Abstract

Based on different gyromagnetic ratios, liquid state components are divided to A class and B class in order to form series of standard sample in different porosities. The method includes steps: solving relaxation agent C class to A class so as to constitute X fluid, and controlling concentration of C in 0.002%-2%; solving relaxation agent C class to B class so as to constitute Y fluid, and controlling concentration of C in 0.002%-2%; using digital titrator to distribute X fluid, and Y fluid to make total volume keep a constant value 0.1-20 milliliter, and control volume ratio between X fluid, and Y fluid being as 0.05% - 50% in order to form series of standard sample with porosities 1% - 36%. The invention provides accurate quantitative correction of porosity parameter for nuclear magnetic resonance apparatus.

Description

technical field [0001] The invention relates to a method for formulating a standard sample of a nuclear magnetic resonance rock sample analyzer, in particular to a method for preparing a nuclear magnetic resonance rock sample porosity standard sample, and belongs to the technical field of nuclear magnetic resonance physical property analysis signal calibration. Background technique [0002] The petroleum industry needs to analyze the physical properties of rock samples and provide parameters such as porosity and permeability of rock samples. [0003] The nuclear magnetic resonance instrument can measure the water content of the object, and the size of the nuclear magnetic resonance signal is proportional to the water content. After the rock sample is saturated with water, the internal pores are filled with water, and the nuclear magnetic resonance signal is corrected by the porosity standard sample, and the porosity parameters of the rock sample are calculated. [0004] The...
