【摘要】 基于淮南潘谢深部区块内部及外围的煤层气/瓦斯含量、镜质组反射率等实测资料、钻孔剖面测温成果,结合等温吸附实验,分析了研究区煤级梯度及现代地温梯度,探讨了深部煤层含气量与煤级、压力的正效应、与温度的负效应关系。在上述研究的基础上,根据煤级、压力、温度条件,采用正、负效应综合法,对区块深部煤层含气量进行了预测,并探讨了13-1煤层的含气量分布特征。更多还原

【Abstract】 Based on the test data of CBM & CMM contents and vitrinite reflectance,the temper- ature-measured results of coal holes and the results of isothermal adsorption experiments from deep coalbeds of Panxie area and the surrounding areas Huainan coalfield,coal rank and modern geo- thermal gradient of the studied region were analyzed.The relations of CBM content of deep coal- beds vs coal rank and pressure(plus effect)as well as temperature(minus effect)were dis- cussed.On the basis of the above research,CBM content of deep coalbeds was predicted by means of synthetical method of plus and minus effect in the light of coal rank,pressure and tem- perature.Finally,distribution characteristic of CBM content of the No.13-1 coal seam was dis- cussed.更多还原
