碎屑岩储层流动单元研究的新进展

储层流动单元是指影响流体流动的岩性和岩石物理性质在内内部相似的，在垂向上和横向上连续的储集带，流动单元可以解释油水井连通关系，提高剩余油采收率，提供油田开发后的挖潜对象，对于二次采渍和三次采油具有较大的实际 意义，目前流动单元的研究中仍存在着时空尺度和参数选择的问题，这些问题的解决必将大大推动储层地层研究向精细化，系统化发展。

The Latest Development in Flow Units of Detrital Reservoir

A flow unit is defined as a volume of reservoir rock that is continuous laterally and vertically and has similar lithology and physical property that affect fluid flow. It can offer us object to explore at the late stage of oil-field development and has important practical significance for secondary exploitation and tertiary exploitation. At present, there are many problems existing in flow units exploration, such as how to define a flow unit size and how to select parameters to divide flow units. To solve these problems will accelerate the development of flow units.
