| 摘 要： | 通过对空气泡沫钻井流体用处理剂的优选，室内确定了阴离子型空气泡沫钻井流体的基础配方，对该泡沫流体性能进行了评价。结果表明，所研制的空气钻井泡沫流体具有良好的耐温性，耐温达90℃；良好的抗污染能力，耐NaCl量为6％，耐Ca^2＋浓度为500mg／L；较强的抑制性，能使泡沫在井壁形成保护膜，阻止水进入地层，有效防止井壁坍塌。并且，通过合理使用化学消泡剂，可达到泡沫基液循环利用的目的。

| Abstract: | An anion air foam drilling fluid was formulated in laboratory by optimizing additives. The performances of the fluid were evaluated. The fluid showed good heat stability and anti -pollution capacity, it was stable at 90 ℃, at 6% of NaCl or 500 mg/L of Ca^2＋. It formed protective foam layer on borehole wall, prevented water from entering stratum and borehole wall from collapsing. The drilling fluid could be recycled by using suitable chemical deforming agents. |
