Recombination of Layer Series of Development in High Water-Cut Oil Field
Bao Jing-wei · Xinjiang shiyou dizhi · 2010
Recombination of layer series of development is an important part in redevelopment project of a high water-cut oil field.For quantification of it from qualitative analysis,the fuzzy cluster-F statistics and independence test of layers (FFT) method suitable for such an oil field is presented.A series of preliminary and better classification are obtained by consideration of affecting factors on reservoir geology and exploitation,and the recombination scheme for this field is proposed in terms of the independent test and selection of layers.The FFT method is used in redevelopment project of Block 2 in western Dagang oil field and three layers of development of N2m I+N2m II+ N2m Ⅲ,N1g I+ N1g II and N1g Ⅲ are given.
