沉降模拟的模型改进及系统研制

The Improvement of Model and Development of Software for Basin's Subsidence History Analysis

沉降史分析是盆地分析的重要内容，也是研究盆地构造运动学和动力学的重要途径之一．本文在分析现行的盆地沉降史模拟基本原理和方法的基础上，指出了盆地沉降史模拟存在的问题，讨论了可能的解决方案．最后介绍了作者研制的沉降史模拟系统．

In this paper the writers give a summarize of subsidence history analysis andits principle and routine of subsidence history analysis, in detail some problemssuch as erosion, porosity--depth relation, density-depth relation, salt layer and interlayered bedding are discussed. A programme for subsidence history analysis ispresented. At the end of the paper an example in Huanghua depression of Bohaigulf basin is given to demonstrate the using of this program, the results includeplaeo-depth, plaeothickness, tectonic subsidence, depositing and subsidencing velocity, development of basement, as the result both data and sketches are given.
