Problems solved by technology
The use of ordinary cores for scientific research will lead to the following four problems: 1) invalid cores (due to stress release, the ground has been broken); 2) oil and gas reserves are estimated to be distorted, and the measurement is not accurate; 3) The life forms (microorganisms, viruses, etc.) that may exist in the deep rock formations die out; 4) The physical and mechanical parameters of the rock formations at different depths cannot be measured

The invention provides a fidelity coring device. The fidelity coring device comprises an outer cylinder and a fidelity cabin. The fidelity cabin is arranged in the hollow cavity of the outer cylinder,the outer cylinder is used for drilling a rock core, and the fidelity cabin is used for accommodating the rock core. A heater and a third liquid reservoir are arranged inside the outer cylinder, thedetected temperature of the rock core in the fidelity cabin is compared with the temperature at a coring position, the heater heats the fidelity cabin, or a coolant stored in the third liquid reservoir cools the fidelity cabin, so that the temperature in the fidelity cabin is maintained the same as that at the coring position. By arranging the fidelity cabin, the heater and the third liquid reservoir stored with the coolant are arranged in the outer cylinder, the detected temperature in the fidelity cabin is compared with the temperature at an original position of the coring position, the heater carries out heating or the coolant carries out cooling, so that the temperature in the fidelity cabin is the same as that at the coring position, and an insulation effect is achieved.
Description
technical field [0001] The invention belongs to the technical field of geological detection, and in particular relates to a fidelity coring device. Background technique [0002] At present, the "ordinary core" obtained by deep drilling at home and abroad has released components such as pressure, temperature, and pore water, which have been seriously distorted and have nothing to do with the deep in-situ environment. The use of ordinary cores for scientific research will lead to the following four problems: 1) invalid cores (due to stress release, the ground has been broken); 2) oil and gas reserves are estimated to be distorted, and the measurement is not accurate; 3) The life forms (microbes, viruses, etc.) that may exist in the deep rock formations die; 4) The physical and mechanical parameters of the rock formations at different depths cannot be measured. [0003] Among them, heat preservation is a major problem to be solved urgently. Contents of the invention [0004...
