【摘要】：储层细分对比存在的问题主要表现为两个方面:一是储层细分对比的结果往往是岩性单元,多不具等时性;二是储层细分对比的结果仍不够精细,不能满足高含水阶段剩余油挖潜的需要。其根本原因是对层、地层结构认识的局限性。储层细分对比以传统地层学理论为指导,认为层、地层结构符合"层状"模式,即地层是全区分布、近于水平、相互平行的,并且层与层水平叠置。然而,层序地层学等突破了传统地层学对层、地层结构的认识,认为地层不一定全区分布、不一定水平、不一定相互平行;层的空间位置变化大,相互间可呈超覆、退覆等叠置特点。构型要素分析法更细致地揭示了储层结构特征,认为原来划分的层是复合体,需进一步细分。通过层次界面划分,复合体可以被细分成一系列形态各异、分布复杂的构型单元。从问题根源入手提出相应对策,解决储层细分对比存在的问题需要以沉积学、层序地层学、地震地层学等理论为指导,运用构型要素分析法进行层次界面划分。
[Abstract]:The main problems of reservoir subdivision and correlation are two aspects: one is that the result of reservoir subdivision and correlation is often lithologic unit, and the other is that the result of reservoir subdivision and correlation is not precise enough, It can not meet the need of tapping the potential of remaining oil in high water cut stage. The fundamental reason is the limitation of understanding the formation and stratigraphic structure. The subdivision and correlation of reservoir is guided by the traditional stratigraphic theory. It is considered that the formation and stratigraphic structure conform to the "stratiform" model, that is, the strata are distributed in the whole area, are close to the level, parallel to each other, and the layers and layers are stacked horizontally. However, sequence stratigraphy breaks through the traditional stratigraphic understanding of stratigraphic structure, and holds that stratigraphy is not necessarily distributed in the whole area, not necessarily horizontal, and not necessarily parallel to each other. The characteristics of overlay etc. The structural characteristics of the reservoir are revealed in more detail by the method of structural element analysis, and it is considered that the layers originally divided are complex bodies, which need to be further subdivided. By hierarchical interface division, the complex can be subdivided into a series of complex configuration units with different shapes and distributions. In order to solve the problem of reservoir subdivision and correlation, it is necessary to use the theory of sedimentology, sequence stratigraphy and seismic stratigraphy to divide the stratigraphic interface with the method of structural elements analysis under the guidance of the theory of sedimentology, sequence stratigraphy and seismic stratigraphy.
