| 摘 要： | 研究了巴彦浩特盆地石炭系的沉积类型及特征,探讨了石炭系不同阶段的沉积演化。巴彦浩特盆地石炭系发育泻湖-潮坪、三角洲-扇三角洲及滨-浅海三大沉积体系。沉积演化经历了早期蒸发性海湾、中期浅海盆地、晚期陆缘广海的过程。泻湖相堡坝亚相、三角洲相前缘亚相以及滨海相席状砂亚相是砂岩储层分布和发育的最有利相带。

| Abstract: | This paper researched sedimentary styles and characteristicsand discussed about Carboniferous sedimentary evolution of different stages, and, furthermore, analyzedcharacteristics and distribution of carboniferous clasticreservoir, and main controllingelementsof geophysical attributionin order tocarryout integrative estimation of reservoirin Bayanhotbasin. Bayanhot basin hasthree depositional systems including lagoon-tidal flat, delta-fan delta and offshore shallow sea. Sedimentary evolution underwent threestagesincluded in the evaporation sea bay of the earlier stage, shallow sea basin of the middle stage, extensive sea of the continental margin. Sand bar sub-facies of lagoon, front delta,sheet sandstone of offshore sea are the best sedimentary facies belts for the oil & gas accumulation. |
