综合考虑陆源碎屑物供给、内源碳酸盐沉积、沉积物侵蚀与再沉积、重力沉沉积以及构造升降和水平位移等诸多地质因素,建立了一个能够模拟各型盆地层序地层的综合数学物理方程式.采用自行研制的定量层序地层模拟系统,以断陷湖盆陡坡带(泌阳断陷双河一赵凹地区)为例,在假定出平面变化呈一正弦函数曲线,物源供给速率中等、匀速的条件下,分别模拟了盆地加速沉降和减速沉降两种过程的陆相层序响应特征.研究结果表明,一个构造沉降旋回过程控制着一个陆相层序及其体系域的发育和形成.
Considering the geological factors such as terrigenous detrital material supply, endogenous carbonate deposition, sediment erosion and redeposition, gravity sedimentation and tectonic movements and horizontal displacements, a comprehensive mathematical model that can simulate the sequence stratigraphy of various basins Physical equation.Using a quantitative sequence stratigraphic simulation system developed by ourselves, taking the steep slope fault basin (Shuanghe-Zhaojiao area in Biyang fault depression) as an example, assuming that the change of plane shows a sine curve, The results show that a tectonic subsidence cycle controls the sequence of a continental facies and the development of its system tract And formed.
