莺黄组浅层常压气藏的烃源问题，是本区天然气勘探及石油地质研究中所必须搞清的重大问题之一。本文在已获地质地球化学资料的基础上，对其烃源及成藏富集条件进行了深入剖析和研究，进而综合判识和确认浅层常压气藏的烃源主要来自莺黄组中下部生烃岩。
The hydrocarbon source of the shallow atmospheric reservoirs in Yinghuang Formation is one of the major issues that must be figured out in the research of natural gas exploration and petroleum geology in this area. Based on the geological geochemistry data, this paper deeply analyzes and studies the hydrocarbon source and the condition of hydrocarbon accumulation and accumulation, and then the hydrocarbon sources of shallow atmospheric reservoirs are identified and identified mainly from the middle and lower reaches of Ying-yang Formation Hydrocarbon rocks.
