油气田地面施工设计涉及到石油天然气的采集、处理、输送等一系列生产过程。这些生产过程由于涉及高温、高压以及易燃、易爆、有毒有害物品等危险因素,可能会发生因设备、容器、管线、阀门泄漏及破裂而引起的石油天然气燃烧、爆炸以及硫化氢中毒等事故。为防止此类事故的发生,减轻事故危害 Oil and gas field construction design involves the collection, processing, transportation and other series of production processes of oil and gas. Due to the high temperature, high pressure and other dangerous factors such as flammable, explosive and poisonous and harmful substances, these production processes may cause accidents such as burning of oil and natural gas, explosion and hydrogen sulfide poisoning caused by equipment, containers, pipelines, valve leakage and rupture . In order to prevent such accident from happening, reduce the accident hazard
