摘要: 采用相关对比法对关键井的地层倾角测井资料进行处理,结合地质构造图反映出的构造倾向,确定倾角资料长相关处理参数;结合岩芯照片对倾角资料进行微细处理,确定短相关处理参数。利用确定的长、短相关处理参数,对哈得逊地区的倾角测井资料进行处理,建立了东河砂岩储层典型的层理和微构造倾角解释模型;对中泥岩段开展了层序地层研究,根据长窗长倾角矢量图和累积倾角图,在中泥岩段识别出1个完整的三级层序、2个准层序组和5个准层序;利用短窗长处理的倾角矢量图,结合原始电导率曲线和倾角测井解释结果,进一步识别出中泥岩段有7个岩层组和16个岩层。

Abstract:

Correlated comparison method is adopted to process diplog data of critical wells,By combining structural inclination displayed in geology structural diagram,the

long correlation processing parameters is determined.By using core photos,diplog data is finly processed,short correlation processing parameters are determined.By using

the parameters,diplog data of Hadexun area are processed,diplog interpretation models for representative beddings and microtectonics,in Donghe sandstone reservoirs are

set up,and sequence stratigraphy research for Middle mudstone section is conducted.According to long window and long dip vectogram and accumulative dip curve,one

integrated threeorder sequence,two parasequence sets and five parasequences in Middle mudstone section are identified.According to short window and long dip vectogram

,combining initial conductivity log curve and diplog interpretation models,seven terrane sets and sixteen terranes are fartherly identified.

Key words: diplog, bedding, sequence boundary, accumulative dip, correlated process parameters
