| Summary: | In recent years, the application of electrical explosion shockwave as a stimulation technology is increasing in oil fields, but lacks relevant theoretical knowledge to support it. In view of this problem, a research was carried out on experimental study of electrical explosion shockwave stimulation on the tight sand reservoir to determine the effective range of the resulting effects. An experimental platform for testing electrical explosion shockwave is established. Porosity, permeability and other mechanical parameters of tight sand stone samples are tested before and after electrical explosion shockwave treatment. The result shows clear improvement of the above mentioned parameters and the effective range. |
