摘　　要：本文介绍了为研究井下泡沫水泥密度变化规律而专门设计的实验装置和实验结果。室内研究结果表明 ,泡沫水泥受井下温度和压力的影响 ,实际密度与地面密度相差较大 ,尤其是当温度大于5 0℃和压力小于 3MPa时 。This article introduces the specially designed experimental equipment and method to research into the variational regularity of foamed cement slurry d ensity in welldown. The lab studied results indicate that foamed cement slurry i s subjected to the effect of welldown temperature and pressure, and the actual d ensity is rather different from the lab density, and the effect is more obvious when temperature is more than 50℃ and pressure is less than 3 MPa.
