The Application of In-Fissure Divert Fracturing Technology in Ultra-Low Permeability Oilfield

According to the geologic characteristic and development,<br>performance of ultra-low permeability reservoirs ，and<br>oil-water distribution rules of reservoir, this paper puts<br>forward the key points in improving the single well<br>production of old oilfield—develop the “dead oil area”,<br>and forms supporting technologies of in-fissure divert<br>fracturing which is suitable for ultra-low permeability<br>reservoirs. The onsite experiments prove that the infissure<br>divert fracturing technology can effectively<br>improve old well production of ultra-low permeability<br>reservoirs.
