摘要：

为了将岩石动载损伤的研究成果应用于爆炸增产技术优化设计和施工中,开展了激波作用下岩石相对损伤度与裂缝渗透率的定量关系研究。依据激波作用后试样的损伤实验结果,建立了激波掠过后试样的相对损伤度模型,并定义了无量纲弹性波速。依据无量纲弹性波速,求得了相对损伤度与裂缝孔隙度的定量关系。利用实验数据和理论模型,得到了裂缝孔隙度随裂缝渗透率的变化规律,并求得了裂缝的平均宽度。依据裂缝孔隙度,求得了相对损伤度与裂缝渗透率的定量关系。定性地对地层条件与实验条件下的渗流强化结果进行了对比,并预测了爆炸压裂技术在低渗透油藏的增产效果。

关键词: 激波, 相对损伤度, 裂缝渗透率, 裂缝孔隙度, 模拟实验, 低渗透油藏

Abstract:

The research achievements about rock dynamic damage were applied to the optimizing design and operation of the stimulation technology by exploding. The relationship between relative damage of rock and fracture permeability was investigated. On the basis of the damage experiment data of rock sample, the relative damage model of sample after exploding wave bypassing was deducted. The dimensionless elastic wave velocity was defined. Based on the dimensionless elastic wave velocity, the quantitative relationship between relative damage and fracture porosity was obtained. The experimental data and theoretical model were applied to study the change of fracture porosity with the fracture permeability. The average width of fractures was also gained. Based on the fracture porosity, the quantitative relationship between the rock relative damage and fracture permeability was achieved. The difference of permeability improvements under in-situ and experiment conditions was discussed. The stimulation result was forecasted by exploding method in low-permeability reservoir.

Key words: exploding wave, relative damage, fracture permeability, fracture porosity, simulation experiment, low-permeability reservoir
