Abstract

The invention discloses a rock core resistivity measuring device with variable cavity length and real-time temperature loading, which relates to the technical field of rock core resistivity measurement, and mainly structurally comprises a box body, a movable heat preservation box, a heating rod, a temperature sensor and a temperature adjusting knob. The movable heat preservation box is movably arranged on one side of the box body, the heating rod and the temperature sensor are arranged in the movable heat preservation box, and the temperature adjusting knob is electrically connected with the heating rod. A first electrode is arranged on the other side of the box body, and a second electrode is arranged on the side, away from the box body, of the movable heat preservation box. Therefore, the real resistivity of a rock core specimen in different temperature environments can be measured. The position between the box body and the movable heat preservation box is adjustable to change the distance between the electrodes at the two ends, so that the device adapts to rock core test pieces with different lengths, and the real resistivity of underground rock is measured.

Description

technical field [0001] The invention relates to the technical field of rock core resistivity measurement, in particular to a rock core resistivity measuring device with variable cavity length and real-time temperature loading. Background technique [0002] With the continuous consumption of mineral resources, the shallow resources are basically explored and developed. Currently, the exploration and development of mineral resources are carried out in the deep. Electromagnetic prospecting technology is an important technical means for deep mineral resource exploration. The technical premise of electromagnetic prospecting is to fully grasp the resistivity distribution characteristics of deep rocks. [0003] Studies have shown that the real resistivity value of underground rocks has a certain relationship with the temperature of the rocks. The resistivity of rocks dominated by electronic conductivity increases with the increase of temperature, while the resistivity of rocks dom...
