摘要
Abstract
Muglad Basin of Sudan is an important hydrocarbon accumulation zones,and influenced by the re-gional structure,the Early Cretaceous sedimentary reservoir developed evolution is closely related with tectonic evolution.On a basis of the comprehensive study of the seismic,well logging and core data,the characteristics of sedimentary sequence of the Early Cretaceous of the western trend of block 4 in Muglad Basin and its control-ling factors are studied.The main results and achievement are as follows:(1 )The basin has experienced three large rift movements and three thermal subsidence depression movements of post-rift stage,and formed 6 se-condary-order sequences.In those secondary-order sequence stratigraphic frameworks, the target formations from Cretaceous Abu Gabra to Paleogene Adok are divided into 13 third-order sequences;(2)Lacustrine and braided delta sedimentary systems mainly developed at rift stages,and braided river and delta sedimentary sys-tems mainly developed at sag stages;(3 )The study shows that the sedimentary systems development of different sequence are mainly controlled by the synsedimentary fault and tectonic evolution of rift and sag stages.关键词
