Abstract

The application provides an aperture measurement method, device, equipment and storage medium, the method obtains the T1-T2 pulse sequence of the sample to be detected and the D-T2 pulse sequence of the sample to be detected; according to the T1-T2 pulse sequence of the sample to be detected Measure the sample with the D-T2 pulse sequence of the sample to be tested, and obtain the T1-T2 signal and D-T2 signal of the sample to be tested; according to the preset inversion model, reverse the T1-T2 signal and D-T2 signal of the sample to be tested Determining the pore size and relaxation rate correlation spectrum of the sample to be detected, wherein the preset inversion model is determined according to the Bloch-Torrey correlation theory and the T1-T2 signal and D-T2 signal of the experimental sample; according to the correlation between the pore size and the relaxation rate Spectrum, determine the pore size and relaxation rate of the sample to be tested.

Description

technical field [0001] The invention relates to the technical field of petroleum exploration, and in particular, to a method, device, equipment and storage medium for pore size measurement. Background technique [0002] The pores of the rock are an important component of the structure of the petroleum reservoir, and the pores of the reservoir are one of the key factors affecting the physical properties of the rock. Therefore, it is necessary to accurately obtain the pore size of the rock pores in the process of petroleum exploration. [0003] The traditional method of measuring the pore size of rock pores usually considers that the relaxation time and the pore size are linearly related. The pore scale parameters are obtained by measuring the relaxation information and the linear relationship, and the pore size is obtained through this parameter. [0004] However, the existing technology can only be applied to conventional porous media in a fast diffusion state, and cannot be...
