2:
The pump module is extracted as a separate, independently transportable component from the base structure. This allows the pump to be transported separately and attached at the destination, avoiding the need to transport the entire pumping unit assembly.
3Ease of repair
If conventional non-modular pumping units are used, then pump replacement requires complete unit replacement, but this increases maintenance time and capital requirements
Solution Approach 1:
The pumping unit is divided into a base structure and detachable pump modules, allowing the pump module to be independently removed and replaced. This modular design enables rapid pump replacement without requiring complete unit replacement, significantly reducing maintenance time and simplifying repair operations.
