【摘要】：实验一直是一项重要的科学研究手段。而在多相流和多相蜡沉积这种前沿学科的研究中,建立多相流实验装置对其进行实验研究则显得更加重要。多相流实验装置是研究油气水多相流问题的重要手段,无论是在理论问题研究,还是在工程实际研究中,均占有重要的地位。针对克拉玛依工程教育油气储运工程实训基地和现场工程实际要求,设计研发一套多相流动的实验平台。根据设计要求和相关设计规范,充分考虑了实验装置的功能性和安全因素；确定实验装置的流程,绘制流程图和设备布置图；通过水力计算确定环道的流量、压力等参数,选择泵、仪表等实验仪器；根据计算结果,设计水罐、三相分离器、加热和保温装置等；主要设备及参数如下：采用不锈钢制环道,直管段长36m,4m长的转弯半径为25 D的弯管,两段4m长的有机玻璃制多相流观察段,用来观察流型。设计液相流速范围：0.2-1.5 m/s。气相流速范围：1.0～20.0 m/s。压力变送器测量精度为所选用量程的0.1%。DasyLab8.0采集软件采集包括压力、差压、流量、温度等参数。通过上述工作,实验装置能够实现含蜡原油管道蜡沉积、气液两相流动研究、多相流蜡沉积等实验功能。此外预留了可扩展的接口。在类似的环道进行了多相流和蜡沉积的实验,为本实验装置的调试和实验的进行提供了有力的技术支持。
[Abstract]:Experiments have been an important means of scientific research. But in the research of multiphase flow and multiphase wax deposition, It is more important to establish an experimental device for multiphase flow, which is an important means to study the problem of oil, gas and water multiphase flow, both in theory and in engineering practice. In order to meet the practical requirements of the training base and field engineering in Karamay engineering education, a set of experimental platform for multiphase flow is designed and developed. According to the design requirements and related design specifications, Fully considering the function and safety factors of the experimental device, determining the flow chart of the experimental device, drawing the flowchart and the layout diagram of the equipment, determining the flow rate and pressure of the loop by hydraulic calculation, selecting the experimental instruments such as the pump and the instrument, etc. According to the calculation results, the water tank, three-phase separator, heating and heat preservation device are designed. The main equipment and parameters are as follows: stainless steel annular passage, straight pipe section 36 m long turning radius 25D bend pipe, Two sections of 4m long polyphase flow observation section made of plexiglass, used to observe the flow pattern. Designed liquid flow velocity range: 0.2-1.5 m / s. Gas velocity range: 1.0 ~ 20.0 m / s. The 0.1%.DasyLab8.0 acquisition software for the selected range of measurement accuracy of the pressure transmitter includes pressure, differential pressure, flow rate. Temperature and other parameters. Through the above work, the experimental device can realize waxy crude oil pipeline wax deposition, gas-liquid two-phase flow research, Experiments on multiphase flow and wax deposition are carried out in similar annular channels, which provide powerful technical support for the debugging and experiment of this experimental device.
