摘　　要：介绍了测定可循环泡沫钻井液动密度与压力、温度关系的方法,利用可循环泡沫钻井液动密度测定仪测量了不同温度、压力下可循环泡沫钻井液的动密度。结果表明,当温度一定时泡沫钻井液密度随压力增加而增加,泡沫钻井液动密度随温度的升高而降低,随压力的升高快速升高,大于一定压力后泡沫钻井液动密度随压力升高而缓慢变大,相同温度压力下静密度稍大于动密度。This paper presented a method to measure the relationship between dynamic density of foam drilling fluid circulating and temperature,pressure.By using the instrument foe measuring dynamic density of circulating foam drilling fluid,the dynamic density of foam drilling fluid at different temperature and pressure was measured.Results from experiments indicated that foam drilling fluid density declined with the temperature increase,enhanced quickly with pressure increase whether the temperature vary or not,increased slowly with pressure increase which is over certain value,but static density was higher dynamic density at same temperature and pressure.
