萨中地区复合离子调剖剂深度调剖效果

摘要

This paper summarises the selective principle of profile control wells and method to select wells and layers according to the research on the geologic characteristics and dynamic characteristics of poorly affected wells during polymer flooding in Sazhong area. After the analysis and evaluation to profile control results of different polymer injection phases in these years it puts forward the opportunity to perform polymer injection and problems needed to be further studied. This article lays a foundation for the improvement of this technique.%在研究萨中地区聚合物驱油低效井地质特征和动态反映特点的基础上，总结了一套调剖井选井原则和选井选层方法。通过对不同注聚合物阶段调剖效果的分析和评价，提出了今后聚合物驱调剖时机的选择方法和需要进一步研究的问题，为该项技术的逐步完善提供了实践依据。
