Development Research Of Oil-water Two Phase Drag-reducing Simulation Experimental Device

During the past several years,with an increasing number of oilfields around the world entering into mid and late development period,the water cut in produced fluid is gradually increased,and the oil-water multiphase flow is frequently met in pipeline transportation.After the completion of the pipeline,the users demand and the oil viscosity are different in different seasons,it is difficult to reach an agreement on the actual throughput and design throughput.Especially in the mid and late development of the oilfields,the aging and loading capability of the pipe drop gradually,the user demand for oil products increased year by year instead,the diameter design is too small to meet the requirements of today's throughput.At present,the scholars around the world have made a large number of progress on two-phase flow,especially on the direction of gas-solid,liquid-solid and gas-liquid two phase flow,oil-water two phase drag-reducing is becoming an obstacle of oil-gas-water three phase drag-reducing research.In order to guarantee the pipeline throughput with a certain adjustment ability,it is significance to carry out the oil-water two phase drag-reducing research,and it is important to establish an oil-water drag-reducing simulation experimental device.With learning other loops' construction experience,this topic designs process flow of oil-water two phase drag-reducing simulation experimental device.According to the laboratory conditions,it plans the device layout,completes the calculation in the design of experimental apparatus,selects and purchases the corresponding power equipments and measuring instruments.After that,it completes the construction of the installation,calibration and two parallel pumps debugging work.In addition,it figures out experimental procedure of the device,carries out the verification experiment of the experimental device,summarizes some issues need to pay attention to in the process of experiment.This experiment device can complete oil single phase,water single phase and oil-water two phase flow and drag-reducing experiments.
