Claim 0:
1. A method for acquiring an elastic modulus of a rock containing sedimentary rhythms, comprising:
acquiring a rock sample containing sedimentary rhythms;
measuring contents of rock elements in the rock sample at test points with an X-ray fluorescence (XRF) spectrometer, the test points being provided on different rhythms of the rock sample;
determining a lithology of the rock sample according to the contents of the rock elements;
determining an element-mineral relation equation according to the lithology;
determining mineral components of the rock sample with the lithology and the element-mineral relation equation;
determining a modulus coefficient of each of minerals according to the mineral components; and
determining an elastic modulus of the rock sample according to the mineral components and the modulus coefficient of each of the minerals.
