摘要
干线管道的可靠性是一种由若干单项属性组成的综合属性,它包括无故障性、可维修性、耐久性、工况可控性、生命力和安全性。干线管道运行的可靠性在很大程度上取决于外部条件:一方面是自然环境的作用;另一方面是油气开采系统和油气处理系统的工作能力,还包括满足用户向运输企业提出的要求。在设计干线管道时,要对情况进行综合分析,即不仅要研究管道本身,而且要研究工艺相关项目对管道的影响。干线管道通过能力、动力设备可靠性指标和维护参数等是实际设计工作中可靠性指标的预测信息,量化到具体设计工作,就要考虑油(气)站分析、输送设备规格型号和输送设备连接方式的具体特点,必要时可对各站的设备可靠性指标进行具体化和精确化。根据俄罗斯现行采用的可靠性设计指标,分别对管道通过能力等一系列参数进行了计算。
The reliability of main pipeline is a comprehensive attribute consisted of several individual attributes, including fail-safety,maintainability,durability,controllability,lifetime and safety. To a great extent,the operating reliability of the main pipeline depends on the external conditions:on the one hand,it is the impact of physical environment,and on the other hand,it is the operating capability of production and processing systems of oil and gas, and the transportation enterprises should also meet the requirements of users. The authors consider that situations must be comprehensively analyzed in designing the main pipeline,that is,the study of pipeline should not only be made upon itself,but also made on the impact of interrelated technologies on the pipeline. The transfer capacity of the main pipeline,the reliability indexes of power equipments as well as the maintenance parameters are the prediction information of the reliability indexes in actual design. Still further,the analysis of oil pump station (compressor station) ,the specification and model of transfer equipment and the concrete connection way of transfer equipment have to be considered while the prediction information aforementioned are quantified to the specific design,and the concrete-ness and the accuracy of reliability indexes should be made for the equipments in each station if necessary. The calculations on the transfer capacity of pipeline and the several parameters have been made based on the current reliability indexes of the design adopted in Russia.
