Five types of sequence boundaries within the third-order sequence of Donghe sandstone in Tarim Basin are recognized through the detailed analysis of outcrop and core data:the third-order sequence boundary

parasequence group boundary

parasequence boundary

stratum group boundary

and stratum boundary.Based on the response characters of conventional logging and dip logging through sequence boundaries

the standards and methods of sequence boundary identification using logging data are proposed

including the identification model of conventional logging data

the identification model of dip data with long window-length processing

the identification model of original dip-logging conductivity curves

the identification model of precise dip-processing data

etc.By applying the above-mentioned models to the multi-sequence boundary identification and correlation in all wells of the oilfield

five orders of sequence boundaries are identified

and one third-order sequence

one parasequence group(sandbody group)

twelve stratum groups(substratum zone) and fifty stratum(single sandbody) are recognized.As a result

the high-resolution sequence stratigraphic framework of Donghe sandstone is established.
