Intelligent ball technology is a new technology to detect pipeline leakage in recent years. Its working principle is to use the acoustic signal generated by pipeline leakage to locate and determine the pipeline leakage point through the analysis of collected data. Because the intelligent ball is easy to be blocked after being put into use

which leads to the accident of pipeline pressure suppression and leakage

it is necessary to analyze risks and formulate perfect risk prevention and control measures before use. Through practice

the application of intelligent ball detection technology in Ansai oil field has no leakage point

and the oil pipeline has good heat preservation effect

but there are sediments in the pipeline and the pipeline fluid flow field is complex

including laminar flow

turbulent flow and slug flow. The comprehensive analysis can show that the intelligent ball technology has good sensitivity

strong adaptability and long-distance detection.
