Abstract

The invention relates to a pole plate scale device for a logging instrument. The pole plate scale device for the logging instrument comprises a pole plate (1) and a box body (2). First fixing structures (4) are arranged at the bottom of the pole plate (1), the lower surface of the box body (2) is attached to the upper surface of the pole plate (1) in shape, and second fixing structures (5) are arranged on the two sides of the box body (2). The first fixing structures (4) and the second fixing structures (5) are connected, so that the box body (2) is fixed on the pole plate (1).

Description

technical field [0001] The invention relates to the field of petroleum well logging, in particular to a polar plate scale device for well logging instruments. Background technique [0002] As the sensor of the micro-resistivity imaging logging tool, the plate performs scanning, data processing and other work, and is the core component of the logging tool. In the development process of the instrument, it needs to be inspected and calibrated before the instrument is tested in the well. The existing scale device is connected with the polar plate by means of a spring, and the fixation is not firm. The existing scale device cannot be closely attached to the surface of the polar plate. The probe part and the circuit part of the existing scale device are separated, which is inconvenient to use and install on site. Contents of the invention [0003] The object of the present invention is to provide a polar plate scale device, which is convenient and reliable to connect with the...
