Embodiment Construction

[0014] The electrode setting is performed on the rock core to be tested in advance, and then an insulated wire of appropriate thickness is used to connect the electrode. The number of electrodes and wires can be connected up to 16. Fix the bottom part on the workbench, pass 8 wires through the lead-out holes on the bottom part respectively, and fix the rock core in the ring of the bottom part. Then pass the remaining 8 wires through the lead-out holes on the top part, adjust the size of the upstream and downstream fluid injection chambers by adding spacers as needed, and install the top part.

[0015] Fit the upper sleeves around the core and on the rings of the top and bottom end pieces. The surface of the rock core after the electrodes and wires are installed will be uneven, which can be eliminated by injecting glue, so as to realize the dense connection between the rock core and the sleeve.

[0016] Add a sealing ring to the top and bottom parts, put the upper confining p...

Abstract

The invention relates to a special rock core holder for high-density electrical parameter monitoring, which belongs to the technical field of permeability measurement in the fields such as hydrogeology, geological engineering, petroleum geology, hydrology and water resources, soil science and mineral resources, solves a problem that it is difficult to carry out high-density monitoring on electrical parameter changes in the experimental process on the same rock core and provides an important means for obtaining permeability parameters of the same rock core in different scales and directions oreven under heterogeneity. The technical scheme is that the holder is internally provided with a special sleeve installation lantern ring, the lantern ring is provided with a plurality of wire leading-out holes, high-density monitoring for the electrical parameters of the rock core is realized through the connection between wires and electrodes on the surface of the rock core, and the part betweenthe sleeve and a confining pressure cylinder is a confining pressure chamber which is used for applying and monitoring the confining pressure. The special rock core holder has extensive applications in high-density medium electrical parameter monitoring carried out under different confining pressure and the research and application of understanding the seepage process of a fluid in the medium andextracting relevant parameters.

Description

technical field [0001] The core holder is a special device for core measurement experiments. It fixes the core, provides channels for the application and measurement of pore pressure, confining pressure, etc., and measures the permeability and related parameters of the core. It is a core device in the experiment. Since the permeability is an important basic parameter in the fields of hydrogeology, geological engineering, petroleum geology, hydrology and water resources, soil science, mineral resources, etc., and is an important input variable for subsequent simulation calculations, the core holder has also become a part of this technical field. a core component of . The traditional core holder only provides the functions of fixing the core and applying and measuring pressure, while the invented core holder not only has these traditional functions, but also provides high-density electrical parameter monitoring The channel creates conditions for the use of high-density electri...
