摘　　要：稠油产量递减分析和蒸汽吞吐优化设计是稠油油田开发规划中的重要内容,因此,应用灰色系统理论中的关联分析原理,确定了产量递减的主要影响因素;在数值模拟的基础上,用灰色关联分析方法对注汽温度、注汽干度、注汽速率、周期注汽量及焖井时间进行了方案优化设计,并给出了具体的应用实例。结果表明,该方法计算简单,结果可靠,在信息不完备、数据有限的条件下运用该方法可扩大信息源,提高评价分析和方案优化的可信度,为经济开发稠油油田提供理论依据。Heavy oil production decline analysis and optimal design of steam soak is one of the important contents in the heave oilfield development programming,therefore,applying the Correlation analysis in grey theory,the main factors affecting production decline are determined. And based on the Numerical Simulation,the Correlation analysis is used as a tool for optimized design of steam injection scheme including steam injection temperature,dryness fraction of steam,steam injection rate,cyclic injection volume and soak time,also it provides an idiographic.the result indicates that this method is simple,reliable in calculation,in addition,on the condition that the information is imperfect and data are limited,this method can extend information source,and can improve evaluation analysis and schemes optimization’s reliability,thus providing theoretical basis for economical development of heavy oil reservoir.
