１　前言随着对油田安全生产的日益重视，对油气生产厂、站、库的消防设施的标准也提出了更高的要求。在油田消防设计中，发现油田有些中小型站场分布广，距离消防站较远，使用消防车扑救有困难，若这些站场建固定消防设施，投资大，经济上是不合理的，必须考虑一套经济合理的 1 Introduction With the increasing emphasis on safe production of oil fields, higher standards have been set for the standards of fire-fighting facilities for oil and gas production plants, stations and warehouses. In the oilfield firefighting design, it was discovered that some small and medium-sized stations in the oilfield are widely distributed and are far from the fire station. It is difficult to use fire engines to fight against them. If these stations are built with fixed firefighting facilities, the investment is large and economically unreasonable. It must be considered. A set of economically sound
