摘　　要：根据不同开发阶段的钻井、测井、室内驱替实验及各项生产动态资料,建立了唐家河三断块储集层物性参数随注水开发过程而变化的四维动态演化模型。1971—1982年孔隙度、渗透率年相对减小率分别是1.63%和2.58%;1982年后孔隙度、渗透率年相对增大率分别是1.00%和5.57%.分析引起储集层参数在开发不同时期变化的原因主要包括:油藏温度、压力的降低、流体性质的改变及注入水动力作用所引起的岩石性质和微观结构的变化。用所建立的四维储集层参数动态仿真模型预测了不同开发阶段流动单元内部油水运动特点及剩余油分布状况,结果表明,与同期相应油水井的生产状况基本吻合。Based on the drilling, well logging, core lab displacement experiment and various production performance data, the 4D dynamic evolution model for reservoir physical parameter changes with waterflooding process in Fauhblock-3 reservoir in Tangjiahe oilfield is developed. The production history in this oilfield showed that during 1971-1982, the porosity and permeability in this reservoir relatively declined by 1.63% and 2.58%, respectively; after 1982, the porosity and permeability relatively increased by 1.00% and 5.57%, respectively. The reasons for the changes of rock property and microscopic structure caused during different exploitation periods mainly include： reservoir temperature and pressure drawdown, fluid property change and injected water hydrodynamism. With this 4D model, this paper predicts the oil-water behavior and remained oil distribution status within producing units during different development stages, the results indicate that they are close to actual production status of corresponding producers and injectors at that time.
