为探讨盆地两侧可容纳空间和层序叠加模式的非一致性变化,利用SEDPAK二维层序模拟软件,通过考虑控制层序沉积过程的不同参数,对可容纳空间转换系统进行定量模拟并提出新的认识.模拟结果表明,盆地两侧同期层序叠加模式可以分为“同步”和“非同步”两种,同步叠加模式多出现在层序的低位体系域及高位体系域后期,非同步叠加模式多出现在层序的水进体系域及高位体系域初期.多种地质参数的合理组合,盆地两侧同期层序均可形成非同步叠加模式.非同步叠加模式对体系域界面的识别、层序对比具有一定的参考价值.
In order to explore the inconsistent change of the accommodation space and sequence superimposition pattern on both sides of the basin, the SEDPAK two-dimensional sequence simulation software was used to quantitatively simulate the space conversion system by considering different parameters of the control sequence deposition process New understanding.The simulation results show that the superimposed pattern of contemporaneous sequence superimposed on both sides of the basin can be divided into two kinds, “synchronous” and “asynchronous”, and the synchronous superimposed pattern mostly appears in the lower and upper system tract of the sequence In the later period, the non-synchronous superposition pattern mostly appeared in the initial stage of the sequence system of water-system system tract and high-level system tract.A reasonable combination of various geological parameters could form a non-synchronous superposition mode in the same sequence on both sides of the basin.The non- Domain identification, sequence comparison has some reference value.
