An inflatable drill-string packer was used at Site 839 to measure the bulk in-situ permeability within basalts cored in Hole 839B. The packer was inflated at two depths, 398.2...在839站位（Site 839），研究人员采用充气式钻杆封隔器（inflatable drill-string packer），对839B钻孔（Hole 839B）获取的玄武岩岩心的原位整体渗透率开展测量。该封隔器分别在398.2……两个深度处完成充胀。
