Problems solved by technology

But in such an environment, the advantages of micro-resistivity imaging technology no longer exist, and conventional micro-resistivity imagers cannot work well in such non-conductive mud
In most cases, the absence of microresistivity borehole imaging represents a loss of information critical to the successful development of the reservoir

Abstract

The invention relates to a pole plate electrode system for a logging instrument. The pole plate electrode system for the logging instrument comprises an insulating plate (2), a pair of emission electrode plates (3) and electric buttons (7), wherein a pair of grooves is formed in the two ends of the insulating plate (2), the emission electrode plates (3) are transversely embedded into the grooves of the insulating plate (2), the electric buttons (7) are embedded into the middle of the insulating plate (2), and the emission electrode plates (3) are symmetrically arranged relative to the electric buttons (7).

Description

technical field [0001] The invention relates to a pole plate assembly in a petroleum well logging instrument, and more particularly relates to a pole plate electrode system of the pole plate assembly. Background technique [0002] Micro-resistivity imaging logging is mainly used for fracture identification and evaluation, high-resolution thin layer evaluation, stratum deposition environment analysis, stratum intra-layer structure and structure interpretation, and core positioning and description. Using microresistivity imaging tools to log wells can obtain real and visualized high-quality borehole geological images. [0003] The micro-resistivity logging tool measures the borehole surface resistivity at a fine scale, and converts the resistivity measurement results into pixel intensity values ​​to obtain borehole wall images. Such logging tools were originally developed for use with conductive drilling fluids such as water-based muds. However, resistive drilling fluids suc...
