Abstract: Production by artificial earthquake is a new tertiary oil recovery technology because of high technology, less input, high output and simple technology. It pays attention to no pollute to oil layers and environment. By studying on artificial earthquake, the paper introduced theory of artificial earthquake and effect factors. Through experiment, the paper also pointed the adaptable condition and ranges of artificial earthquake. The examination of the technology in Pucheng Oilfield gets good result and daily oil production increased by 3t, and gas increased by 8000m³. The technology is helpful to improve oil recovery in Pucheng Oilfield.
