摘要
恒速压汞技术不仅可测量喉道数量,还能准确直接测量孔隙和喉道的大小及分布,有助于直观、定量地表征储层的孔喉特征。主要从喉道、孔隙以及喉道和孔隙的配置关系等方面对苏120区块储层微观孔隙结构进行分析。结果表明,孔隙大小对渗透率影响较小,喉道大小及其分布影响孔隙结构的微观非均质性,喉道特征是决定储层物性的关键因素。
Constsp mercury penetration technology not only can measure number of throat, also can directly measure the size and distribution of pore and throat, help to intuitive, quantitative characterization of reservoir pore throat characteristics. Mainly from the throat and pore throat and pore configuration of the relationship of Sue 120 block reservoir micro pore structure is analyzed. The analysis has demonstrated that the size of the pore has little effect on permeability, throat size and its distribution influence the microscopic heterogeneity of pore structure and throat characteristic is the key factor that determines reservoir property.
