基于储层构型的流动单元划分及对开发的影响
Flow Units Classification Based on Reservoir Architecture and Its Influence on Reservoir Development
摘要
Abstract
Reservoir heterogeneity is severe and fluid flow is very complex in delta reservoir,which limits the reservoir development. Taking E1 f 43 reservoir of Nanhu Oilfield as an example,flowing barrier recognition method based on reservoir architecture and flow unit classification method based on multiparameter cluster analysis and stepwise discriminate analysis are used. Flow barrier distribution and flow unit development rule are studied with the above methods and development data. Connection of different flow unit composite models is analyzed and the influence of flow barrier and flow difference on oil development is summarized. The study revealed that:(1)developed two kinds of reservoir sandbodies,sheet sand and stripped sand. In stripped sand,water injection is usually invalid because the injection well and oil well are separately in sand and flow barrier. This forms remaining oil.(2)Developed 5 types of flow units and types II and III are the main types.(3)There are 5 different flow unit composition model in connected sand bodies which have different connectivity,which form flow difference surfaces inside connected sand bodies and weaken the permeability. These surfaces limit the reservoir development and enrich remaining oil.关键词
