江陵凹陷荆州背斜带为一继承性的古隆起带,含有丰富的油气资源,先后在下第三系新沟咀组下段、上段,荆沙组和潜江组发现工业油气流或油气显示,原油地化指标分析表明该区存在着两种成熟度不同的原油,即成熟原油和高成熟原油。油源对比研究表明,成熟原油来源于研究区新沟咀组下段成熟烃源岩,高成熟原油来源于与其毗邻的资福寺向斜带相同层位的高成熟源岩。
The Jingzhou anticline belt in Jiangling Depression is an inherited paleo-uplift belt, rich in oil and gas resources. Industrial oil and gas flow or oil and gas discovery was found in the lower section, upper section, Jingsha Formation and Qianjiang Formation of the Lower Tertiary Company. The crude oil Geochemical indicators analysis shows that there are two different mature crude oil in the district, that is, mature crude oil and high mature crude oil. The study of oil source shows that the mature oil comes from the mature source rocks in the lower part of the Xingouzui Formation in the study area, and the mature oil originates from the high maturity source rocks in the same layer as the adjacent Ziwuzhusi syncline.
