摘　　要：为解决我国目前成品油二次配送环节损耗量巨大的问题,分析了在旧管理模式下,即罐车油品质量计量交接模式下成品油二次配送环节的现状及产生非正常损耗的原因。研究制定了通过采取加油站地罐体积计量交接管理模式治理成品油二次配送环节损耗的方法,论述了实施应具备的条件、地罐标定的方法选择、加油站接卸油品流程设计、可能存在的问题及避免措施等具体问题。从制度上最大程度地减少人为因素的影响,堵塞管理漏洞,使二次配送运输损耗率由之前0.7%左右的不可控状态降低到0.2%甚至更低的合理、可控范围。理论与事实证明,加油站地罐体积计量交接管理模式是一种科学、有效的管理模式。Currently, the secondary distribution of products oil in China suffers a huge amount of loss. In this paper, the current situation of such sector and the causes for abnormal loss under the old management model（i.e. the mass custody transfer metering model for tanker） are analyzed, and the method to prevent loss by the ground tank with the volume custody transfer metering model at gas station is developed. Some specific aspects are discussed, such as prerequisites for applying this method, selection of ground tank calibration approach, design of loading/unloading process at gas station, potential issues and preventive measures. In this way, relevant regulations are improved to minimize the impacts of human factors and reduce the management gaps. As a result, the loss in secondary distribution can be reduced from about 0.7%（uncontrolled） originally to 0.2% or a reasonable and controllable lower range. It’s proved theoretically and practically that the ground tank volume custody transfer metering model at gas station is scientific and effective.
