层序地层学发展至今,各学派在解决实际问题上的分歧日益为人们所认识,建立统一层序地层学理论成为今后相关研究领域的一个重要方向。有别于经典层序地层学理论的水平面,基准面不可测量、难以表征的非物理面特点决定了基准面旋回时间规模的不确定性以及层序划分方案的主观性,进而影响到基准面旋回理论层序界面定义在逻辑上的合理性。从油田生产的实际问题以及学科发展的角度出发,认为必须重新定义基准面旋回,才有可能克服高分辨率层序地层学自身的缺陷,并从根本上解决基准面旋回理论和经典层序地层学之间的矛盾。在不改变基准面旋回理论体系基础上,建议基准面旋回定义修正为基准面下降到上升半旋回期间所保存下来的地层。应用该思路,重新对高尚堡油田深层Es32+3亚段进行了层序地层划分,结果表明该思路在一定程度上解决了油田目前存在的开发问题。
As the development of sequence stratigraphy so far, the disagreements between various schools on solving practical problems have become increasingly recognized. Establishing a unified sequence stratigraphy theory has become an important direction in the related research fields in the future. Different from the horizontal plane of the classic sequence stratigraphy theory, the non-measurable reference plane and the non-physical surface features determine the uncertainty of scale cycle time and the subjectivity of the sequence division scheme, The theoretical sequence interface is defined logically. From the practical problems of oilfield production and the development of disciplines, it is considered that it is necessary to redefine the plane cycle to overcome the defects of high-resolution sequence stratigraphy and to fundamentally solve the problem of datum cycle theory and classic sequence stratigraphy The contradiction between learning. On the basis of not changing the theoretical system of the reference plane cycles, it is suggested that the definition of the reference plane cycle be corrected to the level that the base plane descends into during the ascending half-cycle. Applying this idea, the sequence stratigraphic subdivision of Es32 + 3 sublayer in Gaoshangpu Oilfield has been re-established. The results show that this idea solves the existing development problems of oilfield to a certain extent.
