Oil bath type temperature control fidelity coring device experiment platform

Abstract

The invention relates to an oil bath type temperature control fidelity coring device experiment platform, which comprises a box body, a temperature control system and a pressure experiment cabin. Thepressure experiment cabin is arranged in the box body, and the box body is provided with a liquid inlet, a liquid outlet and a first preformed hole. The temperature control system comprises a liquid supply system and an electric heater, an outlet of the liquid supply system is connected with an inlet of the electric heater, and an outlet of the electric heater is connected with a liquid inlet of the box. The pressure experiment cabin comprises a first test piece, a second test piece and a middle connecting piece. The first test piece is connected with the second test piece through the middle connecting piece, and a liquid injection hole is formed in the cylinder wall of the middle connecting piece. The high-temperature environment can be simulated, the pressure maintaining experiment cabincan be heated, the high-temperature environment can be provided for the pressure experiment cabin, an experiment is more complete and objective, and data is more reliable. The middle connecting pieceis used for connecting the test piece, so that drilling on the test piece can be avoided, the test piece is prevented from being damaged, and the experiment accuracy can be improved.

Description

technical field [0001] The invention relates to the technical field of a coring device test system, in particular to an oil-bath 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 properties of the core. The ...

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
