Abstract: Taking fluvial and deltaic reservoir in Shengli Oilfield as an example and applying the multi-subject theory and many methods such as core rock analysis,log evaluation,physical simulation and numerical simulation on reservoirs,the characters and rules of variation of macro parameters for the reservoirs in the process of water flooding development in continental faulted basin were investigated.The mathematical model and predictable model for calculating macro parameters of reservoir flow field in special high water cut development stage were built up.The variation mechanism of macro parameters for reservoir flow field in the period of water flooding development was discussed.The research result shows that the development liquid has a great effect on permeability of reservoir while it has no effect on the porosity of reservoir.The dynamic geological process is the main factor resulting in the change of macro parameters of reservoir.

摘要： 以胜利油田河流三角洲储层为例,综合应用多学科理论以及岩心分析、测井储层评价、物理模拟和油藏数模等多种方法,研究了陆相断陷湖盆高渗透储层和中、低渗透储层在长期注水开发过程中油藏流场宏观参数变化规律,建立了特高含水期宏观参数变化规律的数学模型和预测模型,探讨了油藏流场宏观参数的变化机理。研究结果表明,油藏开发流体对储层渗透率的改造作用最大,对孔隙度的影响较小,油藏开发流体的动力地质作用是导致储层宏观参数变化的主因。
