摘要: 对准噶尔盆地大烧山油田二叠系裂缝性砂岩油藏的24块岩样所作的30次渗吸实验结果表明:在渗吸过程中,渗吸时间和渗吸效率之间存在较强的规律性;基质岩块的渗吸能力较低,最终吸收率仅为10.16%。探讨了油田采收率与基质岩块渗吸能力的关系。

Abstract: Huashaoshan oilfield of Junggar basin is produced from a Permian naturally-fractured sandstone reservoir.30 imbibition expetiments with 24 rock samples indicated that on imbibition, a stronger relationship exists between imbibition time and efficiency, and imbibition capacity of rock matrix is relatively low, with ultimate absorption ratio of only 10.16%, moreover, the relationship between oil recovery factor and imbibition capacity of rock matrix is discussed.
