延长油田是油气资源的生产和储运企业,为了保证油品存储系统稳定安全运行,减少油品损失,改善油区生产环境,对油库进行蒸发损耗量的测试是非常必要的。本文选用了适合延长油田的油气损耗计算公式以及数据计量的方法,为找出油气损耗的主要原因和日后油气回收工作做好铺垫。 Yanchang Oilfield is a production and storage enterprise of oil and gas resources. In order to ensure stable and safe operation of oil storage system, reduce oil loss and improve oil production environment, it is necessary to test evaporation loss of oil depot. In this paper, the calculation formula of oil and gas loss and the method of data measurement, which are suitable for extending the oilfield, are selected to pave the way for finding out the main reason of hydrocarbon loss and future oil and gas recovery.
