ENHANCED OIL RECOVERY
HYDRAULIC CAVITATION OIL PRODUCTION TECHNIQUE
Mechanism
• Cavitation is the formation of vapour cavities in a liquid, small liquid-free zones ("bubbles" or "voids"), that are the consequence of forces acting upon the liquid. It usually occurs when a liquid is subjected to rapid changes of pressure that cause the formation of cavities in the liquid where the pressure is relatively low.
• When subjected to higher pressure, the voids implode and can generate an intense shock wave.
Working principle
The hydraulic cavitation transducer is a power source to generate a cavitation shock wave field. The shock wave will passed by through the liquid in reservoir to cause multi-stage cavitation, as a result, the pores and micro-fractures will be connected to improve the reservoir.
