摘要
聚合物驱油效果受多种因素的影响。聚驱后期,由于在聚合物的长期作用下,地层本身的部分属性发生了变化,影响开发的各因素主次轻重也发生了变化。通过A油田B油层聚驱后期9口中心采出井的累积增油的影响因素分析,应用灰色关联法确定了各个影响因素的关联度大小排序为:采出井的地层系数>连通井的注入浓度>连通井的注入强度>阶段初期含水率>采出井的砂岩厚度>累积注入量,为今后开发调整提供了依据。
The result of the polymer drive is effected by various factors. In the end of the polymer drive, a part of the formation properties have changed due to chronically effect of the polymer, so do the influencing factors order. By analyzing the influencing factors of cumulative incremental oil of 9 oil wells at the center square area at the later stage of the polymer drive of small layer of B reservoir, the grey theory system is used to ascertain the order of the relationship of the influencing factors ： formation coefficient of the output well 〉 input concentration of the connect well 〉 input intensity of the connect well 〉 the water cut of the initial phase 〉 thickness of the sandstone of the output well 〉 the total injection volume, to provide reference for comprehensive development adjustment in future.
