Shale oil and gas resources are abundant in Songliao Basin, and shale reservoirs tend to have certain permeability anisotropy with different pore or laminar structures in different directions, and there is no experimental analysis of shale anisotropy and reservoir sensitivity. To solve this problem, this paper tests the shale permeability by pulse decay method, obtains the variation curve of permeability and effective stress, and analyzes the experimental data. The experimental results of permeability show that the permeability of shale in Songliao basin is basically 10-4mD, and the permeability parallel and perpendicular to the laminae shows strong anisotropy, and the permeability perpendicular to the laminae is about 3%-14% The permeability of different rock samples decreases exponentially with the increase of effective stress. It provides basic data support to ensure the development of shale oil in Songliao Basin.
