油气普遍具有易燃、易爆及有毒等特性,在管道运输过程中,有可能因外部影响、设备设施质量缺陷或故障、人的不安全行为等原因而导致油气泄漏、扩散事故,甚至火灾爆炸等事故的发生。事故一旦发生,将可能造成人员伤亡、财产损失或环境污染。本文针对油气管道的事故类别、事故原因、事故发生的可能性、事故后果及风险进行了系统的分析。开展风险分析,有助于油气管道运输企业和安全主管部门科学地预测已建或拟建管道的事故风险程度,从而作出正确的决策,采取必要的安全措施,保障安全生产。
Oil and gas are generally flammable, explosive and toxic and other characteristics in the pipeline transportation process, there may be due to external influences, equipment and facilities quality defects or failures, human unsafe behavior and other reasons may lead to oil and gas leaks, proliferation accidents and even fire explosion The occurrence of accidents. In the event of an accident, it may cause personal injury, property damage or environmental pollution. This article systematically analyzes the types of accidents in oil and gas pipelines, the causes of accidents, the possibility of accidents, the consequences and the risks of accidents. Carrying out risk analysis will help oil and gas pipeline transport enterprises and safety authorities scientifically predict the accident risks of the existing or proposed pipelines so as to make correct decisions and take the necessary safety measures to ensure safety in production.
