Abstract
A system and method for exploiting deepwater shallow low-abundance unconventional natural gas by artificial enrichment is provided. The system includes a metallogenic system, a transport system and a collection system. The metallogenic system is used for clustering and enriching the deepwater shallow low-abundance nonconventional natural gas to form a natural gas hydrate reservoir. The metallogenic system includes an artificial foundation pit and a dome cap covering the top of the artificial foundation pit. The transport system is used for transporting low-abundance natural gas in a deepwater shallow low-abundance nonconventional natural gas stratum to the metallogenic system to provide a gas source for synthesizing the natural gas hydrate reservoir for the metallogenic system. The transport system includes oriented communication wells connecting the artificial foundation pit and the deepwater shallow low-abundance nonconventional natural gas stratum and filled with gravel particles. The collection system is used for exploiting the natural gas hydrate reservoir.
