Reservoir properties under overburden pressure of Paleozoic in the middle area of Ordos Basin
Online published: 2011-12-20
The stress sensitivity of low permeability reservoir has great influence on the fluid flow capacity. The experimental study was carried out on the relationship between reservoir properties and overburden pressure of Paleozoic in the middle area of Ordos Basin. The result shows that the porosity and permeability become small with the increase of overburden pressure. The variation level and cause of reservoir properties in the low permeable sandstone and carbonate rock were analyzed, which has good effect to guide the exploitation and adjustment of oil and gas field.
Key words： carbonate rocks; fault; seismic curvature
