低渗煤层瓦斯抽采效率主控因素与一体化增效路径研究
摘要
Abstract
Low permeability is a core constraint for coal seam gas extraction in China.This study analyzes the coupling mechanism between geological conditions and engineering technologies,revealing that coal body structure is the decisive factor in technical selection options(hydraulic fracturing/hydraulic slotting).Research shows that the effectiveness of the project depends on its adaptability to geological attributes,and the kinetic rate of gas mass transfer from matrix to fracture is the key to improving production.Based on this,an integrated efficiency improvement path based on geological transparency evaluation,with differentiated technology adaptation as the core,with ″reducing the size of the matrix block″ as the focus,and combining intelligent management and control with full-cycle economic evaluation is proposed to provide systematic solutions for efficient gas extraction in low-permeability coal seams.关键词
