The properties of waterabsorbing and water treeing in polyethylene and polyethylene modified samples were studied.
对聚乙烯及改性聚乙烯的吸水特性和水树形成规律进行了研究。

Perforation is the last step of well completion, so injection well perforation completion has great influence on waterabsorbing capability.
射孔是完井工艺最后的一个环节，因此注水井射孔完井的优劣对其吸水能力的影响就显得十分重要。
