The presence of near-field fracture clusters plays a critical role in governing the mechanical behavior of fracture initiation during hydraulic fracturing processes. This study systematically investigates the mechanical properties and fracture propagation mechanisms in granite through uniaxial hydraulic fracturing tests, acoustic emission monitoring, and digital image scanning techniques. Statistical analysis of the experimental data shows that near-field fracture clusters induce significant reductions in fracture initiation pressure, acoustic emission activity, and energy dissipation, all of which follow an exponential decay pattern. When fracture density exceeds two cracks, the attenuation rate of the cracking pressure has decreased significantly, indicating a diminishing influence of fracture quantity on pressure reduction. Fracture surface morphology exhibits statistically significant variations under different fracture cluster configurations, with fractal dimension demonstrating a positive correlation with fracture density. The increasing complexity of fracture surfaces with higher fracture density is characterized by a negative linear relationship between fractal dimension and initiation pressure.

近场裂隙群的存在对水力压裂起裂力学行为的影响至关重要。通过单轴水力压裂试验、声发射监测及数字图像扫描技术,对花岗岩起裂过程中的力学与破裂特征进行研究。试验数据的统计学分析结果表明,近场裂隙群的存在显著降低了花岗岩的起裂压力、声发射振铃技术和能量,且呈现指数衰减规律。近场裂隙数量在达到双裂隙之后,起裂压力衰减速率显著降低,即裂隙数量的增加对起裂压力的影响弱化。破裂面几何分形维数在近场裂隙群的影响下,亦呈现统计意义上的显著差异,随着近场裂隙数量的增加,分形维数亦呈现增长特征,破裂面几何特征更为复杂,分形维数与起裂压力呈现负相关的线性关系。

近场裂隙群的存在对水力压裂起裂力学行为的影响至关重要。通过单轴水力压裂试验、声发射监测及数字图像扫描技术,对花岗岩起裂过程中的力学与破裂特征进行研究。试验数据的统计学分析结果表明,近场裂隙群的存在显著降低了花岗岩的起裂压力、声发射振铃技术和能量,且呈现指数衰减规律。近场裂隙数量在达到双裂隙之后,起裂压力衰减速率显著降低,即裂隙数量的增加对起裂压力的影响弱化。破裂面几何分形维数在近场裂隙群的影响下,亦呈现统计意义上的显著差异,随着近场裂隙数量的增加,分形维数亦呈现增长特征,破裂面几何特征更为复杂,分形维数与起裂压力呈现负相关的线性关系。

The presence of near-field fracture clusters plays a critical role in governing the mechanical behavior of fracture initiation during hydraulic fracturing processes. This study systematically investigates the mechanical properties and fracture propagation mechanisms in granite through uniaxial hydraulic fracturing tests, acoustic emission monitoring, and digital image scanning techniques. Statistical analysis of the experimental data shows that near-field fracture clusters induce significant reductions in fracture initiation pressure, acoustic emission activity, and energy dissipation, all of which follow an exponential decay pattern. When fracture density exceeds two cracks, the attenuation rate of the cracking pressure has decreased significantly, indicating a diminishing influence of fracture quantity on pressure reduction. Fracture surface morphology exhibits statistically significant variations under different fracture cluster configurations, with fractal dimension demonstrating a positive correlation with fracture density. The increasing complexity of fracture surfaces with higher fracture density is characterized by a negative linear relationship between fractal dimension and initiation pressure.
