  • The third member of the Shahejie Formation in Gaoshangpu oilfield is a set of fan delta deposition, which is characterized by bad physical properties and abundant clay mineral. As a result, its development effects were low. Reservoir sensitivity was studied in this paper through the core flow experiment. The results showed that the reservoir possessed strong velocity sensitivity, water sensitivity, alkali sensitivity and poor salt sensitivity. Reservoir sensitivity is a main factor to influence development effects. On the bases of rock composition and pore structure analysis, the formation mechanism of different sensitivity was analysed respectively, and the pertinent measures to control sensitivity in the course of development were brought out. The results of this paper is helpful to adjust reservoir development plans and made good effects in the experimental area .
