Analysis of High-Frequency Sequence Stratigraphy Architecture of Putaohua Oil Layer in Sanzhao Sag of Songliao Basin

Abstract:

Using high-resolution sequence stratigraphy theory and its technology, based on 22 well cores and 4 256 logging data, interface types and characteristics of different grades the base-level cycle in Putaohua oil layer of Sanzhao Sag was systematically analyzed, and Putaohua oil layer is divided into 1 medium-term base level cycle, 4 short-term base level cycles, 8 super-short-term base level cycles, established high-resolution sequence strata framework, and proposed sequence stratigraphy model of middle super-short-term base level cycles meridionally grado-thin and up to vanish with syndepositional structure lifting control in the south of Putaohua oil layer. Sandstone is offlap Pinch-out in the upper of Putaohua oil layer, and Sandstone is onflap Pinch-out in the under of Putaohua oil layer from north to south.
