松辽南部四方坨子地区井-震统一的高分辨率层序划分与对比
|
摘要
当前国内主要用钻井资料建立高频层序地层格架,地震资料应用偏少,只是选一些典型的基干剖面进行分析,这样不可避免的导致一些穿层现象。以松辽盆地南部四方坨子地区上白垩统青山口组—姚家组为解剖对象,在钻井层序划分的基础上,充分应用地震资料,通过制作合成地震记录,建立了地震与钻井相互统一的3～4级层序地层格架,共划分出四个三级层序(其中青山口组三个,姚家组一个)和20个四级层序。
Analysis and analogy of sequence are the most basic contents in the study on sequence stratigraphy.Currently,it is main way to establish high-frequency sequence stratigraphic framework by application of drilling data,and the application of seismic data,but the typical primary profile analysis,is less in China,thus to lead to some cross-layer phenomena.The key of sequence stratigraphy research is comprehensive utilization of outcrop,paleontology,logging and seismic data,and the high-resolution core,logging and three-dimensional seismic data is three basic components of sequence stratigraphy analysis.It will be finally possible to establish more actual sequence stratigraphy framework by mutual verification of these three types of information.Based on drilling sequence and seismic data,the well seismic unified stratigraphic framework is established by using synthetic seismogram,which is a reliable basis for analyzing the sequence stratigraphy internal characteristics and searching for hidden hydrocarbon traps.This paper established the 3-4 grade sequence stratigraphy framework of seismic and drilling mutually unified,which was divided into four third-order sequences(of which three in Qingshankou Group and one in Yaojia Group) and 20 fourth-order sequences in Qingshankou-Yaojia group of Upper Cretaceous in Sifangtuozi area of southern Songliao Basin.
