Abstract
The development of metamorphic buried hill fractured reservoirs is poor in Hailar oilfield,so,it is difficult to evaluate reservoir effectiveness.In the oilfield development process,a large number of low yield wells appear.In order to further explore the potential of oil layers and increase the production of oil wells,we put forward the application of natural potential to evaluate the effectiveness of fractured reservoirs in Hailar oilfield.Based on core analysis,geological characteristics of research,logging data,production data comprehensive analysis,in the case of low permeability,we found that the spontaneous potential anomaly is mainly caused by the effective fractures.According to the relationship between the actual production data and abnormal amplitude of the natural potential,the effective reservoir identification standard is established and practical application effect is good.The method has stronger applicability,and has guiding significance to the comprehensive adjustment of oilfield.关键词
