摘要:
为研究取芯管取芯过程中压力与温度对损失瓦斯量的影响，以及t法的偏差，利用自主研发的取芯管取芯过程模拟测试装置，基于模拟试验的相似性，开展不同加热功率下取芯过程模拟试验与室温（30 ℃）对比，以及变温条件下不同吸附压力取芯过程模拟试验。结果表明：前30 min煤芯瓦斯解吸曲线符合Qt=a+b/［1+(t/t0)c］。吸附压力一定时，取芯过程模拟测试的煤芯瓦斯解吸率均大于室温下的对比测试，3~16 min（退钻过程）温度对损失量的影响大于0~3 min（取芯过程）；随着加热功率的增加，煤芯瓦斯解吸量增大，煤芯损失瓦斯量的模拟值亦增大；t法推算值与模拟值的绝对误差随加热功率的增大而增大，相对误差在65.08%~70.79%；加热功率一定时，随着吸附压力的增加，煤芯瓦斯解吸量愈大，煤芯损失瓦斯量t法推算值增大，模拟值亦增大；t法推算值与模拟值的绝对误差随吸附压力的增大而增大，相对误差在68.21%~72.13%。
Abstract:
In order to study the influence of pressure and temperature on the gas loss amount during the coring process of coring tube and the deviation of the t method,a self-developed simulation test device for the coring process of coring tube was used based on the similarity of simulation test.The simulation tests of coring process under different heating power were conducted and compared with the room temperature (30 ℃),and the simulation tests of coring process under different adsorption pressures with variable temperature conditions were also carried out.The results showed that the gas desorption curve of coal core in the first 30 min conformed to Qt=a+b/［1+(t/t0)c］ .When the adsorption pressure was constant,all the gas desorption rate of coal core in the simulation test of coring process were greater than that in the comparison test at room temperature,and the influence of temperature on the gas loss amount during 3~16 min (coring out process) was greater than that of 0~3 min (coring process).With the increase of heating power,the amount of gas desorption and the simulation value of gas loss amount in coal core increased.The absolute error between the calculated value of t method and the simulated value increased with the increase of heating power,and the relative error was 65.08%~70.79%.When the heating power was constant,with the increase of adsorption pressure,the calculated value of the gas desorption amount of coal core by t method increased,so did the simulation value.The absolute error between the calculated value of t method and the simulated value increased with the increase of adsorption pressure,and the relative error was 68.21%~72.13%.
