煤层气解堵的实验研究 -

利用添加表面活性剂降低煤粉和水的表面张力,使煤粉容易被水润湿。浆体具有一定的流动性,从而可被活性水从煤层细缝中冲去达到解堵的目的。通过对不同表面活性剂的解堵作用效果的研究表明:加入自制表面活性剂PS后,煤粉和水之间的表面张力明显减小,对煤层气有较好的解堵效果,实现煤层气的增产。 The surfactant could reduce the tension between the coal and the water molecule,the particles of coal are easy to be moistened by water. The fluid slurry could take the particles of the coal plugged up the slit of the coal bed to gain the ends of blockage remover. The results of the research the effect of the different kinds of surfactants show that: PS could reduce the tension obviously, and remove the particles of the coal efficiently to increase the quantity of coal-bed gas
