| Abstract: | Some fractures are produced near wellbore zone by multi pulse high energy gas fracturing, and they link up with natural fractures. At the same time as fracturing or after fracturing, ClO 2 treatment liquid is squeezed into formation to remove the organic matter, inorganic matter and bacteria in oil reservoir, so the permeability of the oil reservoir is improved. This treatment technology of oil reservoir gives full play of both high energy gas fracturing and ClO 2 treatment. It was applied to 5 wells in Shanbei oilfield in 2000, and the results show that this technology can effectively remove the pollution of fracturing fluid, dirt and bacteria to oil reservoir near wellbore zone. |
