RESEARCH AND APPLICATION OF RESERVOIR TREATING TECHNOLOGY BY PULSE DISCHARGE OF HIGH VOLTAGE CURRENT

This paper introduces the principle of reservoir treating technology by pulse discharge of high voltage current:the energy accumulated in the large capacity high voltage accumulator is released, and thus produces strong pulse wave with wider frequency band;the pulse wave influences the near wellbore formation, forms cavitation, removes the plugging materials in the pores and throats, results in microfractures, and thus improves the permeability of near wellbore format1on. This paper also introduces the field application of this technology, which indicates that the technology can effectively remove the near wellbore formation contamination and attain the goal of stimulating injectors and producers. The technology 1s also characterized by low investment, rapid effectiveness, simple construction and high benefit.
