The pool-forming pattern in the condition of arching in the southeast uplift in Songliao Basin
Online published: 2007-03-15
The southeast upwelling area is first-order tectonic unit of Songliao Basin from the research of structural evolution in south of Songliao Basin.Under the effect of tectonic reversal during the end period of Nenjiang and Early Tertiary,the southeast upwelling area is in the state of uplifting all the time, which caused Nenjiang Group eroded seriously.And it did not accept the Sifangtai Group and Mingshui Group of Cretaceous and Teriary sediment, which caused the thinning of sedimentary seal and the influence on the diagenetic evolution, drainage, geotemprature and geopressure fields.This state not only controls the migration,accumulation and reservoir-forming,but also changes the hydrocarbon-generation.So the accumulation condition is complicated.It is significant to buildup the reservoir-forming model of the residual reservoir, secondary hydrocarbon reservoir and reservoir controlled by mature source rocks formed in late period for the exploration of oil and distribution.
