摘要: 致密砂岩储层评价方案是识别储层"甜点"的基础,也是致密油勘探的重点和难点,但目前国内对此尚无统一认识。为此,以松南中央坳陷区泉四段致密砂岩为例,综合常规压汞、恒速压汞、高压压汞等多种资料对致密储层微观孔喉结构进行了精细表征,并以此为基础建立了致密砂岩储层评价方案。结果表明:研究区致密砂岩孔喉小、物性差,储集空间以次生溶孔为主;储层渗透性主要由占小部分体积的最大孔喉半径所控制,喉道半径越大、大喉道所占比例越高,致密储层的渗透率(K)就越高、品质就越好。在此基础上,由孔喉结构的差异性出发,将松南中央坳陷区泉四段致密砂岩储层分类4类,其中,石油能够充注至Ⅰ-Ⅲ类致密储层,且Ⅰ类致密储层(K为(0.1~1.0)×10-3 μm2)品质最高,可视为储层"甜点"。
