摘要： 从分析贺西地区板块发展演化入手,剖析了该区侏罗系的油气地质背景,指出印支末期该区形成的3个规模较大的沉降带具有形成油气田的地质条件。该区侏罗系烃源岩厚度较大,油气资源丰富,具有较好的油气储集与封盖条件,侏罗系是本区油气勘探的重要领域。最后预测了该区的油气勘探前景。

Abstract: Starting from an analysis of the plate-tectonic evolution of the area under study, this paper discuss-es the characteristics of petroleum geology of Jurassic in the area, and points out that the three subsidence belts formed at the end of Indosinian are geologically favorable for the formation of oil and gas fields. The Jurassic in this area developed thick and highly-po- tential source beds and good reservoir and sealing conditions, thus constituting an important target of exploration. On the basis of this work, the explo-ration potential of the area is predicted.
Key words: Hexi area, Subsidence belt, Jurassic, Ex-ploration potential
