摘　　要：采用降压法研究原油的性质、温度、原油含水量、溶解气体的类型对原油起泡性及其稳定性的影响。结果表明:原油中的胶质沥青质质量分数越高、黏度越大,其泡沫的稳定性越大,消泡速率越小;原油的泡沫体积随温度升高呈先升后降趋势,消泡速率随温度提高而增大;模拟气、CO_(2)和N_(2)具有不同趋势的泡沫衰减曲线;气体在原油中的溶解度越小,泡沫的稳定时间越长,且原油的黏度越高泡沫出现峰值的时间越晚,峰值维持时间越长。The effects of the properties of crude oil,temperature,water content,and type of dissolved gas on the foaming properties and stability of crude oil were studied.The results show that the higher the resins and asphaltenes content and viscosity of the crude oil,the greater the stability of the foam and the smaller the defoaming rate.The volume of crude oil foam rises first and then decreases with the rise of temperature,while the defoaming rate increases with the increase of temperature.The foam decay curves of simulated gas,CO_(2) and N_(2) present different trends.The smaller the solubility of the gas in crude oil,the longer the foam stability time.And the higher the viscosity of crude oil,the later the foam peak time and the longer the peak time.
