Description
Technical Field
The invention relates to the technical field of tunnel engineering, in particular to a deep coring high-temperature high-pressure analog test cabin.
Background
At present, mineral resources in the shallow part of the earth are gradually exhausted, the resource development is continuously carried out towards the deep part of the earth, the coal exploitation depth is 1500m, the geothermal exploitation depth is over 3000m, the metal ore exploitation depth is over 4350m, the oil gas resource exploitation depth is 7500m, and the deep resource exploitation is normal. Deep rock is always in a high temperature environment, and is quite different from surface rock. The temperature is an important factor affecting properties such as rock mechanics, wherein coal resource exploitation activities gradually developing to deep parts are affected by the temperature, so that many scholars have studied about the influence of the temperature on the properties of the coal and the rock mechanics, gas adsorption analysis, seepage rules and the like. In the aspect of coal physical properties, the existing researches show that the strength of coal is reduced along with the temperature rise; study on gas adsorption/desorption, and related scholars consider that the adsorption capacity of coal is reduced along with the increase of temperature; the relation between the seepage flow of the gas in the coal body and the temperature is complex, and the academic world has not formed unified knowledge. It can be seen that as the temperature increases, the mechanical properties of the coal and rock, gas adsorption analysis, seepage rules and the like are changed, and the properties of the rock at normal temperature are regarded as the properties of the deep rock, so that great deviation is brought to engineering, and therefore the temperature is particularly important as one of in-situ occurrence environments of the deep rock. Scientific drilling is an indispensable important means for solving important problems of resources, disasters, environment and the like faced by human beings, but the traditional large Liu Shen field of drilling core cannot preserve heat, so that the in-situ core mechanical behavior rule, gas phase information and the like cannot be completely and scientifically obtained due to the distortion of the core temperature, and therefore, deep rock in-situ heat preservation coring technical equipment must be developed to realize fidelity of rock temperature under deep in-situ environmental conditions, and a foundation is provided for subsequent test analysis.
At present, in the field of drilling and coring in the large Liu Shen area, the main focus is still on the coring drilling technology, only the marine drilling field has been focused on the submarine sediment fidelity sampling technology, but the marine corer is mainly designed for pressure maintaining coring, most of the marine corer does not adopt heat preservation measures, but when the corer reaches the ground, the core is put into a specially designed device, and the heat preservation purpose is realized by adopting measures such as quick icing or liquid nitrogen freezing, such as a DAPC (DAPC) corer and a MAC (media access control) corer; only a few coring devices for submarine sediments relate to the heat preservation technology, the heat preservation measures of the coring devices are passive heat preservation (reducing the heat dissipation capacity of the core), no active heat preservation measures (constant control temperature) are adopted, and finally the temperature of the core can still be reduced. In addition, quite different from the field of thermal insulation coring of submarine sediments, the land deep rock stratum is often in a high-temperature state, and the purpose of the thermal insulation coring technology is to prevent the temperature of the rock core from being reduced, so that the existing thermal insulation technology cannot be directly applied to thermal insulation coring of the deep rock stratum, and the thermal insulation coring technology of the rock stratum still needs to be further explored.
In the indoor test process which is developed by taking active heat preservation and passive heat preservation as research ideas, a test platform for simulating the in-situ high-temperature high-pressure coring device is needed to simulate and test the effect of the coring device.
