摘要
In order to disclosure the enriched mechanism of the nature gas, this paper analyzed the origin of the nature gas in Feixianguan-Changxing Formations of Sichuan Basin, the hydrocarbon generating density of main resource rocks, the characteristics and the scales of the reservoirs, the conservation condition of the natural gas, the history of hydrocarbon generation and the adjusting process of the oil and gas reservoirs with the analyzed and examined data of resource rocks, the data of the cores and lamellas, and the data of the well logging and cutting logging, etc. Discussing the enrichment mechanism of natural gas is useful for finding the beneficial target areas in the Northeast Sichuan Basin when natural gas is explored.
