近距离煤层群钻采渗透率演化规律数值模拟研究
Numerical Study on Permeability Change Law Caused by Drilling in Close Coal Seam Group
【摘要】 采用COMSOL公司开发的多物理场直接耦合的高级仿真模拟软件系统研究了极薄煤层钻采对近距离煤层群卸压前后煤层渗透率变化规律的影响。现场应用实测结果表明了极薄煤层钻采卸压的可行性与适用性,同时也证明了数值模拟的正确性。
【Abstract】 The permeability of close coal seams before and after pressure relief caused by extra-thinl seam drilling was systematically researched with advanced simulation software COMSOL MULTIPHYSICS. Field test demonstrated that drilling extra-thin coal seam to relieve pressure was valid and applicable, and the simulating result was correct.
