Abstract: The permeability of the shale reservoir is nanoDarcy. After fracturing the fractures that appear in the shale reservoir are very complex, which can’t be described by conventional method. The conventional flow instrument for the fractures is improved. A more applicable flow chamber is remade to evaluate the flow conductivity of the network-like fractures more accurately. The model of the network-like fractures includes the marble and high-intensity proppants.

Abstract: Sulfonated-polyethersulfone/TiO2 (SPES/TiO2) nanoparticle composites with different TiO2 content were prepared by a sol-gel process. These composites have nanosized TiO2 rich domains well dispersed within SPES matrix observed by SEM photograph. The effect of TiO2 nanoparticles on the hydrophilicity of SPES was discussed by contact angle goniometer. The mechanism of the hydrophilicity improvement of these composites was analyzed by the molecular interaction theory and FT-IR. The hydrogen bond and coordination bond between SPES and TiO2 nanoparticle were observed. Comparing with the pure SPES, the SPES/TiO2 composites exhibited an outstanding increase in hydrophilicity.
