摘    要:在油田注水开发过程中,由于储层平面非均质性、流体非均质性及开发条件的影响,在平面上会出现注入水突进的情况.注水井中的注入水向不同方向驱油,推进往往是不均匀的,一般总有一个方向突进最快,且经过长期水洗之后,这个方向有可能发展成"水道",形成注入水的低效循环.建立了应用模糊综合评判方法识别低效循环井的数学模型,通过实例分析表明,运用综合评判方法识别低效循环井是一种客观有效的方法,该评价方法计算方便,易于操作和推广.

关 键 词:模糊综合评判  低效循环井  层次分析法  数学模型  权重

Abstract:During the field waterflooding process,it will appear the advancing situation of flood water,which is caused by the effects of heterogeneities of reservoir plane and fluid and development condition.When we inject water to oil displacement on different directions in water injection well,the advancing is always heterogenetic.Generally,there is one direction′s advancing that is the fastest.It may be developed to be ″a channel″ after long-term watering,which can form the flood water of deficient circulation.we set up a mathematical model that appling fuzzy comprehensive judge method to identify deficient returning well.Through analysis of living example,it is shown that it is a objective and effective method which is convenience to calculating and easy to manipulate and popularize.
Keywords:fuzzy comprehensive judge  deficient returning well  analytical hierarchy process  mathematical model  weight
