摘要

从物源与地震相两个方面入手,深入研究了江汉盆地陈沱口凹陷新沟嘴组下段的沉积相展布特征,明确了陈沱口凹陷存在华容隆起与老新-新沟两支物源。通过地震波振幅、频率、连续性、内部结构以及外部形态等特征研究,将陈沱口凹陷目的层划分为3种地震相类型,再结合物源分析的结论与井-震转换,将地震相转化为沉积相。研究表明,陈沱口凹陷新沟嘴组下段主要发育扇三角洲相与湖泊相两大沉积体系。
From seismic facies and provenance,sedimentary facies distribution characteristics of the lower member of Xingouzhui Formation in Chentuokou Depression were deeply studied,the provenances of Huarong Uplift and Laoxin-Xingou Area in Chentuokou Depression were clarified.Through studying the characteristics of seismic wave amplitude,frequency,continuity,internal structure and external morphology,target zones in Chentuokou Depression were divided into three seismic facies types,and combined with the result of provenance analysis and well-shock conversion,seismic facies was converted into sedimentary facies.Research shows that the lower member of Xingouzhui Formation in Chentuokou Depression mainly develop fan-delta facies and lacustrine depositional systems.
