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
