摘要

摘要: 该文介绍了白音查干凹陷地质背景和构造格局,从典型油藏解剖入手,构建了不同结构类型的油气成藏模式,发现了4种类型的油气成藏模式:即断鼻型、断块型、岩性型和地层超覆型油气成藏模式。白音查干凹陷下白垩统巴彦花群发育3套烃源岩和2套储集岩,地化分析结果显示阿二段和腾格尔组烃源岩已进入生烃高峰阶段,为凹陷主要生油源岩;空间配置上烃源岩与储集岩平面相接、空间叠置,为油气运移成藏创造了良好的条件。通过综合分析油气富集的基本条件及油气藏分布的基本规律,认为发育于塔拉断层下降盘之上的近岸水下扇沉积储集体应作为油气勘探工作的重点。

Abstract: From the geological setting and structural situation of the Baiyinchagan Sag, through typical reservoir research, several different hydrocarbon accumulation patterns were built. Four of them were distinguished, namely fault-nose, fault block, lithologic type and onlap stratigraphic type. Three sets of source rock and two sets of reservoir were developed in the Bayanhua Group of the Lower Cretaceous in the Baiyinchagan Sag. Geochemical research shows that the main source rocks in the second member of the Aershan Formation and the Tenggeer Formation are already in hydrocarbon-generating peak. The source rocks and reservoirs are connected and superimposed, which provides perfect conditions for oil and gas migration. The fundamental condition of hydrocarbon accumulation and basic reservoir distribution were analyzed. The results suggest that nearshore subaqueous fans are the prior exploration field.
