油气管道站场完整性管理数据模型

站场完整性数据管理所需的数据种类不断发展，数据模型作为数据管理的基础，采用针对每种具体对象建模的传统建模方式，数据要素之间关联性弱，且频繁变化的数据项造成模型不稳定，导致管理中各业务之间无法形成有效的闭环。以油气长输管道数据模型为基础，结合我国站场管道完整性管理的业务需求，提出了一种满足站场完整性管理业务需求的空间数据模型。该模型以几何网络为基础，建立管网和站场设备设施的空间拓扑关系，同时考虑定制和扩展性能，以满足对新技术、新方法的支持。结合该模型在某大型油气管道站场的应用，论述了其应用效果，具有较强的实际指导意义。

Data model for the station integrity management along oil and gas pipelines

Data for stations （pump stations or gas compressor stations） integrity management are increasingly diversified. As a basis for the data management, data model employs traditional techniques which are specific for certain objects. However, the correlation between data elements is weak, and frequently changing data items result in the instability of model. Ultimately, an effective closed loop can not be formed among different operations in the management, In this paper, considering the demands for the domestic station integrity management, a corresponding spatial data model is proposed based on the data model of long-distance oil or gas pipeline. This geometric network-based model can be used to generate topological spatial relations between pipeline network and equipment/facilities at pump stations or gas compressor stations. Its functions may also be customized and extended as a response to new technologies or methods. The application in a large pipeline network-station of PetroChina has proved the effects of the model, providing valuable guidance for other cases.
