摘要
本文据阿17-7井油基泥浆取心的岩样分析数据,评价了蒙古林砾岩油层含水饱和度问题.火山角砾岩由于孔隙结构微细,物性差,含水饱和度高;砾状砂岩及砂砾岩物性好,含水饱和度低。相对含油饱和度高.
With the analytical data on rock samples recovered by drilling mud with oil matrix, water saturation of the pays in Menggulin Breccia was evaluated. Volcanic breccia is highly water-saturated due to its fine pore geometry and poor physical properties; while gravelly sandstones and sandy conglomerates are low water-saturated with relatively high oil saturation.
