Embodiment Construction
[0017] The specific embodiments of the present invention will be described in detail below in conjunction with the technical solutions and accompanying drawings.
[0018] Such as figure 1 As shown, the working process is as follows: the core sample tube is filled with porous medium material, the liquid enters the core sample tube through the first constant temperature and pressure pump, and the outer tube of the core tube has a temperature-controlled liquid circulation to control the temperature of the core sample tube. The carbon dioxide gas enters the core sample tube through the second constant temperature and pressure pump. The liquid and carbon dioxide gas flowing out from the gas-liquid outlet of the core sample tube are measured by a balance and a flowmeter, and the working parameters such as temperature, pressure, mass and flow signals during the flow process are analyzed by a computer data acquisition system and real-time, nuclear magnetic resonance imaging The instr...

The invention relates to an in-porous-medium fluid temperature visualization measuring device, and belongs to the technical field of carbon dioxide sealing and storage. The in-porous-medium fluid temperature visualization measuring device is characterized by comprising a nuclear magnetic resonance system, an injection recovery system, a temperature and pressure control system and a computer data collection system. Carbon dioxide and fluid pass through a constant-temperature constant-pressure pump to enter a porous-medium sample in a rock core sample tube, carbon dioxide gas and fluid which flow out from the rock core sample tube pass through a counterbalance valve to enter the injection recovery system, circulation is carried out on the exterior of the rock core sample tube through a temperature-control fluid constant-temperature tank to conduct temperature control over the rock core sample tube, working parameters such as temperature signals and pressure signals in the measuring process are all collected and analyzed by the computer data collection system in real time, and the temperature visualization measuring is carried out on the whole gas-fluid injection process by a nuclear magnetic resonance imager. The in-porous-medium fluid temperature visualization measuring device has the advantages of being capable of rapidly and economically achieving temperature variation monitoring in the carbon dioxide sealing and storage process, obtaining the heat transfer coefficient in the sealing and storage process and improving the carbon dioxide sealing and storage efficiency.
Description
technical field [0001] The invention belongs to the technical field of carbon dioxide sequestration, and relates to a visual measurement device for fluid temperature in a porous medium. Background technique [0002] With the emission of global greenhouse gases, the global warming caused by the greenhouse effect has become the focus of world attention. The Intergovernmental Panel on Climate Change (IPCC) proposed Carbon Capture and Storage (CCS) technology to countries in 2005 to significantly reduce greenhouse gas emissions. Carbon dioxide sequestration is a powerful measure to reduce greenhouse gas emissions. At present, there are a variety of carbon dioxide storage technologies, mainly including geological storage, marine storage, industrial utilization and ore carbonization. CCS has been widely researched and widely used in countries all over the world. The measurement of formation water temperature in the process of carbon dioxide capture and storage has a very import...
