Abstract:

 In order to study the elastic properties and complex resistivity of shale of Lower Cambrian Qiongzhusi Formation and Lower Silurian Longmaxi Formation in Sichuan Basin, crop samples were collected from southern Sichuan Basin,western Hubei and eastern Chongqing. Based on AutoScan-Ⅱ platform, planar scanning was conducted to shale samples to obtain the petrophysical parameters such as permeability and velocity. The result shows that the velocities of p-wave and S-wave are negatively correlated with permeability, and Young ’ s modulus and Poisson ’ s ratio are in line with shale standards, with strong compressibility. The values of four parameters of complex resistivity of shale in Longmaxi Formation decreased with the ascending of salinity in different degrees, but have less influence on dispersion curve. When the frequency is less than 10 kHz, phase angle and heterogeneous resistivity have a positive correlation with the slope of amplitude dispersion curve of complex resistivity. Through the comparison of dispersion property of different samples, it is considered that polarization effect of pyrite particles is the main factors for significant dispersion of heterogeneous resistivity and phase angle in Shizhu area of Chongqing. Because pyrite is the sign of rich organic matters, phase angle and hetero-geneous resistivity can be used as important indicators to detect target in Lower Silurian Longmaxi Formation.
