措勤盆地沉积巨厚海相碎屑岩和碳酸盐岩,具备形成油气的物质基础,是重要的海相油气勘探区域。以实测地层剖面统计为基础,对中上侏罗统接奴群,下白垩统则弄群、多尼组、郎山组、捷嘎组及上白垩统竟柱山组作为盖层的宏观及微观特征进行了研究,探讨了地壳抬升、断裂活动、高原隆升与中生代油气保存的关系,初步认为伴随高原隆升构造运动对盆地油气保存的不利因素占主导地位。
The sedimentary thick marine clastic rocks and carbonate rocks in the Coqen Basin, with the material basis for oil and gas formation, are important marine oil and gas exploration areas. Based on the measured stratigraphic cross-section statistics, the macro and macro-correlations of the Upper-Middle Jurassic Conservatory, Lower Cretaceous Zeongnong Group, Duoni Formation, Langshan Formation, Jiegar Formation and Upper Cretaceous Jingzhushan Formation This paper studies the relations between crustal uplift, fault activity, uplift of the plateau and hydrocarbon preservation in the Mesozoic. It is preliminarily believed that the unfavorable factors of reservoiring with the uplift of the plateau dominates.
