摘要
塔河油田注水指示曲线的应用,一般能反映储集体以及裂缝等油藏特征,指导后期注水工作以及措施作业。随着单井注水量的不断优化调整,很多油井在注水期间出现了指示曲线走平的特征,根据物质平衡原理解释,注入水在亏空被弥补后出现外溢。走平井的出现对我们后期注水替油开发具有一定的指导作用。
Abstract
The application of water driving curves in the Tahe Oil Field reflects some reservoir characteristics such as reservoirs and fractures, which could guide water driving in field works. With the optimization of single well water injection, injection curves become flat in many wells, indicating for water spillover after energy supplement. The experience from these wells can guide future water injection.
