摘要：

提出了井震基准面旋回匹配的概念与方法。该方法通过测井和地震层序地层分析，以高分辨率层序地层学的基准面旋回为约束，利用合成记录建立测井和地震反射之间的匹配关系。采用该方法可获得更可靠的井震匹配关系，并能赋予各主要地震反射轴的层序地层意义，搭建起地震层序地层与高分辨率层序地层之间的桥梁。孔南地区沙河街组30多口井的井震基准面旋回匹配研究结果表明：层序Ⅰ包括4个主要反射轴，A1、A2和A3分别代表了层序Ⅰ内部的3个四级层序初始洪泛面，A4反射轴相当于层序ⅠC3U旋回上升半旋回的初始洪泛面；层序Ⅱ内部主要包括B1和B2 2个正相位连续反射轴，分别代表了层序Ⅱ内部2个基准面旋回的洪泛面；层序Ⅲ内部主要发育了C1和C2 2个明显的正相位较连续的反射轴，其中C1相当于层序Ⅲ的C2U旋回与C3D旋回的分界，C2反射轴对应于层序ⅢC3U旋回的初始洪泛面。各三级层序内部的正相位反射轴通常为四级层序的初始洪泛面或最大洪泛面。

Abstract:

The authors propose the concept and method of seismic-log and base level cycle matching. The method established relationship between well logging and seismic reflection by the synthetic notes which is anlysised the well logging and sequence stratigraphy,and as well,the relationships must have been restricted by the base level cycle in the high resolution sequence stratigraphy.This method will get more reliable relationship between well and seism,and give the main significance of seismic reflection meaning that is in the sequence stratigraphic.At the same time,it bridge gap between seismic sequences and high resolution sequence stratigraphy.The 30 wells results of seismic-log and base level cycle matching show that sequence Ⅰinclude 4 reflection axis.A1,A2 and A3 are representing three first flooding surfaces in the four-order sequences.A4 is the first flooding surfaces in high cycle of C3U of sequence Ⅰ. Sequence Ⅱinclude B1 and B2．It is the main seimic reflection horizon and representing flooding surface in the Sequence Ⅱ. Sequence Ⅲ include C1 and C2. C1 is the boundary between C2U and C3U.C2 is the first flooding surface in the C3U cycle.The seimic reflection horizons which is in the third-order sequence are representing the first or max flooding surface which in the forth-order sequence.

Key words: Kongnan area, high-resolution sequcence stratigraphy, seismic-log and base level cycle matching, Shahejie Formation, seismic response
