hailaer oilfield belongs to low permeability fault-block oilfield, some blocks effectively injection Wells after fracturing is still hard, lead to low formation pressure, the late refracturing effect is poor, single and average increased under 400 t oil and to explore effective fracturing technology in the low permeability elastic exploration area, hailaer oilfield since 2011, in fissured budate reservoir, according to the characteristics of the reservoir Large-scale clear water fracture network fracturing tests have been carried out, and better stimulation effect has been achieved. The tests have guiding significance for the effective development of low efficiency and difficult to recover reservoirs in Hailaer oilfield.
