Shale Oil Guar Gum System Enzyme Breaker

• 

This enzyme product is developed based on synthetic biology technology with AI-assisted structural redesign. By optimizing mannosidase/mannanase genes derived from extremophilic microorganisms and utilizing expression systems such asE. coli, yeast, andBacillus subtilis, it achieves high-density and high-efficiency production of enzyme protein. It features high specificity, continuously hydrolyzing β-1,4 glycosidic bonds in guar gum and its modified products, achieving thorough breaking and effectively removing formation damage caused by fracturing fluid residues and filter cake. This product is a high-temperature biological enzyme breaker specifically developed for guar gum fracturing systems in shale oil wells and high-temperature reservoirs. It maintains high activity under high-temperature and high-pressure conditions, enabling fast and complete breaking.

Product Advantages and Application Scenarios:

1. Maintains high activity under the high-temperature environment of shale oil reservoirs, overcoming the temperature limitations of traditional breakers, achieving fast and thorough breaking.
2. Specifically hydrolyzes β-1,4 glycosidic bonds of guar gum, significantly reduces residue content, and protects reservoir flow channels.
3. Biological enzyme method replaces oxidative breaking, non-corrosive, no harmful residues, meeting stringent environmental requirements.
4. Salt-tolerant and shear-resistant, adapts to complex fracturing fluid systems, maintains stable performance during long-duration operations.
5. Enhances fracture conductivity, increases flowback rate, and helps unlock shale oil well productivity.
