摘要/Abstract

摘要： 为选择合适的封堵钻孔裂隙三相泡沫，通过对3种发泡剂、4种稳泡剂和3种不同粒径范围固相填充物的试验研究，得出了发泡倍数高、稳定时间长和携带固体物能力强的三相泡沫密封液材料配比，即：水溶液质量比0.4%的发泡剂FP-1、1%的稳泡剂WP-3和4%的粒径范围0.2~1 mm的混合固相填充物。现场应用试验表明，该材料配比的三相泡沫封堵测压钻孔裂隙，具有封孔时间短、测定过程快、测定值准确性高等特点，对提高瓦斯压力测定水平具有重要意义。

Abstract: In order to select suitable three-phase foam for sealing fracture around borehole,3 kinds of foam agents,4 kinds of stabilizing agents and 3 kinds of solid-phase filler with different particle diameter were studied.Three-phase foam sealing liquid proportion with high foamability,good stability and strong ability of carrying solid was obtained.The proportion is: 0.4 percent of foam agent FP-1,1 percent of stabilizing agent WP-3 and 4 percent of mixed solid-phase filler with 0.2 to 1 mm diameter.Practical application shows that this proportional three-phase foam has characteristics of little sealing borehole time,rapid determination process and high determination accuracy,which is meaningful for raising the level of gas determination.
