Fracture network hydrothermal transfer visual tracing experiment system

Abstract

The invention discloses a fracture network hydrothermal transfer visual tracing experiment system, and belongs to the technical field of geoscience experiments. The system comprises a water supply device, a fracture model, a seepage process monitoring device, a heat transfer process monitoring device, a terminal control system, a wellhead monitoring device and a pipeline system. The water supply device is connected with the fracture model through the pipeline system. The fracture model is a fracture network physical model printed by a digital light processing 3D printer. The seepage process monitoring device, the heat transfer process monitoring device and the wellhead monitoring device are all connected with the terminal control system, and transmit collected data to the terminal control system for analyzing and processing. The internal seepage law and wellhead response characteristics of a fracture network under different temperature and flow conditions can be systematically studied. Meanwhile, the seepage and heat transfer process in a fracture can be directly observed, and a new tool is provided for analyzing the fracture structure and parameters according to the ground response of a wellhead and the like and understanding the hydrothermal transfer rule in the fracture.

Description

technical field [0001] The invention belongs to the technical field of geoscience experiments, and in particular relates to a visual tracing experiment system for water and heat transfer in a fracture network. Background technique [0002] With the increase of people's exploration and development depth of geological resources, the type of reservoir medium has changed from porous to structural fractures or artificial fractures; understanding the seepage and heat transfer process of deep reservoir fractures is very important for the sustainable development of deep geological resources . However, the fracture structure of the reservoir is complex, and it is invisible when it is buried deep underground. The research on the water and heat transfer process and the main controlling factors inside the fracture is still a hot and difficult research point in the field of geosciences. [0003] At present, the analysis of water and heat transfer process in complex fractures mainly reli...

AI Technical Summary

Problems solved by technology

[0008] In summary, there is still a lack of a fracture model that can describe the spatial combination of complex fractures and control the internal microstructure of fractures; when simulating the seepage process, some experimental systems have achieved transparent visualization; but when simulating the water heat transfer process, Experiments are currently only carried out under non-transparent black box conditions
