Application of Re-fracturing Technology in Low-permeability Oilfield of Jianghan

Part of the research on oil well re-fracturing was carried out in Jianghan Oilfield and as well as the recognition of re-fracturing mechanism in the oilfield were introduced.

stress field induced by existed fractures and oil production in SN Oilfield is simulated in this paper, it is proven that the azimuth of new fractures created by re-fracturing will be different from that of existed fractures on the base of principle of minimum principal stress.
