In order to explore an effective way to further increase the single well production and improve the development effect of low permeability fractured oilfield, it provides a new theoretical and practical basis for oilfield development in Taizhao area; Through the study of advanced water injection mechanism and field test in source A well area, an effective displacement pressure system is established in low permeability reservoir, which reduces formation damage caused by formation pressure drop and initial water cut of oil well, and optimizes the scheme by combining modeling and numerical prediction, water injection development adjustment and so on; Therefore, the output of the oilfield at the initial stage of production is increased; Good development results have been achieved in the early stage of production after 6 months’ advanced water injection in source A well area, and it is advisable to carry out advanced water injection for 6 months in the development of low permeability fractured oilfield.
