%X 某油田B油藏为边底水发育的中孔、中高渗透储层，夹层发育。经过较长时期的高速开发后，剩余油分布十分复杂，底水锥进是开发面临的最大问题，而夹层存在又控制着油水在油藏中的运动，特别是控制着底水向上运动，因此认识油水运动规律非常困难。B油藏目前处于中–低含水开发阶段，本文采用4种宏观剩余油分布研究方法研究，开展动静态综合分析与数值模拟相结合的精细剩余油分布研究。通过剩余油分布规律认识，从平面上分井区细化，纵向上分小层落实了剩余潜力，研究成果为优化开发调整方案提供有力的技术支持，为今后同类型相近开发阶段的油田提供了一套科学合理的精细油藏描述技术。<br />
B reservoir of an oilfield is a medium porosity, medium high permeability reservoir with edge and bottom water, and interlayer is developed. After a long period of high-speed development, the distribution of remaining oil is very complex. Bottom water coning is the biggest problem faced by the development, while the existence of interlayer controls the movement of oil and water in the reservoir, especially the upward movement of bottom water, so it is very difficult to understand the law of oil and water movement. At present, reservoir B is in the stage of medium low water cut development. In this paper, four kinds of macro remaining oil distribution research methods are used to carry out the fine remaining oil distribution research combining dynamic and static comprehensive analysis and numerical simulation. Through the understanding of the distribution law of remaining oil, the remaining potential has been realized by dividing the well area from the plane and the small layer from the vertical. The research results provide strong technical support for optimizing the development and adjustment scheme, and a set of scientific and reasonable description technology of fine oil reservoir for the oil fields of the same type and similar development stage in the future.
