Abstract

The invention relates to a high-pressure and high-temperature simulation experiment system for a fidelity coring device. The system comprises a pressure supply unit, a heat source supply unit, a high-temperature and high-pressure cabin, a data acquisition unit and a control unit. The high-temperature and high-pressure cabin comprises a temperature box and a pressure experiment cabin arranged in the temperature box, and the temperature box is provided with a medium inlet, a medium outlet and a first preformed hole for an experiment pipeline to penetrate through. The pressure supply unit is connected with the pressure experiment cabin through a pipeline so as to adjust the pressure in the pressure cabin. The heat source supply unit is connected with the incubator through a pipeline to adjustthe temperature of the pressure experiment cabin, and the pressure supply unit, the heat source supply unit and the data acquisition unit are all connected with the control unit. The pressure supplyunit and the heat source supply unit are arranged, the high-temperature and high-pressure environment can be simulated, the pressure maintaining capacity of the pressure maintaining experiment cabin under the high-temperature and high-pressure conditions can be verified, the experiment integrity can be improved, the defects of the fidelity cabin of the coring device can be better found, and therefore the fidelity cabin of the coring device can be better improved.

Description

technical field

[0001] The invention relates to the technical field of coring experiment devices, in particular to a high-pressure and high-temperature simulation experiment system for a fidelity coring device. Background technique

[0002] 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 core and key of the research is How to obtain in-situ cores under deep environmental conditions, and perform real-time loading tests and analysis under in-situ fidelity.

[0003] After the drilling rig obtains the sample, it needs the pressure maintaining control device of the fidelity chamber to maintain the pressure and seal the sample. The pressure-holding performance of the fidelity chamber needs to be continuously verified and improved ...
