ABSTRACT: Taking
the fluvial reservoir of the Neogene Minghuazhen Formation in Bozhong S
oilfield in China as an example, a detailed study of the interlayer in the
reservoir was conducted. From the perspective of sedimentary genesis of the interlayer,
three types of genesis of the interlayer are summarized and analyzed, namely,
fine grain sediment in the inter peak channel, suspended sediment in the post
flood channel, and abandoned channel sediment. At the same time, combined with
seismic waveform analysis, the distribution characteristics and morphology of
the interlayer in complex fluvial facies oilfield are carefully depicted, and
the horizontal well optimization implementation is guided based on the planar
and three-dimensional spatial distribution characteristics of the interlayer.
This method enriches the characterization technology of interlayer in offshore
oilfields, and has important guiding significance for the overall evaluation
and development research of complex fluvial facies oilfields.
