Abstract: As a new technique for tertiary oil recovery or EOR, artificial earthquake stimulation is increasingly valued for its quick response, high efficiency, non-pollution to well and influence-free on regular production of oilfield. Its principle is that the using vibroseis, the high frequency ray produced from seismic ray which acts on the strata may allow to produce cracks or fractures and to form some new channels for hydrocarbon migration, thus further improving the reservoir quality and physiochemical property of crude oil for the purpose of increasing production rate. This paper introduces the very obviously practical results using this stimulation to Karamay area for EOR performed by Xinjiang Oyasa Mineral Exploration Company Ltd. It is indicated that the artificial earthquake stimulation is worth popularizing in the future.

Key words: artificial earthquake, vibroseis, stimulation, resonance
