Abstract: Fracturing is one of the main stimulation measures for developing the new field and stabilizing the production of matured field in low permeability J1lin oilfield. The effects of fracturing are influenced by a lot of factors. This paper, starting from the analyzing of the influential factors, points out that the man-made fractures should be treated in the proper time after fracturing, the substances damaging the fractures must be cleaned out, the flow conductivity of the fractures should be recovered. By doing so, the output of the oil well can be increased, and the effective period of fracturing can be prolonged.
