摘　　要：油田注水开发过程中,如何确定注水井分层注水量是油藏工程师们关心的问题.通过对注水井分层注水量劈分的影响因素进行分析,采用灰色关联分析方法确定出影响劈分系数的主要因素及其在劈分系数中所占的权重,实现了劈分系数中各影响因素之间的定量化对比,确定了注水井分层注水量公式.方法考虑了措施改造系数、射开砂岩厚度、注采井距、位置系数和注采井数等因素对劈分系数的影响,确定了注水井分层注水量公式,符合实际的开发特征,能够实现注水井科学、合理的配注.结合S区块目前注水开发过程中存在的层内矛盾及层间矛盾突出等问题,提出了分层注水的必要性,通过灰色关联分析方法确定了S区块的分层注水量公式,实现了区块的合理配注,对其它油田或区块注水开发具有一定的指导和借鉴作用.How to determine the separated layer water injection is a problem which reser- voir engineers concern in waterflood development oil field. This article analyzes the various influential factors of dividing coefficient approach,using grey correlation analysis method to determine the dominant influential factors. And the weight of different dominant influential factors is determined,which realizes the quantitative comparison among them in dividing coef- ficient formula. This method considers the impact of these factors which consist c f the measure reformation coefficient, perforation thickness, injector producer distance, location coefficient and the number of injector and producer. The separated layer water injection formula is de- termined. The scientific and reasonable injection allocation is realized. The problem which the contradiction exists in the same layer or between the layer and layer is obvious in the S block through combinating with the current water injection development. Raising the es- sentiality of sratified water injection.Determining the formula for stratified water injection by grey correlation analysis method in Block S.These factors considered are more with the actual situation, realizing the reasonable injection allocation.It is directive and referenced for other oil field or block.
