摘要：为了研究致密储层静态渗吸过程中的规律及其影响因素，提高致密油采收率，利用新疆油田致密储层的天然岩心，采用自行研制的静态渗吸实验测量装置，开展了室内静态渗吸模拟实验。实验结果表明：温度升高，静态渗吸采出程度明显增加；静态渗吸采出程度与渗透率之间呈现对数关系，即在一定范围内岩心渗透率越大，静态渗吸采出程度越大。致密储层静态渗吸采出程度以两种增长趋势不断增加，相应的渗吸速率也出现两次峰
值。对实验结果进行无因次化处理和等比例关系处理，曲线归一性较好。关键词：致密储层；岩心；静态渗吸；采出程度；等比例关系

The experimental results show that with the rise of the temperature, the recovery factor of the static imbibition enhances obviously; there exits the log-log relationship between the factor and permeability i. e, within a certain range, the bigger the core permeability is, the higher the recovery factor will be, For the factors, two rising tendencies are obvious gradually, and moreover there are two peak values for the corresponding imbibition permeability. The dimensionless and isometric processes are caught out for the experimental results, the curves show much better normalized characteristic.
Key words: tight reservoir; core; static imbibition; recovery factor; isometric relationship

要接替能源。致密油藏因孔喉细小、孔隙度低，导致注人压力大，这使得常规注水很难取得良好的开发效果[45)。致密砂岩油藏通常为水湿油藏，加强
