The oil bath type internal and external temperature control fidelity coring device experimental platform comprises a box body, an external heating system and a pressure experimental cabin used for simulating a fidelity cabin of a fidelity coring device. The inner wall of the cabin body of the pressure experimental cabin is provided with an electric heating structure, and the cabin wall of the pressure experimental cabin is provided with a side hole. The pressure experimental cabin is arranged in the box body, the box body is provided with a liquid inlet and a liquid outlet, the external heating system comprises a liquid supply system and an electric heater, an outlet of the liquid supply system is connected with an inlet of an electric heater, and an outlet of the electric heater is connected with the liquid inlet through a liquid inlet pipeline. According to the experimental platform, a high-temperature environment can be simulated, the high-temperature environment can be provided for the pressure experimental cabin, a real in-situ environment can be achieved, an experiment is more complete and objective, and data is more reliable. Internal and external heating can be achieved simultaneously, the heating efficiency can be improved, the experiment time is easily shortened, and the experiment efficiency is improved. The internal electric heating structure is arranged on a pressurizing and heating intermediate piece, the structure of the pressure maintaining experimental cabin is not changed, and the experiment cost can be reduced.

Description

technical field [0001] The invention relates to the technical field of a coring device test system, in particular to an oil-bath-based internal and external temperature-controlled fidelity coring test platform. Background technique [0002] Mineral resources in the shallow part of the earth have been gradually exhausted, and marching into the deep part of the earth is an important direction for my country's scientific and technological innovation in the near future and in the future. The in-situ rock mechanical behavior of different deep host rock formations is the leading scientific and theoretical basis for deep drilling, deep resource development and utilization, and earth application science. [0003] The physical, mechanical, chemical and biological properties of deep rocks are closely related to their in-situ environmental conditions. The loss of in-situ environment during the coring process will lead to irreversible distortion of the physical, chemical and mechanical ...

AI Technical Summary

Problems solved by technology

The current pressure test platform can only perform pressure experiments, and the real in-situ environment is usually a high temperature environment. The existing pressure test platform cannot simulate a high temperature environment, and of course it is impossible to verify that the pressure holding chamber is in this high temperature environment. Under pressure performance

[0006] In addition, the existing pressure-holding test chamber is connected to the hydraulic pipeline by drilling holes on the wall of the cylinder. The drilling of the drilling rig will damage the pressure-holding test chamber, thereby making the experimental results unreliable
