| 摘 要： | 提出以地震剖面控制地层对比的总体框架 ;以附近的野外露头剖面控制层组划分 ,利用野外剖面的岩性组合特征来进行地层层序对比 ;未钻井前在野外剖面上寻找可能的特征标志层 ,与钻井剖面进行细致的地层对比 ,确定标志层后再进行层组划分及小段对比的地层对比方法。即地震控制大框架 ,组合层序控制大套层位 ,标志层控制层组及小层的对比方法。较好地解决了区域探井或参数井地层的划分和层位的预测。

| Abstract: | This paper regards the seismic section as a general frame controlling stratigraphic correlation,controlls the horizon classification with its nearby field outcrop section and correlates the stratigraphic sequence according to characteristics of rock assemblage of the field section.Before drilling,we must find out the characteristic key bed in the field section,correlated in detail with the strata of drilling section.The strata must be classified and correlated after the determination of key bed.This stratigraphic correlation method can well solve the problem in stratigraphic classification and horizon prognosis of regional well or parameter well. |
