Rock complex resistivity signal measurement device, structure and method

Abstract

The invention discloses a rock complex resistivity signal measurement device, fabrication and application method. By the rock complex resistivity signal measurement device, the problems that a measurement electrode and a sample cannot be enabled to be effectively contacted and the device is relatively poor in portability. The rock complex resistivity signal measurement device has the beneficial effects that the rock complex resistivity signal measurement device is convenient to carry, and the experiment efficiency can be effectively improved. The rock complex resistivity signal measurement device comprises a detachable container and the measurement electrode, wherein an accommodating cavity is formed in the container and is used for placing a test sample, a power supply electrode is arranged in the accommodating cavity and can be in contact with the test sample, a measurement electrode hole is formed in the container and is used for installing the measurement electrode, the measurementelectrode can be contacted with the test ample in the accommodating cavity through the measurement hole, and the measurement electrode is not directly contacted with the test sample in the accommodating cavity while is indirectly contacted with the test sample by a salt bridge solution in the electrode. The rock complex resistivity signal measurement device aims to prevent the situation that a metal electrode generates an electrode polarization effect to affect a measurement signal.

Description

technical field [0001] The invention relates to the fields of geotechnical engineering, geophysics, and hydrogeology, and in particular relates to a rock mass complex resistivity signal measuring device, structure and method. Background technique [0002] At this stage, with the rapid development of social and economic construction, the continuous improvement of people's living standards in various countries, and the rapid growth of the world's water demand, the water storage capacity and anti-seepage capacity of reservoirs are particularly important. At present, many anti-seepage materials are used to block seepage in reservoirs, but it is difficult to judge which material can better achieve anti-seepage. At this stage, the post-evaluation methods for the anti-seepage effect of the reservoir are mainly methods such as sounding and cross-hole operation in the well. In order to achieve non-destructive evaluation, it is recommended to use complex resistance method, such as ex...

Problems solved by technology

In terms of rock mass complex resistivity signal measurement, the effective contact between the measuring electrode and the measured sample can improve the signal-to-noise ratio of the measurement data, but the inventors found that the measuring electrodes currently on the market are not suitable for the measurement of rock mass resistivity signals, and cannot Ensure the effective contact between the measuring electrode and the sample, and the overall device has a low reusability rate, which can only be used in the laboratory, and has the problem of poor portability
