Abstract

The invention relates to the technical field of a core resistivity measuring device, in particular to a full-diameter core resistivity clamp. The clamp comprises a holding cylinder, a movable plug cap, a fixed plug cap and a lead pedestal, wherein the axis of the holding cylinder is in the horizontal direction; the left part and the right part of the holding cylinder are fixedly provided with the movable plug cap and the fixed plug cap respectively; the lower part of the holding cylinder is fixedly arranged on the lead pedestal; a holding cavity capable of holding a core column is formed in the holding cylinder; a power supply electrode and a measuring electrode are fixed on the inner wall of the holding cavity; the measuring electrode can be used for measuring the resistivity of the core column; a connecting slot in which a connecting terminal is arranged is formed on the lead pedestal; and the connecting terminal is electrically connected with the measuring electrode through a wire. The clamp has a rational and compact structure and is convenient to use; the core column is protected from being influenced by external environment through the holding cylinder, the movable plug cap and the fixed plug cap; the core resistivity can be accurately measured and the core temperature can be monitored; a core is convenient and fast to assemble and disassemble; and the clamp has the characteristics of high measuring accuracy, easiness and convenience, and high efficiency.

Description

technical field [0001] The invention relates to the technical field of rock core resistivity measuring devices, and relates to a full-diameter rock core resistivity holder. Background technique [0002] Existing core resistivity measurement devices generally use the exposed quadrupole measurement method to measure the resistivity of the core. Since the measurement takes a certain time, there is no effective protection for the full-diameter core at this time, and the temperature and humidity changes in the field well site are relatively large. If the value is large, the error of the measured value obtained is large. In addition, since the temperature of the rock core cannot be measured in real time while detecting the resistivity, the error of the measured value is further increased. Contents of the invention [0003] The invention provides a full-diameter rock core resistivity holder, which overcomes the above-mentioned deficiencies in the prior art, and can effectively s...
