摘　　要：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.To discuss the non-synchronous change of accommodation space and sequence stacking patterns in both sides of a basin, using the SEDPAK two-dimensional stratigraphic modelling program, the ＂transformation system of the accommodation space＂ within a basin was simulated by considering the various parameters controlling the deposition of a sequence. The simulation results indicate that isochronous sequence stratigraphy within a basin may exhibit both synchronous and non-synchronous stacking patterns at different part of the basin. Synchronous stacking patterns were observed to be primarily developed during the lowstand system tracts and the late highstand system tracts. Non-synchronous stacking patterns were found to be often associated with the transgressive system tracts and the early highstand system tracts. The development of non-synchronous stacking patterns may occur under a number of circumstances within a basin with the right combination of various parameters. Nonsynchronous stacking patterns of isochronous sequence stratigraphy may provide new reference to identify system tracts interface and develop sequence stratigraphie correlation.
