The rational classification of reservoir is the basis of the reservoir comprehensive evaluation.So far,many parameters and methods of reservoir classification are put forward by some experts and scholars,but it has been very difficult to determine that which parameter and method can be used.A research has been carried out with Ed1 member of Miao 28X1 block in Laoyemiao oilfield in Jidong.Based on the key study and rational choice of classification parameters,the mathematical methods of Qmodel gathering and discriminant function are used tentatively in quantitative reservoir classification and evaluation of interval of interest in the study area.And the vertical and planar distribution characteristics of reservoir are also studied.The results show that the application of these methods to reservoir classification and evaluation is practical and present considerable comprehensiveness and scientific character.
