莺歌海盆地DF13区黄流组沟道砂体特征研究
Study on Characteristic of the Sand Bodies of Huangliu Formation in DF13 Area,Yinggehai Basin
摘要
Abstract
The massive fine-grained sandstone developed from the thick mudstone lager powder of late Miocene deposits in shallow yellow stream group in Yingge Sea Basin is the recent gas exploration hotspot. The reservoir is sand vertically stacked multi-stage,and changes fast horizontally. Though tectonic evolution and ancient deposition setting control the distribution and evolution of third-order sequences framework within Huangliu Formation,they do not control the distribution of depositional systems or reservoir sand bodies. Compared with the classic submarine fan phase,typical deposition characteristics can hardly be found in this depositional system like obvious fan body sub-phase differentiation,main waterway,levee,etc. It is consid-ered as a channel sand bodies’ combination of small-scale,fast migration,and thick accumulation. In the article,it is called non-typical Turbidity current,using different channels+spring current to show this sedimentary characteristic. The studies suggest that the unstable continental slope setting controls the distribution of sand bodies in four-order sequences by means of controlling the Palaeogeomorphology and sedimentary source rechargement. According to the hydrodynamic characteristics and accumulation styles of the channel deposition,the sand bodies are further divided into the sub-erosion channel,migration channel and filling structure. Among them sub-erosion channel and filling structure have good reservoir conditions,that can be new gainful exploration targets.关键词
