摘要
为提高煤层开采水平,通过分析地应力、埋深、煤储层压力等对渗透率的影响,分别构建煤储层渗透率与其影响因素之间的拟合关系,利用定量关系对潘庄井田煤储层的渗透率进行了系统预测.预测结果显示：潘庄井田上主煤层3煤的渗透率大约在0.3×10^-3～2.1×10^-3μm^2,下主煤层15煤的渗透率大约在0.4×10^-3～0.8×10^-3μm^2.
Through analysing impacts of crustal stress, deep burying, and the coal stores on penetrance as one layer of pressures , etc, the paper introduces the formation of the relation of fitting between one layer of penetrance and its influence factor separatel relation store to systematic prediction of Panzhuang well y, and the use of above - mentioned quantitative coal penetrance of layer. The farmland in Panzhuang well 3 coals shows permeating rate of the 0.3 × 10^-3 -2.1 × 10^-3 μm^2 up the main coal seam. Descend main coal seam 15 coals gives the permeating rate of the 0.4 × 10^-3 -0.8 × 10^-3 μm^2.
