南黄海盆地南部海相构造层研究新进展
New progress of research on marine stratum in the southern part of South Yellow Sea Basin
摘要
Abstract
This study focuses on the southern part of the South Yellow Sea Basin,targeting specifically at the Up-per Permian and Lower Triassic layers.Utilizing newly acquired and processed 2D seismic data,the research provides an in-depth analysis of the marine facies in the study area,and explores the potential directions for oil and gas exploration.Results indicate that the Late Permian to Early Triassic strata are extensively developed in the study area,exceeding 3 000 m in the maximum residual thickness.Fault systems in the marine facies are mainly in NW-NWW and near-EW directions,comprising both compressional fault system in marine Meso-Paleozoic and extensional one in the terrestrial Meso-Cenozoic.The fault activity could be categorized into the Indosinian and Yanshan-Himalayan epochs.Based on the planar distribution and combination characteristics of the faults,four structural styles and nine types of the fault systems were recognized.By analyzing the geological conditions of oil and gas,we believe that the marine facies of the Upper Paleozoic should be the main target as a novel prospective area of oil and gas exploration in the southern part of the South Yellow Sea Basin.关键词
