目前，对于东海西湖凹陷中高孔隙储层的测井评价已经取得了丰富的经验，而中低孔隙储层的测井评价尚处于探索试验阶段，是未来重点研究的目标。此文以近期探井所取得的多种测井资料为基础，对中低孔隙储层的测井响应特征进行了分析，研究地层的孔、渗、饱及孔隙结构特征，寻找岩石的孔隙结构特征与渗透率、产能之间的规律，直接评价低渗储层。

Up to now, the logging evaluations of medium-high porosity reservoirs have gained wealth experiences in Xihu sag in East China Sea. However, how to evaluate medium-low porosity reservoirs, which are becoming key objects in the future, is still in the experimental and exploratory stage. Based on the logging data from the recently exploratory wells, we analyzed the logging response characteristics of medium-low porosity reservoirs, studied the porosity, permeability, saturation and pore structure characteristics of the reservoirs, searched for the relationship among the pore structure, permeability and production ability, and eventually achieved the goals of evaluating the low permeable reservoirs directly.
