为研究煤层水力致裂的致裂机理和松动效果，开展了煤层不同钻孔水力致裂的对比数值研究，并结合现场试验进行了研究。在黑龙江省鸡西市城山煤矿现场试验的基础上，建立了单孔、三孔和五孔水力致裂模型，分析了水力致裂过程中钻孔周围水压力和剪应力的变化。讨论了控制井眼水力压裂对裂缝萌生和扩展的影响。现场测试结果表明，水力压裂中的井眼控制不仅可以控制裂缝的扩展方向，而且可以判断裂缝的萌生和破裂效果。本文的工作对水力压裂工艺设计和参数选择具有重要的理论和实践意义。
Comparative numerical study on hydraulic fracturing with various boreholes in coal seam combined with in situ experiments was carried out to investigate the fracturing mechanism and loosening effect of hydraulic fracturing in coal seam. Hydraulic fracturing models with single-borehole, three-borehole and fiveborehole were built based on in situ tests in Chengshan coalmine, Jixi city, Heilongjiang province, China and the changes of water pressure and shear stress around boreholes during hydraulic fracturing were analyzed. The influence of hydraulic fracturing with controlling borehole on crack initiation and propagation was discussed. According to the in situ testing results, it is found that controlling boreholes in hydraulic fracturing not only can control the direction of crack propagation, but also can judge the effect of crack initiation and breakdown. The work in this paper is of great importance for the design of hydraulic fracturing technology and the alternative of the parameters in theory and practice.
