Embodiment Construction

[0030] In order to make the purpose, technical solution and advantages of the present invention more clear, the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

[0031] The embodiment of the present invention provides an electrical imaging measurement probe, which includes a base body 1 and a single-core electrode 2. The base body 1 is provided with a pin hole. The single-core electrode 2 includes a metal electrode 3 and an insulator 4. The single-core electrode 2 is installed on the base body. In the pin hole on 1, each single-core electrode 2 can be disassembled separately, which solves the disadvantage that the entire measuring probe must be replaced when a certain electrode on the measuring probe fails, and greatly saves the cost. ...

Abstract

The embodiment of the invention provides an electric imaging measurement probe which comprises a base body and single-core electrodes. Contact pin holes are formed in the base body. The single-core electrodes comprise metal electrodes and insulators and are mounted in the contact pin holes in the base body. In addition, the electric imaging measurement probe further comprises a protective cover plate, a through hole is formed in the protective cover plate, and the protective cover plate is fixed to the base body and shields at least part of the insulators. According to the electric imaging measurement probe, the problems that in the using process of a measurement probe, cracks are prone to being generated on insulators, the insulation sealing property is prone to being damaged are solved,and thus the good imaging measurement effect is obtained.

Description

technical field [0001] The invention relates to the field of drilling measurement, in particular to an electrical imaging measurement probe. Background technique [0002] The current electrical imaging measurement probe uses glass sintering technology for the single-core electrode. When the glass sintering interface is directly exposed to the harsh working environment, the single-core electrode will crack when it is subjected to vibration shock and friction with the well wall, resulting in insulation of the measurement probe. The performance and sealing performance is reduced, which in turn affects the imaging measurement effect. Contents of the invention [0003] In order to solve the above technical problems, an embodiment of the present invention provides an electrical imaging measurement probe, which solves the problems that the measurement probe is prone to cracks and the insulation and sealing performance is easily damaged during use, so as to obtain good imaging mea...
