摘要
为研究鲁西某矿煤层注二氧化碳工程中,压力与断层面积对二氧化碳在煤体中运移规律的影响程度,借助Ansys-Fluent仿真软件,模拟研究6 MPa及12 MPa压力下,分别对含少量和大量断层的煤体注入二氧化碳的煤体的降温效果。研究结果表明:在断层达到一定面积和数量后,单位面积断层对煤体降温作用的影响减弱,其主要原因是过高的断层面积分散了注二氧化碳压力。
In order to study the influence of pressure and fault area on CO2 migration in coal seam of a coal mine in Western Shandong Province, the cooling effects of CO2 injection into coal seam with small and large faults under 6 MPa and 12 MPa pressures were simulated by Ansys-Fluent software. The results show that the influence of faults per unit area on coal temperature reduction is weakened after the faults reach a certain area and number. The main reason is that the excessive fault area disperses CO2 injection pressure.
