摘要
通过突出煤层水力压裂的试验研究,逐步摸清低透气性煤层压裂所需的压力、流量等技术参数,进一步探测水力压裂有效半径,大大减少抽放钻孔工程量,降低工人劳动强度,最大限度地减少抽放时间,为采掘工序赢得工作时间,是本试验的初衷和追求的目标。
The goals of the test are acquisition the technical parameters, such as pressure and flow rate, etc. necessary for hydro-fracturing of coal seams with low permeability, further probing the effective radius of hydro-fracturing, reduction of the drilling volume to a great extent, lightening of labor intensity, reduction of drainage duration to the maximum for giving more time for coal mining.
