Abstract：It has been formed a set of effective reservoir-identified techniques to carry out reservoir appreciation by using logging data now, but it still has some difficulty to identify the fluid nature of fractured reservoir in complex lithology by using the set of techniques,for example,it is difficult to identify the reflection of electric property for fluid in stratum because of the influence of lithology and fracture.Especially,the response of logging data is complex in the reservoir of Qingxi oilfield, and it can't achieve good results by using logging data to identify the oil layer and water layer.For that reason, the paper used normal distribution to correctly judge the fluid property in corresponding reservoirs of Qingxi oilfield,better identified oil layer and water layer, which achieved better applied results in oilfield application.
