| 摘 要： | 在总结白音查干凹陷已探明油藏特征的基础上,从构造发育、构造样式、沉积和烃源岩特征等几个方面对油气成藏控制因素进行了分析,认识到该区油气富集平面上受生油洼陷的控制,在主生油洼陷周边,尤其在南坡和北坡富集;纵向主要分布在白垩系都红木组的都一段和腾格尔组,油气聚集受构造背景控制明显,主要聚集在大断层的两侧;鼻状构造、断块、断背斜为油气成藏的主要单元。

| Abstract: | Based on the characteristics of proven oil reservoirs in Baiyinchagan depression, analysis on the control factors of oil and gas reservoir-forming including tectonic evolution, structure style, sedimentary and source rock reveals the regularity of hydrocarbon enrichment, i.e. oil and gas reservoirs controlled horizontally by the main source sags distributes mainly in the periphery of hydrocarbon- generating sags, especially being enrichment in the southern and northern slopes ; in vertical ,oil and gas reservoirs distribute in the 1st member of Cretaceous Duhongmu Formation and Tenggaer Formation. Petroleum accumulation ,highly controlled by structure background, concentrated on the two sides of major faults.Structure noses, fault block and fault-anticlines are the main structure units to form oil and gas reservoirs. |
