页岩油是原油增储上产的重要领域。由于储层结构致密、超低渗透,页岩油工业开发需要对储层进行大规模压裂改造。与海相页岩储层相比,鄂尔多斯盆地长7_(3)陆相页岩油储层矿物成分与岩石组构差异较大,力学非均质性较强。陆相页岩油靶层选取和高效压裂改造需要明确页岩力学行为和水力裂缝扩展规律。对长7_(3)陆相页岩进行了原位X-ray CT力学试验和三轴水力压裂试验。分析了岩石组构、地应力差和流体黏度对水力裂缝垂向扩展的影响规律。结果表明,岩石组构对陆相页岩的力学行为和破坏过程有显著影响。陆相页岩水力裂缝的垂向扩展受垂向应力差和流体黏度的共同控制。当垂向应力差较小时,黑色页岩中原生弱面显著抑制了水力裂缝的垂向扩展。随着垂向应力差的增大,黑色页岩裂缝体积呈线性增加趋势,而纹层型页岩裂缝体积呈先增大后减小趋势。增大压裂液黏度可减弱层面的阻碍作用,促进水力裂缝垂向扩展。

Diffusion is an important mass transfer mode of tight sandstone gas. Since nano-pores are extensively developed in the interior of tight sandstone, a considerable body of research indicates that the type of diffusion is mainly molecular diffusion based on Fick＇s law. However, accurate modeling and understanding the physics of gas transport phenomena in nanoporous media is still a challenge for researchers and traditional investigation（analytical and experimental methods） have many limitations in studying the generic behavior. In this paper, we used Nano-CT to observe the pore structures of samples of the tight sandstone of western of Sichuan. Combined with advanced image processing technology, threedimensional distributions of the nanometer-sized pores were reconstructed and a tight sandstone digital core model was built, as well the pore structure parameters were analyzed quantitatively. Based on the digital core model, the diffusion process of methane molecules from a higher concentration area to a lower concentration area was simulated by a finite volume method. Finally, the reservoir＇s concentration evolution was visualized and the intrinsic molecular diffusivity tensor which reflects the diffusion capabilities of this rock was calculated. Through comparisons, we found that our calculated result was in good agreement with other empirical results. This study provides a new research method for tight sandstone digital rock physics. It is a foundation for future tight sandstone gas percolation theory and numerical simulation research.
