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。
Huoshaoshan oilfield of Junggar basin is produced from a Permian naturally-fractured sandstone raservoir.30imbibition experiments with 24 rock samples indicated that on imbibition,a stronger relationship exists between imbibi-tion time and efficiency,and imbibition capecity of rock matrix is relatively low with ultimate absorption ratio Of only10.16%, moreovcr, the relationship between oil recovery factor and imbibition capacity of rock matrix is discussed.
