摘要
///Through the core and well logging, grain size analysis of new materials, Xinli oilfield N3 segments of three sand group of sedimentary microfacies are systematically studied. The studies suggest that target stratums were developed in wide depression basin, subsided the basement firmly, formed intended zone sand group-sublayer more coordinately, stratigraphic cyclicity more obviously. Development in N3 segments underwent atrophic period of lake basin, underlying N2 segment was a bulk of clay sedimentation of lacustrine facies. During the N3 formation period, delta area, started to integrated into formation reservoirs.
