利用纵向驰豫时间T_1划分流体类型

Classification of fluid type by using longitudinal relaxation time T1

利用俄罗斯ＲＭＫ核磁共振测井仪器，在中国进行了２口井的纵向驰豫时间Ｔ１测量。依据测量结果，结合室内实验，借鉴俄罗斯评价技术，建立了中国的Ｒｉｐｅｄ──核磁共振测井解释模型，进行了流体类型的划分和定量计算；同时，用试油结果进行了验证，说明利用俄罗斯ＲＭＫ核磁共振测井技术能成功划分流体类型。

The measurement of longitudinal relaxation time T1is made in two wells in Chain by using the Russian RMK nuclear magnetic resonance (NMR) logging tool. On the basis of the measured results and laboratory experiments, together with the reference of Russian NMR interpretation technique, a new Riped NMR log evaluation model is provided in this paper, which can classify fluid type and calcalate quantitatively. Meanwhile, the oil test result shows that the Russian RMK NMR technique can be used to identify fluid type and evaluate the characteristic successfully.
