Oil shale is an unconventional energy source, and it also a potential petroleum substitute. Nowadays, the shortage becoming more prominent, oil has attracted attention of researchers all over world. Borehole hydraulic mining effective method to exploit underground which prominent advantages than other conventional methods. Jet devices are key component borehole mining, include straight cone nozzle, organ pipe nozzle self-excited oscillation pulsed jet nozzle. Also, reasonable parameters crucial in efficiency. The characteristics non-submerged water jet, submerged direct cavitating explained compared based on theoretical analysis. performance better jet. Each type its own basic principles optimal structural parameters. best operating scheme for use produced by break under condition. Moreover, should be placed parallel bedding. In addition, preconditions ensuring safety reliability equipment pipelines connection, pressure flow raised as much possible, so obtain higher These results conclusions can provide very valuable guidance shale.
