在长期测井实践中,我们发现CJ-1000型绞车的集电环由于本身结构原因,漏油严重,产生油污,致使电刷接触不良,环与环之间、环对地间绝缘低,直接影响到测井曲线的记录质量。 In the long-term logging practice, we found that the collector ring of CJ-1000 winch has serious oil spill due to its structural causes, resulting in oil pollution, resulting in poor contact of the brush, low direct-to-ground insulation between the ring and the ring, direct Affecting the logging curve of the recording quality.
