Pipeline leakage detection system and method using negative pressure waves

Abstract

The invention provides a pipeline leakage detection system and method using negative pressure waves, and relates to the field of oil pipeline leakage detection. According to the system and method, time synchronization of pressure data is achieved accurately through pressure sensors, GPS units and data synchronizers which are arranged at all stations of pipelines; a PLC collecting unit transmits pressure data subjected to time synchronization to an SCADA server; the SCADA server assembles the pressure data of all the stations and provides a remote access interface; the data is uploaded to a leakage detection server through the access interface, so that the stability of data transmission is guaranteed, sending of a pressure data read failure is avoided, and the reliability and the accuracy of the pressure data are guaranteed; and finally the leakage detection server finishes judging and matching of the pressure data as well as the detection positioning, leakage detection among multi-station pipelines is achieved, and the accuracy of the final computed result is improved.

Description

technical field [0001] The invention relates to the field of oil pipeline leakage monitoring, in particular to a negative pressure wave pipeline leakage monitoring system and method. Background technique [0002] With the large-scale investment and construction of oil and gas pipelines brought about by the rapid development of my country's economy, the problems of leakage, blockage and defects of oil and gas pipelines have become increasingly serious. At present, most of the long-distance oil pipelines in domestic oilfields are not equipped with automatic leakage detection systems. The operation data is read manually, which is very detrimental to the safe operation of the pipeline. It is estimated that the output value of oil and gas pipeline leakage monitoring and detection systems alone will be close to 100 billion. In the long run, the pipeline leakage monitoring industry needs more reliable and effective technical means and products to ensure the real-time, accurate and ...
