Abstract

The invention discloses a non-polarized receiving electrode structure which comprises a base body electrode, a lining is fixedly arranged on the base body electrode in a sleeving mode, and a receiving electrode is fixedly arranged on the outer side of the lining in a penetrating and sleeving mode. An insulating sleeve fixedly sleeves the base body electrode and is arranged at the end parts of the receiving electrode and the lining. An inclined hole is formed in the receiving electrode and is far away from one end of the insulating sleeve; the pressure-bearing sealing plug is fixedly installed in the inclined hole, the binding post is arranged in the lining, one end of the binding post is connected with the receiving electrode, and the other end of the binding post is connected with the pressure-bearing sealing plug through a connecting wire. The receiving electrode adopts a non-polarized electrode. According to the invention, the bushing is arranged on the substrate electrode, the receiving electrode sleeves the bushing, and the insulating sleeve is used for fixing the receiving electrode and the bushing, so that isolation between the receiving electrode and surrounding metal is ensured; and the receiving electrode adopts the non-polarized electrode, so that the influence of an environmental solution is avoided, the accuracy of acquired data is high, the measurement precision is greatly improved, and disassembly and replacement are convenient.

Description

technical field [0001] The invention belongs to the technical field of mineral deposit detection instruments, and in particular relates to a non-polarization receiving electrode structure. Background technique [0002] In the field of oil and metal deposit exploration, electrical instruments are usually used to analyze and determine the material content in the formation; when the electric instrument transmits current through the formation, the current signal is collected by the receiving electrode, and the material content contained in the formation is determined through analysis; in the past The receiving electrode of the electric method instrument is generally made of stainless steel or lead skin; the disadvantage is that the stainless steel or lead skin itself will generate a polarization potential in the solution, resulting in inaccurate received potential signals collected. Contents of the invention [0003] Aiming at the technical problems existing in the prior art, ...
