摘要
根据基准面旋回识别标志,运用高分辨率层序地层学理论和方法,对甘谷驿油田顾屯探区延长组长6段油层进行了划分。识别出各级别旋回层序界面,并将其划分为长期、中期、短期旋回层序,应用地层等时对比,以长期旋回层序为地层对比格架、中期旋回层序为地层对比单元,建立了长6油层组等时地层格架。
Based on sequence identification markers,chang 6 oil formation in Ganguyi area was divided by high resolution sequence stratigraphic theory and method.According to interface types,the lower jurassic sequences can be divided into serveral base-level cycle sequences.By using the technology of isochronous stratigraphic correlation of high resolution sequence stratigraphy,the isochronous stratigraphic framework was established with long-term base-level cyclic sequence as stratigraphic correlation framework and middle-term base-level cyclic sequence as contrasting unit.
