二连盆地巴音都兰凹陷早白垩世构造岩相带特征及含油性
|
摘要
在系统观察岩心的基础上 ,从单井相分析入手 ,结合地震相和测井相模式 ,以及大量岩矿、粒度等分析化验资料 ,对巴音都兰凹陷下白垩统巴彦花群的物源方向、沉积体系、构造岩相带及含油性进行了研究。认为区内具有东、西两大物源区、五大水系控制着 11个砂体的平面展布 ,最终 ,划分了扇三角洲等 5种沉积体系 ,总结出具平台型陡坡扇三角洲等 6种构造岩相带 ,并着重对有别于典型单断箕状凹陷的 3种构造岩相带的含油性进行了初步探讨。
Based on data of core observation,individual well facies analyses,seismic and logging facies models,and numerous lithological analyses,the provenance,depositional systems, structure petrographical zonations and their oil bearing properties of the Early Cretaceous in the Bayindulan sag of the Erlian Basin are studied.It is suggested that there are two large provenance areas in the research area, including eastern and western source areas.It is believed that there were five large drainage systems which controlled the distribution of a total of eleven sand bodies.As a result of facies analyses,five depositional systems including fan delta are recognised.Six types of structure petrographical zonations, such as the type of steep slope fan delta structure petrographical zonation with platform,are summarised.Three of these structure petrographical zonations are different from the typical single rifted sag and are discussed in detail for their oil bearing properties.
