Long core pressure measuring holder

The utility model discloses a long rock core pressure measuring clamp holder. The long rock core pressure measuring clamp holder is provided with a plug I, a barrel body, an annular pressure cavity, a rubber sleeve, a long rock core, a plug II, a pressure measuring probe, an electromagnet, a push rod, a limiting piece, a reset spring, a limiting step, a pressure sensor, a buffer pad and a probe. And the buffer pad is arranged on the limiting step to prevent the probe from extending too much to cause damage to the rock core. According to the utility model, the plurality of pressure measuring probes are arranged to realize the real-time monitoring of the axial pressure in the long core displacement process, so that the pressure distribution rule and the dynamic change characteristics can be conveniently researched. 本实用新型公开了一种长岩心测压夹持器，所述长岩心测压夹持器设置有：堵头Ⅰ、筒体、环压腔、胶套、长岩心、堵头Ⅱ、测压探头、电磁铁、推杆、限位片、复位弹簧、限位台阶、压力传感器、缓冲垫、探针。所述缓冲垫置于所述限位台阶之上，防止探针伸长过多导致岩心破坏。本实用新型通过设置多个测压探头可实现长岩心驱替过程中轴向压力实时监测，便于研究压力分布规律及动态变化特征。
