Drilling Research on the Electrical Detonation and Subsequent Cavitation in a Liquid Technique (Spark Drilling). Status Report.

摘要

The results of all analytical and experimental studies completed to date indicate that the spark drilling system is feasible and promises rapid drilling rates. No areas have been found in which the physics of the spark drilling process indicates that the system will not work. Although much scientific and engineering development remains to be completed,the final success of this program appears favorable. With the recent success in longer life bit design,near term efforts will concentrate on design and fabrication of a high energy pulse generator,characterizing the breakdown phenomena in drilling mud,continuing the study of bubble action under high pressure,and optimizing the pulse generator for maximum rock breakage with minimum energy expended.
