在油田开发建设中,为了收集和贮存生产出来的大量原油和油田气,全油田到处敷设和设置了纵横交错的油气集输管线与大量的工艺设备。而这些管线和设备,在集输、贮存加热后的油气介质时均消耗大量的热能,因此,为了大幅度降低燃料消耗,节省能源,减少经营费用,采取保温措施是非常必要的。在油田内油气集输管线保温工程所消耗的费用及劳动力在整个集输工程中占的 In the development and construction of oil fields, in order to collect and store a large amount of produced crude oil and oil field gas, a criss-crossing oil and gas gathering pipeline and a large number of process equipments are laid and installed throughout the oil field. However, these pipelines and equipments consume large amounts of heat when collecting, transporting, and storing the heated oil and gas medium. Therefore, in order to significantly reduce fuel consumption, save energy, and reduce operating costs, it is necessary to adopt insulation measures. Costs and labor consumed in the thermal insulation project of oil and gas gathering pipelines in oil fields accounted for the entire gathering project.
