用法例句

Investigation in setting technology of hydraulic packer in horizontal holes;

水平井用液压封隔器坐封工艺技术研究

The rubbers in hydraulic packer can swell up and contact with the casing wall under hydraulic action.

液压封隔器是通过水力作用使胶筒在套管环空内鼓胀 ,而与套管内壁接触并产生一定接触压力 ,克服了封隔器上、下套管环空液流产生的压差 ,达到分层目的。

The process pipe string of hydraulic packer used in water shutoff and layering is widely applied because its performance is very advanced.

采用液压封隔器卡水、分层的工艺管柱由于其先进性必将会越来越广泛地得到应用。
