核磁共振测井在川西凹陷中生界储层评价中的应用

Application of nuclear magnetic resonance(NMR)log on evaluation of Mesozoic reservoir in Chuansi sag

  • 摘要: 分析了川西凹陷中生界的储层特点,介绍了核磁共振测井的原理、方法和优点,并给出了应用实例。该技术弥补了常规测井资料进行气层评价时,无法确定储层中是否含束缚水、束缚水的体积、可动流体体积及渗透率大小等缺陷,能较准确地计算孔隙度和渗透率,划分产层、干层和水层,提高川西凹陷中生界含气砂岩测井解释精度。

     

    Abstract: Compatible with the characteristic of Mesozoic reservoir in Chuanxi sag.the principle,method and advantages of NMR are provided with examples of application.The meth- od compensates conventional logging data for the shortages as whether the reservoirs contain bound water,how much the volume of the bound water is and how many the permea- bility is.The NMR log is superior in the accurate calculation of porosity and permeability,and the classification of pro- duction horizon,dry layer and water yield layer,thus enhan- cing the precision of logging interpretation of the Mesozoic gas sandstone in Chuanxi Basin.
