在研究吐哈盆地柯柯亚地区致密砂岩孔渗数据和压汞曲线特征参数的基础上,提出利用最大进汞梯度峰值,结合起始排驱压力和岩心孔隙度等参数,作为评价致密砂岩孔隙结构的重要指标,建立了一套适合吐哈盆地致密砂岩孔隙结构的新方法和思路,取得了较好的评价效果。 Based on the study of the pore-infiltration data and the mercury injection curve of the tight sandstone in Kekeya area, Turpan-Hami basin, it is proposed to use the maximum peak of mercury intrusion gradient, combined with the initial displacement pressure and core porosity, A set of new methods and ideas that are suitable for the pore structure of the tight sandstone in the Turpan-Hami basin have been set up and important evaluation results have been achieved.
