鄂尔多斯盆地中部下奥陶统马家沟组天然气储集层,实际是一种潮坪膏盐岩与碳酸盐岩共生的萨布哈类型,大气淡水淋滤标志显著,可分为4种储集岩,受控于沉积和成岩环境。溶孔层与致密层的叠加配置,构成了马家沟组多个含气层段。
The gas reservoirs of the Majiagou Formation,Lower Ordovician in central OrdosBasin could be divided into four types that are acturally a kind of sabkha composed ofgypsum-salt on tidal flat associated with carbonate rocks with clear leaching marks ofatmospheric water.
