摘要

According to the study on components and its isotopes of natural gas in Yingnan-2 gas reservoir and the formation time, the paper discuss the genesis of Yingnan-2 gas reservoir, and reckon that it is a secondary gas pool formed by adjustment in the geologic history. The gas in Yingnan-2 gas pool is commixed by condensate gas, associated gas, kerogen cracking gas, and oil cracking gas. The condensate gas and associated gas are the main components and the key cause of high N₂ and fixed hydrocarbon contents.
