Description

technical field [0001] The invention relates to the technical field of mud resistivity measuring devices, and relates to a mud resistivity measuring device. Background technique [0002] Existing mud resistivity measuring devices generally use the electrode and mud exposed quadrupole measurement method to measure the resistivity of mud. Due to its poor heat preservation and moisturizing performance, the error of the measured value obtained is relatively large. In addition, since the temperature of the mud 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 mud resistivity measuring device, which overcomes the above-mentioned deficiencies in the prior art, and can effectively solve the problem of large measurement errors existing in the existing mud resistivity measuring device. [0004] The technical solution of the present invention is achieved t...
