Solution Overview
Problem
The regeneration of drilling fluid is complex, resource-intensive, and energy-consuming, particularly when conducted in remote locations, requiring significant storage and transportation of additives like bentonite and water, and often involves energy generation through internal combustion engines, leading to environmental issues.
Innovation Solution
A method and device for regenerating drilling fluid that involves quality monitoring and selective tank storage, using vibrating screens and centrifuges for cleaning, and controlled energy use, allowing only high-quality fluid to be reused and poor quality to be treated, with on-site power generation and remote monitoring to optimize resource and energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If drilling fluid is regenerated using conventional methods with multiple tanks and additives, then the drilling fluid quality is improved, but the device complexity and storage requirements increase significantly
Solution Approach 1:
The system segments the drilling fluid processing into two distinct pathways based on quality assessment: a quick-exchange pathway for fluids meeting quality criteria and a regeneration pathway for those that don't. This segmentation allows the system to handle different fluid conditions differently, improving overall efficiency while maintaining quality standards.
Solution Approach 2:
The system incorporates automated quality sensors that continuously monitor drilling fluid parameters and automatically route fluid to appropriate processing pathways without manual intervention. The system serves itself by making real-time decisions about fluid handling based on measured quality parameters.
2Productivity
If drilling fluid is regenerated in remote locations, then drilling operations can continue uninterrupted, but the transportation and storage of additives like bentonite and water become more costly and complex
Solution Approach 1:
The system extracts only the necessary components for fluid quality restoration from the complex mixture of additives. Instead of transporting and storing large quantities of pre-mixed drilling fluid or multiple additive types, the system uses minimal additives (bentonite and water) that are strategically stored, and only introduces them when quality sensors detect degradation beyond threshold levels.
Solution Approach 2:
The system monitors key quality parameters (viscosity, density, gel strength) and adjusts additive dosage dynamically based on actual fluid condition. This parameter-based control allows the system to use minimal amounts of additives only when necessary, rather than continuously adding materials.
3Reliability
If conventional regeneration methods are used, then drilling fluid can be cleaned, but a significant amount of energy is required, often generated by internal combustion engines causing environmental issues
Solution Approach 1:
The system applies partial action by using vibration and air injection only when and where needed in the fluid pathway, rather than continuously treating the entire fluid volume. The vibratory screen activates only when solids content exceeds thresholds, and air injection is applied selectively to enhance separation efficiency only during high-contaminant conditions.
Solution Approach 2:
The system replaces energy-intensive thermal or chemical treatment methods with mechanical vibration and pneumatic injection. The vibratory screen uses mechanical oscillation to separate solids from fluid, and compressed air is used to fluidize and separate particles, both consuming significantly less energy than conventional heating or chemical treatment processes.
4Reliability
If all drilling fluid is regenerated regardless of quality, then consistent fluid quality is maintained, but resources and energy are wasted on fluids that already meet quality criteria
Solution Approach 1:
The system implements continuous feedback through quality sensors that monitor drilling fluid parameters in real-time. Based on this feedback, the system automatically adjusts its processing intensity and additive dosage. When sensors detect that fluid quality remains within acceptable ranges, the system reduces or suspends treatment activities, preventing energy waste while maintaining quality consistency.
Solution Approach 2:
The system dynamically adjusts its regeneration intensity based on real-time quality measurements rather than using a fixed, continuous processing regime. The vibration amplitude, air injection rate, and additive dosing are all dynamically controlled based on measured fluid parameters, allowing the system to optimize energy usage while maintaining quality standards.
