摘要
应用轮式流动模拟器可以模拟多相混输管道的生产实际工况,通过监测流动模拟器转轮的扭距、转速、试验介质的温度、压力参数的变化,并结合直接观测的手段,综合进行水合物动态模拟试验。建立了水合物生成预测方法、水合物生长规律及动力学抑制效果试验研究方法,应用这些方法可以进行混输管道中的水合物生成条件预测试验、水合物热力学抑制效果试验及水合物动力学抑制效果试验,为混输管道的设计和正常生产运行提供技术依据。
The actual working conditions of a multiphase transmission pipeline can be simulated by wheeled flow simulators.The dynamic simulation of hydrates is comprehensively conducted by examining the torque,rate of revolution of the simulator wheels,temperature changes of the working medium as well as the changes of parameters in pressure with the help of direct observation.The method for predicting hydrates formation is established and the way to study hydrates' growing pattern and the effect of control by dynamics is found.With these methods,experiments on predicting the conditions for hydrates' formation and effects of control by dynamics or thermodynamics on hydrates in multiphase pipelines can be conducted,which lays a technical foundation for designs and normal operations of multiphase pipelines.
