摘 要: 为分析并阐述不同砾石粒径和不同布孔方式对砂砾岩储层水力压裂破裂压力的影响,进而为砂砾岩储层油气开采的布孔方式提供一定的理论依据,采用真三轴水力压裂实验系统,开展不同粒径砂砾岩储层人工物理模型在不同布孔方式下的三轴水力压裂实验。研究结果表明,砾石粒径显著影响水力压裂的破裂压力,随着砾石粒径的增大,破裂压力存在一个极限值;相对于线性布孔和对称布孔,螺旋布孔方式的破裂压力显著降低。
关 键 词: 固体力学;水力压裂;破裂压力;粒径大小;布孔方式

Abstract: In order to analyze and describe the influences of different particle sizes of gravel and different perforating methods on glutenite reservoir’s hydraulic fracturing fracture pressure, and to provide a theoretical basis for the perforating method on oil and gas exploitation of glutenite reservoir, tri-axial hydraulic fracturing test is conducted on artificial physical model of glutenite reservoir with different particle sizes under different perforating methods by true tri-axial hydraulic fracturing test system. Results show that the particle sizes of gravel can significantly influence the fracture pressure of hydraulic fracturing. As the gravel particle size increases, the fracture pressure will have a limit value; compared with the linear perforation and symmetrical perforation, the fracture pressure of spiral perforation decreases significantly.
Key words: solid mechanics; hydraulic fracturing; fracture pressure; particle size; perforating method
