Amelioration of petrophysical property with shock waves generated by underwater electrical wire explosion

Underwater electrical wire explosion will convert electrical energy into mechanical energy and generate strong shock wave has been well applied in underwater plasma sound source, electrohydraulic manufacturing, rock breaking, oil production improvement and many other fields. This way has the advantages of controllable energy, tunable frequency, equipment compactness and is convenient and cost-effective in industrial applications. Some coal-bed gas and shale gas and oil wells have encountered the reduction problem, and some may stop produce because of the poor reservoir lithology. This paper examines a novel method to improve the low permeability of reservoir. The shock wave method gives an effective alternative for traditional methods, such as hydraulic fracturing, deflagration fracturing and so on.
