摘要
宝勒根陶海凹陷位于二连盆地腾格尔坳陷南部,是伸向温都尔庙隆起方向的一个狭长的单断箕状凹陷。下白垩统地层自上而下包括赛汉组、腾格尔组(包括腾二段、腾一段)、阿尔善组(包括阿四段、阿三段、阿二段)。碎屑岩储层成岩作用主要有机械压实作用、胶结作用、交代作用、泥质杂基的重结晶转化作用、溶解作用和构造作用等,其中最显著的成岩作用是压实作用、胶结作用、交代作用和溶解作用。成岩阶段以井深800m为界划分为早成岩阶段B期和晚成岩阶段A期两个阶段。
The Baolegen Taohai Sag located in erlian basin in southern TengGeEr faulted reservoir,uplift the direction of a narrow single off dustpan depression.From top to bottom,Lower strata Cretaceous includes race Han group,the Tengger group(including Sec.Teng 1 Teng 2 paragraph),Arxan group(Arxan 4 paragraph,Arxan 3 paragraph,Arxan 2 paragraph).Diagenesis of clastic reservoirs include compaction,cementation,metasomatism,muddy matrix recrystallization transformation,dissolution and tectonism,One of the most significant diagenesis is compaction,cementation,metasomatism,and dissolution.Diagenetic stage to a depth of 800m as the boundary is divided into two stages of early diagenetic stage B and late diagenetic stageA.
