基于煤层气解吸和煤层试井等大量的实测数据，对黄陇煤田煤层的气含量、渗透率、储层压力和最小主应力等储层参数进行了研究。结果表明：黄陇煤田煤层气含量、渗透率较高；地应力较低；气含量、储层压力、最小主应力与煤层埋深呈正相关性；渗透率与最小主应力呈负相关性；渗透率与煤层埋深的关系不明显；最小主应力对储层压力影响明显。综合分析认为，煤层气含量和渗透率较高的彬长、焦坪矿区是煤层气开采最具有价值的区块。
基于煤層氣解吸和煤層試井等大量的實測數據，對黃隴煤田煤層的氣含量、滲透率、儲層壓力和最小主應力等儲層參數進行瞭研究。結果錶明：黃隴煤田煤層氣含量、滲透率較高；地應力較低；氣含量、儲層壓力、最小主應力與煤層埋深呈正相關性；滲透率與最小主應力呈負相關性；滲透率與煤層埋深的關繫不明顯；最小主應力對儲層壓力影響明顯。綜閤分析認為，煤層氣含量和滲透率較高的彬長、焦坪礦區是煤層氣開採最具有價值的區塊。

Based upon large amounts of measurement data of desorption and well test, studies of the reservoir pa-rameters such as the gas content, the permeability, the reservoir pressure, the minimum principal stress in Huan-gling-Longxian coalfield were conducted. The results show that the gas content and the permeability are relatively high, the ground stress is relatively low, the gas content, the reservoir pressure and the minimum principal stress are positively correlated to the burial depth of coal seams, the permeability and the minimum principal stress are nega-tively correlated, relationship between the permeability and the seam depth is not obvious, the influence of the minimum principal stress on the reservoir pressure is evident. From the integral analysis, it is considered that Binxian and Jiaoping mining area with relatively high CBM content and permeability are favorable block for CBM exploitation.
