用转轮流动模拟器测定集油温度下限

Application of Turning Wheel Flowing Simulator in Determination of Oil-gathering Temperature Limits

用转轮流动模拟器测定投加化学剂和不投加化学剂时集油温度下限是可行的。结合油珠聚结温度测试数据对转轮流动模拟器试验数据进行了分析和解释。试验结果表明，用转轮流动模拟器可以精确方便地测定集油温度界限，可同时得到摩擦因子、水包油型原油乳状液油珠聚结温度和凝油粘壁温度等数据。用转轮流动模拟器获得的试验数据进一步证实了水包油型原油乳状液油珠聚结温度的概念。

Test result shows that oil-gathering temperature limits can be determined accurately and conveniently by using turning wheel flowing simulaton, at the sametime the data of friction factor, coalescing temperature of oil drop of oil- inwater type crude emulsion and the temperature condensing oil sticking to the pipe's wall etc. The data got from the test of turning wheel flowing simulator further confirms the concept of coalescing temperature of oil drop of oil-in- water type crude emulsion.
