Abstract
The Impact of Accurate Prediction of Natural Gas Compressibility Factor on the CO2 Replacement Method for Natural Gas Hydrate Exploitation
Highlights
Carbon capture, utilization, and storage (CCUS) is a new development trend of carbon capture and storage (CCS), which is a technology that captures and purifies the carbon dioxide (CO2) emitted during the production process and puts CO2 into a new process of production for recycling or storage
This study focuses on the combined technology of natural gas hydrate (NGH) extraction with CO2 replacement and ocean storage and points out that the impact of the prediction accuracy of the gas compressibility factor on the exploitation of NGH by the replacement with CO2
The combined technology of NGH extraction with CO2 replacement and ocean storage have enhanced the recovery of oil and gas at the same time by realizing geological sequestration of CO2 and achieved the goal of “integration of sequestration and utilization, emission reduction and benefit win-win."
Summary
Utilization, and storage (CCUS) is a new development trend of carbon capture and storage (CCS), which is a technology that captures and purifies the carbon dioxide (CO2) emitted during the production process and puts CO2 into a new process of production for recycling or storage. The Natural Gas Compressibility Factor capture industrial waste CO2 to mine NGH and achieve CO2 sequestration under the premise of ensuring the stability of the seabed reservoir This technology has improved the utilization of CO2 resource greatly and maximized the storage of CO2 by taking advantage of the huge potential of ocean storage space, which is a beneficial supplement to CCUS. The combined technology of CO2 replacement mining NGH and ocean storage has unique development advantages It can ensure the stability of the geological structure during the mining process, while storing the injected CO2 on the seabed for a long time, which expands the application scope of CCUS technology to a certain extent. With the continuous innovation and development of related technologies, this technology will definitely become the main force of NGH extraction technology in the future
