- •
The hydrothermal jet drilling technology with a multi-orifice nozzle is proposed by combining the advantages of thermal spallation and high pressure water jet methods.
- •
The characteristics of impact flow field are revealed and influences of key factors are analyzed.
- •
The heat transfer effect between wellbore fluid and ambient rock is investigated to obtain higher penetration rates for field-application.
