摘要
泡沫是以液体为连续相,气体为分散相的均匀系统,是一种密度低、粘滞性较好、有压缩性的非牛顿流体。表面张力、溶液表面分子层的粘度、溶液粘度和温度对泡沫的稳定性有较大的影响。泡沫在石油开发的钻井、采油、排水以及泡沫冲砂洗井、泡沫水泥固井等方面均显示出优良的性能。
Foam is homogeneons system in that liquid is a continons phase and gas is a
dispersing phase. It is a Non -Newton fluid of low density, better viscosity and compressibility. The stability of foam is affected by sn rface tension. Snrface viscosity, liquid viscosity and temperature. Its excellent properties are showed in drilling, extracting, draining and so ou.
