After more than 10 years of research and research, the Jilin Oilfield has formed an integrated carbon dioxide storage monitoring method of "soil carbon flux + carbon isotope + shallow wells". The field has carried out more than 200 multi-directional monitoring of the atmosphere, surface, and shallow layers in the test area. As of now, no carbon dioxide leakage has been found, and the storage effect is good.
Jilin Oilfield is an important demonstration unit of the Group's carbon dioxide flooding and storage project. It has an annual storage capacity of more than 350,000 tons, and has accumulated more than 2 million tons of carbon dioxide. Due to the special physical properties of carbon dioxide, there are high requirements for the wellbore and reservoir, and there is a risk of leakage during the process of injection and storage. The self-developed integrated storage monitoring method can establish a storage monitoring system for different landforms and seasonal changes to effectively monitor and evaluate the storage of atmospheric, surface and shallow carbon dioxide.
At the same time, in order to achieve fixed-point, continuous, quantitative, and intelligent monitoring, Jilin Oilfield will gradually explore technologies such as vorticity micro-meteorological monitoring, remote sensing and telemetry imaging, and infrared spectroscopy monitoring based on the characteristics of the carbon dioxide flooding test area and the construction of the Internet of Things, so as to expand the mine field. The application lays the foundation to help storage and monitoring technology gradually move towards industrialization and efficiency.
