Parameter Selection by Artificial Earthquake Stimulation Method

Abstract

Abstract: Artificial earthquake stimulation is one of EOR methods. Using this method may allow reservoir fluid viscosity to be decreased, oil layer permeability to be increased, residual oil saturation to be lowered, thus the oil production to be rise. It is showed that only the vibration operation parameters that fit with the geologic feature in operation district are selected, can the best stimulation efficiency be obtained. The method for parameter selection of artificial earthquake stimulation is presented in this paper. And the applied effects to Karamay oilfield are obviously good.

Key words: artificial earthquake, vibration frequency, vibration time, vibration interval, stimulation
