| “红层”地层缺乏古生物,俗称“哑地层”，地层地质年代研究难度大，缺乏稳定的岩电标志，等时对比缺乏有效 的方法手段。利用古生物、录井、测井及地孬等资料对“红层”的地层特征、层ff地层对比理论和对比方法进行研究。 结果表明红层”缺乏明显的低水位体系域沉积,湖平面主要受季节性洪水控制，地层明显呈现出二分件的特征； 将Vail与Cross两套U序地层学理论体系有机结合，可以有效地解决“红层”地层划分难的问题;通过“宏观界面约 束-内部精细旋问划分-多W素综合”的地G对比方法流程可以很好地建立研究区的M序地层格架。 |

| Abstract: |
| TTie red IhhIs are commonly known as M the barren stratum" because of lacking paleontoLc^cal fossils. For the difficulty in the strata geologic age research and the shortage of stable rock electric signs，there are many difficulties in the isochronous correlation research. Based on palaeontology, logging, well losing and seismic, the strata feature, correlation theory of sequence stratigraphy and correlation method of the red beds were studied. Hie results show that the red beds take on the dichotomy clearly because of the lark of low stand systems tract sediment and the lake leveJ is controlled by seasonal flood. The difficulty of strati-graphic division for the red beds could be solved effectively ihrough dynamic integration of the theory of sequence stratigraphy of "Vail+Cross". A fine stratigraphic framework suitable for the study area can be established by the method of stratigraphy analysis, which is " iruuiro-lnterface constraint, internal-fine cycle division, controlled by multi-factor method". |
