Cavitating and Structured Jets for Mechanical Bits to Increase Drilling Rate—Part I: Theory and Concepts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The erosion and cleaning effect of jets is enhanced when the degree of cavitation on or near the bottom of the hole is increased. Analyses indicate that self-excited, acoustically resonating ...
Cavitating and Structured Jets for Mechanical Bits to Increase Drilling Rate—Part II: Experimental Results
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Analyses of self-excited, resonating jets have been corroborated by laboratory experiments. These structured jets achieved cavitation at greater ambient pressures and showed enhanced erosivity in ...
