摘要
近年来层序地层模拟在盆地研究中起着重要的作用 ,根据层序地层模拟结果可预测沉积相的分布和结构 ,检验和修正地震剖面的解释 ,对地层的基本控制因素作出评价。文中论述了层序地层模拟软件的开发原理和方法 ,详细介绍了层序地层模拟流程图、构造沉降模型、沉积作用模型、沉积物压实模型、负载沉降模型和侵蚀作用模型。依照所述内容读者可以开发出自己的模拟软件
In recent years,sequence stratigraphy modeling has been playing an important role in sedimentary basin analyses. It can be used to predict distribution and architecture of different facies, test and correct interpretation of seismic sections,and evaluate fundamental controls on basin stratigraphy. This paper introduces principle and method to develop software for sequence stratigraphy modeling,and discusses in detail modeling process chart and several models such as tectonic subsidence, sedimentation,sediment compaction,loading subsidence and erosion. Based on these discussions,readers can develop software for sequence stratigraphy modeling themselves.
