摘　　要：中原油田经过多年的开发,已整体进入中高含水阶段,地层压力发生了很大变化,加上酸化、压裂等各种储层改造措施的实施,使得储层孔隙特性、流体及压力分布等变得越来越复杂,并且由于层间差异大,增产增注措施效果越来越不理想,故近几年先后开展了以聚合物驱为主的三次采油措施。注聚合物后,储层非均质性、地下流体的性质和流度发生了变化;依靠试井技术,通过对化学驱采油效果不同阶段测试分析评价,研究化学驱油气水运动规律及其开采特点,结合动静态认识,分析储层特征、流体及压力场分布,为进一步提高化学采油效果提供有价值的科学依据。After years of development,Zhongyuan oilfield has entered the stage of high water cut overall,formation pressure,great changes have taken place,and all kinds of reservoir reconstruction measures such as acidification and fracturing,the reservoir pore properties, fluid and pressure distribution is becoming more and more complex,and because the big difference between layers,increase the measures injection effect is more and more not ideal,therefore,in recent years has carried out the measures is given priority to with polymer flooding the tertiary oil recovery.After polymer flooding,reservoir heterogeneity,the nature of the subsurface fluid and mobility has changed;Well test technology,and through the effect of chemical flooding oil production to analysis and evaluate the different stages of testing the characteristics of chemical flooding water movement rule and its exploitation of oil and gas,combining with dynamic and static understanding,analysis of reservoir characteristics,fluid and pressure field distribution,in order to further improve the effect of chemical production provide valuable scientific basis.
