Abstract

Clay is the important factors influencing the permeability of sandstone. Studying the permeability of different clay content in sandstone is of great significance to the safety and effectiveness of the engineering. Due to the complexity and lithologic differences of natural rock composition，the effect that proportioning of clay may have on gas permeation flow behavior in loose manufactured clayey sandstones was studied during the applying and relieving of confining pressure. Make some artificial rock samples with different clay-quartz sand proportions. The artificial aggregate was quartz sand of a size between 70–140(sieve opening，the number of sieve meshes per inch) and the clay was montmorillonite and illite. A gas permeation flow test including an application and a relieving stage of confining pressure was conducted on a TOP testing machine using the same stress path. The test permeation gas was nitrogen. The permeation pressure was 1 MPa，the axial pressure 1 MPa；and the applying and relieving path of the confining pressure was 4，6，8，10，12，15，12，10，8，6，and 4 MPa. The regular of gas permeability variation as a function of confining pressure and the mechanical property in artificial rock samples，made of different clay contents，was found. Combining with the Darcy¢s law and Poiseuille penetration model，the permeability-confining pressure model that based on artificial stone with different clay content was built. The findings suggest that in term of article sample rocks both clay content or porosity and initial permeability satisfy Boltzmann function. The stress-strain relationship can be regarded as linear model when the clay content is low. And can be regarded as nonlinear model when clay content is high. The permeability-confining pressure relation changes from a power law relation to a negative exponential one as clay content increases. Compaction of confining pressure can make the stress-strain relationship change to the linear model. Characterized by permeability-confining pressure changes from the negative exponent relationship to power law relationship，higher the clay content in the sample，reduces the strength of the internal structure. Transfixion cracks are easier to produce under stress and increase permeability.

Key words： rock mechanics artificial sandstone clay proportion loading-unloading confining pressure seepage experiment permeability model
