摘要： 利用核磁共振无损检测技术对一百余块低渗、特低渗透岩样进行了可动流体相对体积的实验测试。分析结果表明,可动流体相对体积与渗透率和驱油效率之间存在很好的相关关系:渗透率越高,可动流体相对体积越大,但在低渗透率段,又不完全受渗透率控制;可动流体相对体积越高,驱油效率也越高。最后,建立了可动流体相对体积储量分级评价标准,并对大庆、长庆低渗透油藏开发效果进行了分析对比。

Abstract: Relative volume percentage of movable fluid of more than one hundred of super-low permeability core samples is tested by using nuclear magnetic resonance technique. The results indicate that there exist good correlation between the percentage and permeability and oil displacement efficiency. The higher permeability, the bigger the percentage is, except for low permeability condition; the bigger the percentage, the higher the oil displacement efficiency is. Based on these, this paper suggests the classifying criterion of reserves by the relative volume percentage of movable fluid, by which the development effects of low permeability reservoirs between Daqing and Changqing fields are analyzed and correlated.

Key words: movable fluid, relative volume percentage, low permeability reservoir, development effect, nuclear magnetic resonance
