珠江口盆地番禺低隆珠江组—韩江组高精度层序地层
|
摘要
以岩心、测井和三维地震等资料分析为基础,结合古生物分析,将珠江口盆地番禺低隆起新近系珠江组到韩江组划分为7个三级层序,归为明显削蚀不整合明显上超不整合、底超不整合弱削蚀或上超不整合和整合界面等。每个三级层序内以主要水进面为界划分出3～4个四级层序。结合地震属性分析,揭示了四级层序框架内沉积体系的分布和发育。受古地貌和相对海平面变化的控制,高位域三角洲砂体主要分布于隆起及以西地区,低位域三角洲前缘砂体主要分布于隆起-缓坡坡折带。概括出高精度层序地层格架内4种潜在的非构造圈闭发育模式并进行了分布预测,认为东部的低位域三角洲前缘砂体和东南部的断裂坡折带下的低位域三角洲前缘砂体,具有良好的成藏条件,易形成构造-岩性或岩性地层油气藏。
The Neogene Zhujiang Formation and Hanjiang Formation of Panyu low uplift in the Zhujiang River mouth basin were divided into seven sequences on the basis of an analysis of outcrops,cores,logs,3D seismic information and palaeobiologic characteristics. Some were assigned to obvious truncation or obvious overlapping and unconformity,and the others to gentle truncation or overlapping unconformity and conformity. Every thirdorder sequence was divided into system tracts and fourth-order sequences whose boundaries seem to be main flooding surfaces. Combined with the seismic attributes,the distribution and development of the depositional systems in the fourth-order sequences were revealed. Under paleogeomorphologic conditions and relative sealevel change control,the deltaic sand bodies in the lowstand tract system were distributed in the uplift-gentle slope-break zone. In the highland system tracts,however,they were distributed in or west of the uplift zone. This paper has divided the stratigraphic traps into four types with a prediction of their distribution. The lowstand sand bodies in the southeastern syndepositional fault slope-break zone and in the east have good hydrocarbon pool-forming conditions,which are hence considered to be favorable for the formation of structural-lithologic traps or lithologic traps.
