The present invention provides a multifunctional rock mechanics tester, pertaining to the technical field of mechanics tester, consisting of a base; wherein a power mechanism is mounted on the top of the base, two tension testing mechanisms are arranged on the power mechanism in an up-and-down symmetrical way, a clamping mechanism is mounted on each tension testing mechanism, a rock testing block is clamped between the two clamping mechanisms. The present invention realizes the tension and pressure testing of the rock test block through the arrangement of tension testing mechanism and pressure testing mechanism, thus improving the functionality of the present mechanics tester, which not only reduces the testing cost, but also effectively decreases the occupied space; the present invention solves the problem that the traditional mechanics tester can only complete one kind of test when it is used.

Multifunctional rock mechanics tester

The present disclosure discloses a classification method and system for fine-grained mixed sedimentary rocks, a medium and a terminal. Core description and thin section observation are used to accurately identify the sedimentary structure types and their vertical distribution characteristics from the macroscopic and microscopic perspectives, and indicates the mixed sedimentation characteristics of combination of different lamina or laminar couplets. The micro-drilling sampling technique is used to sample the samples with different types of sedimentary structures while avoiding diagenetic minerals. X-ray diffraction mineral content analysis and a high-precision carbon-sulfur analyzer are used to obtain the contents of different types of minerals and the total organic carbon contents in each sample, respectively, the basic rock type of each sample was determined using a triangular classification diagram. The name of sedimentary structure and the total organic carbon content are added in order before the name of the basic rock type.
