摘要:
为深入探讨煤层钻孔孔壁瓦斯涌出特征,通过孔壁瓦斯流量模拟测试及曲线拟合分析,获取了孔壁瓦斯静态、动态涌出规律。研究表明:由于"死空间"的阻碍作用,在孔壁瓦斯涌出瞬间,其静态瓦斯流量达到最大,此后随孔壁暴露时间的增加逐渐衰减至0;在煤层钻孔钻进过程中,孔壁动态瓦斯流量随钻进时间的延长而逐渐增大,停止钻进后将逐渐衰减至0。
Abstract:
In order to discuss further characteristic of gas emission from coalbed borehole wall, simulation test were carried out in laboratory, then test data was analyzed by using curve fitting toolbox, static and dynamic law of gas flow from borehole wall were acquired. Research results show that gas static flow from borehole wall achieves maximum value as soon as emission process begins because of dead space's hindrance function, then attenuates to zero gradually. During the course of drilling, gas dynamic flow from borehole wall increases continuously with the time of drilling increasing, and then attenuates to zero gradually as soon as drilling stopped.
