Abstract
A method for correcting measurement values of physical properties of laumontite-rich clastic rock reservoirs that are obtained based on overburden pressure porosity and permeability tests. The method includes: selecting rock samples taken from laumontite-rich clastic rock reservoir spaces; conducting porosity and permeability tests on the selected rock samples under normal temperature and pressure conditions; analyzing a type of a reservoir cement and characteristics of a reservoir space by using a respective selected rock sample; determining laumontite contents and development degrees of pseudo fractures in the selected rock samples having different laumontite contents; comparing variations in porosity and permeability between the selected rock samples taken from the laumontite-containing reservoir spaces and rock samples taken from a laumontite-free reservoir space under overburden pressure conditions; fitting a variation function to establish relations between the porosity, permeability, and overburden pressure for the selected rock samples taken from laumontite-rich clastic rock reservoir spaces; and creating a correction plate of permeability of reservoirs having different laumontite contents.
