摘要
巴彦呼舒凹陷是海拉尔盆地西南部的一个二级负向构造单元。在系统分析巴彦呼舒凹陷的石油地质条件后认为,凹陷内巴中次凹南屯组和大磨拐河组的泥岩是该凹陷的主要烃源岩。凹陷内广泛分布铜钵庙组、南屯组、大磨拐河组3套储集层,伊敏组泥岩是区域性盖层,大磨拐河组和南屯组泥岩是局部盖层。断块、断鼻和地层超覆等油藏类型较为发育,巴中次凹的鞍部隆起带和东部斜坡带是有利勘探区带。
This paper proposes some new opinions through analyzing the petroleum geology of Bayanhushu Sag. The claystones in Nantun Formation and Damoguaihe Formation in Central Bayanhushu Subdepression are main source rocks. The widespread Tongbaniao, Nantun and Damoguaihe sandstones are main reservoirs. Yinmin claystones are regional seals, while Damoguaihe and Tongboniao claystones are local seal. The faulted block reservoir, faulted nose reservoir and lithologic overlapping reservoir are the main reservoir types. The Saddle Uplift Region in central Bayanhushu Sag and the eastern ramp region are the favorable area of hydrocarbon exploration.
