Hydraulic Fracturing Manifold Equalizer for Automated Pressure Bleeding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In oil and gas hydraulic fracturing operations, the hydraulic fracturing manifold often requires pressure bleeding, but existing methods, such as manually cracking a plug valve, result in valve discarding due to lack of greasing, leading to inefficiencies and equipment waste.
Innovation Solution
A hydraulic fracturing system incorporating an equalizer with automated pressure bleeding capabilities, actuated by a grease system and actuation system, which communicates lubricating grease to valves and frac legs, allowing for precise pressure control and reducing equipment disposal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual pressure bleeding is performed by cracking a plug valve, then pressure can be bled from the manifold, but the valve must be discarded due to lack of greasing
Solution Approach 1:
The system applies grease to the valve stem before opening the plug valve for pressure bleeding. This preliminary lubrication action prevents damage to the valve disc during the bleeding operation, allowing the valve to be reused instead of discarded.
2Duration of action of stationary object
If automated equalizer system with grease communication is implemented, then valve lifespan is extended through proper greasing, but system complexity increases
Solution Approach 1:
The equalizer system includes an automated grease communication mechanism that self-services the valve stem by delivering lubrication automatically during the pressure bleeding operation, eliminating the need for manual greasing while extending valve lifespan.
Solution Approach 2:
The equalizer system performs multiple functions: it controls pressure bleeding, communicates grease to the valve stem, and manages the overall bleeding process through a single integrated mechanism, reducing the need for separate components.
