摘　　要：基于中国石化胜利油田典型海洋平台,搭建缩比为1∶22的实验平台,选取储罐、天然气处理系统及三相分离器等设备作为气体泄漏源,开展基于Froude数相似理论的甲烷泄漏扩散规律测试实验,同时,采用泄漏及爆炸分析软件FLACS建模,进行典型泄漏工况的数值模拟。通过气体泄漏实验和数值模拟结果对比,两组数据的总平均误差为8.70%,验证数值模型具有较好的预测精度;结合数值模型和实验数据,进一步分析了海洋平台甲烷泄漏的扩散规律,为海洋平台油气泄漏安全风险防控提供了理论和数据支撑。Based on a typical offshore platform of SIN-OPEC Shengli Oilfield,an experimental platform with a reduction ratio of 1∶22 was built.Equipment such as storage tank,natural gas treatment system,and three-phase separator were selected as gas leakage sources to conduct the methane leakage diffusion law testing experiments based on the Froude numerical similarity theory.At the same time,leakage and ex-plosion analysis software FLACS was used to model,and numerically simulation of typical leakage condi-tions was carried out.By comparing the results of gas leakage experiment and numerical simulation,the to-tal average error of the two groups of data was 8.70%,which verified that the numerical model had good prediction accuracy.Combined with numerical model and experimental data,the diffusion law of methane leakage on offshore platforms was further an-alyzed,which provided theoretical and data support for the prevention and control of oil and gas leakage safety risks on offshore platforms.
