Abstract

The Chang 8 reservoir in Zhenjing Oilfield in Ordos Basin is ultra-low permeability reservoir. There are various factors influencing the production with complex correlation, which brings a lot of difficulties in productivity prediction. The log response characteristics of oil layer, poor-oil layer, oil-water layer and dry layer are identified and the effective thickness of oil layer, poor-oil layer and oil-water layer are calculated. The main factors influencing the productivity are found out by testing data, by using which a correlation coefficient has good linear relation with productivity is build up, and then the productivity is predicted.
