Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing oilfield injection systems for tertiary oil recovery and intelligent energy-gathered oil-displacing are cumbersome, occupying large areas, consuming high power, and requiring extensive time and resources, making them unsuitable for offshore platforms with limited space.
Innovation Solution
An integrated composite overload injection system is developed, featuring a feeding mechanism, composite overload mechanism, booster pump, and mixer on a rack, which reduces the occupied area and time for preparing the intelligent energy-gathered oil-displacing agent, and improves injection efficiency through a multi-functional composite overload mechanism and low-speed screw pump.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If traditional separate processes for dispersing, dissolving and ripening are used, then the preparation is thorough, but the occupied area and space are large
Solution Approach 1:
The patent combines the dispersing mechanism, dissolving mechanism, and ripening mechanism into a single integrated composite overload injection system. The composite overload mechanism integrates multiple functions (dispersing, dissolving, ripening) that were previously performed by separate devices, thereby reducing the occupied area and space while maintaining the thoroughness of preparation.
Solution Approach 2:
The composite overload mechanism is designed to perform multiple functions simultaneously - it can disperse, dissolve, and ripen the intelligent energy-gathered oil-displacing agent in one unit. This multi-functionality eliminates the need for multiple separate devices, reducing the overall occupied area while preserving the quality of preparation.
2Loss of time
If traditional dispersing and ripening tanks are used, then the preparation is complete, but the ripening time is long
Solution Approach 1:
The patent applies preliminary action by performing dispersing and dissolving operations before the ripening process in the composite overload mechanism. The dispersing mechanism breaks down aggregates first, then the dissolving mechanism ensures complete dissolution, which prepares the material in advance for faster and more effective ripening, thereby reducing the overall preparation time and improving productivity.
3Ease of repair
If plunger pump with solid-phase particles is used, then the injection is effective, but the maintenance period is short
Solution Approach 1:
The patent replaces the traditional plunger pump with a composite overload mechanism that uses a different mechanical approach - specifically, a screw conveyor system that gently transports the prepared agent without the high-impact mechanical action of a plunger pump. This substitution reduces wear and tear on components while maintaining effective injection, thereby extending the maintenance period without compromising injection effectiveness.
