| 摘 要： | 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。 |

ISOCHRONIC CORRELATION OF SANDYBODIES BY HIGH-RESOLUTION SEQUENCE TECHNIQUE |
|
| Abstract: | As one of the most foundational and important matters in the study of oil-gas reservoir geology and exploitation engineering, the isochronically tracking correlation of sandybodies is a key technique to solve relevant problems.In this paper,the stratigraphic horizon and distribution of sandybody in the base-level cycle is discussed and the relationship between genetic type of sandybodies and procession of the cycle is analyzed.It controls the geometry, stability, reservoir property of sandybodies at both sides by erosion of long term sequence boundary surface. A new technique of isochronical tracking correlation of sandybody is proposed in the paper, which is obtained from high-resolution sequence stratigraphy and age-stratigraphic playback in moderate time duration. And an isochronic sandybody correlation model controlled by lithofacies is proposed with reference to the principle and operation procedure of technique. |
| Keywords: | isochronic correlation sandybody high-resolution sequence stratigraphy stratigraphic framework base-level cycle development of oil and gas reservoir |
