摘　　要：成品油管线在运营过程中会发生泄漏，主要原因为管线腐蚀、外力撞击、打孔盗油及水击等，泄漏后油品蒸发扩散形成的爆炸性区域具有很大的危险。通过小孔泄漏模型和大面积泄漏模型对地面管线发生泄漏事故形成的油品蒸气扩散情况进行了分析计算，获得了油品泄漏后距泄漏点的安全距离，计算数据可对管线的抢修提供参考。Oil gas diffusion can probably occur from the product pipeline due to some factors such as pipe corrosion, foreign power collision,oil stolen by drilling hole or water hammer. Dangerous space will be formed by oil diffusion. Diffusion is analyzed and calculated with little leakage model and large leakage model in his article, safe distance from the leakage point is calcalated after the leakage,calculated results can provide some advice for the repair of pipelines.
