注水开发后期中高渗油藏储层特征分析

Analysis on reservoir characteristics of middle and high permeability reservoirs in late development of water injection

本文对注水开发后期中高渗油藏储层特征进行研究。油藏注水开发过程中,各项参数是一个变化的过程,尤其中高渗油藏在高采出程度和高含水的开发后期,储层物性及重要参数发生了明显的变化,本文通过dg油田重要油井的生产历程,对注水开发后期储层物性特征进行总结分析,为后期油藏开发方案编制的准确性提供参考。

In this paper,the reservoir characteristics of middle and high permeability reservoirs in the later stage of waterflooding development are studied.
