Method for continuously characterizing microscopic pore throat parameters of reservoir based on high-pressure mercury injection analysis
2014
The invention relates to the field of exploration and development of petroleum and natural gas and in particular relates to a method for continuously characterizing microscopic pore throat parameters of a reservoir based on high-pressure mercury injection analysis. On the basis of the high-pressure mercury injection, a method for quantitatively characterizing the microscopic pore throat structure parameters by using macroscopic physical parameters of the reservoir is established. The method has the advantage that as long as the macroscopic physical parameters and deposition micro phases of one reservoir are known, the method can be used for determining distribution characteristics of the microscopic pore throat structure parameters of the reservoir and continuously characterizing the distribution characteristics of the microscopic pore throat structure parameters of the reservoir.
