The target layer of the offshore L area belongs to the offshore ultra-low permeability reservoir.To accurately classify and evaluate the reservoirs and guide the selection of favorable reservoir areas,based on the statistical reference of the existing classification and evaluation results of low-permeability reservoirs,combined with the characteristics of low-permeability reservoirs in the target area,the classification and evaluation parameters of low-permeability reservoirs were determined,and the comprehensive classification coefficient method was adopted to complete the classification and evaluation of low-permeability reservoirs and the selection of favorable areas.The results show that Class Ⅲ reservoirs are mainly developed in the target layer of L area,followed by Class Ⅳ and Ⅴ reservoirs,Class Ⅰ and Ⅱ reservoirs are not developed,and the contiguous distribution area of Class Ⅲ reservoirs is a favorable area for reservoir development.The research results can better guide the selecting favorable areas for reservoir development.
