Abstract

The experimental investigation of gas permeation of sandy sediments during increasing of gradient pressure was carried out in the conditions before and after pore hydrate accumulation. The results show that there are permeability changes caused by gradient pressure increasing, due to various structural and texture transformations. The permeability increasing was noted by increasing of the differential pressure (more than 0.2 MPa) associated with the partial pore space destruction (gas fracturing) and the formation of micro-cracks. In the process of gas filtration through hydrate-bearing sediments the permeability is decreasing with increasing differential pressure, which may be due to additional hydrate formation processes in the porous media. Thus, experimental investigations that the gas filtration of gas through hydrate-saturated cores is accompanied by a number of physical and chemical processes that should be taken into account during methane production from gas and gas hydrate deposits.
