Large number of core analysis results showed that 100 psi as the best centrifugal force of calibrating T_2 cutoff value might be not suitable for glutenite cores have low porosity and low permeability and special lithological cores such as carbonatite cores and vulcanite cores.

大量岩心分析实验结果表明,100psi作为标定岩心T_2截止值的离心力对低孔、低渗砂砾岩岩心以及碳酸岩、火山岩等特殊岩性岩心而言可能不适用。

Under best centrifugal force, author selected a lot of representative Glutenite、carbonatite and vulcanite cores and carried on centrifugal experiments and NMR T_2 measurement, and determined T_2 cutoff value of each cores, This *** also selected a certain amount of representative fresh oil-bearing sandstone for calibrating T_2 cutoff value, and analyzed influence of T_2 cutoff value with original wettability of core.

在最佳离心力下,本文选取了大量有代表性的砂砾岩、碳酸岩和火山岩岩心进行了离心实验和核磁共振T_2丈量,确定出了对应岩心T_2截止值大小,本文还选取了一定数目有代表性的新鲜含油砂岩湿样进行了T_2截止值标定,分析了岩心原始润湿性对T_2截止值的影响。

Each of cores were carried on NMR measurement after each of six or seven different centrifugal force, author can got that 200 psi was suitable to be best centrifugal force calibrating T_2 cutoff value for glutenite cores, and 400 psi was suitable for carbonatite and vulcanite cores in this ***, and corresponding lower limit of valid throat is 0.1μm for glutenite and 0.05μm for carbonatite and vulcanite.

对本文实验选取的岩心而言,低孔、低渗砂砾岩岩心T_2截止值标定时适合的最佳离心力均大致可取200psi,而碳酸岩和火山岩岩心最佳离心力均大致可取400psi,对应的有效渗流喉道半径下限砂砾岩为0.1μm,碳酸岩和火山岩为0.05μm。

In this ***, T_2 cutoff value of glutenite cores mostly distributed between 10 and 30 ms, carbonatite cores were about 100ms. T_2 cutoff values of vulcanite cores changed great with lithology, and average T_2 cutoff value of rhyolite cores was 87.91 ms, tuff was 52.02 ms, and volcanic breccia was 36.28 ms.
