| 英文摘要 | The safe and stable operation of the salt cavern gas storage well site makes a positive contribution to the safety of natural gas transportation and emergency peak balancing. In order to reduce the influence of gas leakage and diffusion accident of salt cavern gas storage well site, a quick and high accurate method of locating leakage source and monitoring leakage diffusion is proposed. Combining the advantages of laser methane monitoring equipment with high precision and fast response, the leakage source is identified and located by mathematical model. Firstly, the laser methane detection sensor is rationally arranged based on the monitoring point layout model of leakage risk probability. The multi-point monitoring data are analyzed in real time and the data interpolation algorithm is used to predict the gas leakage and diffusion state of the unknown region. Then, combining the monitoring points and data interpolation points, a mathematical model is built to identify and locate the leak source. Finally, by using the field simulation test data and comparing with the numerical simulation method, it is verified that the real-time monitoring accuracy of natural gas methane leakage obtained by this method can reach 1 ppm, with high sensitivity and fast response. Compared with the technical means of manual assisted leak location, this method can effectively solve the difficult problem of leak monitoring and location of salt cavern gas storage well site, reduce the expansion and impact of leakage accidents in time, and realize the rapid analysis of salt cavern gas storage well site leakage risk and safety monitoring management. |
