Description

[0001] technical field [0002] The invention relates to the technical field of oil pipeline leakage detection, in particular to a nuclear magnetic resonance oil pipeline leakage hidden danger detector and detection method. [0003] Background technique [0004] Leakage is the main failure in the operation of oil pipelines. During the operation of oil pipelines, due to corrosion, perforation and other external force damage, leakage accidents occur from time to time, causing huge economic losses to the oil field. Therefore, leakage monitoring has not only become an important work content of oil pipeline safety production management, but also an indispensable guarantee to ensure the normal operation of pipelines. The automatic leakage monitoring technology of oil pipelines has been widely used in foreign countries, and developed countries such as the United States must adopt effective leakage monitoring systems for pipelines. The research on pipeline leak detection technol...
