以高分辨率层序地层学原理,利用沉积露头、岩心和测井等资料,对赵凹油田安鹏区核三段不同级次的基准面旋回进行划分。采用“旋回对比、分级控制”的原则,以洪泛面S1-S5为标志层,将核三上中期旋回划分为4个中短期旋回。 Based on the high-resolution sequence stratigraphy theory, the datum cycles of different grades of the third member of the An Peng district in the Zhao-Au field are divided by the data of sedimentary outcrops, cores and logs. Using the principle of “Cyclical contrast, grading control ”, taking the S1 - S5 floodplain as the index layer, the mid-term and intermediate-term cycles of the core three are divided into four short-term cyclones.
