摘　　要：影响自然递减的主要因素是油藏的非均质性、采油速度及注采开发措施等。完善井网、合理的层系细分、调整产液及吸水剖面、动用薄差层和低渗透层等可以控制油藏自然递减。研究表明 ,高效的产能接替、保持切合实际的采油速度、调整合理的产液及注水结构。The main factors that influence natural decline are the heterogeneity, oil production rate, water content ratio, injection-production measures, injection water quality and so on. The natural decline may be controlled by well pattern improving, reasonable strata series subdividing, liquid production-injection profile adjusting, thin-and-poor formations and low-permeability formations producing etc. The research presents that the effective way to control the natural decline in heterogeneous oil reservoirs is to keep high-effective productivity and suitable oil production rate, to adjust reasonable producing liquid and injection structure, and to change effective strata series in development.
