摘要:
储层的孔?喉连通性是致密砂岩储层评价过程中所用到的一个重要参数,而孔?喉连通性的研究受到致密砂岩储层复杂的纳米喉道影响,其量化手段单一、表征参数不明,是当下该研究领域中的难点.为进一步完善储层连通性的表征手段,利用纳米CT技术、核磁共振冻融技术以及三离子束刻蚀结合场发射扫描电镜?PCAS(Pores and Cracks Analysis System)技术,从定性和定量两个角度对于鄂尔多斯盆地延长组7段典型(粉砂、细砂、泥质粉砂)致密砂岩样品的连通性进行不同尺度的表征分析.实验结果表明,致密砂岩孔隙的孔径大小与其所沟通的喉道数目呈正相关;致密砂岩中连通孔隙的体积对于连通性的贡献远高于连通孔隙的数目;油浸的细砂岩样品其连通性高于油斑的粉砂岩样品.实验分析认为,多方法联用的表征方法是致密砂岩储层连通性刻画的重要手段.
