AI Technical Summary
Technical Problem
The existing carbon dioxide sequestration cap grouting test device cannot effectively observe whether the cracks are completely filled with grout, which affects the evaluation of the cap's airtightness.
Method used
An IoT-based sealing cap grouting carbon dioxide test device was adopted, which combines a data acquisition system and IoT technology. The crack filling was monitored by stress-strain sensors and ultrasonic sensors, and a three-dimensional model was generated for visualization observation.
Benefits of technology
It enables precise evaluation of the grouting and sealing effect of the caprock, enhances the safety and stability of carbon dioxide geological sequestration, and ensures the long-term sequestration of CO2.

Abstract
The present application belongs to the technical field of carbon dioxide geological storage, and particularly relates to a test device and method for sealing caprock grouting plugging carbon dioxide based on the Internet of Things, which comprises a high-pressure-resistant closed chamber, a closed reaction kettle, a grouting system, a carbon dioxide injection system, a pressure stabilizing system and a data acquisition system; the closed reaction kettle is arranged in the high-pressure-resistant closed chamber; the closed reaction kettle is internally provided with reservoir rocks in a saltwater-saturated state; caprock is arranged on the reservoir rocks; the caprock has developed fissures; the data acquisition system is used to acquire the stress-strain change value of the caprock before and after grouting, the temperature data of the caprock, the pressure change data and the filling condition of the fissures in the caprock. The experimental device can be used to explore the influence of caprock grouting on the sealing property of the carbon dioxide geological storage caprock, and provides an experimental basis for grouting treatment of the caprock with developed fissures and poor sealing property in the carbon dioxide geological storage.
