摘　　要：大港油田已进入开发中后期,高含水油田占73％,开发初期的一些参数已不适合现在开 发的需要。研究出一套用试井方法确定注水以后地层渗透率变化的方法,对大港油田的增储上产 具有重要意义。Dagang oilfield is already at middle or past development period, of which high containing water oilfields 73%, some parameters are not suit for developing need. A set of methods determining change of formation permeability after injection water by testing way have an important benefit for increasing production potential of Dagang oilfield.
