使用致密砂岩克氏渗透率测定仪 ,完全克服了气体滑脱效应的影响 ,可以快速准确地测定致密砂岩的克氏渗透率。整个测试过程由微机控制 ,主要包括压力、气体流量和时间参数的自动采集、数据处理、测定结果计算和显示等 ,实现了全部测试过程的自动化 ,克氏渗透率测定范围为 5× 1 0 - 3μm2 ～ 1× 1 0 - 6μm2 。实际应用结果表明 ,该仪器是目前国内测定致密砂岩克氏渗透率的理想仪器。
The tight sandstone Kjeldahl permeability tester can completely overcome the effect of gas slippage and can quickly and accurately determine the Kjeldahl permeability of tight sandstone. The entire testing process is controlled by microcomputer, including automatic acquisition of pressure, gas flow and time parameters, data processing, calculation and display of measurement results, etc., to achieve the automation of the whole testing process. The range of Kerry’s permeability is 5 × 10 ~ 3 μm 2 to 1 × 10 6 μm 2. The practical application shows that the instrument is the ideal instrument for the determination of the permeability of tight sandstone in China.
