摘要:
应用构造-层序地层分析的思维,通过构造格架与地层格架的关联分析,对南堡凹陷东营组沉积充填样式与过程、控制要素进行了综合研究。通过沉降史分析,并结合区域构造演化特征,古近纪可划分为4个次级构造幕。凹陷内断裂发育,同沉积断裂及其时空配置关系对凹陷内结构和沉积体系类型及其展布起着重要的控制作用。控凹断裂直接控制了局部构造带的可容纳空间变化和古地貌形态,从而形成不同的沉积展布特征。高柳断层是南堡凹陷内最为重要的二级断裂,其活动始于Es1沉积时期,在东营组沉积时期活动最为强烈。在东营组沉积时期,高柳断层将凹陷分为南、北两个独立的沉积系统,尤其在Ed3沉积期其强烈的翘倾作用使高柳地区成为一个孤立的湖盆,直接影响到了高柳地区的沉积充填。根据东营组沉积时期同沉积断裂组合样式划分出4种断裂坡折带:断崖型、断坡型、同向断阶型和反向断阶型,为研究南堡凹陷东营组同沉积断裂对沉积格局的控制作用提供了有利的指导,具有重要的石油地质意义。
Abstract:
Under the guidance of tectono-sequence stratigraphy and the association analysis of tectonic and sequence framework, the sedimentary filling patterns, process, and controlling factors of Dongying Formation in Nanpu Sag are comprehensively studied. Through the analysis on subsidence history and regional tectonic evolution characteristics, the Paleogene can be divided into four secondary tectonic episodes. Faults are very developed within Nanpu Sag. It is found that the synsedimentary faults and their temporal and spatial configuration have significant control on the intra-sag structures, types and distribution of sedimentary system. The boundary faults control the variation of accommodation space and paleogeomorphology of some local tectonic zones, which result in forming different sediments distribution features. Gaoliu Fault is the most important secondary fault in Nanpu Sag. It starts during the Es1 depositional period, and its activity gradually reaches the strongest in Dongying Formation. During the deposition period of Dongying Formation, Gaoliu Fault divides sag into two parts, the southern and northern parts. After its development, the Gaoliu Area becomes an isolated lacustrine basin for the intensive tilting process of the fault during the sedimentary period of Ed3, which directly influences the sedimentation in Gaoliu Area. Based on the faults combination styles of Dongying Formation in Nanpu Sag, four types of tectonic slope break are identified, which are faulted scarp type, faulted slope type, concordant and antithetic faulted terrace types. These tectonic slope breaks provide a favorable guidance to the study on the controlling of synsedimentary faults on sedimentary framework in Dongying Formation, Nanpu Sag.
