| 摘 要： | 论述了安徽宿东矿区受层滑构造而引起的煤层破碎、揉皱或塑性流动可导致煤储层的孔裂隙、渗透性及吸附能力等一系列的变化。在构造破坏程度低的区域,煤储层裂隙发育,有利于煤层气的抽排;煤层构造破坏程度较高的地区,煤层发生揉皱变形,煤储层的渗透率降低,因此不利于煤层甲烷的抽排。

| Abstract: | This article discusses that the crash-up or plasticity flowage of coalbed brought by interlayer-gliding structure can result a series of change of coal reservoir in the porosity, fracture, permeability and absorption. In the area of the low-breakage degree, the coal reservoir has a lot of fracture, which is propitious to the extraction of coal methane; in the area of the high-breakage degree, the permeability of the coal reservoir is always very low, so the coal methane is difficult to bump. |
