The grey interconnect analysis method is used in two aspects in this paper. One is to decide the main factor which have great effect on the production decline rate, the other is to select the main wells which have great effect on the main factor. On the first aspect, the affecting factors which are independent and have direct influence on the decline rate are normalized respectively. Then the interconnect sequence of the affecting factors are obtained by using the grey interconnect analysis method. On the second aspect, the water cut is taken as the reference sequence, the water production rate of every wells is taken as the factors sequence, then the main wells which have great effect on the water cut are selected by using the Grey interconnect analysis method. The results shows that the grey interconnect analysis method can adapt to the features of the more influence factors and the larger date size, and can be used in the analysis and trace for affecting factos of production decline.
