    摘要:

    针对渤海油田海底管道网络原始设计模型预测结果与投产后实际运行数据普遍存在差异的问题,为提高新油田开发时在役管道依托校核的可靠性和准确性,基于现场实际运行大数据,通过数据分析、噪点消除、归类总结和反演对比等方法,对混输管道水力计算模型进行适用性评估和改进。从油品性质、气液比、含水率等角度筛选3条有代表性的海底混输管道,以经过优化处理后的现场运行数据为基础,对比不同水力计算模型的压降计算误差,从而确定各类海底管道的推荐计算模型。推荐的水力模型和修正方法可为其他类似管道提供借鉴,用于海底混输管道输送能力的深入挖潜,为未来渤海油田新油气田的依托开发提供依据。

    Abstract:

    Aiming at the problem that the prediction results of the original design model of the submarine pipeline network in the Bohai Oilfield are generally different from the actual operation data after being put into production, in order to enhance the reliability and accuracy of verification of existing pipeline in the exploration study of new oilfield, analysis is carried out based on the field big data and the hydraulic simulation models of multiphase pipelines are analyzed and optimized after a series of data analysis, noise elimination, classification summary and inversion comparison. Considering aspects including oil properties, gas-liquid ratio and water cut, three pipes are used to conduct this study. These pipes represent different types, periods and oilfields. Based on the optimized on-site operation data, the recommended calculation models for different types of subsea pipelines are determined by comparing the pressure drop calculation errors of different hydraulic calculation models. The recommended hydraulic model and correction methods can provide reference for other similar pipelines, which can be used to deeply tap the transportation capacity of subsea multiphase pipelines and provide basis for the future development of new oil and gas fields in Bohai Oilfield.
