摘　　要：岩心夹持器是一种用于夹持和密封岩心,完成各种岩石物理性质测试及相关实验的装置。文章介绍的岩心夹持器采用气压密封方式,夹持器上端设有一密封气体入口,支撑杆置于密封套内,密封气体进入夹持器缸套与岩心密封套之间的腔体,对待测岩石样品侧表面施加均匀围压,确保测试流体通过岩心样品前后两端时无测试流体渗漏。该岩心夹持器具有密封效果好,装取样品方便,结构简单,安全防爆且使用寿命长的特点。Core holder is a device used to hold the core and seal side face of the core on testing procedure of core physical feature and so on. The holder introduced here take method of gas sealing, a hole on side face of core holder is sealing gas passageway, the support stick laying in rubber sleeve, pressured gas fill in the cave between holder’s inner side and sleeve, thereby equality sealing core side ensuring no seepage of testing liquid or gas through two end of core. Characteristic of the holder is fine sealing, easy loading and unloading sample, simple structure, safety and long life, so it has wildly application in permeability test and driver-displacement test on all kinds of core sample. The device has granted patent.
