海洋采油平台天然气泄漏扩散实验与数值模拟分析OA

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.
