8.井壁锚 在新钻成的裸眼井段进行地层测试时,若测试层段不邻近井底因而不宜使用单封隔器系统,这时就需要在跨隔式地层测试系统的下部配置井壁锚装置,利用可胀开和收拢的卡紧机构把整套测试工具锚定在井壁上。井壁锚应是一种结构简单、操纵方 8. Wellbore Anchor When stratigraphic testing is performed on a newly drilled openhole section, it is not appropriate to use a single packer system if the test section is not adjacent to the bottom of the well. In this case, a well is to be deployed in the lower section of the straddle formation test system The wall anchor device anchors the entire set of test tools to the wellbore using a snap-in mechanism that expands and contracts. Shaft anchor should be a simple structure, manipulator
