摘要:
为揭示苏丹 Muglad 盆地 Fula 凹陷Jake地区层序地层特征及沉积体系分布规律,应用层序地层学及沉积学理论和方法,综合利用岩心、测井和三维地震资料,建立了Jake地区层序地层格架,将早白垩世进一步分为7个三级层序,确定了研究区沉积相类型及分布特征。研究结果表明,Jake地区白垩系由于构造活动较为活跃,水深的变化造成快速的沉积相变,其中Abu Gabra组沉积类型由深水沉积变化为浅水沉积,由下至上依次发育扇三角洲-水下扇-辫状河三角洲沉积,Bentiu组沉积时构造较为稳定,垂向上从辫状河-曲流河演化为三角洲。
Abstract:
In order to reveal the sequence stratigraphic characteristics and sedimentary system distribution law,the sequence-stratigraphic and sedimentologic theories and methods were employed in the Cretaceous of Jake Oilfield in Fula Sag of Muglad Basin,Sudan.The core,logging,and 3-D seismic data were comprehensively used to establish the sequence stratigraphic framework,determine the types and distribution of sedimentaryfacies,and understand evolution pattern and controlling factors in the formation.The early Cretaceous can be divided into 7 three-order sequences.Due to the active tectonic activity,the depth of water varied and depositional facies varied vertically from fan delta to submarine fan and then to braided river delta in Abu Gabra Formation. In comparison, the tectonic activity of Bentiu Formation was inactive and depositional facies varied from braided river to meandering river and then to delta.
