摘　　要：讨论了泡沫质量和气体压缩性对泡沫密度的影响 ,推导出了泡沫钻井液静液柱压力计算式 ,可以方便地估算泡沫钻井时的静液柱压力。同时分析了在常压地层进行泡沫或充气欠平衡压力钻井时所需的气液比。The factors influencing density of foams are discussed and calculating formula of hydrostatic pressure are derived, which can be easily used to evaluate hydrostatic pressure in foam drilling. Meanwhile, the gas-liquid ratio for foam drilling or gas-filled underbalanced drilling in normal pressure formations is analyzed.
