Abstract

The invention belongs to the technical field of petroleum geological prospecting instrument supporting equipment, and particularly relates to a pressure bearing pole plate for a logging instrument. According to the pressure bearing pole plate for the logging instrument, the pressure bearing problem that a pole plate is internally provided with a cavity and related measuring device pole plates needto be arranged internally can be effectively solved. The pressure bearing pole plate for the logging instrument includes a pole plate bottom casing, the two ends of the pole plate bottom casing are provided with an upper joint and a lower joint respectively, a pressure bearing plug is inserted at the position of an opening of the upper joint, an upper pole plate casing is mounted over the pole plate bottom casing, and an electrode is mounted on the upper pole plate casing. An upper oil injection port is disposed at the position of the upper joint, and a lower oil injection port is disposed atthe position of the lower joint. The upper oil injection port and the lower oil injection port are respectively communicated with an inner cavity formed after the installation of the pole plate bottom casing and the upper pole plate casing is completed.

Description

technical field [0001] The invention belongs to the technical field of supporting equipment for petroleum geological exploration instruments, and in particular relates to a pressure-bearing polar plate of a well logging instrument. Background technique [0002] At present, some well logging tool plates need to embed the preamplifier circuit and even all the measurement circuits in the cavity inside the plate. For example, the pole plates of water-based mud electrical imaging logging tools generally use metal steel shells as pressure-bearing shells, relying on the high mechanical strength of metal materials to provide pressure-bearing capacity. In recent years, there are also logging instrument prototypes in China that have entered the experimental stage. The pressure-bearing structure of the measuring plate still adopts the same metal shell pressure-bearing structure as the water-based mud electric imaging plate. For this kind of metal shell plate, when the plate area is la...
