| 摘 要： | 为了定量评价储层可动油饱和度及渗流能力,应用核磁共振技术对丘陵油田40块岩心的可动油饱和度进行了定量测试.研究表明,丘陵油田低渗透储层可动油饱和度值的分布范围是4.8%~56.7%,平均值为33.4%.可动油饱和度高低与岩心孔隙度、渗透率及驱油效率呈正相关关系.各类储层可动油饱和度差异较大,储层沉积微相及物性决定了可动油饱和度和渗流能力的大小.

| Abstract: | We quantatively analysed 40 core samples in Qiuling oilfield with the nuclear magnetic resonance technology in order to quantitatively estimate the movable oil saturation in reservoirs and its flowing capability.Our research shows that the movable oil saturation in Qiuling oilfield ranges from 4.8% to 56.7% with an average value of 33.4%.The value of movable oil saturation has a positive correlation with core porosity,core permeability and liquid displacement efficiency,and it changes greatly between different types of reservoirs.Sedimentary microfacies,physical properties and microstructures of pores of the reservoirs determine the movable oil saturation and the flow capability of oil through reservoirs. |
