Method for determining filling property lower limit of tight sandstone gas

The invention relates to an oil and gas reservoir assessment method, in particular to a method for determining the filling property lower limit of tight sandstone gas. According to the method for determining the filling property lower limit, a nanoscale water film theory is introduced, on the basis of stress analysis of an adsorbed water film, and key parameters are determined in combination with targeted experiments. The critical filling state of natural gas can be simplified as the fact that when sandstone particles are arranged closely, the water film is in butt joint with blocking throats, and then the pores are effectively prevented from being filled with the natural gas through blocking, wherein at this time, the thickness of the water film equals the critical radius of the throats; if the radius of the throats is smaller than the thickness of the water film, corresponding pore throats and controlled tiny pores are saturated with bound water; only the throats of which the radius is larger than the thickness of the water film are the effective filling channels of the tight sandstone gas. Based on the method for determining the filling property lower limit of the tight sandstone gas, the property lower limit of tight reservoir exploiting can be accurately assessed, the exploration area of the tight sandstone gas can be enlarged, the reserves of the exploitable tight sandstone gas can be increased, and huge economic benefits are brought to oil fields.
