从深入分析砂体成因类型与基准面旋回过程的关系出发,详细讨论砂体在地层格架中的发育位置和分布规律,以及作为较长期层序界面的侵蚀冲刷作用对其两侧砂体的几何形态、稳定性和储集性等特征的直接控制作用,在此基础上,提出基于高分辨率层序分析的、在地层格架中进行相当时间—地层反演的砂体等时追踪对比新技术方法,并较为详细地介绍了这一技术方法的工作原理、操作流程,和相控模式条件下的“等高程、非同期、异成因”和“非等高程、同期、异或同成因”砂体的两种等时对比模式。 Based on the deep analysis of the relationship between the genetic type of sand body and the cycle of the reference plane, the development position and distribution of sand body in the stratigraphic framework and the erosion erosion of the longer-term sequence boundary are discussed in detail. Geometry, stability and reservoir characteristics. On the basis of this, the isochronous tracing of sand bodies based on high resolution sequence analysis and time-stratigraphic inversion in the stratigraphic framework is proposed New technology and method, and introduced in more detail the working principle, operation flow and “non-equal, non-synchronous, heterogeneous” and “non-equal elevation, synchronicity, Same cause ”Sandstone two isochronous patterns.
