摘要
随着油气开发由陆地走向深海,海管输送已成为海上油气生产中主要的运输方式。深水环境温度低,原油析蜡问题一直是油气输送过程中不可避免的技术难题。采用新型多相流瞬态模拟软件LedaFlow对南海某油田输油管道的蜡沉积进行预测和模拟,得到不同年份蜡沉积厚度、管道沿程温度、流体温度和蜡含量的变化情况。根据模拟计算结果,分析海管内蜡沉积规律,为下一步除蜡和清管等操作提供建议,从而为工程实际提供参考。
With the development of oil and gas progressing from onshore to offshore deepwater, subsea pipeline transportation has become the main mode of transportation in offshore oil and gas production. Due to the low temperature in deepwater, wax deposition is an unavoidable technical issue in oil and gas transportation. The wax deposition of a subsea pipeline in the South China Sea was predicted and simulated using multiphase transient simulation software LedaFlow. The variations of wax deposition thickness, pipeline temperature, fluid temperature and wax content in different years were obtained. According to the simulation results, the wax deposition rule in the subsea pipeline is analyzed, to develop suggestions for the paraffin removal and pigging operation in the future, and providing reference for good engineering practice on this subject.
