Study and Field Application of Multiround Profile Control for Injection Wells

摘要

In this article, multi-round profile control in heterogeneous reservoir through plate models and parallel sand pack experiments are developed. It is confirmed that there is a decreasing effect with increasing round in multiround profile control for injection wells and 5 decline mechanisms are obtained from physical simulation experiments. At the same time, the related improvement technology for the previous problem was also proposed. This technology was applied in the South Tuo 11 block of the Shengtuo oilfield with good effect.
