Description

technical field [0001] The invention belongs to the technical field of rock mechanical performance tests, in particular to a control system and method for rock mechanical performance tests under complex conditions. Background technique [0002] Mechanical properties of rocks refer to the mechanical properties of rocks under stress, such as elasticity, plasticity, elastoplasticity, rheology, brittleness, toughness, and heating; the stress-strain relationship, deformation conditions or rupture conditions of rocks with different properties, etc. all different. Due to the different components and structures of various rocks, the age of formation is different, and there are many cracks in them, resulting in great differences in their mechanical properties. , The difference is also very large, and this property is also affected by factors such as time, temperature, humidity, confining pressure, the way and speed of applying force, the history of deformation, and the surrounding m...

Problems solved by technology

[0004] The current measurement of rock density under high temperature and high pressure conditions is inaccurate; at the same time, the existing layering effect on large, thick, and monotonous shale intervals is poor, which is not conducive to rock exploration

[0005] In the prior art, the magnetometer of the tension sensor is easy to cause measurement errors during the working process, which improves the measurement accuracy of the tension sensor, which is not conducive to the accurate acquisition of rock tension data; the accuracy of measuring rock density in the prior art is low and cannot be guaranteed. Real and reliable rock density data, and the measurement efficiency is low; the corresponding matching cannot be effectively carried out in the existing technology, and the storage system is in a heterogeneous mode, resulting in long data cache time and reducing the accuracy of storage
