二连盆地宝勒根陶海凹陷北洼槽下白垩统构造-沉积响应特征
Lower Cretaceous Cedimentary-Structure Response Characteristics of Baolegentaohai Sag North Subsags in Erlian Basin
摘要
Abstract
The drilling and earthquake research material shows that Baolegentaohai sag north subsags de-velopt Saihantala Formation, Tengger Formation, Aershan Formation and the Jurassic stratum, Lower Cretaceous, for asymmetric single broken unsymmetrical fault-depression sag. According to different areas of sedimentary structure characteristics, the sag can be divided into eastern steep belt, central subsags belt the west slope inside belt and outside belt count up four subprime onits. Baolegentaohai sag fault sys-tems mainly composed of the eastern boundary large faults controlled and its derived level 2 or 3 fault, based on the principle of east to north fault, the faults controlled the formation of sediment-ary and struc-ture. The westfaulting east overlapping of Baolegen- taohai sag geologic structure controlled the exhibition of sedimentary facies belt , many structural movements formated serial sedimentary break and transgres-sion (source center), sedimentary formations that is nearer provenance, multiple origins and coarse sedi-ment, the sand types were fandelta, braid river deltas and nearshore subaqueous fan, reservoir type was low compositional and textural maturities of turbidites and middle-low porosity and low- low penetrance. The hydrocarbon generation center of ramp zone and central subsags belt in north lord subsags area are fa-vorable zones for the stand industrial reservoir.关键词
